Eco power is the new rage for the newest devices be it as a solar charger or wrist strap to power your cell phone, the idea of using human effort & energy to produce power real-time for your own benefit seems overwhelmingly appealing to me. The Revolution Door from Fluxlab is a revolving door that would create energy via generator. Apparently the idea for such a device is old, and the implementation is difficult because weaklings already have enough trouble with revolving doors due to the seal created and their lack of hot, sweaty, rippling muscularity.

However it was designed as more of a conceptual piece to get people thinking. I hope more efforts are made like these to make some power to be generated by our own efforts without spraining something in the process.
