FYI: What Happens if I Put Rocket Fuel in My Gas Tank?

They already have one; it's called the Hydrogen-7 and it's made by BMW. Do your research. =.=

@corvo
the Hydrogen-7 runs on hydrogen gas not liquid hydrogen (rocket fuel)

see me, find me.

Add on to Tom's Comment: Corvo, you should of done your research more better, not stop at the first paragraph and then go off thinking you know more than anyone else here.

Actually you didn't even answer your question right. Your question was "what happens if I put rocket fuel in my gas tank?".

If you put liquid hydrogen in your car gas tank it would immediately begin volatilizing at the assumed room temperature of your car, and burst the gas tank and explode in all probability. After all it's just liquid hydrogen and contact with the uninsulated tank would cause it to warm rapidly, gasify, and quickly surmount the capability of a tank not intended for high pressures to hold the gases inside.

So that answer to your question is it would be a total disaster if you persisted in trying to fill the tank with liquified hydrogen.

So in affect this is a really stupid question. You would blow yourself to bits if you tried.

@ Gizmowiz Fuel tanks are vented, not sealed units. They vent at the fuel cap and they have a separate vent line. Im not saying that the tank wont explode but it wouldn't be as easy to explode as a sealed tank would be.

But the real question on everyones minds is how will your car react to hydrazine. I postulate that if a running engine where switched to hydrazine you could run the car with no air, the hydrazine would spontaneously decompose when it hits the hot cylinder. This will make driving your car underwater drastically more easy.

Corvo is right. The BMW Hydrogen 7 runs on liquid hydrogen. The hydrogen fuel is stored in a large bi-layered, highly insulated tank at cryogenic temperatures. BMW says the liquid hydrogen offers 75% more energy per volume than if they would use compressed gas (at 700 bars of pressure). The hydrogen tank’s insulation is under high vacuum in order to keep heat transfer to the hydrogen to a bare minimum.

When in hydrogen mode, it injects the hydrogen directly into the car’s air intake manifold to be combusted in the engine’s cylinders rather than converting the hydrogen’s energy into electricity to operate electric motors like a fuel cell. BMW has solved the problem of the hydrogen damaging the engine because of cryogenic temperatures. The car can also switch between hydrogen and gasoline at the touch of a button on the steering wheel. Read more of it on wiki or the BMW website. There are also some video's on the web.

The pressurization rate from dumping liquid gas into the tank would far exceed the vent's capability to vent the gases. So the tank would burst.

Besides that, while your filling the tank, you would be using a non-vented filler line to pour the liquid into the tank and that would prevent the gases from escaping-until you removed the line and the pressurization would have pure hydrogen gas venting at extreme pressures. No way you could recap it.

You simply cannot fill a regular tank in any way or fashion that would avoid a very unsafe condition and probable explosion.

Want to call MYTHBUSTERS and schedule a test?

it is a hypothetical question, they are just pondering whether liquid hydrogen could be used as a fuel for an automobiles, BMW does this as the "BMW Hydrogen 7 runs on liquid hydrogen" as Greenmatrix states, take a quaalude gizmowiz and chill, negative cheers

Just as a quick notes, using a special rig, the Mythbusters have confirms that you can run a car engine on hydrogen. But I believe they were using a normal cylinder of compressed gas, not liquid hydrogen.

Thanks Chuck. It`s funny how some people just make up their own claims and ignore facts. Perhaps we should see it as sad with all the information being freely available at the official sources. Not to mention all the engineers building this liquid hydrogen BMW and then having some people say it`s a hoax. But of course it`s nothing new with many still claiming the moon landing and evolution as a hoax. Ignorance must be bliss.

no problemo, cheers

You mean evolution is not a hoax? Gee, who knew.

There are conversion kits that either convert a diesel engine into a natural gas engine, or more interestingly, allows the engine to run in a hybrid mode where it starts with diesel but natural gas is injected at higher loads or speeds. I mention this because the methane in natural gas is as close to being hydrogen as it can be and still be a hydrocarbon. Also natural gas is apparently going to be the dominant fuel in the future.

this is definatly a myth that NEEDS to be tested!!
