hydrogen is also hard to store savely as, believe it or not, the molecules are very small and thus can leak where other gases wouldn't.
Of course it is highly combustable and hard to detect when it does leak. Of course all such ideas need to be thoroughly developed hot and heavy, but predicting now which ones will really work out is anybody's guess. Can you all believe the automobile milage standards havn't been updated for over 30 years and they're just now getting round to it? Absolutely rediculous. Tom
