How is this going to be viable for producing electricity in the future? Even if you could perfect the process and ignite the fuel entirely, there's no way you could fire it multiple times per second so what's the point of this? If there's something I don't understand I'd be more than happy to read your comment but I really feel like these projects are just scamming investors with the buzz word "Fusion".

@@Alfred-Neuman use a bigger fuel capsule to heat up a large volume of coolant and then run steam turbines off the heat in the coolant volume. You're harvesting the energy from small bombs.

It's really not that hard to produce fusion, but it's finding a method that can produce a lot more energy than you need to put into the system, and this method is probably the worst way to do it. But apparently it's the easiest if you want to make a tiny bit of fusion and use this to get money from dumb investors...

Well.... Cooking food was the first "energy revolution". It allowed humans to gain far more energy from our food and was likely the main reason why we grew big brains. Then we harnessed animal energy so we didn't have to hunt and could use them to help plow fields when humans unlocked the agriculture skill tree. That work pretty well until the industrial revolution, now we had machines take over a lot of labor. Though wages were low, unions started and slavery was eliminated around this time. It seems that every time we harnes new energy, humans grow up a little

I know a little about the team at FLF, and they're all fantastically passionate and knowledgeable. Something to note about their approach is that they really started with the engineering challenge, rather than the physics one. Everything they've done focuses on identifying the real engineering challenges for scaling up, and either focusing on those or eliminating them. If they are successful with their next machine, it is likely going to be easier to commercialise at scale their solution than many other concepts. But that isn't even the best thing about FLF's work - so much of what they're doing has other commercial applications beyond fusion power generation, potentially giving them a sustainable income stream until a demonstration power plant can be built. Like all fusion contenders, it does have loads of real issues road blocks still in its future, but at least FLF seem keen to identify them early, rather than view it as a problem for the future. For the curious - if I recall correctly, the demonstration reactor we see in the CGI footage is using molten lead, and is intended to operate similarly to a molten salt renewable plant - turn an intermittent heat source into a steady source of heat that can then drive steam generation.

It would definitely useful for residential or greenhouse heating. And, if in summer you produce electricity mainly for running air-conditioning... the overall efficiency is catastrophic and could be qualified as a ponzi scheme: **Comparing Nuclear-Powered Residential Air Conditioning Systems and Ponzi Schemes** At first glance, nuclear-powered air conditioning systems and Ponzi schemes seem worlds apart-one being a technological solution for climate control, the other a fraudulent investment strategy. However, on closer examination, we can draw an allegorical comparison between the two in terms of sustainability and the broader implications of their implementation. **1. Resource Input vs. Output**: - **Nuclear-Powered Air Conditioning**: Nuclear power plants, while efficient in electricity generation, produce significant amounts of excess heat. When used to power air conditioners, there's an ironic twist: while homes get cooler, the environment outside heats up due to the heat discharged from the power plants. - **Ponzi Scheme**: Investors are promised high returns with little risk. Initial returns are paid using the capital of newer investors. As the scheme grows, it requires an ever-increasing flow of money from new investors to continue. When that inflow slows down or stops, the scheme collapses. **2. Unsustainability**: - **Nuclear-Powered Air Conditioning**: If most households were to rely on this method for cooling, the aggregate heat released into the environment could exacerbate global warming. The solution (air conditioning) inadvertently becomes part of the problem (heating the planet). - **Ponzi Scheme**: It's inherently unsustainable. Since it relies on a continuous influx of new investment rather than genuine profit, it's destined to collapse eventually, leaving late investors with significant losses. **3. Short-Term Gains, Long-Term Implications**: - **Nuclear-Powered Air Conditioning**: In the short term, homes are comfortably cooled. But the long-term implications of widespread adoption could be detrimental for the environment. - **Ponzi Scheme**: Early investors might see significant returns in the short run. However, the long-term reality is potential financial ruin for those who join late. **Conclusion**: While nuclear-powered air conditioning and Ponzi schemes operate in entirely different spheres, they both serve as reminders of the need for solutions that are sustainable in the long run. Whether we're discussing energy or investments, it's vital to look beyond immediate benefits and consider the broader consequences of our choices. Off course using Gas powered electricity for air-conditioning is even worse

@@SwissPGOI appreciate your well thought out concerns however the heat generated during power production, which currently occurs with most of today's power production as well, is a very little consequence to the global warming issue. The heat we produce generating power here on Earth is miniscule in comparison to the heat the Sun transfers to Earth on any given day. That's why with climate change we're worried about CO2 which more effectively traps that heat rather than the heat generated by CO2 sources which in most cases is a lot of heat in human terms. However in global terms this heat is minuscule and would also be with nuclear powered air conditioning. I mean yes maybe in a thousand years as energy demands increase further you might be on something but that problem is truly a very long term problem. Additionally wow intermittent renewables plus storage are great and should be scaled up as much as possible The material inputs for most storage technologies are not insignificant and have their own environmental concerns. As a result we need base load that is relatively materially efficient and nuclear whether fission or fusion does a great job of this. In the end I am confident that it will turn out that we need both lots of renewables to power industry during the day plus some storage to help with peak demand in addition to a good bit of sustainable bass load such as nuclear. Additionally in the case of nuclear fission, with the right fuel cycle you can drastically reduce the need to mine for fuel as well as reduce the amount of high level waste you would need to store.

