yep, and wind farms
Its getting to teh point that personal wind turbines might become viable for people
heh, I wonder if you could fix up all teh exercise bikes in gyms teh world over to generators so all thet energy is transformed into something useful!
Mmmmm get a couple of home wind turbines, modify the blades to pedals and get teh overweight kids to sit there at night pedalling away to be able to watch TV, Obesity wiped out at a stroke!
