Sounds like this guy has built a system that uses solar power to run his home and on days when the solar energy availible exceeds his useage, it's creating hydrogen by electrolosis. That hydrogen is used to power his car and a generator for cloudy days.
Sounds pretty smart, although it's a very expensive system. I've always said that the problem with hydrogen is that you have to use a lot of electricity to make it. Using solar for that process makes it much better for the environment, even if it is less efficient.
Thought everyone?
