I think the promises of fusion are largely empty promises, even if we could achieve break-even (plus a little) most of that energy would be used to keep the fusion going rather than powering said city. So saying only a truck load of material (which in itself is no small feat for tritium) to power a city is a little disingenuous, while a couple truck loads for the city's power may be true, there very well could be that mountain of fuel needed just to make the fusion happen. Like geeze guys, we're going from we can't really do it now to we'll be able to do it with really high efficiency so the output power dwarfs what's needed on the input side

I don't believe in nuclear fusion for energy creation, I think nuclear fission has far more potential. It's really just to heat up water and turn a steam generator, nuclear fusion is just an exciting proposition kind of like recyclable toilet paper. Sure, you could create less waste with recyclable toilet paper, but it also requires a lot of effort to maintain the recyclable toilet paper.
Also, lets make more solar panels and wind turbines.

So, the video doesnt explain what the title implies. CAN we build it I have watched the video, and still have no idea. Thanks for wasting my time, TED.
Dont get me wrong: The video is informative and interesting. But the title is incorrect to say the least. It should be:
The science of Nuclear Fusion, and it's history.

Fusion power works by combining light atomic nuclei, such as hydrogen isotopes, at extremely high temperatures and pressures to release energy. This process replicates the same reactions that power the sun and other stars, producing a clean and abundant source of energy.

Creating a small sun and then harvesting energy from it is a silly idea. Just spend those resources on figuring out how to more efficiently capture energy from the actual sun that’s already there and giving off far more energy than we’d ever need.

What about the radioactive neutron irradiated lithium panels That would classify as hazardous. Nuclear fission is the best way we've got of producing energy. It's only drawback It can't be made scarce by corporations.

Once we have fusion, we don't need anything.
Just personal theory, hopefully Not true, why we aren't able to master fusion since'75 is, what happens to solar, wind, etc companies

Guys just saying, if we can do both fusion and fission on a small scale, could we possibly take atoms, and take em apart and put them back together into other things, and make things

I love that the best way humanity has found to harness energy is to get something so hot that it heats water to produce vapor to move turbines, and we've just changed the source of heat.

Never underestimate man's ability to innovate; if any lesson was learned from our long history is that it can be done given enough time any thing can be realized.

The estimated time to commercially viable fusion reactors is a universal constant, with a value of 30 years - my particle physics professor at university, 30 years ago.

We got all the resources we need, we just aren’t distributing it ethically. Pursuing this idea is as needless as colonizing mars. Pure hubris

We could build an entire galaxy if we want to. We are creators. But we are no God level construction workers that have everything under control.

You sure we wanna put a thing that has the gravity of Jupiter while being the size of a penny, and could burn your hand off in an instant
Yes.

It's still crazy that no matter what the energy source we decide to use is, it all comes down to: boiling water and having steam turn turbines

If we achieve this, wouldn’t this mean that we managed to make a perpetual motion machine because of the extra energy being produced

so without water neither a fusion or fission reactor can generate electricity. then it's important that you create water out of nothing
