Nuclear power has a controversial history, but many energy experts say it has a major role to play in our energy future. Some in the industry are working to make standard fission power safer and cheaper. Others are pursuing the holy grail of energy – nuclear fusion, the process that powers the sun and the stars. If we figure out how to harness that power here on earth, it would be a huge game-changer.

Is Nuclear Fusion The Answer To Clean Energy?


  1. August '21 Update : In a breakthrough result, the NIF managed to achieve ignition for the first time in the 60 years of its existence.

  2. We are at a turning point in humanity. Nuclear fusion will not save us from our-self unless the people in power make the necessary change to our basic survival need that include the environment. Energy is only a drop in the pool, we can't survive (human) without a clean Earth. The Earth will survive with nuclear energy or any thing else, or us or not. The cockroach have been around for at east 140 million years. Witch one will make it?

  3. "… about 20 yards in diameter…"
    Scientists who use imperial units gives me pause…. Yes, it's about a chain in diameter…

  4. Instead of a hot plasma, have scientists tried cold fusion by cooling hydrogen to nearly 0 Kelvin and applying electric current and megatons of pressure to it?

  5. the fact that modern nuclear fission reactor is extremely safe never convinced public trust.. the media and fake green activist should be responsible..

  6. Wind and Solar farms are just overrated. Intermittent power, unreliable, utilizing lots of resources to building and maintaining. Just look at Germany they closed all nuclear sites and now they are using coal and gaz to generate electricity when the wind and solar is not enough. Even if nuclear is not 100% green energy. It is the most reliable, most eco friendly way to generate power for now.

  7. Nuclear fusion, deuterium-trithium, which is the only reaction that we will ever could hope to ignite, has an output that is made 80% of fast neutrons, and 20% gamma radiation. These neutrons have to be slowed into a containment to extract thermal energy. Alas, in the process such neutrons produce a humongous lot of radioactive materials due to neutron activation, also slowly destroying each and every material of the core. "Clean" nuclear fusion is nowhere near as clean as it is sold to the public.

  8. There Is No Shortage of Energy; There Is Shortage of Normalcy

    Despite increased production of energy from renewable sources, and despite the slowdown in car manufacturing, oil prices are skyrocketing. Even though fewer power plants still burn coal, coal prices are skyrocketing, as well. Natural gas prices, too, are going through the roof, and energy demand seems to outpace supply in every country and in every form of energy. Have Earth’s energy sources dwindled so drastically in a matter of months? The answer is a resounding “No!” There is no shortage of energy; there is a serious shortage of normalcy in human relations. I hope the current crisis will put some sense into humanity’s insane consumption.
    The energy crunch indicates that we are over consuming. We are producing too much, throwing the excess production to the trash, polluting the ground, the air, and the water, and then we are complaining that we do not have enough. It is about as sane as killing one’s parents and then pleading for the court’s mercy because I’ve recently been orphaned.
    It is time we reconsider everything we produce—how we divide production, profits, and goods, which services are necessary and which are redundant, and most importantly, how we treat one another. The goal of this process should be clear to everyone: survival.
    There is no ulterior motive, no attempt to dominate or deprive anyone of power or wealth. It is simply that reality is forcing us to take all of humanity and the entire planet into consideration. If we don’t, our entire civilization will collapse like a deck of cards.
    Since we still do not understand it and insist on running things the way we have always been running them—through power games—I anticipate a very cold and gloomy winter for the northern hemisphere. The energy crunch will leave many in dark and cold houses; there will be no gas for cars, and renewable energy will not replace traditional sources since there will be little sun during the winter. I hope that at least, it will make us rethink our values. If it doesn’t, next summer will be even worse than the awful summer that just ended.
    I know that many people are counting on the promise of renewable energy to solve the energy problems of humanity. I think they are mistaken. There is plenty of energy, far more than we really need. We could cut emissions by at least half tomorrow. But the more we have, the hungrier we become, so our thirst for energy will never be satiated, and we will never stop exploiting the planet or each other until we reeducate ourselves and start being humane toward each other.
    We have been behaving like spoiled brats whose parents buy them whatever they want. Now, our parents have run out of money and our childhood is over. It is time for us to mature and conduct ourselves like responsible adults, caring for all of humanity the way a mother cares for her entire family. If we think like a family, we will achieve normalcy.

  9. Why human kind don't look into nature to move things around, always some force to smash instead of connect together…

  10. As promising as Fusion is, its not a question of can we invest further into it, but if we should

  11. Lack of funding for these types of things is ONE of the reasons I didn’t vote for trump lol

  12. $RABBIT FINANCE 🚀🚀🚀🚀🚀🚀🚀🚀🚀🔥🔥🔥🔥🔥🔥🔥🔥🔥🚀🚀🚀🚀🚀🚀🚀🚀🚀💯💯💯🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🔥🔥🔥🔥🔥🔥🔥🔥🚀🚀🚀🚀🚀🚀🚀

  13. Fussion only needs temperature? Consider the sun's gravity is a joke?

  14. In order to run, many parts of the body must make a coordinated effort. Mankind must also make a coordinated effort in order to make the greatest progress in all fields. We are all one and the same thing before we come to earth for this life experience, the closer we get to working together and getting along, the closer we get to the true reality of what we are before and after this life. This is when we will be at our best and technologies we can only dream of will solve our greatest challenges on earth and take us to the farthest corners of our universe.

