It is now possible to produce energy from nothing!

Can you imagine a device that produces electricity from nothing, 24 hours a day, 7 days a week? Electrical engineer Jun Yao and microbiologist Derek Lovley, both of the University of Massachusets Amherst (USA), have created a device called 'Air-gen' or air-powered generator that uses a natural protein to generate electricity from just the humidity of the air. This air generator connects electrodes to the protein nanowires (just 7 microns thick, one-tenth of a human hair), generating electric c…
