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.

    Nuclear currently is not a magic bullet,it could destroy us more than save us, plus nuclear is increasingly too expensive and produces waste we really don't handle well. . It has to be part of the mix until all fossil fuel production ends but there are greener alternatives which don't bring the same risks as nuclear. We should be focusing on alternatives to fossil and nuclear in the longterm.

    I'm glad to hear there's ongoing improvements (evolution) of nuclear fission regarding efficiency, less waste, etc... but I hope that nuclear fusion becomes viable soon (within a decade) and more importantly (to me) that every trace of nuclear waste can be safely eliminated.

    Omg it’s so infuriating. Instead of focusing on some pie in the sky fusion reactor which has had no successful reactors made in 60 years of vigorous trials. Meanwhile there’s thorium reactors which have been tested and proven to work for 50 years. It addresses every issue with fission. -No potential for reactor to go into a runaway thermal reaction. - no nuclear waste byproduct -far more abundant and easily found in comparison to the uranium or plutonium isotopes utilized in fission reactors -yields far more energy than fission The only reason the US didn’t go forward with thorium in the 1940s, (bc it had already been tested and demonstrated to work flawlessly) is ironically because its reactor didn’t produce a nuclear waste byproduct and therefore didn’t lend itself to be weaponized into nuclear weapons. Well, that was clearly a mistake we can and truly must in our current competitive technological landscape. Especially considering we have long since been living in the era of nuclear non proliferation, there’s really only benefits that a shift to thorium reactors offers. If we shifted all our fission reactors to thorium we would blast past China in the technological arms race they’ve steadily been gaining momentum within. If we switched to thorium the US could completely shift away from fossil fuels and become totally energy independent of the Middle East and oil.

    SALT I and SALT II the strategic arms limitation talks of the 1980s invited the scientists who worked on the chemical weapon manufacture treaty to participate in the talks. The negotiations ended with the nuclear nonproliferation treaty. This Treaty was an end to nuclear technology in usa and the ussr. We agreed to stop all nuclear weapon development and nuclear power plant building. We do not share nuclear technology develop or build nuclear technology. We have built edison generators and dynamos to replace nuclear and fossil fuels but we agreed to an end to nuclear technology..

    Solar energy works because of the sun. The sun works because of fusion. Lets make a sun. We need this product. We need fusion, not fission. Fusion has no radioactive by products as fission does. Fusion produces many times the power fission does. We have fission already (nuclear power plants), we need fusion.

    6:32 'the fuel is plentyful' is a false claim (or blatant lie). The currently proposed fusion reaction involves Tritium and Deuterium, both hydrogen isotopes. Whilst Deuterium is indeed plentiful, Tritium is not. Tritium is highly radioactive and has a half-life of 21y. It therefore does - for all practical intents and purposes - not occur in nature. Currently it has to be produced through nuclear fission. Another proposed - but by far not proven - way of Tritium production is the breeding of Tritium inside the fusion reactor. However the proposed reaction chain requires one Tritium atom to fuse in order to breed a new Tritium atom, which - considering the necessarily occurring losses - cannot lead to a self-sustained Tritium supply. There are ways to increase the Tritium production, for example through neutron multipliers, such as Beryllium, but Beryllium is rare, so by far not 'plentiful', and thus puts a cap on the availability of fusion fuel.

      @Nicholas Negron Whether Helium 3 is plentiful will still need to be proven, not to mention the economic viability of retrieving it. But it doesn't change the fact that Tritium is practically absent.

    When you already have a natural fusion reactor (Sun), why try to build another? It may also be dangerous. Harness the power of the sun through solar panels as much as possible.

    The quickest solution is solar on the roof s and batteries in home. Every time one of these shows run they talk about the biggest thing they can build massive this massive that when all they really need to do is put it on people's roofs and you eliminate them from the power grid.

      @Robert Martin Well I guess in some cities/parts of the world, the solar could work efficiently. I still think going forward we would need alternative sources. I'm from India where there's basically no space for detached houses, even though they have ample of sunlight and I'm currently residing in Canada, where we get reliable sunlight for about 2 months. So I see what you are saying and maybe it could work for some cities i guess but like that's about it

      @GKast Official I'm well aware of that but in the United States a lot of the country is empty rooftops All this sounds like to me is a business trying to make money off people we're going to need something big and that's not what the case is. Start out by putting solar on roofs and doing lateral power where I can sell my power to my neighbor quit this big business for everybody thing. I also watch several of these videos where the thing starts out with this discredit solar discredit wind but that's what we're using right now. I'm completely off the grid I rely on nobody.

A primary water circuit transfers heat generated from nuclear fission in the fuel to a steam generator; this water is kept under pressure so it does not boil."