  15. Ok Fusion is the answer . …Cold Fusion ..Yes.. ( In space it is very cold.. so the reaction will be closer to a natural time dimple.. or the feald that supports and compresses planets. And the Sun. the Field should have a liquid nitrogen jacket or suspend the plasma in a body of nitrogen..
    As for the Nuclear waste .. build a rocket.. load it and 1 by 1 we send them to the sun. The sun could benafet from the extra fule?? .. Just my thoughts much love from Russ .

  16. All though liquid Nitrogen will repell a magnetic field or help to compress is in less power to the magnetic field……???

  17. free energy concept should be encouraged…..fusion is a good idea but it will take time …pramhnsa tiwari
    an Indian scientist achieved more than 250% of efficiency ….means totally free energy……

  18. Fusion power is the energy source of the future. Always has been, always will be.

  19. how about installing scrubbers on coal power plant funnels? purify the used water by centrifuge and utilize it again, collected carbon will be dump on deep landfill

  20. Solar and wind are cheaper and people are not afraid of them. Expansion of either form of nuclear (at least in the US) really has no chance in the next 50+ years.

  21. that 22 billion dollar project has been way too slow. but best solution is hydro-electric still but because of demo-graphics and cost even they are going bust.

  22. this is stupid to associate nuclear energy with nuclear power same atoms, 2 different technology, really

  23. Black hole of tax payers money for the life career of few

  24. They can’t even take care of the spare rods they already have. Just put them in big containers and not checked to see if they are leaking into the ground water? The guy at EPA that was head of that division, had a red passport and didn’t show up to work for three years. They have improved anything since then? Actually, it’s worse now.

  25. Energy cannot be created or destroyed, only transferred. You have to harness it in intervals and release. Good luck with that…

  26. Funny how they dont even talk about hydro electric energy of Canada

  27. 2:19: "a pair of German researchers". Namely, Otto Hahn, Fritz Straßmann and Lise Meitner.

  28. Fact: deaths caused by fossil fuels in the last 50 years 100,000,000, deaths by clean energy accidents 250,000, deaths directly caused from radiation in Chernobyl and Fukushima was 52. I'm talking about direct deaths

  29. Let's not get tunnel vision, we need to look at all technologies. Unfortunately, we have to involve politicians who are short sighted, greedy, and never look beyond the next election.

  30. Lol the nuclear powerplant at 3:20 is located in Switzerland, Gösgen.

  31. “A pair of German scientists discovered fission?” You are so lazy that you can’t even be bothered to mention their names? WTF, CNBC?

  32. I wouldn't trust anything that has Gates finger prints on it.

  33. Biggest reason fission is going away in the U.S. is that it can't compete with natural gas cost wise.

  34. by the time they invent fusion reactors. we will be old and gray

  35. Wind and solar are popular and work because of our sun…why not just make our own sun problem solved.

  36. Didn't Dr Octavious already try that and then spiderman had to save the world?

  37. Why is everyone still hyping up ITER when the technology it relies upon is already obsolete?

  38. 18:00 ish. Why don'T you just create filters so to CONTAIN the emitted CO² out of coal/methane powerplants? And when the filter's full, just clean it.

  39. It was me who made Bill Gates, creating his achievement profile more and more with Microsoft. I outlined the timeline of technologies of Microsoft and other computer tech companies in conjunction with each other's technologies, initiating the design of MSDOS, Windows, MS Office, Visual Studio and Xbox, etc.

    I "also" helped Bill Gates in his nuclear energy ambitions, planning up our TerraPower project, using our nuclear power technologies.

  40. Why is the American government so out dated? Why don't they support fusion research simply because they understand how important this is? Are they all THAT stupid? I get disappointed in the US time after time after time after time. So rich and doing almost NOTHING good with that wealth. Ten multi-billionairs can easily support fusion research, but all they do is building another superyacht. Each year again! Why do the less intelligent get all the power and all the money? That is absurd! Is it corruption? Is it discrimination? Can't you possibly change your political system to something useful?! You citizens are not even considered wise enough to vote the next president THEMSELVES. OMG, no, the senators must do that, the people has nothing to do with the president. If I were an American, I'd protest until the fools in power would shoot me. And after that week? Business as usual, of course. Poor US. Extremely poor US. United? Okay, poor States.

  41. Already built and proven Thorium reactors {at Oak ridge} are the answer.

  42. Why not build the nuclear powers underground? 🐁
