Thanks for the link & update. I just love to see new & hopeful things being tried.
My friend is giving a lot of talks on the hydrogen cell technology. He says it's quite workable, technically; the problems are from the social & economic effects that will be caused in building a new supportive infrastructure (repair-shops, gasoline/petrol stations,etc.)and leaving behind the existing one, which supports so many people now.
He also told me the Univ at Warwick is highly involved - I went to their website but couldn't find anything there. Does anyone here know about that aspect of it?
