The main reason there isn’t much beryllium production isn’t because it is rare or because it is hard to extract, it is because there isn’t much demand for it. There are a lot of mines which have to design their processes carefully so they don’t have to go through extra steps to get beryllium out of their products. If there was a market for it it would be worth reducing the beryllium and extracting it.

yes but thats NOT pure beryllium ! Even the rare earth is abundant but separating one element from another say...praseodyum from neodyum is such a COLOSAL challenge . Making it economically is just impossible Beryllium being hard to purify dooms any ECONOMICAL calculus just like the ''rare earths'' do or just like extracting and handling titanium does But the titanium is a bad example because its an order of magnitude easier to work with. Altho requires impressive machineries and expensive processes titanium is still DOABLE

@@lucasng4712 not necessarily no. while from an energy efficiency perspective it would be impossible to outperform free heat generation since that's quite literally infinite energy. Efficiency is not the only metric used in an economic analysis, nor is it the most important. Utilizing heat energy through steam engines has a limiting factor of space, so while the efficiency would be unparalleled, its actual energy output is limited by how large we can build the generator which in turn limits the projects economically in the form of material costs and land costs. And one could argue that "Performance" would more so refer to Energy Output than the efficiency of achieving said output, hence why you can have High Performance but Low efficiency systems or vice versa. Finding conversion mechanisms that aren't space constricted, so direct heat to electricity conversion (peltier effect), using the magnetic forces to run a generator etc etc, may not be as efficient, but you can scale it further due to not being space constrained. Edit: A really easy way to visualize this, is just comparing the size of a tokamak to the helion reactor, the helion is small enough to be inside a building, the tokamak effectively IS a building.

Its important to recognise tokamaks like JET don't represent a purely energy output, profit driven project. Controlled fusion is one of, if not the most complicated and technically challenging endeavours ever undertaken. As described in the video, nearly every part of modern science and technology needed to advance before any of this was feasible. JET, LHC etc. are publicly funded research projects. They publish huge amounts of cutting edge papers that advance humanity. A big part of that is around superconductors and magnet. From early manufacture where the exact composition of material and its processing affects the final magnetic field, to the extreme complexity of real world performance and the electronics and software required to fully understand and manipulate the field. What this company seems to have achieved so far is incredible, but it is only on the back of publicly funded research where our insights and advancements have been shared across the world. They are the reason that you can now buy relatively "cheap" superconductor setups with well understood uniform fields that originally cost CERN hundreds of millions in grants. I truly love what they have achieved, but the fact this video represents the first time they are sharing it with the world is terribly sad. They are building on the backs of giants and I don't mean Maxwell but their contemporaries in publicly funded science. Fusion and other energy solutions should have had trillions of investment, it is sad that we are relying on a private company who benefits from public research instead of humanity properly funding it for reasons beyond profit. With all that said, I have huge respect for everyone involved in Helions research and engineering. If realised, controlled fusion represents perhaps the single most important technology ever developed. If humanity has politically failed to fund energy research, then it is better that entrepreneurs take the risk and move us forward for profit if it ends coal power.

This means that you could use this reaction to power rocket engines and don't have to worry about radioactive and irradiating exhaust. You are right to be a little skeptical because I kept reading how D-T fusion (what ITER and the National Ignition facility are doing) is our best bet. Meanwhile, D-D fusion and He-3 fusion would require much, much higher temperatures to achieve ignition. But maybe this method of smashing things together (something that humanity is good at already) can achieve those reactions. And it does seem this would happen in pulses while tokamaks would generate energy continuously. Still, if going a step closer to achieving fusion means doing things other than tokamaks and laser-based inertial confined methods, this would be a good thing.

Just put an exhaust hole in it somewhere and it could probably become quite the engine.

[@hatman4818]

You could even use the same EM accelerators to fire the exhaust out one end. Part of the problem is you'd need one closed system reactor to provide the electricity to run the second reactor as a propulsor. I think part of the way they want to extract electricity is in discharging the charged plasma, but you would need to keep it charged if you want to magnetically accelerate the exhaust to some insane exhaust velocity. So that would basically require two reactors per engine. But, you could maybe then run it in two different modes. One mode would be fully charged exhaust from one reactor, for maximum efficiency, but low thrust. A high thrust but low efficiency method could be to magnetically accelerate the charged exhaust from one reactor, through the hot inert gaseous products of the second reactor, injected into the stream through a regular engine bell. This would slow the charged exhaust down probably, reducing efficiency, but increase the exhaust mass, and therefore, thrust. So you could make a hybrid engine out of two of these reactors, with a low thrust high efficiency mode, and a high thrust low efficiency mode. Even the "low efficiency" mode would probably have an ISP rating in the thousands at least, making it better than any chemical rocket by far.

@@bestdjaf7499 not saying that what you are saying isn't true but, you'd think they would ask for money if they are broke. can't see any go-found-me links on their website or this video. also its still a private company. if they were really desperate for money they could go public in the hopes that it would generate capital. now would be a good time to do that since everyone is so hyped up. their job vacancy is enormous. maybe they are trying to recruit new people for their project. but who knows maybe you're right and they aren't interested in common-folk their money but are looking to reach out to big investment firms after hyping everyone up.

Helion is going all out on marketing now after the inertial fusion experiment had the enormous success. I see helion everywhere from youtubers to instagram influencers. I think they are in need for some additional funding soon.

