@Jake122206 жыл бұрын
@ completely different aims. The magnetic field like they use in tokamak reactors can handle far higher temperatures (basically unlimited) so the exhaust could be kept far hotter and thus work far better, it would also save on the weight of the cooling system though that depends on how much weight the magnetic system would require.
@avelkm6 жыл бұрын
@@Jake12220 In that case weight would be relatively irrelevant, cause it's fixed weight. With hydrogen cooling you need to have liquid hydrogen as a "fuel", so rocket equation and all that stuff, it's not only weight but also volume and is not easily scalable. With fixed weight of magnetic rig you will easily compansate with higher energy density and higher exhaust speeds of metallic hydrogen.
@Jake122206 жыл бұрын
@@avelkm l agree for the most part, my only concern is how the energy for the magnetic field is being generated. If the power can be generated from the hydrogen or a process already happening then great, but if it needed a large battery type system then the weight would be a concern. On the upside the feild would likely be controllable so could vary the width of the exhaust as needed for even greater efficiency.

Scott, very good and informative video as always, but the device they used is called "Diamond Anvil Cell" (often just called "DAC" in research literature), not just "Diamond Anvil". A DAC does utilise two diamond anvils usually, although there are special ones that have two smaller diamonds on top of the larger anvils. The highest pressures achieved with this technique go up to 770 GPa (as claimed by a team in 2015), which is much more than the ~350 GPa in the Earth's core, and also much higher than the pressure of ~500 GPa that was reached by Dias and Silvera for the metallic hydrogen publication.

Although liquid hydrogen has a very high energy density in terms of energy per unit mass, its energy density in terms of energy per unit volume is TERRIBLE. This problem expands to much more than just the fuel tanks, too: you need larger ducts for moving it, larger turbines to pressurize/move it, etc. You actually ad a LOT more mass to your ship and far more inefficiency just by using such an "efficient" fuel as hydrogen. It looks good on paper, if you only look at its energy content, but in practice it's just not practical.

New materials don't necessarily get cheap, or even that much cheaper. For example, monoisomeric medicine have been known for as long as we have known of medical chemistry and isomeric compounds. Isomeric molecules have identical contents but are different in shape, which makes them extremely hard to separate with traditional chemical processes and requires inefficient and expensive separation methods. However, they're very useful in certain medical needs. Cisplatin is a common and effective chemotherapy drug, but its isomeric counterpart, transplatin, is medically useless. In order for the chemotherapy to work, the cisplatin must be very pure, and producing it is still almost as expensive as it has ever been. Then there are of course unstable substances which will always need specialized equipment to produce and can't effectively be stored for any period of time. For example certain isotopes of Polonium can only be produced in 3 most advanced nuclear physics laboratories in the world, 2 of them in Russia and 1 in USA. Materials like these will always be extremely expensive to acquire in any real quantities.

It seems silly to even consider adding that much complexity to the design since a metallic hydrogen engine would already be so complex, and a metallic hydrogen engine would already be so much more powerful than a liquid oxygen hydrogren rocket. However it occurred to me that the exhaust product of the metallic hydrogen engine is one component of our current most efficient rocket fuel. I guess you'd have to combust the hydrogen and oxygen without decreasing the velocity of the H2 exhaust? It just seemed like an interesting thought experiment, I'd be curious to hear your thoughts.

Serah Wint It's not ferrous, so I would say 'no'. For example, stainless steel (or pennies, or US quarters) won't attract a magnet. Magnetic confinement works with plasma, which is electrically conductive, and highly charged, making it susceptible to magnetic confinement. I don't think long term confinement of plasma has ever been achieved, either. They're hoping to get up to 8 minutes or so of continuous fusion with the biggest experimental reactor being built, which will only possibly lead to commercial viability of a fusion power plant by ~30 years from now. This depends on material science discovery required, and increased confinement pressure, and duration of maintained confinement.

It sounds like the issue is the energy consumption of your magnets. Probably superconductors so you'd need to cryogenically cool them constantly, absorbing all the heat from the propellant. Easiest way to do that is.. a tank of liquid hydrogen that you run through them and allow to boil, then mix with the propellant to cool it further. That's back to what Scott suggested, although it might end up being more efficient.

Could you use a magnetic containment instead of a physical one for the combustion chamber? That might be a work around for the high temperatures instead of cooling it

If you can mass produce Metallic Hydrogen, then i guess you could also make Metallic Oxygen? Would combining those two lower the temperature in the engine?

Metalic hydrogen would behave as a high explosive. Take nitro glycerine for example: it gets a big part of its energy by recombining the diatomic Nitrogen atoms in to N(2) with their super strong triple bonds. Recombining H(2) in solid metalic hydrogen would produce a similar high velocity energy shockwave through the solid and it would "rapidly decompose" - i.e. not combust in any controllable manner. It would make one hell of a super weapon though, without all the drawbacks that come with Nukes.

@krillin68 жыл бұрын
Vladimir Akopyan Everything is some sort of energy storage, really. "Poor man's" is highly subjective. "Different" would be better.
@Teknokraatti8 жыл бұрын
Well, antimatter would be massively more expensive to produce and contain, and release massively more energy per unit of mass. By those standards, the metallic hydrogen would be "poor mans antimatter". It's a bit more sane material for now though, we haven't been able to produce any significant amounts of antimatter, and containing it has obviously been ridiculously hard mission.
@Mernom6 жыл бұрын
Antimatter would be anything but efficient. It would require enormous magnetic fields to store safely, and those take energy to maintain. and even then magenetically neutral particlese can infultrate the contaimentunit.

@jonathanbrown29818 жыл бұрын
Just for clarification, density is the amount of mass per volume, while hardness is a material's ability to resist a physical change in shape (scratching, crushing, cracking) that is related to the strength of atomic bonds. I might be wrong about hardness though.

I keep seeing comments about metallic hydrogen being 1 billion dollars per ounce. Y'all are missing the point, guys. Demonstrate that it's physically possible first, then it just becomes an engineering problem. If we know it's possible, then we can start creating machines and manufacturing techniques to produce it in larger quantities and for less money, and we can figure out how to store it, etc. In fact, I'd wager we could probably get costs down to as little as $10 million per ounce! See? Totally doable

two questions: 1) would it be possible to create this given a strong enough magnetic field? 2)as far as cooling methods what about constructing your combustion chamber based on modern jet engine technology, by this I mean double walled separated by an air gap or in this case use the air gap to pass coolant through and then to a radiator?
