Let me know how well it works. It appears that the site is in Canada, so
it must be on the up and up!

cn is China. Still think it's on the up and up?

Oh.

Hell yes! That's the country that has the Olympics, right? It's the country
the liberals think wants to be our 'friend', right. The country with no
designs on the USA or any other parts of the world?

Sleep tight. Obama is.

First place, the chassis is a thing of the past. Today there is just a
welded together steel box. There isn't room for any large tanks. Maybe
a bunch of small ones.

My car and many pickup trucks have a chassis, though you are essentially
correct. Too bad...frames are a good thing.

What's the differentiation between a large and a small tank of hydrogen
in this instance?

I have a truck and a Lincoln Navigator and both have frames, but we
were discussing cars, I thought. There are no more cars with separate
frames that I know of.

I would call the usual size the welders use too large. The idea is to
avoid intruding into the passenger volumn too much and still have
reasonable ground clearance and center of gravity. It isn't actually a
show stopper, although enough range might be hard to get. High
pressure cylinders are very heavy for what they hold, and small
diameters are favored from a strength standpoint, while the big ones
that won't fit are possibly more efficient from a weight standpoint.

If you have a lot of hydrogen, the thing to do is use it to
hydrogenate Canadian tar sands so that you can get a reasonable yield
of gasoline or other light products. If you break a ring there are
vacant sites for a hydrogen and I would guess the stuff contains a lot
of rings. Canada has lots of the stuff and they are developing it as
fast as they can.

You can also use it to make hydrocarbon fuels from coal. The US has
enormous ammounts of coal.

After the Hindenburg, you'd think Germans would have learned a lesson....

If the tank ruptures on one of my used vegoil Mercedes diesels, the big
problem will be the FLIES!...(c;

Until someone figures out how to make hydrogen in any efficient manner
this is just a science fair project.

Electrolysis is quite efficient, although the electric power plant
that serves the hydrogen factory is not. The actual efficiency
is about the same as charging a battery, some 90+%.

If you are hydrolysing water you would be better off just using the
electricity directly. Hydrogen is just a battery, storing electrical
energy and not very efficiently.

Maybe. What do fuel cells weigh. Lead batteries are very heavy
and you use substantial ammounts of energy carrying them around.
I suspect that fuel cells would also be heavy but I don't have any
figures.


These hydrogen generators in your car scams assumes there is so much
wasted capacity in your engine/alternator that you can recycle some as
hydrogeny.

Using shaft work from a hydrogen fueled engine to make hydrogen is
ridiculous. If that would work, the thing would manufacture fuel from
nowhere. Perpetual motion machines are known to be impossible.
