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

Did NOT expect the narrator to be Admiral Jean-Luc Picard but let me tell you that made this video 100x better.

By the time ITER has first fusion (in 2035), all the technology they’re using will be decades out of date… ITER was designed in the 1990s!!

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.

Jean Luc !.....cheers.

I’ll believe it when I see it.

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

Well at least some people are doing something instead of just protesting

Well done 👍

Again, simply Wow. 💜

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

I think Temu have one for $57.

That's hot Kelvin, and it spins plasma* a bright halo 😇

Even if it doesnt make energy, its kinda make auroras .. and thats beautiful

Of course, we are still decades away from fusion power.

Gotta love Sir Patrick Stewart 🙂

can you build a reactor in space and use it up there or would you need a constant fuel supple to keep it working...................

This is truly amazing

Hey kids the old joke still rings for generation Fusion is ALWAYS 5 years away!

maybe that's it - fusion reactors have to be gigantic to work and we'll miniaturise them again later.

But unlike what happens in solar fusion—which uses ordinary hydrogen—Earth-bound fusion reactors that burn neutron-rich isotopes have byproducts that are anything but harmless: Energetic neutron streams comprise 80 percent of the fusion energy output of deuterium-tritium reactions and 35 percent of deuterium-deuterium reactions. Now, an energy source consisting of 80 percent energetic neutron streams may be the perfect neutron source, but it’s truly bizarre that it would ever be hailed as the ideal electrical energy source. In fact, these neutron streams lead directly to four regrettable problems with nuclear energy: radiation damage to structures; radioactive waste; the need for biological shielding; and the potential for the production of weapons-grade plutonium 239—thus adding to the threat of nuclear weapons proliferation, not lessening it, as fusion proponents would have it. Bombardment by fusion neutrons knocks atoms out of their structural positions while making them radioactive and weakening the structure, which must be replaced periodically. This results in huge masses of highly radioactive material that must eventually be transported offsite for burial. Many non-structural components inside the reaction vessel and in the blanket will also become highly radioactive by neutron activation. While the radioactivity level per kilogram of waste would be much smaller than for fission-reactor wastes, the volume and mass of wastes would be many times larger. What’s more, some of the radiation damage and production of radioactive waste is incurred to no end, because a proportion of the fusion power is generated solely to offset the irreducible on-site power drains.
