Generating electricity via sport in Japan

Japan has a constant power shortage problem since 3.11.

Generating electricity via sport has never been a new idea, albeit often ignored. Witnessing the nuke prob in Japan the time to start may be now.

The power generated can be used to recharge the car batteries whose sales should go to those affected by the earthquake.

One idea is to start with the huge sport gym operators. Sport gym equipped by these machines to generate energy may not be useful if the gym goers do not use. The other is to start with the prisons all over Japan. One of the limited ways to oblige people to do something( potentially they hate doing ) is a way of punishment. The energy to support the prisoners come from the tax payers' blood and sweat. Why do not use the energy to support the people who need help?

You might as well work out to keep healthy and make people happy/make at least unhappy people less unhappy rather than just to lose weights.

Pretty inefficient but just an idea.