This all reminded me of a somewhat counter-intuitive issue that CERN had way back around about 2000 dealing with the high volume of data coming off the LHC at high data rates. I was dealing with their IT people as a supplier at that time and I remember being told once that one issue they were having in terms of optimising the cost of their infrastructure was that they couldn't source disc drives that were small enough. Yes - small enough! The issue was that in order to support the data rates they were having to parallel up multiple drives to service a single data source, essentially widen the data bus significantly to get the write speeds to disc that they needed to be able to keep up where it was the sustained write speeds of the drives that defined the minimum number of drives they needed to parallel-up to service a given data source. The issue that then niggled the IT staff was that the smallest drives they could get, once they put a load of them in parallel, meant that they were forced to over-provision the storage capacity by a quite significant amount.

@@saumyacow4435Fusion technology is still in the embryonic stage. Deuterium-tritium can be used for fusion reactions and is extremely cheap; around $1 per gram, because it can be produced from seawater. The infrastructure for the fusion reactor itself is currently expensive because we haven't honed the technology yet. Consider the first hard drive to exist was only 5 megabytes in size, yet it cost $33,000 in today's money. Now think how cheap an 1,000,000 megabyte drive is today; less than $100. Renewables aren't really cheap when you consider it as a cost vs energy generated function, even more so when we consider the stability of energy output which the power grid requires to function correctly. They're also not reliable in terms of ideal conditions to produce that energy; eg solar panels don't function without sunlight, but they also produce less energy the hotter they get - from sunlight. Also consider that energy storage is not only costly but it creates a highly explosive failure point if we wish to store enough energy to stabilise the inconsistent energy production inherent to renewables. All renewables; wind, solar, wave, hydro, et al, all fail to produce power all of the time, even if you have all bases covered there will be times where there is insufficient power generated to sustain the grid. Once fusion has matured it will be extremely cheap compared to renewables. The amount of land required for renewables, and resources, will eclipse that which is required for a single fusion reactor by several orders of magnitude. I've worked as an electrical engineer and an instrument & control engineer in renewables, oil & gas, reactor design, robotics design, and now defence. I appreciate you're optimistic about renewables, but it seems you're not entirely aware of not only the shortfalls in their capabilities, but their extraordinary cost as well. A fusion reaction is like a miniature sun, so in essence we're generating "solar power" without all the extra steps that renewables requires!

They are able to directly extract electrical energy from the magnetic field of the fusion pulse. No super heated water, no neutron generation (causing containment damage), no steam turbines, and it easily cycles for the next pulse.

I've been really interested in fusion energy, have learned quite a bit about it over the years, and all the different approaches. This approach is very interesting but I'm sceptical about their 2030 target. Fusion energy has been theorised for well over 80 years, but investment has historically been extremely low. Only in the last 10+ years have private enterprises got involved, but they're effectively starting from scratch. There are post-energy production concerns as well, such as how do you get the tritium, which is not abundant and is currently EXTREMELY expensive. Even ITER are starting from scratch when it comes to Tritium production. I predict they'll still be in the experimental stage by 2030 unfortunately.

How much time does it take to machine one of those launch disks, that seems like its going to be a huge hurdle to overcome - do they need more than just a finishing pass after being casted? It looks like their mock up for a at scale reactor has 72 locations for launching and each one needs to launch every 90 seconds which means they need over 2750 of those launching disks an hour. If it just requires a finishing pass that still probably 1-2 hours in the CNC, so that averages 4,000 hours , so in order to produce at a rate equal to consumption you need 4000 CNC machines and even if you assign a 6 machine cell to 1 machinist that's 667 machinist. You are also going to need 3 shifts (or two 10s) so that's 2000 machinest on staff per reactor so every reactor has a machinest labor cost (excluding material and cost to cast) of (assuming the average UK salary for a machinist of ~32k USD) 64 MILLION dollars per year just in machinist labor for those disks and that's being generous, if they need more than just a finishing pass to go from rough casting to final it's going to be 2-3x higher.

It all seems exciting until you follow engineers with a background in the industry. They point out compelling reasons for believing that none of these commercial projects are anywhere near to producing power on a commercial scale. In this video they are giving nothing away about how near they are to fusion, the costs involved and the energy in -> energy out they hope to achieve. This looks more like blue-sky research than production engineering. Given that they have to keep investors on-side, any claims that these projects do make need to be viewed with some scepticism. What few are reporting is that the "breakthrough" at the NIF only produced a tiny fraction of the energy injected into the system. It was a military experiment and the relevance for civil power generation is minimal. I sure hope that I'm being too cynical - we desperately need more clean energy. But the difficulties of achieving viable fusion power are so formidable that I suspect we should be investing most of our effort into more pragmatic and better understood options.

