'Electricity out of essentially nothing': Invention creates power from falling snow

from CTV News

Scientists from University of California, Los Angeles and McMaster University have invented a nanogenerator that creates electricity from falling snow. Most Canadians have already seen a mini-version of this, McMaster Prof. Ravi Selvaganapathy told CTV's Your Morning. "We find that we often get shocked in the winter when it's dry when we come in into contact with a conductive surface like a doorknob." The thin device works by harnessing static electricity: positively-charged, falling snow collides with the negatively-charged silicone device, which produces a charge that’s captured by an electrode. more
