Bottling A Star: Is Fusion Energy An Unlimited Power Source?

It is the greatest technological challenge ever undertaken by humankind. Fusion - the aim to produce the ultimate unlimited environmentally friendly energy solution. The challenges, at times, seem overwhelming, and it has been dubbed 'bottling a star'. So far the goal of producing a working fusion reactor has remained elusive and out of reach, but we may now be almost there.

    Did NOT expect the narrator to be Admiral Jean-Luc Picard but let me tell you that made this video 100x better.
  • Nicely done, but someone gave you some bum advice about sourcing tritium currently: it is NOT extracted from spent fuel. There is no reasons to find tritium there; it is "bred" in heavy water by neutrons. Our CANDU reactors in Canada produce it in relatively large amounts as the systems require low cross section moderators like D2O to work. It sits in the reactor calandria and the cooling channels holding the fuel. best regards, DKB

    Well at least some people are doing something instead of just protesting
  • Engineers seriously don’t get enough credit for what they have achieved in such a short time
  • I have listened to this for many years and slowly we are getting there. To be able to create 2 watts of power by using 1 watts will be the turning point in the future of humanity simply by stopping us being held to ransom over the cost of energy. I understand that it won’t be in my lifetime But for our children and grandchildren this will be their saviour and the saviour of this beautiful planet we will be on our way to a sustainable world.

    I know the joke is, fusion is always 10 years away... But it's almost unfathomable what is actually needed to even get to the point they are at now... This documentary paints a broad picture I think. All the work being done and has been done deserved immense praise

    By the time ITER has first fusion (in 2035), all the technology they’re using will be decades out of date… ITER was designed in the 1990s!!
  • The idea of ITER is to maximize one of the 3 crucial variables, containment time. By building an extremely large toroid, the cross-sectional area of a traditional fusion toroid is increased, which, in turn, should increase the duration of the fusion containment time. Unfortunately, the powerful magnetic containment fields inherently "leak." However, if you can get the magnetic fields to have a large enough cross-sectional area, then you might be able to sufficiently increase the amount of "fusing" that takes place PRIOR to the moment when the particles ultimately "leak out" through the "leaky" sides of the powerful magnetic fields. Again, this is why the ITER construct is so physically huge.
  • Harmonic pressure vibrations.. Does anyone remember the sand on the harmonic plate? What if we could make opposing pressure waves within the chamber to help force the particles into constructive patterns? Could that help at least force them closer? Part of a solution perhaps? If we placed strategic in and outlets along the donut, we could make that possible. Or perhaps another form constructive interference.

    I’ll believe it when I see it.

    I knew it was Sir Patrick Stewart! I was like, "I know that voice…." Then it hit me!
  • "Hey, ROCK! watch me pull a rabbit out of my HAT!" "again?? but that trick NEVER works!" "This time for th-ure! nuthin' up muh sleeve... PRESTO!!"
  • So here everyone from all over the world comes to work together while the rest of the planet is busy hating on each other. Baffling
  • My Gues is that while we all watch the big machines, someone is much closer to a micro-machined functional reactor on a shoestring budget.
  • The really interesting thing about fusion is that you are trying to release energy that was stored all the way back to the time of the Big Bang, when only Hydrogen and Helium were present.

    I clicked through this documentary to see if any part of it had NO MUSIC. I failed. Now on a quest to find a good documentary where the narration alone is sufficient. "You fool" I hear you say, "Don't be a Don Quixote - why does it matter, who cares? Even watching paint dry is improved with a bit of Wagner" But I must see it through to the end, good citizens of Youtubia.
