Reverend, Marmot, K1W1,
You're more than welcome, only remeber that May in Europe (especially in France) is THE month of long weekends-and-no-work.
Besides, as I confirmed we'll be traveling to people that DO believe and ARE interested.
For all engineers you are, you react strangely; since 15 years or more all talk about fuel cells, about the hydrogen revolution.
Everybody agrees, believes and claims to understand, without much visible results on the roads or on the water in any of the continents, notwithstanding the billions (mostly tax payers' money) spent.
It is of course easier to disbelieve a small unit than to challenge major multinationals with questions such as in last replies, right?
From the beginning I did not request your guys to understand, I was simply posting (what I thought to be) an interesting development.
Cheers (as K1W1 says)!
