A much shorter (by a factor of 20), probably slightly anti-H2 but realistic and succinct report by 2 Swiss engineers... http://planetforlife.com/h2/h2swiss.html
It is simply incomprehensible how anyone having read this would even bother to start to investigate H2 as a replacement for petrol/diesel. Is this H2 thing some sort of cosmic scam? Mark Abramowitz - if anyone on the List is in a position to know then you are (sorry to put you on the spot) - could you comment, please? PM me if by the time the US wakes up Sunday morning and this OT post is shot down.
