[@noslo1098]

Social engineering has a great success ratio. Overall, short-term results defy logic - and the effectivity of resolve or all-in investment makes the audience captive, invested, and engaged. Unfortunately, true engineering relies upon math (best guess theories applied through observation with a numerical result), physics (observing the interactions or inherent action of things no one understands and applying or suggesting new numerical results) and applying said theories with results. Engineers bridge the gap between theory and reality. They don't theorize, they do.

I really enjoyed the documentary. I retired from Helion in July of 2021, now I can show my family what I did for a living. I worked on FRC plasma machines for 35 years altogether. It’s good to see all the hard work come to fruition at Helion. My one disappointment with the footage is you didn’t show much of the puff fill system. That was my big contribution.

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.

The nuclear waste produced by Tokamak reactors are negligible when compared to our current nuclear power waste. It's barely a minor inconvenience. That's the reason why they refer to fusion power as "clean" energy because while it does produce some nuclear waste, the amounts are tiny and easily manageable.

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.

Yeah, because if they really could achieve this, they would have achieved aneutronic fusion. 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.

Here are some problems that's not mentioned in this video. 1 D-He3 is much less reactive than D-T, depending on the temperature it can be anywahere between 10 to 1000 of times less reactive than D-T which means less fusion for the same input energy. 2 The D-He3 mix will sometimes fuse D-D into He3 + N so they still have to deal with neutron radiation like all other reactors. 3 Another problem is something called Bremsstrahlung which will radiate away alot of energy that won't be captured by their electric field.

[@charliem6590]

I want to start by saying that I'm not at all sure that Helion is going to succeed, but I hope they can. Fusion energy generation is at present a field with a lot of players, with some luck at least one of them will get there. Regarding your specific points, let me see if I can argue why those problems could be overcome (not they are going to, just that we cannot say it will be impossible, not yet): 1. Yes, a D-3He mix is less reactive than a D-T at the same ion temperature but that's not a problem per se, the question is whether a D-3He mix reactivity is high enough. If I can propose a simile to try clarify this, gasoline combustion is quite less energetic, gram to gram, than hydrogen combustion but we don't fuel our cars with hydrogen, this is because gasoline is good enough, and because hydrogen has other problems. Helion says they think D-3He will be good enough. We'll see. 2. Again, yes, a D-3He mix still produces neutrons. My thoughts about this. 1) Neutrons produced in D-D fusion events are much less energetic (2.5 MeV) than from D-T (14 MeV), and much less than neutrons produced in fission reactors. Also, 2.5 MeV is well under the average activation energy of most structural materials (stainless steel AAE is 20MeV). 2) The neutron production can be reduced changing the D-3He mix ratio without compromising energy production too much (Helion speaks of using a 1to10 Dto3He mix). 3) The selection of structural materials can also help, not all materials produce long lived isotopes when bombarded with neutrons, Helion says they know how to build the machine mostly with materials that only produce short lived radioactive isotopes (for example, Aluminum isotopes produced by neutron bombardment decay in minutes, not years). As before, we'll have to wait. 3. Bremsstrahlung is produced by electrons and it is heavily dependent on their temperature. The plasmas in Helion machines are not in thermal equilibrium, nor they want them to be, and in particular they've measured a big temperature gap between ions and electrons. Electrons are far cooler, ergo, less Bremsstrahlung. Low enough to not robe the plasma bulk of too much energy ? I don't know, and neither does any of the critics. Summing up, Helion has still to prove their concept but saying, as the Improbable Matter video says, that it is a scam is in my opinion jumping the gun.

[@peterjohansson1828]

@@charliem6590 Those are some good points and i do hope they solve these problems but to me it seems almost inevitable they'll really struggle with atleast one of these problems. If they decide to try runnging a cooler reactor then the bad reactivity of D-He3 becomes worse much quicker than D-T making it really hard to achieve a high enough Q total value to justify a commercial reactor. If they try a different D-He3 ratio to try to increase Q total then neutron radiation is going to be a big problem they'll have to deal with like all other reactors. If they increase temperature to increase Q total then they have to solve large number of engineering problems aswell as dealing with bremsstrahlung. While i do want them to succeed, it's really hard to not be skeptical when the rest of the world struggle to get above Q plasma 1 let alone a Q total of 1. Let's not forget they'll need much more than a Q total of 1 in a commercial reactor.

