I know that it can be difficult to find an outlet when you’re at an airport or bus station and desperately need to charge your cell phone or laptop. This concept is a chair that the user sits in a and rocks back and forth with their power plugged in to the built in power chord in the chair. Instead of taking electricity from the building, that chair actually transfers the energy you’re creating by rocking into the gadget you’re charging. Hey rocking is fun anyway so why not kill two birds with one stone.
