Wheels.

I know.

But you didn't say anything about having tanks, in your original post?

Thus that's the reason for my "Hindenburg" post!!

Alkthough her hydrogen may have ignited, the Hindenburg went down with her envelope burning. I belive that the skin was what caused the catastrophic failure, not the H.

You're half right GORD.

Yes the skin burned away. Thus releasing what hydrogen that didn't burn.

The other half burned in the fire.

Can someone tell me, why is Hydrogen more dangerouse than any other flamable gas.
It is not. That perception comes from the Hindenburg explosion and people worried about hydrogen being released in a car crash.

If you rupture the container, the hydrogen will spray out of the tank and disperse through the area before it floats off. This is different from something like diesel that will tend to just pour on the ground. It is not at all different from propane.

There is little point in trying to decompose water into hydrogen and oxygen to burn it in your boat engine. The energy you can extract by burning the hydrogen will always be less than the energy you used to extract the hydrogen.

This is true whether you burn the hydrogen in an internal combustion engine or a fuel cell.

That is why so much research is being done on diesel reformers (see my earlier post)

I cant go into details about why I was looking at this area, but there is a reasonable expectation that within about 10 years, an electric fuel cell driven boat/car using hydrogen derived through a diesel reformer will be a viable system. There is a decent 75 hp electric drive already available, and the weight reductions due to having a fuel cell system rather than ICE will mean that performance will be compatible with abt 100hp car of today.
