Talking The Talk

But not walking the walk (and making it harder for other people to trudge the path, too.) The not-in-my-backyard brigade continues to put up obstacles to energy alternatives. Question--Do we want renewable energy, or not? Yes? Then stop making it so goll-darned difficult to implement!!

Fun With Fungi

"There's noothin' more I cen do, Cap'n. Ahv tried everthin'. Radiation levels are at critical, and soon our skin will begin meltin' froom ahr boohns. I'm sorey, Cap'n, yer gunta havta fire me." Scotty hung his head in shame as he finally admitted the unthinkable. He really didn't have a magical solution to the radiation that was flooding the ship from the ruptured nuclear-coolant-injector. He had nothing involving a revolutionary new matter/anti-matter mixture, or reversing polarity on the containment fields, or even an alien technology he could graft into the Enterprise's systems on short notice which would somehow just happen to have a compatible operating system and a nuclear-coolant-injector-failure failsafe button. No, this time there was truly no hope.

Scotty wasn't alone in his inability to pull a routine miracle out of his engineer's hat. The rest of the crew was failing just as spectacularly. The red-shirts had already gone the way of all red-shirts. Sulu, Uhura, Chekov and O' Reilly had all gone mad from the radiation exposure, so they were equally useless, having already dismantled the ship's navigational and communication systems in an insane attempt to simulate a fifteenth-century karaoke bar. (The first thing that goes with radiation-induced madness apparently being awareness of the historical time-line.) Despite all his protestations that he was a doctor, not a lounge singer, Bones didn't have a miraculous injection to inoculate the crew from the radiation leak using a quadrotriticale-based tribble-blood extract, and even Spock, after a brief but disastrous attempt at a mind-meld with the nuclear-coolant-injector, had receded into an impotent lump, content to stroke tribbles and listen to Chekov's rendition of "Back in the USSR," while Rand tried to get everyone to look at her legs.

Although Kirk found it difficult to focus on anything but Rand's lower appendages, he knew that with the rest of the crew so incapacitated by inadequacy, it was up to him to save the ship. Again. (He also thought that when he got back to Star Fleet he ought to look into hiring some more competant officers, but that was only a fleeting notion.) Back to the task at hand--saving the ship. Again. (He started to play the mental tape about finding some new officers, but then he realised he had just done that.) Okay, really back to the task at hand now. He spent a few minutes looking conflicted and dramatic, ocassionally putting some very strong emphasis into his ongoing monologue. For some reason, dramatic monologues were the best way to kick-start his thought processes. He wasn't sure why, but he just seemed to be wired that way.

After a particularly lengthy and dramatic monologue, during which Uhura had enough time to give a stirring rendition of "Endless Love", and the trio of Chekov, Sulu and O'Reilly managed to throw together a fair performance of "Born to be Wild," suddenly, it came to him. Of course, why hadn't he thought of this before? He took just a moment for a manly pose, and then called down to his defeated engineer, "Scotty, release the fungi!" "Ehr yeh shoor, Cap'n? Ah dunna know what that'll doo." "Just do it, man," the Captain cried, "We've got no choice. It's the fungi, or death." "Aye Cap'n," Scotty said resignedly, and slowly his hand reached out and pressed the fungi-release-button.

What nonsense, you must be thinking (and if you're not, maybe you should go back and read the part about fifteenth-century karaoke.) Of course it's nonsense. Well, most of it anyway. Can you guess which part of our Star Trek adventure has any basis in the non-nonsensical world? I bet you can. It's the radiation-eating fungi, of course!! Believe it or not, there are actually three known forms of fungi that convert radiation to energy the same way plants convert sunlight to energy. The main difference between them is that plants use chlorophyl for the process of photosynthesis, while the fungi use melanin (you know, the stuff that determines your skin color) to perform what I suppose I must call "radiosynthesis."

David Ewing Duncan, at Technology Review (an MIT publication), explains that this radiation-eating fungi could prove a boon in many ways, including as a nuclear clean-up crew, a food source in space, and a new form of biofuel. Versatile little critters, eh? Who would've thought of fungi as a potential source for alternative energy? It'll be fun to watch where this one goes.

I probably should wrap up our space adventure now. Using the radiation-eating fungi, Kirk managed to stave off the imminent destruction, although not in time to avoid a very bad rendition of "Bitter Dregs," performed by Spock and the tribbles. Uhura is now headlining on Wriggley's Pleasure Planet, whenever the Enterprise heads into that region of space. Stay tuned for our next episode with Kirk and his crew (who do manage to hold onto their jobs, by the way), in which we will probably have to deal with what happens when the fungi, fed by massive amounts of radiation, grow to sentience and try to take over the Enterprise. For now, let's just say there won't be karaoke, but there will probably be lots of monologues, and Kirk will have to save the ship. Again.

Wave Power II

I got a comment last night on an old (and rather silly) post I wrote last October, about new technology being developed to extract some of the massive amount of power that's moving around in Earth's oceans. A company called Biopower Sytems is designing generators that work with the flow of the oceans to harvest that energy, and their technology shows some real promise. Nick Bruse, the commenter in question, left a link to his podcast, called The Cleantech Show, in which he interviews Biopower Systems' Founder and CEO Dr. Tim Finnigan. I found the interview fascinating, and was encouraged on several levels. Dr. Finnigan seems to have a clear vision for where his start-up company is headed, solid engineering to back up his hopes, and a realistic view of where renewable energies will fit into the world's complete energy package. The whole interview is half an hour long, and well worth a listen, so here's the link. I found Bruse's interview style to be relaxed and informative, and I'll be checking out what else he's found that's happening in the wonderful world of clean technology. Thanks for the heads up Nick!

