63% of Americans are struggling with obesity (http://www.americansportsdata.com/obesitystats.asp). There is also a large green movement going on. So what if we combine these two ideas? I have been looking at instructables on how to build your own wind turbine, and instructables on how to use your bike as a generator for charging ipods and cellphones... why not combine the two ideas and create a stationary bike that puts electricity back into the power grid, much the way a home turbine does? Granted... it wouldn't be much power, but the more you exercise, the more money you save--and the better shape you get in. And those pennies each month add up to dollars each year... and again... the health benefits. It's almost like getting paid to exercise, which can be a big motivating factor. Thoughts?