Fusion research needs a rebranding. Instead of touting it as future energy they should be honest and call it basic research. Stars produce energy through extreme mass, pressure and density. Every fusion-energy project is trying to recreate it with a vanishing fraction of mass. It irks me that people will latch on to fusion-energy as the answer to our problems. Never noticing that we already have a working fusion reaction at the centre of our solar system. And we have the technology already producing grid-scale electricity less expensively than coal.

@tullochgorum6323 Жыл бұрын

@@CarFreeSegnitz I'm no engineer, but I believe that creating fusion on earth requires far more extreme conditions than are found at the centre of the sun. Fusion in the sun is very inefficient, but its great mass means it still produces huge amounts of energy. Economically viable fusion of earth would need to be much more efficient. This is a tall order, to put is mildly. A better sun than the sun... The industry has done a fantastic PR job when it comes to accessing $$$ from governments and investors. But I don't see many signs that they are much closer to producing economic power generation than they were half a century ago when I first started to follow the saga. By contrast, my smartphone is billions of times more powerful than the room-sized supercomputers of 50 years ago. I sincerely hope I'm wrong, but I simply don't believe these claims that they will be building power stations within a decade. As you say, better to focus our talent and investment on improving and actually building the technologies we already understand. Because relying on fusion is far too much of a longshot.

all current fusion has 2 main issues: - its not continual energy generation/ignition, but only a single burst, that also destroys the core of the "engine". - preparing and running the scientific experiment is VERY energy inefficient, and it costs way more energy in computing power alone, in a second, and the computers run for days, to generating energy in an ignition- burst for less than a second. this is just not a power plant, and for a LONG time will never be one. but still, fusion ignition finally has been done , which is when you get more energy out of something than from the system, by igniting something, just like burning wood. so the above 2 are engineering issues, and not longer physics/science to-be-tested. still they are HUGE engineering issues, and you get single-fire LASER riffles and laser grenades from that (with very dangerous and inefficient battery packs) long before you get power plants from it.

By the way - as regards ultrafast diagnostics they need to talk to physicists working on X-ray Free Electron Lasers. There, the time scales are Femtoseconds - one millionth a slice of the nanoseconds they are looking at. They are even now looking into working in the attosecond regime (billionth of a nano second). By comparison the nanoscale is slow time.

All of these fusion programs are 1000s of times more complex and expensive than fission esp in say the Molten Salt Reactors like Moltex, but hey lets worship fusion because its slightly similar to stellar fusion, (it isn't remotely anything like the sun of course).

Yes, it remains a science experiment. Even if this approach gets passed breakeven there’s the matter of expended machinery. It’s “only” a matter of scaling up the production of the machinery. When the system of rebuilding reactor components is taken into account this approach will net-out at 1-2% efficiency like all the others. The real benefits come from the technology used in the approach. The NIF benefits come from the laser tech they’ve improved on. This approach will get us the air-gap switches and launching disk.

Ex Navy Nuke here. All these "breakthrough" fusion startups need to present understandable net energy in/ energy out and thermal efficiency data to even prove this is even remotely viable from a thermodynamic standpoint. Not being a downer but there is a reason why fission nuclear power has been around for 70+ years with hundreds of reactors where as fusion has remained (and will always) be a science research pet - project for academia, governments and venture capitalists who don't understand science. Consider from this standpoint all the thermodynamics here: 1. Gunpowder Requires manufacture of components potassium nitrate, sulfur, and charcoal 2. Projectile(s) Not much info given but that requires energy to manufacture (even as a prototype proof of concept). In a production version, what will replace that? 3. H2 (hydrogen) Hydrogen has to be created by and if done so mainly from fossil fuels or the electrolysis of water 4. Burst Disk Consumable and inefficient for any time of production unit; how can that even be taken to production? 5. Deuterium and Tritium Production These are energy intensive to extract/create and Tritium requires a fission nuclear reactor; cost prohibitive 6. Capacitors All those capacitors cost a lot of energy to manufacture 7. Parasitic losses...? 8 Cost of construction....? 9. Hooking up a viable and efficient heat exchange system....? 10. And since everyone is so 'carbon conscious' is this even carbon neutral? Even if 'viable,' how could it even function in this manner? Some sort of reciprocating assembly to do the compression? We need genuine and critical reporting of fusion instead of this misrepresentative hopeful hype.

How are they going to process the resulting highly radioactive metal? 3. From what I understand, they're using "drop the target, fire the disc" routine. Their BFG may demonstrate the viability of the amplification, but have they demonstrated the collimation, ie making sure the projectile hits the target at exactly the right orientation?