Synthetic Biology II

There is some seriously next-level science going on in the world. Lee Silver at Newsweek has a fascinating article on where scientists are taking the quest to create build-your-own biological organisms, designed to do everything from growing hard-to-produce medicines, to acting as internal cancer-killing machines that live in your bloodstream and seek-and-destroy any and all tumors. Scientists envision synthetic biological critters which create plastic, wool or silk as a by-product, and "biodevices" that detect radiation, anthrax and other dangers. One of the goals with the most world-changing potential is a living organism that secretes fuel, "a self-sustaining, highly efficient biological organism that converts sunlight directly into clean biofuel, with minimal environmental impact and zero net release of greenhouse gases."

The kicker to all these lofty goals is that the biggest of them can be best accomplished if scientists come up with a way to manufacture life from scratch, rather than tinkering with the life that's already hanging around the planet. There's progress happening without that leap, but there's a lot of extra coding that gets in the way. There's also progress that's happening in the putting-the-building-blocks-together department. Scientists have done some amazing things:

They've forged chemicals into synthetic DNA, the DNA into genes, genes into genomes, and built the molecular machinery of completely new organisms in the lab—organisms that are nothing like anything nature has produced.

All of this, however, does not add the spark that makes something alive. They can mess like crazy with what's already there, but they haven't crossed the boundary into "creating life," although, that is certainly their aim. I will be really interested to see whether God allows scientists to put life into something where there was no life before. Sceptical, but interested. (It's still wouldn't be real creation. At a basic level, the matter of the universe was already created, regardless of what we do with it afterward.) According to Silver, scientists are on the brink, and they certainly are performing monumental feats with the newly acquired knowledge of genes and DNA and the like that has transformed science over the last half century. Will God grant them the ability to step beyond tinkering and into the realm of kick-starting life? I have no idea, and so I'm not as sanguine about all their grand schemes coming to fruition as some of the scientists who are working on synthetic biology seem to be, but even without that truly unique element, what they are already doing is astounding, even to the point of being scary.

There is so much good that could be done, but also an enormous amount of room for abuse, not the least of which is the potential for critters that have been tampered with running amuck in the world, doing things they weren't intended to do by the humans who are taking it upon themselves to redesign nature. Whether created by God and reconfigured by man, or entirely lab grown by human design (if God allows that barrier to be crossed), these human designers need to tread carefully. The idea of taking some newfangled critters, adding sunlight, and fueling the world is totally captivating, as is the notion of eliminating cancer, and the Newsweek article really is fascinating, but my alarm bells go off when I start reading about people whose attitude is that of James Watson, co-discoverer of DNA structure, who, as quoted by Silver, said, "If we don't play God, who will?" I'd be more comfortable if the people who are on this quest were a little more afraid of the outcome.

A New Notion In Motion

Remember playing on the merry-go-round as a kid? I'm not talking about the fancy amusement park version, with the pretty horses and dolphins and bench seats for the grandparents. I mean the big spinning metal plate, with waist high tubes coming out of the center likes spokes in a horizontal wheel, that you hung onto for dear life when the big kids got to running really fast around the outside to make the fun-machine go. It could be quite a ride, and a dangerous one at that, if you didn't station yourself at one of the inside spaces that had a protective bar to hold you in place. Of course, being on the outside was the best "ride," because that's where you really experienced the speed. This was a mixed blessing. I remember once being on the outside of a full merry-go-round during a busy day at the park, and the speed got so high that my feet got swept off the thing by the centrifugal force, and I actually was pulled under the rim as the joyous death machine spun above me. It was scary, and dampened my enthusiasm for spinning, probably laying the psychological groundwork for later years of motion sickness. I now tend to think of that particular piece of playground equipment as a merry-go-flying. Do they even have them in public parks anymore? I would think in this age of PC lawsuits they would have been banned by the "concerned citizens for helmets, padding and reflective tape brigade."

What those merry-go-rounds really needed was a protective barrier on the outside to keep the little people firmly on board. You never hear of diners flying out of the restaurant at the Space Needle do you? That's because there are walls, obviously, and because the restaurant just doesn't spin that quickly. There's also none of that jarring velocity shifting that happens when the motion comes from an irregular power source like the legs of a twelve-year-old kid. No, nice steady electrical current works much better for turning the top floor of a building, especially a restaurant. You end up with much less soup in your lap that way. (Not that I wouldn't end up wearing my soup anyway. I am a notorious food klutz, and have yet to make it through an entire day as an adult without dropping something of the food variety onto myself, the floor, the table, or any other unfortunate surface that happens to be in the vicinity when I am eating or preparing food, but I digress.)

Think about the dynamics of applying an inconsistent, and sometimes violent, source of power to turning an entire story of a building. What if the restaurant at the Space Needle were powered by wind, like a giant windmill? Not only would the motion be inconsistent, potentially spilling the aforementioned soup, but it would also be unreliable. Some diners might get swept around so fast that the nearby scenery whipped by in a blur, while others, who came on less eventful weather days, might have to be content to stare at the parking lot because the restaurant was in stagnant mode. Even if the building in question didn't contain a restaurant, but was an office building instead, it would take some physical and mental adjusting to the fact that sometimes you would be moving, and sometimes you would be sitting still--and occasionally you could be jerking from one to the other. It might be a little freaky. Needless to say, some people might actually like it; I'm just assuming it wouldn't be for everybody.

Now apply that notion of wind-powered motion to every floor of a skyscraper, each spinning independently, according to the wind-speed at its own altitude. Sound too "out there?" Why would anyone build a windmill building anyway, and could such a thing actually make it off the drawing board? Ask the folks in Dubai, who are planning to start building a "windscraper" within the next six months, or the folks in Chicago who have the same notion. The primary reason? According to Ben Longo at Gizmodo, one of these buildings could power itself and ten other buildings with its revolving floors--as long as the weather holds, that is. (In that regard, this seems like a good fit for the Windy City, don't you think?)

