Very good introduction to fusion for the non-technical: thanks for posting.

This is so encouraging. I've known since the '70s fusion is our future but there have been so many hurdles to make it work. Now the future looks bright. This guy is right about fusion changing the global political scene for the better. No more wars over oil reserves. No more worries about spills, radioactivity, CO2 emissions or running out of fuel. We just need to write our congressmen stressing the importance and the need to expedite the development of fusion power.

I'll take fission that can be built today and even ignoring the advantages of LFTR can be made to be immune to meltdowns by simply using pebble bed reactor cores and putting the heat exchangers higher than the reactor core. If the "waste" has enough energy to be dangerous it is fuel and if not harmless.

The title is misleading. Where are these fusion reactors working right now?

Could you link some of the studies that suggest that speaking faster is better for comprehension? If so, that's counter what I was taught in college or what I've found to be true teaching my own classes. A comfortable talking speed in which you're able to gauge your audiences' understanding by their body language and facial expressions, and adjust your pace accordingly is the approach I was taught and have found to be most effective thus far. You may understand things more quickly than others if you find everything you watch online slow. But, the reason why I chose the pace I did is from audience feedback, and this talk was for the audience attending, not KZread.

Every time I hear "we need fusion to provide clean baseload power", I just look longingly out my living room window at the geothermal power plant up the hill from me and ask "Why does no one love you?" With improvements in geothermal technology (specifical deep vote and the ability to create artificial resevoirs) we could provide between 40 and 80% of the US energy demand (depending on how much the technology improves) in time scales measures in years instead of decades. It hasn't happened because geothermal is crazy expensive to build, but it costs next to nothing to operate once online.

So there are at least three major hurdles, 1. cracking the hydrogen and the fusion fuel out of water at an affordable rate at useable volumes, 2. designing and building the means to contain the heat involved in fusion (15 million to 200 million degrees), 3. This is a base load source and so is fission, fission cannot be turned up and down rapidly enough to meet usage demand fluctuations, is fusion any different?

see how the conversion takes off.

You stated that Russia and the US were in competition to create fusion power years ago. I'm sure they would have pumped many millions of $ into their projects, but where are they now, did they give up? Strange, if the gains are as you claim. I'm sure you are correct about the benefits of such a power source, but while the oil companies control governments around the World, it is unlikely you, or anyone else will get the funding on a scale needed to make a viable production unit.

And why should investors pour hundreds of millions of $$$ into building a big power plant when Solar and Wind (with battery backups) have gotten so cheap? The upfront cost for a large plant is huge. I'm not saying don't study fusion, because knowledge is good but I still don't think the economics work. And the old economic model of the central utility with its monopoly position is failing. With people pulling solar on their homes many utilities are threatened.

TED seems rather to be a advertising platform for startup companies. As much as I admire the enthusiasm of such young entrepreneurs, now browsing through a number of talks about energy from the last 10 years, always talking about dreams that almost never come to reality has also a sobering effect. The bitter truth is that 90% of the projections made in those videos proved to be totally unrealistic. I know that trying and failing is part of the process, but talking about energy it seems that we're rather losing focus for the actual problems at hand. Realistic experts don't expect fusion to be happening before 2050. However, for the time being there is no technology in sight, that could effectively and economically ease our dependency on coal and gas.

And solar and wind are finally getting the attention and popularity they’ve been needing, resulting in more subsidies that are being given to eccelerate their growth. As solar and wind improve and grow, better batteries will follow (and the plans for solar communities instead of farms also allow for smaller, easier batteries anyway). Tesla and other companies are already working on more renewable batteries. Like I said before, solar and wind are young and are only just now getting funded properly. Besides, even if it does take time to greenify the batteries and we release more CO2 into the air it wont rlly matter. We have already reached the threshold. Even if we all got clean energy right now with a snap of a finger, it wouldnt change the destructive amounts of CO2 already in teh air. With Tesla’s XPRIZE and other incentives, people are already working on solutions to grab that CO2 from the air… I know nuclear is attractive because its simple, but I’m telling you in the long run it will be disastrous and not worth the energy we could have gotten from solar and wind

