Canadian Raymond Wang is developing a roof-mounted system based on piezoelectric technology (converting mechanical stress into electricity) in order to harvest energy from rain, hail, and snow and convert it into useful electricity.

Did I mention that "Weather Harvester" is not a company, but the name of a science fair project?

Oh yes, and did I mentioned that Raymond is 14-years-old?

If you're impressed by Raymond, check out Green Shields, a project to render school buses more energy efficient, and created by another awesome kid, Jonny Cohen (now 16, but 12-years-old when he first had the idea).