I assume self-generating power isn't the only motivation for the windscraper notion. Some people will pay a lot of money for a really good view, and it's very likely that an ever changing panorama would be worth a pretty penny to rich people with strong enough stomachs to handle the inconsistency of the ride. I'm guessing that strong stomachs won't be the only requirement. They probably will have to take other things into account to accommodate the motion, too. For example, no wheeled chairs, or carts, or appliances allowed, or every time the wind picks up some one's going to have to chase down the furniture that rolled toward the outside of the building. No high heels in that environment, either. It's just too risky. I would also strongly suggest sippy cups.

Go have a look at the Gizmodo post. There are artist's renderings of the building conceived by architect, David Fisher, and a video to give you a better notion of what the idea involves. As a firm believer in the desirability and potential of alternative energy, I find this notion intriguing, if somewhat ambitious. Hey, if it works, more power to 'em. Just don't ask me to move into one of these buildings. I might go for a ride, just to check it out, but let's make it a short one. I still haven't gotten over that traumatic merry-go-round experience as a child. That, and I really am getting tired of spilling my soup.

Hey, I Was Right!!

It's not often that I feel the need to quote myself, but I predicted something scientific and space-related that might actually turn out to be true, and now I have to revel in my brief moment of rightness. Back in July of 2006, I read a report from NASA that the Cassini spacecraft had found evidence for lakes of liquid methane on Titan, one of Saturn's moons. I took a mental leap--not a huge one for the real sciency types, but a respectable leap for me:

Scientists will continue to observe the areas, looking for evidence like changes in size, or surface roughness stirred by winds, to indicate whether they've guessed correctly. If they're right, Titan is "the only body in the solar system besides Earth known to possess lakes." Not exactly the place you'd want to go for a summer vacation. One usually heads to a lake for fresh air and exercise, but Titan's not really a fresh air environment, is it? All that methane and ethane might make it a little hard to head out for a hike, or row a canoe, wouldn't you say? What a shame; it would be such an adventure to head to a lakeside cabin off-world. Oh well, there's got to be a bright side, right? Hmmm, liquid methane...liquid methane...sounds like a possible built-in fuel depot to me. That's it!! Titan can be the gas station on the way to some other cool vacation spot that we'll discover any day now. It's not quite as fun as finding Shangri-La on some other planet, but it will have to do.

My big prediction, somewhat flippantly expressed, was that someday Titan's lakes could fuel our journeys to other exciting destinations. Guess what? NASA thinks I'm right!! Well, okay, NASA doesn't know anything about me and my little bloggy predictions, but I can at least say that NASA agrees with me. NASA is testing a methane rocket engine, hoping to take advantage of the abundance of methane just waiting to be harvested from our neighboring planets. Patrick Barry, writing at NASA's Science website, says that methane engines "could eventually be key to deep space exploration."

Some of the advantages to the methane engine include the fact that liquid methane can be stored at a higher temperature than liquid hydrogen (the current fuel of choice for the soon-to-be-retired space shuttle.) This would mean less insulation, and thus less weight to haul off of planet Earth. Liquid methane, according to Barry, is also denser than liquid hydrogen, which would make the fuel tanks smaller, lighter and, ultimately, cheaper. Barry quotes project manager Terri Tramel of NASA's Marshall Space Flight Center as adding safety to the list of methane's perks:

Methane also gets high marks for human safety. While some rocket fuels are potentially toxic, "methane is what we call a green propellant," Tramel says. "You don't have to put on a HAZMAT suit to handle it like fuels used on many space vehicles."

Here's the gravy, though, as far as the NASA-proving-me-right part of this little self-congratulatory post goes. In our solar system, methane is basically ubiquitous, so rockets wouldn't have to carry fuel for the whole journey along with them. They could pick some up along the way:

But the key attraction for methane is that it exists or can be made on many worlds that NASA might want to visit someday, including Mars.

Although Mars is not rich in methane, methane can be manufactured there via the Sabatier process: Mix some carbon dioxide (CO2) with hydrogen (H), then heat the mixture to produce CH4 and H20--methane and water. The Martian atmosphere is an abundant source of carbon dioxide, and the relatively small amount of hydrogen required for the process may be brought along from Earth or gathered in situ from Martian ice.

Traveling further out in the solar system, methane becomes even easier to come by. On Saturn's moon Titan, it is literally raining liquid methane. Titan is dotted with lakes and rivers of methane and other hydrocarbons that could one day serve as fuel depots. Imagine, a methane-powered rocket could allow a robotic probe to land on the surface of Titan, gather geological samples, refill its tanks, and blast off to return those samples to Earth. Such a sample-return mission from the outer solar system has never been attempted.

The atmospheres of Jupiter, Saturn, Uranus and Neptune all contain methane, and Pluto has frozen methane ice on its surface. New kinds of missions to these worlds may become possible with methane rockets.

So, Titan may well turn out to be an interplanetary gas station, as well as a geological destination-of-interest in its own right. Speaking of destinations-of-interest, head over to the NASA article if you want to watch the video of the new rocket in action in the Mojave desert. It's way cool, and downright pretty, with this really impressive blue flame. They're still working on the project, with tweaks to be done before a methane-fueled rocket can blast off the launchpad, heading for fabulous holiday destinations like the Lakes of Titan, but the pretty blue test was a promising start.

The best part of all this scientific and spacey advancement, from my perspective? I got to be right! (Hey, cut me some slack. It doesn't happen that often.)

Beer--It's Not Just For Drinking Anymore

This is funny, in a "good idea" kind of way. You've heard of beer batter? How about a beer battery? (via Popular Mechanics)

Breaking The Laws Of Physics?