Four words "Thurst to Weight Ratio." Even assuming you got the super conducting magnets. lasers etc etc and everything else for basically mass free-which is not going to happen but lets just give you that for the sake of argument-you still need radiation shielding and radiation shielding by it's nature is heavy and a LOT of it because the amount of neutrons being given off by by a fusion rocket powerful enough to lift off from Earth... wait a second I can give you the rough GW value a SpaceX Raptor engine puts out about 6.74 GW, so assume you are lifting something roughly as heavy as Starship you would need 134.8 - 215.68GW nuclear reactor... More powerful than any rector ever built by orders-note the "s" there indicating plural-of magnitude, the sheer amount of neutrons being given off would be epic and the shielding needed to stop those neutrons would be heavy in the extreme. and that 134.8 - 215.68GW assumes you are heating what would presumably be hydrogen with some sort of magical heat exchanger which wouldn't nope out of existence in a couple of milliseconds, because your only other option is an open cycle fusion rocket which I am fairly certain using such a craft even close to Earth orbit would be considered a war crime because radiation is bad mmmmmk. Oh and a fusion rocket which uses the spent reactor fuel and the radiation as propellant would need orders of magnitude more power to generate the same thrust as a thermal rocket powered by a fusion reactor, we are probably talking 10's to 100's of terrawatts, which FYI humanity in total uses 17.4 terawatts, so hence why it's would be a war crime.

I suggest the idea: 1) following your description we have to learn from Nature 2) There in stars this whole fusion exists and explosions (totally spontaneous) are counterbalanced by the gravity of the star as well as that is why the reaction starts in the first place there: gravity brings the atoms together 3) here we don't have this gravity but we can easily create a bomb therefore 4) we don't need to stabilize the reaction in one place but we need to create many little bombs and to explode them in water. Once the reaction starts the bomb is going to melt (we have T= millions degrees) This mass should be released to the proportional amount of water and while cooling the reaction would stop but the water will be hot. Like imagine machine gun with bombs like this: cartridge contains several bombs to be, we shoot, reaction starts, it hits the water, reaction ends inside and the water is hot! We just need to evaluate the dimensions of the water reservoir big enough to cool small bombs but it is easy to calculate even with school physics knowledge. But in a simple way we need to cool 1 kg of gas with almost millions liters of water to get the 100 degrees C needed for the water to evaporate. This is not a lot. The problem this thing faces is if the reaction may start another reaction of the hydrogen H2O of water....but I think this is not a big deal, since they do explode these bombs in the ocean and we are still alive. This is a way to get around localizing the reaction in one place.

This young man has expressed the false view, that the spending next 10-20 bilions of USD for the fusion reactors type ITER are equal to solving the energy deficite problem. So I will tell, what this youngster did not tell: The last info from the ITER reactor construction site was, that just the simple increasing the dimensions of the reactor is not the ready solution as the plasma unstabilities have appeared and stopped the progress. That means, that the theoretical description of plasma flow used in the project, was too much simplified, and must me modified for bigger accuracy. After the Schauberger we know, that the fluid flow generates the stream virality and it was not included for ITER reactor. But Germans have built near the Greifswald the reactor Stellarator Wandelstein-X.... , where the plasma chamber is made as the Moebius ribbon (circular ring) , but 5x twisted, and chamber cross section is not circular, but better takes in account the true cross section of plasma stream during the circulation. Already they have reached plasma temperature ca 80 000 000 degrees during some fraction of second. If their results were better than that obtained in ITER, it may indicate some progress-but we need 150-250 000 000 degree and the technology is far from being ready . Still long way is ahead and fission thorium reactor may by closer to drive to industrial maturity. Stary

The problem is that the fusion scientists have been promising they are "real close now" for over 50 years. We should remember that the fission guys promised us energy that would be too cheap to meter... These are very capital intensive projects, which means that there is a huge temptation to over-promise in order to secure funds. So it's hard to know whether teams like this can deliver. Note that he slipped in the phrase "if you want to solve the energy problem now - now being the next few decades", which isn't confidence inspiring. Fusion has been one of the best funded fields in all of science, draining resources from alternative approaches. So I'm not impressed that his main message is a plea is for more cash...

