☀ Solar Energy ☀

☀ Well, since I got my solar-powered aquarium pump, I am very impressed with the possibilities for free, clean and green energy from the sun. Previously, the only solar-electric power I had ever used was in a pocket calculator; and a recent wind-up torch that also had a tiny solar panel. ☀ One day, and not too far away, I hope, building materials for walls, roofs and pavements will include solar electric panel "tiles" and "bricks" that just snap together. It will mean free, clean and green power for all. So very much nicer than sloppy, messy and pollutant fossil fuels. Time, also, to start harvesting wind and wave energy. (Hmm. I see little windmill power generators now available on eBay. They should be fun to try, too.) ☀ And isn't it time that all gymnasiums can have some of that kinetic energy turning back into electricity? If a rat in a treadmill can turn a little electric generator round, then there's no reason why humans working out cannot be allowed to charge, at least, their portable phone and computer batteries from dynamos set up in gymnasia. ☀ ☀ ☀ ☀ ☀
