This may come as shock to you, but you are wasting energy. Everyday. How about giving back, simply by plugging into your wall? It may come sooner than you think. Nearly every room in our home has an electrical outlet. What if each one had a matching electrical “inlet” so you could give some back?

The idea is that adapter kits would be made available to convert common household products into energy-generating devices. Things like exercise equipment, for instance. Maybe even the wheel in your hamster’s cage.

With a system like this one, you could have all kinds of devices generating power and if you can give some of that energy back, you’ll be saving money.
