Designer Dmitriy Shcherbakov plans to power a concept called Greenergy, using an energy source not used before, temperature fluctuations. Greenergy is a music player that also has a heating module and a light built right in.

This is nothing new, Atmos Clocks in 1928 used to use this technology but no one has ever bothered to put a futuristic spin on it and actually put it to complete use. Shcherbakov says he is not sure how much energy his gadget will produce but if it does what it is supposed to, sign me up, I want one. This is could be a great concept if its successfully carried out.