Picture this: You live in a world with unlimited energy resources and next to no pollution. No one freezes in winter, or roasts in summer anymore. No one starves either, because food production, transportation and storage have become almost universally affordable, due to those previously-mentioned unlimited energy resources. Cars not only cost less to make and drive, they run forever without needing the tank filled. In fact, there is no tank, because there is no gas, because the cars don't need it anymore. How's it sounding so far? It gets better. International relations are changed forever. There's no more kowtowing to tinpot dictators because their country happens to sit on top of abundant oil reserves. (There aren't even any more "evil" oil companies, because, as I mentioned earlier, there's no more need for oil and gas.) Space travel becomes commonplace with all that unlimited energy to lift us out of the gravity well. Humans settle colonies from the Moon to 581c, and unite to create a Federation of Planets that bring abundance and prosperity to far-flung alien worlds. Universal peace and brotherhood overcome all the conflicts of mankind, worlds without end. Well, okay, that last bit is just plain ridiculous; people will always find things to fight about, unless the whole sin thing goes bye-bye.

Does all this sound like some ultra-sappy massively idealistic science fiction plot? Of course it does. Everybody knows there's no such thing as unlimited energy. Or is there? What if some people have actually pulled off the impossible, and created a perpetual motion machine, that not only puts out more energy than is put into it, but actually puts out 400% more energy? Wouldn't that transform the world almost as completely as any massively idealistic science fiction plot could envision? (Let's put aside for now all the inevitable sci fi counter-plots that are sure to spring up, in which evil oil empires do everything in their petroleum-enhanced power to destroy the new technology and everyone who ever saw the plans for it. Let's just take it as a given that the oil people either aren't as evil as conspiracy theorists paint them, or that they are too incompetent to pull off the destruction of the future hope of all mankind. Anything else takes us too far down rabbit trails which don't fit into my desired scenario, and it's my blog, so I get to write what I want. You can complain and pose alternate options in the comments if you like.)

Okay, now that we've determined the outcome of the invention of the perpetual motion machine, let's talk about who would be loopy enough to announce to the world that they've accomplished something that flies in the face of physics as currently understood by the people who understand such things. The company making the claim of this breakthrough is an Irish enterprise called Steorn, headed by CEO Sean McCarthy. According to their website, "Steorn is a leading Intellectual Property development company. Our latest development is Orbo, our magnetic energy generation technology." It is this magnetic energy generation technology that Steorn claims, "...is a technology that produces free, clean and constant energy. It can be applied to power products ranging from portable music players to cars." The company says they will make it available, after scientific validation in July, for free, allowing developers to design products built around their promised physics-defying breakthrough. Is this a sci fi kind of scenario, or what? Not only does it seem that these people have developed the answer to many of mankind's problems, but they want to give it away. It's really not possible at this point not to ask, "What's the catch?"

The catch is that Steorn is claiming they have done something that most scientists insist absolutely cannot be done. Gizmag explains it like this:

In science, the term efficiency is used to describe the discrepancy between the energy that goes into a system and the useful energy output of the system. The first law of thermodynamics states that, because energy cannot be created or destroyed, efficiency cannot exceed 100%. The second law states that, since matter and energy are constantly progressing towards a state of equilibrium with the environment, the efficiency of a system will inevitably deteriorate. Steorn, however, asserts that the “meticulous” placement of magnets can allow a magnetic object to progress indefinitely along a path in such a way that when it returns to its starting position, it has gained energy. McCarthy claims that such an arrangement can result in up to 400% efficiency. This system breaks the laws of thermodynamics with such blatant contempt that, in a Newtonian universe, all Steorn members would be thrown in physics prison. Indeed the devil-may-care attitude Steorn’s prototype has towards the universal constants is part of the reason the company had such trouble in their initial attempts to persuade scientists to test it. McCarthy claims that 90% of scientists they approached refused to even acknowledge the possibility. As for the 10% dared to witness it in action, McCarthy states that all were convinced.

The consequences for the world, if McCarthy and the still anonymous 10% are correct, will be nothing short of epic. Not only would it be a falsification of the laws of physics, it would provide infinite, free, clean energy for the entire global population. It would almost eliminate pollution, provide power to the hundreds of millions of people who currently live without it and could feasibly construct a society where the essential needs of the people are automatically taken care of.

Wouldn't that pop the lid right off the popper? Many think this is a hoax or a scam, but Gizmag makes a good case for Steorn having little incentive to fool the public, and an established business to lose if they sacrifice their reputation for fifteen minutes of infamy. This one is worth reading for yourself, folks, so head over to catch the rest of the Gizmag article. Then we wait till July for the "public unveiling." Will July plant the seeds for a massively idealistic science fiction future, or will the laws of physics prevail? Tune in this summer for further developments.

Fun With Alternative Energy

Okay, this could be a lot of fun:

A thin film of plastic which conducts electricity and produces solar power could be the basis for a revolution in the way we light our homes and design clothes.

They're talking about OLEDs here--organic light emitting devices. How you ask, could that possibly be fun?

Because the devices are thin and flexible, lighting and electronic display screens could for the first time be created on almost any material, so that clothes and packaging can display electronic information.

What's not fun about that? Not enough information yet? Need some examples?

The devices' uses could vary from lighting that is many times more efficient than current bulbs to clothes whose colour can be changed at will and beer cans that display the latest football results.

Fun enough for you? So how is that possible?

The devices exploit a discovery made around 15 years ago that some polymers have the unusual property of either turning electricity into light, or light into electricity, depending on how the devices are made.

Are there cool and practical uses for this technology--amazing things like an alternative energy source that can be rolled up and carried along on a mountain trek, windows that double as lights at night, and electronic clothing for emergency personnel that can have updatable messages written across them in glowing letters? Yep. Wouldn't such clothing be fun at parties? Again, yep, but none of this stuff is really ready yet. Research happens.

