Windy out there! PV = nRT right? Does this constitute an understanding? Whatever. I got paid thirty bucks yesterday evening to have a workout, at least that is how I choose to see it. How much energy could we generate if we hooked all the treadmills, step machines, stationary bikes, glide trainers, rowing machines, and hamster wheels in North America up to the power grid? Rather than calories burned people could proudly proclaim how many kilowatt hours they contributed. Gyms would just set it up to offset their hydro bill. Skepticism of human nature kills hope and is in itself a self fulfilling prophecy of negativity. How about the harder you workout the lower your monthly fee? I gots to go to work!