Also, resistant to new ideas with potential drastic consequences being put into effect for the entire country when there has already been in place working methods that haven't cause financial collapse or lowered the quality of something that was already provided by many private sources who develop and compete with each other that have always taken direct interest in what they do and not just a state-funded friend of a politician who does it just good enough to collect and gain profits from public funds while asking for more funding constantly but never showing improvement in way they do things. Resistant to additional social programs that don't directly get funded by taxes but allocated whatever congress feels like in every yearly budget from the total collection tax. These programs often have 50% the total public funding of them spent to support 5% of the population while making 100% pay into it and never even used at all by ten of millions. They can also open the door to putting control for the mindset of adults in the future by giving total control over the educational system to a few people who meet privately and force compliance of the schools by withholding funding unless the regulations are followed explicitly. Dr, evil would love this to indoctrinate everyone still in school to think in specific ways and only know about certain things that were allowed to be part of the curriculum in order to gain 100% approval of the next generation of voters on their personal ideals or desires. ( World Domination is Dr. Evils case. Massive profits and power in the case of corporate and international interest groups and the super rich at the top of the 1% who can buy the support of large parts of government and the media to manipulate public opinion and have those propositions that do WAY more then just the 1 little thing they tell you to VOTE yes on it for. ) Government taxes should pay for things that are impossible for private industry or individuals to accomplish such as the massive costs of researching new energy sources that may massively affect the future of the species if solved like fusion. This way failure results in public knowledge and doesn't destroy an industry. Also, interstate highway, military, and infrastructure that would be beneficial for the whole country and all of those who live within it. It shouldn't use law to regulate the healthcare industry so that those who lobby politicians get to write the rules and become a monopoly and require something like every public classroom in the country be required to have 2 EpiPens available regardless of their being students who need them that expire after a year and cost $600 each now because of the scum that owns the patent on it even though they cost something like $2 to produce and any parent who care for their kid who has a condition where they would need one would obviously supply them as needed if they were available a reasonable cost. This is just one example of the costs to society of centralized control of everyone's lives and then putting them in the hands of whoever got the most campaign funding from the special interest groups who will use them to write policy for personal gain regardless of the cost and development of society.

Why don't we use the profits from Thorium to develop fusion. And by the way a well developed network of LFTR like power plants would also enable smaller modular reactors on big ships for example where the difficult parts of the chemical processing can be left to the plant making the mobile reactors more closed, simple and smaller. And I think later they would work very well together with fusion too because some fusion designs already took the idea of a Liquid salt coolant and since fusion produces high amount of neutron radiation, it would probably be good for breeding other nuclear fuels that can be used in much simpler and lighter reactors for example in space.

The issue with that is that fusion power does not scale linearly with size. In fact, the total power out scales as the volume roughly. So, it makes perfect sense to increase the size of the reactor while maintaining bulk plasma parameters to increase the total power out for a given physical footprint. It's not a problem that as you get bigger it goes unstable, it's just that building bigger reactors requires more money and people are less likely to spend more money on an experiment that might fail. So, we try to do as much as we can on smaller reactors, but there will always be uncertainty going up in size from there.

Please make that nerdy talk. It's been a while since I learned anything significant from a TED talk, sadly.