[@charliem6590]

​@@peterjohansson1828 Well, inevitable is a big word. It may be that one of those problems (or any other yet to be discovered) end up being a show stopper for Helion, but I'm hopeful. About your point over running a cooler plasma, from what I've read from different sources Helion intends to (in their next machine, Polaris) at least double the temperature, mainly to improve reactivity (in the last one they reached ~100 million Kelvin). With D-T the ideal temperature for a steady-state machine like a tokamak has been calculated to be around 135 MK. Above that, bremsstrahlung and other loss mechanisms eat any further gain in reactivity. Having said that, in a steady-state machine ions and electrons tend to thermal equilibrium, but that's not applicable to Helion's machines. According the results from Trenta (the last one), they've measured electron temperatures far lower than the ion temp, up to 8 times if I recall correctly. If we scale that up to a 250MK plasma, it would mean ions at ~250 MK, and electrons at ~31 MK. Ergo, quite less bremsstrahlung than in a tokamak at half that plasma temperature. Regarding the D-3He ratio, they said they've already tried it. Making a 3He rich mix has the consequence of making less probable a D-D fusion event, reducing neutron production, without affecting D-3He reaction rate too much. In a presentation they did for the USNRC last year they claimed that their projection for a 50 MW machine is that it will output less than a 5% of the energy in the form or neutrons at 2.45 MeV. They plan to have shielding outside the main reaction chamber, but it will be reached by only one sixth of that. 0.4 MW in neutrons is something to take care of, but far from intractable. And yes, increasing the temperature might reveal new engineering challenges ... or maybe not. Again, we don't know, but we will ... and without having to risk any of our money.😋

[@Smo1k]

If the neutrons' energy isn't high enough to fuse with anything, I don't see a real problem: Free neutrons have a half-life of some 10-15min (longer time for higher kinetic energy). So long as you don't just vent the reaction product into the atmosphere, that is...

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.

Oddly enough, a gasoline engine came to mind. A fusion reactor that generated power as conveniently and directly as an engine would be amazing, and that's basically what they're doing here, except electronically instead of mechanically. Which is mind blowing.

[@JPEight]

Turbines do have some major advantages over this though, they smooth out the electricity generation as the turbines act as flywheels. There’s so much energy stored in them that if the power station stops, the electricity keeps flowing for a couple of minutes. That buffer also makes it easy to ramp the up or down the power output in response to demand.

TL;DR We have 410,000 years of fuel for 10,000 fusion plants (22.7 times the number of nuclear plants we have), and that's assuming *horrendous* efficiency every step of the way. We are in no danger of running out of deuterium fuel. Long form answer Remember when early on in the video (10:15), it was noted that tokamak reactors would use around 300g of tritium per day? let's say that helion's reactors will use around 100x that per day in deuterium. So, 30kg (30,000g) of deuterium per day means, in the worst case, 150kg (150,000g) of heavy water per day. (30,000g = 7,500mol of D2 with GFM 4, 7,500 mol of D2O = 150,000g with GFM 20) The world is estimated to have around 1.35 * 10^18 metric tons[1] of water. This will contain 1.5 * 10^17 metric tons of hydrogen (again, just GFM calculations). Of this, 0.030% by weight [2] will be deuterium, so 4.5 * 10^15 metric tons. As heavy water, that's 2.25 * 10^16 metric tons (more GFM calc). As we said earlier, 150kg of heavy water per day as an extremely, frankly unrealistically high estimate. That means 54,750kg or 54.75 metric tons of heavy water per year out of the world's supply. We have 2.25 * 10^16 metric tons. That's 4.109589 * 10^14 years of fuel for one reactor. Even if we were to horrendously lowball and assume we can only extract 0.001% of this, that's still 4,109,589,041 years. Assuming we run maybe, 10,000 of these reactors globally (~22.7 times more than the number of total nuclear plants worldwide[3]), that's still 410,958.9 years of fuel. And, personally, I feel that 410 thousand years is long enough to get some off-world fuel going, right?

Now you just need a second reactor, "some initial energy", to start both. and then the electricity output from one of the reactors will directly feed the other (without passing through the capacitor bank).

[@elmarmoelzer2229]

They need the capacitors to also store the fusion energy. Since their machines pulse at somewhere between 1 and 10 Hz. From there it goes into an inverter and then to the grid. That said... They CAN and might (if the site wants/allows it) pair multiple machines that use the same power supply.

For now, it's great there's so much research being done on subject of fusion. We are in much need for cleaner power generation. And I do hope they have enough funding to keep working on this.

[@lkslokinhow]

I was searching for someone commenting exactly that. I'm skeptical about that. Sure, I hope it is all true and they are advancing fast. But a new almost miraculous fusion reactor shows up days after that announcement of achieving ignition. I don't know..

