The Elderly Green Machine: Solar Wheelchair
A group at Southern Taiwan University of Technology have created the world's first solar-powered wheelchair (which may or may not be true). Allegedly the thing runs entirely off solar energy and needs no plugging in. It was designed to be gentler on the environment and prevent people from being stuck out in the rain because their traditional electric battery ran out. So apparently it runs on rain too and not just sun. Because most of the time it's raining out there isn't much sun. What can I say, I'm a keen observer. But you know what there is a lot of when it rains? Worms. That's because when rain mixes with dirt it makes worms. It's a chemical reaction or something.
