One Comment24 November 2013

copper-nanowire-catalyst-1A group of researchers at the Duke University have managed to devise a novel water splitting system that can produce storable hydrogen fuel. The system uses copper nanowires, fused in a see-through film, which can split water molecules using the power of sunlight. These nanowires offer an efficient and low cost method for solar energy… »

Paper Generators – low-tech and inexpensive way to harvest energy from friction

By Damir Beciri
9 October 2013

paper-generator-1Researchers at Disney Research, Pittsburgh and at Carnegie Mellon University recently presented a simple system that could be used to harvest power of different gestures performed onto a paper surface. Named Paper Generator, the system exploits gestures such as tapping, touching, rubbing or sliding friction in order to run simple interactive applications involving books, posters… »