[@jasonreed7522]

As an electrical engineer i will tell you what i think the questions to ask are. We know the conventional thermodynamic power cycle limits steam turbine electric generation to 33% efficiency, so what is the efficiency of this design from primary energy (fusion output potential) to AC electricity (usable energy to the existing grid)? We know a tokamak that is just a fancy water boiler will have to throw out around 66% of its energy, thats just the thermodynamic power cycle when operating at temperatures we can feasibly achieve, no way around it. But this direct capture generator doesn't have that limit, so what is its theoretical max efficiency and actual real world efficiency to compare to the known efficiency of the tokamak? My other question is that this thing is making pulses, its like a 1 cylinder engine, those are some big spikes that need to be captured and smoothed out into something that can then be more easily converted into either AC power or directly to HVDC for long distance transmission (and then get converted back to AC). So what are the parameters of the waveform of these pulses, and how hard is it to capture the energy contained in them and then rerelease is as a smooth AC waveform ready to be connected to the grid and supply baseload power? I'm not as concerned with how they actually are trying to get fusion to happen, thats hard so we try different ways to cheat they system and eventually one will actually be pretty good at it.

@@lkslokinhow Whenever there's an event like this where they developed something in secrecy and then it's revolutionary it starts screaming to me they need more funding which might be well justified but with all those revolutionary products we've seen advertised few if any came to be. So am skeptical but hopeful.

[@MladenMijatov]

@@jasonreed7522 All valid questions. One of the issues I thought about was exactly capturing energy and producing a useful power that can be hooked up to the grid. Am additionally interested in their cooling, which they didn't mention at all and with all fusion reactors this is where majority of energy is going towards. We'll see. Perhaps other videos explain all of that.

[@nick_0]

Yes it is very valid to be skeptical, especially in todays world. But fusion energy and helion’s methods theoretically do have their said potential, it’s crazy. Ofc actually engineering this is a challenge and commercializing it etc. The question of viable fusion is there, but the science is checking out

[@jimmysjamin1]

I have absolutely no idea how these things work, but I sure love watching these videos .

[@janneaalto3956]

I hope it works and does revolutionize the energy section. Just can't help feeling cynical.

[@brandonthesteele]

Yeah there's a very strong leash on enthusiasm here, no one wants to be taken for the "fusion power is here" ride, knowing that we have been on that ride for the last several decades. Brian said fusion may be "around the corner", given its history I would caution that it may be a long time before that corner's turned.

[@sassa82]

Helion has been criticized for its finances, promises and its "voodoo fusion". Daniel L. Jassby, Princeton Plasma Physics Lab, American Physical Society Forum on Physics and Society April 2019 Newsletter, pp 13-16. And SLATE Article: THE Theranos Trial Shows Why We Should Be Suspicious of Nuclear Fusion.

[@5133937]

Fusion is already here, it’s being done with tokamaks, stellarators, lasers, and Helion’s design, among others. The only remaining problem is extracting more energy from the process than it consumes. The more we experiment with different approaches, the more we learn, and net positive energy is only a matter of time.

[@Krill_all_health_insuranceCEOs]

I'm sure in time we'll get it all figured out. 100 years ago no one knew what a computer was. Can you imagine what we might have 100 years from now?

[@aexetanius]

If all of humanity were as cynical as you, then we'd still be using candles and oil lamps to light our homes. We wouldn't have made any progress or advancements in science or technology because we'd all be too busy being cynical about everything. So, thanks for your cynicism, but I hope it works and does revolutionize the energy sector because I have more faith in humanity's ability to make positive change than you seem to.

[@hobog]

Tremendous work animating the new concepts!

[@coopersly38]

Just an animation though

[@jeremytee9960]

The coincidence of this video w/ Simone Giertz's recent nuclear fusion video collab w/ Helion really is giving Helion a lot of great coverage for everyday people online. Really thankful for channels like these that provide such great-quality content that is current and truly cutting-edge.

[@rainbowevil]

Makes me more sceptical of Helion tbh, if they’re suddenly trying to get a lot of headlines and people interested in it - it might be legit, but it gives off some concerning vibes.

[@TARS..]

It wasn't a coincidence, I'm pretty sure they had a release embargo and very tight NDAs for the information they collected since Helion is still very tight lipped about their tech.

[@Bruh-vp6qf]

Lol "coincidence"

[@zawarudo1041]

It's pr stunt and KZbinrs are cheapest tryhard "legit" sources audience of whose is not that willing to cross check and verify. Mostly, they are excited for new product 😉

[@StefanReich]

I know, right. What are the odds of one company doing two PR stunts in the same month? Incredible coincidence

[@georginikolov8161]

That torus form of the plasma in the reactor on the 3d model was really touching, wonder why this geometric shape was taken. Awe inspiring work - 1+ for humanity.
