Great video, thank you for the speakers.

Very informative indeed. Thumbs up

Excellent presenation!

Yet again an amazing presentation. Thank you for making these available to all of us.

Thank you - great talk.

Wow.... I'm old enough to remember back in the sixties when this was virtually a dream.

Great to know the latest work that is going on at JET, ITER and NIF. The FRC approach that Helion Energy in the US is pursuing with its 7th generation Polaris reactor is also very exciting.

If they can get that projectile and energy food that ignites then we could have a machine use fluidlike dynamics to predict the flow and maybe use multiple explosions in an order in dynamics and instead of cancel waves, build bigger energy waves. Like when you push a swing while it’s swinging to give it more energy or slow it down. A series of explosions detonated by projectile and then using the dynamics to carry the chain reaction or something. Magnetic fields can help guide and circulate the flow maybe.

Looking forward to watching to see if there is serious merit, requiring a discussion on rhe quantum mechanics of fusion, referencing the low power requirements of the quantum fusion experiments.

Perhaps the IR from condensing steam could be another source of energy to feed back into the system

An outstanding presentation. Thank-you to all involved!

Great presentation and an encouraging perspective. It occurred to me however that wouldn't it be goodie the energy released could be converted directly to electrical energy without having to suffer the inefficiency of the heat/steam/rotational cycle. Is there any research in this direction (I'm imagining of some kind of plasma electric process analogous to the photoelectric effect) or is this too far fetched?

10:25 where's the chart for the sustained 1 minute operation?

I know this is all groundbreaking science. All of these will provide us with valuable information. It does seem typical that the American version of fusion is basically bigger explosions with lasers.

Wonderful presentations! Thank you for the updates.

There are still many steps that have to be taken, and problems solved, to get to practical fusion power. Many talk about getting to higher Q values, but even a Q value of 1000 would not matter if the reactor costs too much to build, or keeps having to be re-built because the plasma destroys the materials. If we get to reactors that work, at all, in the next 10 years, look to many, many more years before the technology matures to be both reliable and economical against other energy sources that exist now, and are expected to become ever lower cost in the next 20 years.

On inertial fusion, one thing needs to be made clear again: so far, the energy input of the entire machine is still much higher than the fusion yield, only the energy that arrives directly at the pellet to be ignited is lower than the yield! Therefore, the energy yield must be at least 15 times as high as the energy that reaches the pellet. Also, tritium must still be used in inertial fusion, which must first be bred from lithium in a nuclear reactor and is extremely expensive. Per ignition, and 1-10 per second are needed for operation, costs of 100K to 1M dollars must currently be expected. A stellarator will certainly run without tritium as fuel, possibly also without deuterium.

Once fusion is available, how do we disipate the waste heat? Use fusion to scrub greenhouse gasses?

Great talk with really incredible speakers! They did an amazing job breaking down the achievements and what they are working on so even non technical people can grasp what fusion is, and why it's important for the future of humanity.