[@michaelchomiczewski7937]

Timing is probably not coincidental...

Helion is fully funded all the way to commercialization, actually. What they need right now is qualified employees. AND, these videos were all made before the NIF announcement.

[@MVHiltunen]

Inertial confinement fusion of the NIF sort has no chance as an energy production method. It is not funded or developed with energy production in mind, but for doing nuclear weapons simulation, for which it is rather good.

@@johndawson6057 Yo, what I said.

[@256shadesofgrey]

A few things that I missed in this video: 1. Did they achieve ignition? Or in other words, did they manage to generate more energy from the fusion than they put in to achieve that fusion? 2. What is the pressure at which this operates? One of the issues with tokmaks is that they have to operate at low pressures, otherwise the gas pressure will overwhelm the magnets, which forces them to work at extremely high temperatures. Is it an issue here? Why or why not? And if they do manage to have significantly higher pressure, does it significantly affect the temperature at which this fusion reaction takes place? 3. If they did achieve ignition, how far away are they from generating enough energy to reach a breaking even point considering all of the inefficiencies of the system?

[@timothynoonan8591]

They didn't achieve ignition. Ignition was achieved for the first time in history by a different lab after this footage was taken.

[@256shadesofgrey]

@@timothynoonan8591 Do you know how far off they are? Will their 7th gen reactor that they talk about get close to being able to do it?

[@Zacharysharkhazard]

Ignition is simply creating a fusion reaction; the term you’re looking for is energy net gain within a fusion reactor.

[@ThatHungryAfricanChild]

@@timothynoonan8591 ignition wasn't actually achieved. They lost A LOT more energy than they made to produce the experiment. The laser beam had 2mj energy to create 3mj but in reality they used 300mj to create the laser

by not using water it wasted all the neutrons. Water absorb neutron, just use water to absorb the neutron rays from the fusion reaction, to boil it, nothing else is as simple as this.

[@SephirothRyu]

@@xponen Perhaps if/when they split the reactor design into a generator and a breeder variant (the breeder being used to generate the Helium-3 they want and being the one that generates neutrons) they can use that for partial energy recovery to make the breeder more efficient.

This is one of the more interesting approaches to fusion IMO. Tokamaks are a dead end, as they might make fusion, but getting the power generated to the grid is another thing entirely.

[@robinpage2730]

Tokomak is too small. The tight circular curve pinches the magnetic fields weakening the outside and allowing ions to escape, bleeding energy from a system that cannot afford to lose any energy. If it was as big as the CERN particle accelerator, the curve would be so long, and therefore so low, the magnetic fields wouldn't notice. It would be as smooth as an infinitely long tube.

[@SephirothRyu]

Agreed. They are just too big IMO. About the only way I see them working is if they use helium-3 generated using hourglass reactors like this instead of that DT that needs a huge bery lining and literal steam turbines to extract power.

[@acbthr3840]

@@robinpage2730 ITER solves that with a big magnet in the central void. Theres an alternative design called a stellerator that also makes this a non issue.

[@robinpage2730]

@@acbthr3840 except the problem hasn't been solved or fusion would be a reality by now. Making the circular path longer, and the curvature less pronounced, might have made it a non-issue in the first place. I'm thinking something the size of the Super Proton Synchrotron at CERN. On a side note, the reason the Stellarator was originally attractive was because the plasma interaction with the confinement field induced current in the coils, resulting in a self-exciting system, allowing direct energy conversion without a steam plant; a nuclear plasma electric generator, aka a magnetohydrodynamic generator. Tokomaks can't do that but they were cheaper at the time and steam was potentially more energy efficient than MHG anyway, so Stellarators feel out of favor.

[@acbthr3840]

@@robinpage2730 What? The issue with the velocity differential and magnetic field line weirdness between the inside and outside of the ring in a tokamak isnt the primary barrier to getting the yield up. It helps, but is far from a limiting factor RN, especially since its a negligible problem with the fixes we have. The current limiting factor is actually getting energy into the plasma so it fuses before it expands too much. And uh... no thats not why the stellarator was originally pursed. It was attractive specifically because the design largely cancels out the typical particle drift and helps with diffuusion problems you get in a normal tokamak. It is literally just a normal tokamak, but with a more efficient configuuration since you dont need the core void electromagnet

[@aidencraigallman1656]

Love David's honesty and openness in explaining the functions of the Trenton and I truly believe Helion has the most feasible design out of any of the fusion machines, the physics look and sound solid and the fuel used within their machine seem the most plausible. Thank you for the video

[@sjsomething4936]

As a layman watching the various competing designs etc., I’d have to agree with you. The caveat being that the actual science and engineering are miles beyond my full understanding, which is why I watch videos such as these 🙂. Because I do believe that one day this motley collection of primates will actually harness the power of the stars themselves. And if they’re really lucky, they’ll do so in time to prevent catastrophic and irreversible damage to their home world. ☮️

[@michaelcombrink8165]

Would be cool to connect multiple reactors together to each other the next ones ignition, similar to cylinders in an engine Also it seems like if these guys had half the support and cooperation as the other big reactors, then they could save tons on capacity banks Eg if they could get access to larger grid energy, maybe they could shrink their facility a few magnitudes Eg skip capacitor storage, get crazy high voltage drastically reduce amp load Don't need to step down until you're closer to the machine