More Nano Power!!

Last week I told you all about the thrilling new nanotechnology development that may soon let your walking shoes power your iPod. It was such an exciting thing to learn that I know that you are dying to find out what else is going on in the wonderful world of nanotech. The yearning for more nano-knowledge is probably gnawing at you even now, and you feel very much like the desperate person who has been given a single tantalizing bite of cheesecake, only to see the rest of the delightful dessert accidentally upended onto an anthill. The suffering is, no doubt, intense. I simply can't be responsible for that kind of discomfort. The mere thought pains me, so today I will ease our mutual misery by bringing you news of yet another new nanoventure, only this one will be "better, stronger, faster," like Steve Austin after the upgrade. Last week's nanopower invention could run a cellphone; today's nanopower invention could possibly run satellites, or other spacecraft.

Our old friends, carbon nanotubes, having achieved near-universal-usefulness status with their extreme strength and lightness, are trying to further their foothold on ubiquity, by making their way into the realm of solar power. John Toon, writing at Georgia Tech Research News, explains how 3D solar cells, constructed using carbon nanotubes, could change the shape of solar, and thus of spacecraft power:

Unique three-dimensional solar cells that capture nearly all of the light that strikes them could boost the efficiency of photovoltaic (PV) systems while reducing their size, weight and mechanical complexity.

The new 3D solar cells capture photons from sunlight using an array of miniature "tower” structures that resemble high-rise buildings in a city street grid. The cells could find near-term applications for powering spacecraft, and by enabling efficiency improvements in photovoltaic coating materials, could also change the way solar cells are designed for a broad range of applications.

“Our goal is to harvest every last photon that is available to our cells,” said Jud Ready, a senior research engineer in the Electro-Optical Systems Laboratory at the Georgia Tech Research Institute (GTRI). “By capturing more of the light in our 3D structures, we can use much smaller photovoltaic arrays. On a satellite or other spacecraft, that would mean less weight and less space taken up with the PV system.”

You caught how the 3D nature of the little solar towers catches more of the light, right? Not only is there more surface area to absorb the photons, but the grid "traps" the light, rather than letting it bounce off the surface, as occurs now with standard solar panels. Light can bounce within the towers, allowing the new system to capture more of the photons--"virtually all of the light that strikes them." The towers also absorb sunlight coming from any angle, so the sun doesn't have to be directly overhead for peak efficiency. In fact, according to Ready, these towers become more efficient when the Sun's light isn't coming directly at them.

Satellites could see a major upgrade as a result of this directional versatility. Since their solar panels would no longer have to face the light directly, the mechanisms wouldn't have to be in place to turn them all day long, like a giant photon-collecting rotisserie. This is a big improvement. The Air Force, aware of the advantage this new system could provide, has been funding some of the research related to this project. Satellites that don't need extra bells and whistles to keep their solar collectors turned to where the Sun shines could be smaller, lighter, and cheaper than their ancestors. ("Smaller, lighter, cheaper" is the carbon nanotube addendum to "better, stronger, faster.") All of the above applies to other Sun-fueled spacecraft as well. Probes, cameras, space stations, commercial spaceliners and space hotels could all benefit from harvesting more of those useful photons emanating from the Sun.

Space isn't the only place where this technology could improve photon collection. Earthly solar panels could get a big boost from the improvement to their efficiency. According to Maria Surma Manka, at Green Options, the new way of structuring solar cells could up their juice output significantly--"These three-dimensional panels produce about 60 times more current than regular solar cells. " Wow. 60 times more current? That could give solar power a much higher usefulness quotient, don't you think? All those panels mushrooming on the roofs of Californians might soon get a whole lot more effective at powering the houses below them. It might even make the mushrooming spread to other territories. I wonder if the nano-enhancements would make solar power have potential even in soggy places like Oregon? (Don't mushrooms like it damp?) Wouldn't that be an incredible feat? A solar-powered Oregon. Only carbon nanotubes could pull that off.

God did a good thing when He invented carbon nanotubes.

Nano Power!!

It's been a while since I read anything fun about nanotechnology, so I went hunting today. Searching high and low, I combed the Internet for any signs of life in the nanoworld. Okay, that's a massive exaggeration. All I did was head over to LiveScience.com and peruse their latest headlines. This one by Bill Christensen--"Tiny Generator Would Make Electricity While You Walk"--sounded promising. What's the first thing anyone learns about nanotech? It's tiny. So, I clicked my way on over to see whether these "tiny generators" were small enough to qualify for nano-status.

They do, indeed. What I found was a nifty new accomplishment by Professor Zhong Lin Wang of the Georgia Institute of Technology:

Wang has created a tiny nanogenerator that produces a continuous flow of electricity by harvesting mechanical energy from its surroundings. It can produce energy from ultrasonic waves, mechanical movement or even blood flow.

Christensen explains that Wang's tiny power plants are constructed of lots of little wires which flex with the motion around them. The flexing builds an electric charge in the wires, which when moved enough to contact a "collection plate," deposit their electric load. Enough of those wires added together can gather tiny amounts of direct current. We are not looking at lighting Chicago with this method of electrical generation. We're not even talking about lighting your house. However, some of the little electronic devices most of us rely on every day to ease our way through the modern world, like cellphones and iPods? These we might have a shot at juicing with nanogenerators.

So many things that we do every day create force that goes to waste. We stand up. We sit down. We turn our heads. We drum our fingers. We breathe and blink our eyes. All that movement could certainly wiggle a few wires. Of course, there's the question of how you place those wires and collection plates where they can reap this power whirlwind. No one is going to want eyelid power stations, are they? (Well, some people might, judging by the body piercing craze.) Running electronic devices off of various body implants might be edging us a little closer than we'd like into Borg territory--merging man with machine. However, there are other options. Putting aside the notion of implants, how would you like to charge your phone just by taking a stroll?

