As John said, nothing is "free". One approach to the hydrogen problem might be to use hydrogen in a liquid, methanol, for example. This can be produced from green matter which uses photosynthesis , a photochemical reaction which is as "free" as you are likely to get it.However, methanol still requires land, labour, infrastructure and energy to produce it. If on balance it is not economic, then it wont happen. I worked with a company that produced fuel cells for producing energy on small islands where tradionally motor generator sets were used. Fuel cells are actually quite complex devices, and I doubt that the locals would have been able to maintain it, whereas motor generator sets are quite simple, the technology is a hundred years old, and plenty of people can fix them.Despite my comments, I am all for finding alternative energy sources, but I don't have millions to pump into new ideas, the sort of people that do want to make money out of their investment in their lifetime.Cheers,Richard
