@Hermetics Before you finish your book try and learn how to spell.

I saw this and wondered if it was going to be another brain dead clown spouting off about stuff he knows nothing about. FYI - I'm an aerospace engineer who works in industrial control systems, automation and robotics. This is a great honest technology video and we need more people doing this sort of thing. Just be careful on your titles. Yes I know you need to get people to click and watch but its also easy for people with technical backgrounds to just go by and right you off. Its also possible people who ask technically qualified people will look at a title and tell others you're an idiot. I watched 3 other of your videos Nuclear Fusion Breakthrough Rewrites Laws of Physics Why China is Building an Underground Nuclear Lab How This Hole Generates Infinite Energy They were all really good and each and multiple points I had not heard. I really did get something out of each one. But look at your titles. In the first one was ok, except no laws were re-written just a theory and your explanation of what they now know was superb. The second was fine, but the third was a but like the first one. The video was fine and informative, but you know there's no such thing as "infinite energy." Even our sun will one day run out of fuel as all stars do. I'd really like to see you do a follow up on geothermal systems. The public perception on it is fairly poor. Except for a couple of rare places like New Zealand and Iceland its pretty much been a failure everywhere else its been tried. We've had a couple of spectacular failures here in Australia. They started Ok but once they started removing energy from the hot rock, the hot rock got colder which somehow surprised them. This is that problem you mentioned of not getting the stream hot enough to efficiently power a turbine. That's also the main problem with nuclear fuel pellets. Its not that they stop producing heat they just don't produce enough to power a steam turbine. I actually think people need to start looking into heat recovery systems a lot more. I came across a European company a couple of years ago that had a process that needed as little as 120C to generate power. There's a lot of processes with heat waste around 200C. They were very quiet about what they did but I suspect they used the same basic process as a steam turbine system but with a fluid that had different properties including a supercritical temperature point that's a lot lower than the 600C of water. Keep up the good work, just watch those titles.

@lolicantthinkofabettername3437 There's nothing new in the He-3 discussion. I actually met Harrison Schmitt back in 2002 when he was in Australia for the 30th anniversary of Apollo 17 and he was pushing for a $20 Billion mining project for it on the moon. It was one fo the main reasons I went off to the mining industry so I could get some practical experience with building and operating mines. The biggest issue with mining ANYTHING in space (including He-3) is the NONE of the promoters have any idea what it takes to build a mine, operate a mine or transport the mines products to where they are needed. A lot of what's proposed is so ludicrous and idiotic its not even worth calling science fiction.

@L4JP Agreed it does NOT engender any sympathy whether he's just trying to be a smart ass or if he actually believes that crap.

@ccibinel Its hard not to agree. There's something 125,000 tons of spent fuel rods in water tanks under reactors around the world of which around 80,000 tons is in America. if there is one fundamental technical detraction its that like all Fission Reactor types they take a damn long time to build. The world should have had a way more sensible discussion on nuclear energy some 15 - 20 years ago, BUT the emotion of what had happened at Chernobyl and then Fukushima killed any rational discussion. For too many people they just hear the word nuclear and they lose their minds and you can't even get to a discussion on any of the alternative technologies like SMR, CANDU, MSR, Thorium or things like safety systems including fail safe systems.

@odeball22 Who and what are you referring to DK-HED?

@william breen Go and watch any of the decent documentaries on ITER.

@nobot99997_xxl Th heat isn't the problem you think it is as its confined to the plasma and there's actually very little mass in that plasma. On the transfer problem that's been known ever since people first put forward the idea of having giant solar power stations circling the Earth. How do you send the power down and its not simply just down the distances are massive. Geostationary orbit is 35,786 km (22,236 mi) in altitude above Earth's Equator.

La maison Rock du Procrastinateur Go watch Peter Zeihan talk about demographics. The worlds population is about to start shrinking, because all the developed countries have low birth rates. The developing world will soon start following as they develop further. Peter Zeihan believes China's population will drop by 1/2 over coming decades because the "One Child" policy worked too well.

@william breen If its the original comment then its real easy to have people distract your material and not even bother if it looks like click bait and there's not only a lot of click bait out there most of it is for garbage information especially on technology. And some of those so called technology informers are incredibly bad and yet they have millions of subscribers. I can't say I agree with everything this guy says, but he's well above average and we do need better content for technology. So I 'd hate to see people skipping past his vids because they see him as just another click bait clown.

@nobot99997_xxl Did you do that from your phone or is that how you normally ask questions and make statements. Because nothing you said makes sense or has any logic or facts to base it on.

@nobot99997_xxl You make claims than you cannot back up. You said the temperature is too high and it will melt the reactor and that's garbage. None of the Tokamaks or other experiments have melted despite having plasma temperatures in the millions of degrees. The plasma is trapped by the magnetic fields and its only a small stream right in the center. You made the claim the must run for 7 seconds. Where does that come from? Don't pull data out of your ass and expect people not to react. If you actually are German then you should know about the Stellarator which I think has a far better chance of working industrially than the Tokamaks like ITER. But that doesn't mean ITER wont be a valuable facility. I saw a great documentary on fusion a few years ago. It included many variations and projects that people had under development including the ITER and the Stellarator. Michel Laberge the founder of General Fusion in Canada who are developing a process using lasers said that ITER is totally impractical as a commercial power generator, but because of its capability it will answer a lot of questions. All that said I have no hopes that fusion will be working industrially anytime soon. Look at how long ITER is taking to build its impractical to think it will solve the worlds energy problem. BUT its possibly going to be a major step forward.

@nobot99997_xxl Those are all valid parts of the ongoing issues of trying to pout the sun in a bottle. In a star its gravity that causes the compression and you only need to watch some of the footage of the surface of our star to see that its incredibly turbulent. That's part of the differences between Stellarator and Tokamak. Tokamaks are supposed to operate in bursts not continuously like Stellarators. The problem with both has been getting enough magnetic power to drive the process. My bigger concern for several years is that the mechanism for getting heat out of the plasma is fast neutrons, not radiation as in photons. Fast neutrons come of and hit atoms in the walls and impart kinetic energy as heat. This is also how they hope to generate more tritium. The problem with fast neutrons is they are the deadliest from of radiation known. They smash up DNA. There's also the problem of using superconducting coils in the magnets. Super conducting materials don't like getting hot so when you're wrapped around a giant heat source you need to keep them cool and cooling requires energy. I don't think their chances of delivering anything soon are good, but then sometimes people make genuine game changing breakthroughs.

@nobot99997_xxl The ARC reactor design sounds interesting and they are certainly tyring to do some lateral thinking. I hate to say it but those MIT kids are very smart and when they get things right it can be brilliant, but for every piece of brilliant they also tend to have a bunch of failures. Go look up what happened with the WAMSR (waste annihilating molten salt reactor). They did a TEDx where they announced to the world how they had solved the great problem of nuclear waste. Right at the very start they missed a couple of things and their concept was NEVER going to work. It was a shame because the idea is brilliant. I actually wrote to Leslie Dewan and encouraged her to not give up but to look at the problem from other perspectives because being able to eliminate the waste stockpile would be one of the greatest technical achievements ever.

@nobot99997_xxl I'm quite well aware of not taking things from YouTube or TV or the any other media as gospel.
