If you open a health club with my idea I want ten percent!
The funny thing is if you go into a health club you will see that the treadmills have something like a two horsepower motor built into it. Thats a lot of juice. It does not make any sence to me. It should have about a 1/4 hp motor instead that offers resistance instead and feeds back into the grid.I do not know how the bicycle trainers work. Let's see 50 people in a gym x 100wh/hr (is that correct Rien? >>grin<<)= 5 kilowatt-hours/hour x 10 hours/day = 50kwhr/day x $.12/kwhr = a whole $6.00/day. Bot over the whole country maybe we can shut down a nuclear power plant or two!! But the savings on NOT using the electricity would be quite a few times GREATER than the actual production.
