Re: Hydrogen Power
So is natural gas but that is used a lot.
Even if you are using tradition power stations, at least some of that is going to be renewable/nuclear so not producing any pollution. So it would still lead to at least some reduction.
We will be needing hydrogen stores anyway for fusion (experimental plants have been built) in which case you will get a lot more energy out. You would be getting the hydrogen electrochemical means. Fuel cells use the same way so lose useful energy through inefficiency. Whereas fusion uses nuclear energy converting actually mass into energy. Fusion is still a while off but not so much of a Sci Fi thing as most people think.
Oh and I've actually seen cold fusion going on, no really. Unfortunately it involved putting more energy in than out - if anyone wants it explaining I can. It was done as a curiosity using a particle accelerator - fun to have seen though.