Will do. Funny enough the talk it sounds like people want on here was my original talk, before I had to water it down quite a bit. I've been super busy lately but in the meantime before I put up a nerdy talk I'd like to direct you to our start-up website (not the prettiest yet since it's made by yours truly), www.ctfusion.net. Then, on the press page, we have a set of our main journal articles about our approach to fusion. My nerdy talk will likely be the geometric mean between the level of detail in our scientific journal articles and the level of detail of my Ted talk so that it's still accessible for a reasonably sized audience that aren't experts in plasma physics. Thanks for the feedback everyone. I really appreciate it.

I guess the people who got what they wanted aren't grumbling here in the comments :-) So the TED people _might_ be right... I'll check out your site.

A nuclear weapon based on radioactive water. Wow!! Something's we don't need. Magnetic field moves cranks the coils through the magnetic field using the armature magnets. An Edison generator was.used and a normal way of generating power.

The Tokamak fusion reactor is over 50 years old, but being with held.

I see no advantage to fusion over fission, the difference is we have fission right now and understand it very well. We know how to make reactors that will eliminate the waste we have thankfully stored so well. No mining for the foreseeable future and nearly free fuel. Extremely safe, clean, and abundant, what's not to love?

@@mrcleeves7106 Well, the French have been recycling waste for decades but that's an expensive process. Molten salt fact reactors will use the waste with little to no reprocessing. Moltex Power is building its first reactor in New Brunswick Canada and Elysium Industries is a bit behind them in the US with a reactor that requires not reprocessing. Both have excellent presentations here on KZread, or you can go to their websites.

Hi, Mike. Please give the model number of your panels as well as the model number of the grid tie inverter you're using. If you could provide links for them, then that would be awesome. Also, what's the voltage of each panel? How did you wire/group them together? Thanks, Mike.

If you are having difficulty in sourcing for funds, you should contact China directly whom I'm sure will be more than willing to fund thou completely. This is project for mankind. Look for the sponsors who have the same ideas.

The way to go must be Thorium, Fluoride Stable Salt mini reactors which are very small, cost effective, can be dug into the ground, can be transported conventionally etc. the reactors the guy above is talking about is just a new way to maintain the current centralised over priced electrical grid. Tiny reactors that fit in the back yard or in the car are the way to go, get away from the corporate run grid.

If all of you listen he say its a VISION! He knows its more work to do before we are in the green!

Hopefully it actually works.

You are forcing energy against itself, it;s not perfect, and therefore, it's not the solution

By the time fusion technology is available it will have been eclipsed by battery backed up solar for 1/10th the price and 1/1000th the difficulty to roll out.

Always the industrial scale for profit that you have to buy thru a wire. Meh...

They said the same to nuclear energy. And what about the waste If its ever works? Tztztz nothing learned.

other nuclear reactor...!

You think nuclear energy plants are expensive to maintain? Grab your socks...

why didn't this super smart plasma physics mention (thorium salt reactor)? that's something safe, and it's already been done 1965, and super cheap enough. so why not Even explain all options for nuclear power? Because of his agenda.... He's not A thorium physics. and he's the CEO. that would scare me away from investment in plasma reactor, with a running temp of 200,000,000 degrees, that would melt your face straight away.. we've almost worked out all the kinks, so we just need more of your$$ because the CEO needs to be paid. No matter if it's earned or not. eventually we'll get it right. Last chance to get in on this great investment opportunity, so call now.. THORIUM salt reactor can't make nuclear weapons ether, another set back for the elite oligarchy deep state military industrial complex scumbag pedophilic self-absorbed plastic polluting assess.

@@joebopp01 sure. It's called wind power, which ultimately is derived from the sun, as Mr. Sutherland briefly mentioned in this talk. (The sun heats the atmosphere on one constantly-changing side of the Earth. Heat radiates out to space on Earth's night side. These temperature differences create convection currents - winds.) In addition, there have been plans for long-distance power lines to distribute power from sunny areas to less sunny ones and around to the night side.

@Carl why try to replicate? Because not every energy load can be practically met by a low energy density system totally reliant on solar panels and wind farms.
