both with the latter being the most likely. I think though that the
bio fuels will probably outdo the Hydrogen overall in the big

I think a lot of the hydrogen advocates are missing the massive change
to infrastructure needed - we would need:

- new cars

Average turnover is five years.

Maybe, but those 5-year-old cars aren't junked, they're bought and
driven for another 5 years by less wealthy people.

Yes...so? The point is for the majority of vehicles, not a complete purging
of the inventory.



- new filling stations

Like when we went to unleaded from Regular and "Hi Test"?

No; hydrogen gas takes very different handling than gasoline, whereas
leaded gas could go through the same pumps just fine (we decided to
make them change the nozzles to prevent mistakes that would ruin the
catalytic converters).

Wanna guess how many filling stations add that capability (especially when
it becomes pretty much mandatory) versus how many are built from scratch?


- new transport
- new ways of storage (I'm sure keeping hydrogen as a cryogenic liquid
is just not gonna work for everyday cars and trucks)

Like when we went from coal to whale oil to petro-based oils...?

I don't think whale oil replaced coal for much of anything.

Wow! Trivia pursuit champion.

Now try "Innovation Therapy".

Oh, hell...keep your high gas prices and stunted economies heading for the
trash bin...
