So the company took the popular Chevy Equinox, gutted its engine, transmission and gas tank, and replaced them with an electric motor derived from the EV1.
Instead of a battery, however, this time it's powered by what's known as a hydrogen fuel cell. In short, if you zap water with electricity, it will break down into hydrogen and oxygen.
About 170 years ago, a German scientist (who may have been reading his notes upside down at the time) realized that if you reversed the process, and could combine hydrogen and oxygen to make water, you'd get electricity as a byproduct, with water vapor the only emission — not that people cared about such things in the middle of the coal-powered Industrial Revolution.
A few years later, a Welshman built a device that could actually do this, using a catalyst to chemically combine the two elements and pump out electricity....
