Carbon levels in the atmosphere are at the highest levels in 3 million years and while politicians debate what to do about it, researchers at Lawrence Berkeley National Laboratory in California are putting forth a potential fuel solution, harnessing a carbon-neutral source of energy: the sun.
Solar energy is not a new concept but the team at the Berkeley Lab have created an artificial forest that captures solar energy, converts it into oxygen and hydrogen, which can then be used to power fuel cells and produce renewable energy. The ‘forest’ is actually nanowire trees which absorbs sunlight and then mimics the natural process of photosynthesis that trees and plants usually perform.
