The world's first international fuel-cell-powered go-kart race took place in Rotterdam, the Netherlands, on Saturday. Six teams participated in the "Formula Zero" event, which is aiming to be a zero-emissions alternative to today's high-performance "Formula 1" car races. The six teams used go-karts powered by fuel cells, which electrochemically combine hydrogen with atmospheric oxygen to produce electrical power and an exhaust of pure water, producing zero carbon-dioxide emissions.