Wang and his group believe that the nanowires could produce as much as 4 watts per cubic centimeter. "If you had a device like this in your shoes when you walked, you would be able to generate your own small current to power small electronics," Wang noted. "Anything that makes the nanowires move within the generator can be used for generating power. Very little force is required to move them."

Here's a scenario for you: You crash your car in the middle of nowhere, barely escaping the Hollywoodesque inferno. Miraculously, you are completely unharmed. The miracle is not all-inclusive, however. You go to call for help, only to discover your cellphone is dead--no hope of charging it in your recently-exploded Subaru. (Oh wait, Subarus are supposed to be really safe. Let's make it a Pinto.) What do you do? Why, you start walking toward the nearest town, of course. The phone charges while you're hoofing it, and the rescue team meets you before you can make it a quarter of the way to the local hamlet. (By the way, the walking toward town is a good idea even if it's not going to charge your phone. I mean what else are you going to do, sit there listening to soothing music on your iPod? That's going to have to be charged eventually too, so you might as well get going.)

Needless to say, at some point we'll get over our Borgaphobia and submit to the implants. After all, eventually we're going to find it inconvenient to have those little generators limited to our shoes. What if we want to go for a walk on the beach--barefoot, of course--and we need to make an important call? No, the shoe thing just won't work long-term. Christensen did mention that the nanogenerators could collect power from flowing blood. I think the answer will be miniature floating power stations, circulating around in our bloodstreams. While they're at it, they can check our blood sugar, and clean our arteries, and balance our hormones, and... You get the picture. I think we should put them in dogs, too. The power they generate could run yet-to-be invented electro-gadget dog collars that keep Phydeaux from running away, and peeing on the carpet, and other important pet/pet-owner bones of contention. I'm sure if we think about it hard enough, we will also find a way to use these bloodstream nanogenerators to solve all the world's other problems, including terrorism and halitosis. There is just no limit to the benefits of nanotech.

Show Me The Green

Here's a "money where your mouth is" opportunity for Al Gore. Rick Haglund, at mlive.com, suggests that the former V.P., turned environmental advocate, could revolutionize the auto industry:

It's time for him to stop relying on the bully pulpit and the big screen, and put some skin in the game. He should buy Chrysler, which parent DaimlerChrysler put up for sale in February, and make it the greenest automaker on the planet.

Dump Chrysler's gasoline-fueled internal combustion engines altogether and replace them with fuel cells, electric motors and engines that run on biofuels, such as ethanol and biodiesel.

Haglund thinks Gore could raise the cash to buy Chrysler by tapping into all the celebrity eco-consciousness, and environmental activism, and that his political connections and Democratic union ties could serve him well in making a go of turning the auto industry green. The theory is that if one company can do it at a profit, the others will follow.

Interesting idea. I wonder if there's any chance that some such thing could ever happen, not specifically with Mr. Gore, but with any of the big money environmental champions who want to change the way America gets around? They say the best way to lead is to go someplace first yourself. If it really is possible for auto makers to "eliminate the internal combustion engine over the next couple of decades," as Gore contends, then what better way to prove it than to be willing to be the one taking the financial risks to make it happen?

"Exploiting The Jet Stream"

Looking for something new on the energy horizon? How about something new from something old? For your economy-and-ecology-friendly power-producing pleasure, I offer you the flying generator. That's right--there are alternative energy ideas currently taking flight that give a twist to that merry childhood plaything: the kite. These flying generators are designed to take advantage of the fact the wind blows a lot harder and more steadily way up high, up where the weather moves. All that power blowing around over our heads could be lighting cities here on the ground--if we could only capture it--and Economist.com has the story of more than one engineer who believes that he's found the answer to doing just that. Won't it be cool if they can pull it off--as long as they can keep the birdies and airplanes safe, that is?

Just as a side note, from a "decorating the sky" perspective, it would be extra cool if the flying generators can have streaming tails with colorful bows on them, too, just like real kites. They might as well make them pretty while they're at it, don't you think? Have you seen some of the land-based wind-farms? Visual blights, every one. I vote for flying generators with style. Anybody else agree, or am I flying solo?

The Power Of Hydrogen

I followed a link from Instapundit this afternoon about a new concept car from Ford that is, according to Popular Mechanics, "the world’s first working plug-in, fuel-cell, hydrogen-powered car." That was pretty cool--a real car with hydrogen fuel-cell power. I wanted a ride. The short little blurb about Ford's new hybrid then sent me on a rabbit trail to an article from the November 2006 issue of Popular Mechanics. It's a very interesting primer on the current state of Hydrogen fuel technology, examining hydrogen as a source of power, its transportation and storage, practical uses, and also the various sources for that hydrogen. I'm not going to synopsize the article; although it's not horribly long, there's an awful lot packed into it, and Jeff Wise at PM has already done all that work. It would be a shame to duplicate his efforts when I really have nothing useful or entertaining to add. I will, however, encourage you to read it for yourself. Wise explains lots of things I never knew before about the mechanics of getting energy from hydrogen, the environmental cost of current methods of hydrogen production, the history of hydrogen technology (it's been used on the space shuttle for decades) and where it's headed, including a look at infrastructure. If you're curious how close we are to a hydrogen economy, go have a look.

Note: Popular Mechanics is also promising a cover story in May on the future of plug-in hybrids that ought to be interesting. I'll try to keep an eye out for it. Let me know if you spot it first.

An X Prize For Fuel Economy

Y'all remember the X Prize, right? $10 million went to the team that built the first private spaceship to make it to space. The contest prompted big advances in the baby private-space-flight industry, and continued X Prize-type challenges keep spurring the new industry forward. Now there are not only private companies contracting with NASA to take payloads into space, but there are many companies working on various commercial space projects, from space hotels to space elevators. This financial incentive thing gets people involved--and gets results. $10 million can certainly give little guys with big ideas some incentive.

