Ultra-light liquid hydrogen tanks promise to make jet fuel obsolete

A revolutionary cryogenic tank design promises to radically boost the range of hydrogen-powered aircraft – to the point where clean, fuel-cell airliners could fly up to four times farther than comparable planes running on today's dirty jet fuel.

Weight is the enemy of all things aerospace – indeed, hydrogen's superior energy storage per weight is what makes it such an attractive alternative to lithium batteries in the aviation world. We've written before about HyPoint's turbo air-cooled fuel cell technology, but its key differentiator in the aviation market is its enormous power density compared with traditional fuel cells. For its high power output, it's extremely lightweight.

Ronn Motor Co. from the great state of Texas has already built a hybrid version known as the Scorpion some years back. Frigette used to sell the hydrogen conversion kits when the Scorpion debuted. Not a bad looking nor performing vehicle.

Yeah, first you burn dirty cheap and available jet fuel, coal or NG or use hydro or other sources of power to make liquid hydrogen, then you burn it in airliners at much less overall efficiency and voila, a cleaner environment!

Can you whackos follow the pea under the shell?

Urban buses and some short haul trucks use CNG quite a lot. MARTA in Atlanta certainly does. Fueling is a big deal, but it’s not too bad to set it up for a bus fleet covering a limited geography

>I was attempting to imagine some sort of catalytic reaction which would initiate the loss of some mass during separation that could be used to drive the reaction forward beyond what the energy inputted would do

You know what we call a loss of mass reaction?

That’s called a nuclear reaction.

The energy produced is described by the well-known equation:

E = mc^2

Some guy named Einstein came up with that.

c is the speed of light, which is a pretty big number, so when you square it, you get a REALLY big number, such that it doesn’t take much mass destroyed to output a boatload of energy. Look up Tsar Bomba for an extreme example.

Sure, but aren’t we talking about making the vehicle light enough to reduce mpg?

I see how this would be effective in an aircraft (brilliant, I think), but the “buoyancy” would impact a car differently because it interacts with the road. Many attributes of a vehicle are designed around the weight.

What if it weighed 100 pounds? Great for aircraft, not for cars.

(Not arguing - please don’t make me do the math!)

I think the idea behind fusion is you can generate more energy than is needed to produce hydrogen and contain the plasma using lasers or magnetic fields. So once they get over those two hurdles we will have a new source of energy.

So far they have not produced enough energy for those two things, but they are getting close.

Oxygen can be bottled for industrial use or to use in medicine.

Oh, I just realized that I was incorrect in my first post and your statement is correct.

Force of friction = normal force * coefficient of friction.

You are correct, coefficient of friction does not change signicantly in this case.

But as normal force is reduced, force of friction reduces proportionally.

A one ton car that “weighs” 100 pounds because it has a balloon in it has mass, but can’t accelerate or decelerate very well.

Now winding up with my last whiskey this evening.

Hydrogen.

“Water and electricity. The electricity can be from any source, but preferably the sun, hydroelectric, or wind.”

how many tens of thousands of windmills and hundreds of square miles of solar panels do you think it would take to make enough hydrogen from water to power the entire U.S. transportation fleet including automobiles, trucks, locomotives and ships? you know, so fossil fuels wouldn’t have to be used?

Yeah I was smoking too much weed today and was pondering a bunch of nonsensical stuff unfortunately. Still I remember as a kid doing the electrolysis of water I was surprised how little energy it seemed to take compared to the volume of the gases produced. Since splitting H2O involves not only a chemical change but also phase change, there would be a transfer of heat energy between the molecules and the surrounding environment, in this case going from the environment into being absorbed by the molecules and exciting them into a gaseous state. So it’s not a closed system, outside energy (heat from the environment) would be introduced into it. Whether enough is gained to make a difference is probably questionable though.

Yeah, I can just imagine the results of a car with a liquid hydrogen tank getting rear-ended.

Hydrogen is not well suited to being in a tank. Petroleum engineers deal with this in their distillation plant designs.

Indeed. There are tons of materials issues that are well known. Metals become brittle, among other things.

Well supposedly, the hydrogen leaks out before anything can happen. The Zepplin only went kaboom because of the sealant they used on the canvas.

Fuel forever, until we run low on water.

Remember, a tank of hydrogen can also be described as a potential bomb.

I believe you've hit upon something there Jonty. /s

Probably WHY after the ATOM Bomb next they came with the HYDROGEN Bomb.

Yes. That is exactly what came to mind! :-)

This link attaches numbers to your musings. The electrolysis of water does indeed absorb a modest amount of energy from the environment in the form of heat, in addition to the electricity required.
