Here's a "Duh" moment from lessons learned in childhood. Do you remember when you were a kid and all the small fry in the neighborhood would run around from house to house all through the hot summer days, usually barefoot? How many times did you eech and ouch your way across the scorching pavement to get to the new hangout of the moment? Why has no one ever thought of saving up all that heat exploding off the blacktop--translation: energy--and using it to provide power for some of the various endeavors of humanity, especially cooling us off when we finally get where we're going? Well, now somebody has. They're even saving the heat up to use in the winter. I just love human ingenuity.