So, what about applying that principle for more Earthly goals? Nick Bunkley, at The New York Times is reporting that the X Prize Foundation is set to offer even more than $10 million to whoever can develop the first "commercially viable car that can travel 100 miles on a gallon of gasoline." They're not looking for pie-in-the-sky here. They want to prompt the development of vehicles that would work and be affordable in the real world.

...the organizers want to ensure that vehicles entered in the contest, which will compete in races in 2009 to determine the winner, are commercially viable. Entries must be production-ready, unlike many of the fantastical concept cars that are presented at auto shows. Each team must prepare a business plan for building at least 10,000 of the vehicles at a cost comparable to that of cars available now.

100 miles to the gallon of gas, and an affordable car to boot? That would make it possible for folks here in Portland to drive all the way to Disneyland (a very important destination) without stopping to fuel up. Wow. Sounds almost too good to be true, and if it weren't for the competition and financial incentive, I doubt this would go very far. Bunkley explains that the problem isn't making a car that can get 100 mpg, but in making that car at a price people can actually afford to pay. The industry is not currently geared for the rapid changes and big risks necessary to shift from the 20 mpg the average car gets today to the 100 mph that they're aiming to achieve with the impetus of the competition. That $10 million shot in the arm, though, could make all the difference. The X Prize approach has really produced results in reaching for the stars. It'll be exciting to see where this new prize can drive the automobile industry.

Hydrogen Fuel Cells: "On Demand" Energy

Here's an alternative energy tidbit for you. Clean, cheap energy remains the Holy Grail of the modern scientific world (unless you rank the cure for cancer higher.) Among other approaches, ambitious companies are working hard on practical ways to make hydrogen fuel our cars. Bill Hobbs, writing yesterday at Ecotalityblog, says that Ecotality’s Hydratus technology combines magnesium and water, and the reaction between them produces hydrogen "on demand," as a vehicle's fuel cell has need of it. On demand sounds good, doesn't it? So does the idea of a fuel whose only byproduct is water, which is one of the lures of hydrogen as a source of energy, and Hobbs says this new technology can power a bus. The Smart People at Ecotality think they're onto something big.

Now, I'm not a chemist, or a physicist or any other kind of "ist," but I still found the short post about the Hydratus interesting. Although, maybe I found it interesting because I'm not an "ist." So far there are several comments from other Smart People in response to the post, explaining why using magnesium is not a net gain in terms of energy output, requiring too much energy to produce the magnesium which produces the hydrogen, and how there are other byproducts to deal with as well when magnesium is involved. Ecotality’s CEO, Jonathan Read, sounds awfully confident, though, claiming, "Hydrogen on-demand is going to be what catapults hydrogen from being a great concept to a great reality." Maybe the company is one or two steps ahead of the commenters. Smart People debates--fine entertainment for your Wednesday morning. I hope Ecotality comes out ahead on this one, though. It would be nice to see more really tangible advances on the alternative energy front.

Going With The Flow

What's 16 feet wide, underwater, and a new potential source for alternative energy? Hint: It enjoys rainy days and likes to "go with the flow." Give up? It's a "tidal turbine." We've all heard of wind turbines, of course, and most of us have probably driven by the giant wind farms that have sprung up in breezy spots across America (if you live in America, that is.) Well, now there's a sort of "current farm" going into New York City's East River, in a channel where ships don't pass, but lots of water still does. According to Erik Sofge, at Popular Mechanics, "six 35-kilowatt turbines scheduled to be installed by mid-March" will be providing power to a supermarket and a parking garage, and there are plans to add hundreds more turbines, if things go well.

One of the questions this test is designed to answer is whether problems specific to the underwater location, such as barnacles, will be an impediment, or whether the giant rotors will just keep spinning. Water is a force to be reconned with, so I'm betting that current and the grinding of the turbines keep the barnacles at bay (so to speak.) With all that spinning going on, however, there's also concern for river life. This test should also determine whether the river's residents can go with the flow. The designers have tried to make the power producers fish friendly. Just as wind-turbine designs have to take into account the safety of our feathered friends, these underwater ones have beeen built with Nemo in mind. The rotors turn slowly, and have blunt edges, and hopefully that will prevent them from committing fishicide.

If all goes according to plan, and the "current farm" is expanded to full capacity, the resulting power from this one East River location could equal 10 megawatts, which Sofge says could run 4,000 homes. When that kind of potential gets extrapolated across the country, "...our rivers and estuaries could provide up to 130,000 gigawatt-hours per year — about half the yearly production of the country's dams." Sounds pretty exciting, eh? One might almost say electrifying.

Plug It In

Encouraging news on the alternative energy front. James Woolsey, former director of the CIA, writing in the Wall Street Journal, is predicting "major progress toward independence, spurred by market forces and a portfolio of rapidly developing oil-replacing technologies." He explains that the development of alternative liquid fuels is getting a boost, as scientific leaps are changing the fuel production boundaries. Among other advances, new biotechnologies are making it possible to produce ethanol from a wide range of plants other than corn. This is an improvement because growing corn is a very land and fuel intensive process, which limits corn's potential ability to reduce our dependence on fossil fuels. With scientific advances, allowing more fuel production from much less land and far less fuel used in the growing process, production costs for ethanol are declining, and our capacity to produce enough quantities of alternative fuels to be a meaningful challenge to the global supremacy of petroleum-based energy is increasing. This is good news for the new year. I don't think there are many of us who don't see the advantages of a "grow-it-yourself" fuel supply, both for assuring adequate energy resources here at home, and limiting the influence of the often despotic regimes that always seem to be the ones in control of the oil reserves abroad.

