Nanotechnology professor says solar efficiency could double

Solar power could become twice as efficient by employing nanotechnology. That’s according to researchers led by Professor Bengt Svensson at the University of Oslo (UiO), who say by combining two different types of solar cells, much more sunlight can be captured. Around 99% of existing solar cells are made from silicon and only utilise 20% of sunlight, mainly from the red […]

Scientists generate electricity from viruses

Scientists in the USA claim they have found a way to generate electricity from “specially engineered viruses”. The scientists say the viruses convert energy from the tap of the finger into an electric charge. They tested the process with a generator the size of a postage stamp, which produces enough current to operate a small […]
