CARS that run on hydrogen-powered fuel cells are squeaky-clean dream
machines. The trouble is, the only way to make hydrogen at the moment is to
split water with electrical energy from polluting power stations. Now a team in
Japan has found a new way of doing the job: use a satellite to convert solar
energy into a powerful laser beam that’s capable of busting the water
molecule.
Japan’s National Space Development Agency (NASDA) and the Institute for Laser
Technology (ILT) in Tokyo have joined forces to test out the feasibility of a
space-based laser. Outlandish as it sounds, they have…