Of course, we've seen promises about alternative fuels for years, and the oil producers of the world have had a few tricks up their sleeves. OPEC has driven down prices in the past, effectively driving the competition out of business. Woolsey says this time OPEC may not be able to stifle innovation by lowering oil prices:

The change is being driven by innovations in the batteries that now power modern electronics. If hybrid gasoline-electric cars are provided with advanced batteries (GM's announcement said its choice would be lithium-ion) having improved energy and power density--variants of the ones in our computers and cell phones--dozens of vehicle prototypes are now demonstrating that these "plug-in hybrids" can more than double hybrids' overall (gasoline) mileage. With a plug-in, charging your car overnight from an ordinary 110-volt socket in your garage lets you drive 20 miles or more on the electricity stored in the topped-up battery before the car lapses into its normal hybrid mode. If you forget to charge or exceed 20 miles, no problem, you then just have a regular hybrid with the insurance of liquid fuel in the tank. And during those 20 all-electric miles you will be driving at a cost of between a penny and three cents a mile instead of the current 10-cent-a-mile cost of gasoline.

All of this would have the added advantage, according to Woolsey, of reducing vehicle carbon emissions by 60%, as well. Read the rest. It's a good start to the new year.

Note: The info about reduced carbon emissions reminded me that I wanted to pass on a link to a book I read online a couple of weeks ago. I didn't even have to go to the library. I just turned on my laptop and read the whole thing. The book is Fallen Angels by Larry Niven, Jerry Pournelle & Michael Flynn, and it was completely enjoyable from this sci fi fan's perspective. It's set in the not-so-distant future, when the "green" movement has taken the reins of power, and dramatically changed the world's energy usage. Problem is, it turns out the only thing preventing the start of another ice age was the presence of all those greenhouse gasses coming from the Earth's infestation of humanity!! With the carbon emissions virtually eliminated, the ice age cometh. Science fiction, by the way, is now illegal, and the Earth's governments are at war with "inappropriate technology," including the space stations still orbiting the planet, and their inhabitants. It's a totally fun read, complete with underground sci fi conventions, government goons, and corn genetically-altered to grow plastic. I'd say it was a page-turner, but since I read it online, I guess I'll have to say it was a "scroller" instead. It's lame, but that's the best I could come up with. Oh well.

Wave Power

Frequently, as I surf the web, I am caught up in a wave of excitement when I land on swell advances in the ocean of ideas for alternative power. Here's a current notion, that may hold water, if you can fathom the concept of electricity coming from the deep blue sea. Engineers are making headway on designs that harness the power of waves. Are you thinking of wind-turbines under water, matey? Well, that's not quite the heading they're taking. With scientists at a company called BioPower Systems at the helm, the company is going full steam ahead, with plans to have a pilot program in place by 2008, and commercial units available by 2009, but rather than underwater windmills, the new generators to which they are anchoring their future mimic more seaworthy designs, such as kelp fronds and shark tails. These forward-thinking plans work with the currents in a way that is safe for ocean life. Is your imagination adrift? Here's the link to help you batten down the mental hatches. This should buoy your hopes that the possibilities for alternative energy aren't going to capsize.

If I went overboard with the nautical terms, I hope you'll give me some leeway. I must have temporarily lost my rudder. Please stem the tide of malice, and I'll stow the rest of of the "dinghy" talk , lest I be cast off and keel-hauled.

Pretty And Practical

Hey, here's an idea that's pretty neat. I read last June about a concept being developed in Scotland, in which roadways would be used as power collection stations, and how heat absorbed throughout the day by the blacktop can be converted to power and stored for later use. I thought that was a promising development, since there are an awful lot of streets soaking up the sun's rays year round. Now there's another cool idea for the "fun things to do with roads" list. A team of Australian engineers has come up with a new way to turn roads into water collection and purification systems. Anna Salleh writes for Science Online that they are developing a new kind of porous paver, designed to take advantage of the fact that so many urban surfaces are roads, driveways and paths--about sixty percent of them. Rather than letting these surfaces shed rainwater runoff into waterways, and taking road pollution with it, the pavers would allow the water to seep through them, filtering it in the process by means of additives, microbes, and granulated activated carbon, and then sending it into underground storage tanks. Such water stores could then be used for irrigation, cleaning and the like. Not bad, eh?

One side effect of this alternate to standard concrete or asphalt is that trees planted nearby would also benefit from access to more water and air. Chalk this one up in the "good side effect" category. Happy trees are always a nice thing. The pavers could facilitate other greenery, as well. The article mentions that the pavers "can be seeded with low maintenance native vegetation." I assume this is in low traffic areas. I get the image in my head of a village somewhere, with these special concrete pavers laid out in pretty patterns and lovely Scotch moss weaving its way throughout as part of the effect. Makes me want to go there--wherever there is. Of course, the added bonus comes when you discover that the road isn't just lovely, it's also supremely functional as well, and provides a goodly share of the town's water. Pretty and practical are such a great combination. Lest you fear that a road doing extra duty as a water-gatherer won't hold up as a road, the pavers are reinforced with a special "bonding material" so they can take the weight from cars and trucks. Pretty, practical and strong--everything you ever wanted in a road, and more.

According to Salleh, a full-scale prototype is about to be built. I think the heat gathering system in Scotland is likely well under way, too. If both of them succeed, the streets of the future will be doing a lot of multitasking. "Roads: they're not just for driving anymore." Now they filter water and run your refrigerator, too!! I suppose the two systems are mutually exclusive. It probably wouldn't be practical to collect both power and water from the same roadway. At least, if they try, it would behoove them to make sure they don't cross the streams. Who knows, though? Maybe those underground water tanks could be filled on the rainy days, and then heated on the sunny ones. People are so inventive; I wouldn't put it past them.
