Brazilian makes power from a penny worth of paper, graphite paint
SANTA MARIA, Brazil, – A Brazilian researcher has discovered a way to generate enough energy to power a small Christmas tree using about a penny worth of paper and graphite paint, opening a new possibility for cheap, sustainable electricity for poorer communities.
Kelly Moreira, a 22-year-old masters degree student showed off her invention to Reuters by rolling thick black graphite paint onto brown paper, then stacking several sheets together.
