I have a better alternative.....
The issue of 'green power' is a large one, people finding ever more green ways to get it what with the problem of global warming and the power industry contributing to it.
You can get power via a dynamo attached to a bike, rowing machine, anything.
There is also a large global problem of obeseity especially in children and people are starting to get worried about the health implications......
Merge the problems.......I spy solution
(Sorry, i had to)
