Top Comments of this video!! :3
I'm almost completely but not quite cynical when it comes to fusion that I invariably ban channels talking about fusion especially ones that invoke the words 'breakthrough' and 'milestone.' Those channels immediately get the 'Do not recommend' treatment.
This channel was almost one of those but after fast forwarding through the first 3 or 4 mins I'm glad I watched.
I was expecting sensational platitudes, lies, damn lies, outrageously ambitious timelines, clickbait etc; however none were forthcoming. How refreshing!
My reward? Facts, a potential solution to the helium 3 problem and a plain admission that "turning fusion power into a cost effective real world technology is going to be a long road." Interesting.
It was a good vid this one.

Based on my knowledge, I donât actually think we are gonna end up with fusion power on a huge scale any time soon, but there is still hope. Look at our progress with tech in the last 20 years, thatâs a short time to go from such low tech to a future we couldnât imagine long ago. I may not know much about technology and engineering, but I sure do love learning about it!

There are several innovations here. The reaction is unique for the fusion industry (but difficult to hit temperature); the conversion method is unique (though Lockheed explored this approach). The use of fused silica in a fusion reactor is innovative. We have only seen a few teams use glass inside their reactors; Sam Cohen's team at Princeton is one example. Glass is an electrical insulator; which reduces conduction losses out of the plasma. Almost all fusion reactor vacuum chambers have to be made using metal walls because of vacuum conditions; but the issue is that the metal conducts the plasma away; leading to large losses of energy.

Helionâs design is a first in more ways than one. Besides fusion itself, the most interesting aspect is that unlike all other fossil fuel and nuclear electricity-generating schemes, it doesnât work by heating up water into steam which then turns a turbine to generate electricity. Instead electricity is created directly by manipulating the plasmaâs magnetic field to drive a current through wires. Thatâs amazing. Itâs way past time humanity moved beyond steam-powered turbines.

I am so impressed with the concept Helion is exploiting. I am not a scientist but from what i as a novice could glean they seem to be a front runner in getting to the all important ignition and commercial viability. I wish them well in this quest and wish them great rewards both financially and spiritually for their industriousness and dedication.

This video discusses what other Helion based videos do not: a) their process is aneutronic, and b) why being aneutronic is so important, not only for limiting the neutron-caused degradation of the container walls and making them radioactive, but that there is substantially more energy available with aneutronic fusion. Very exciting stuff!!!

Fascinating concept essentially taking two plasma railguns and aiming them at each other. A huge plus of this approach appears to be taking out the middleman and the wasteful process of translating thermal energy into electrical energy and going straight to electrical energy. As a scientist but in another field besides physics let me add to what the nuclear engineer said. This does look very promising but like everything else in science, the gap between breakthrough concept and viable technology using that concept is huge and oftentimes involves solving technological problems that can take many years, if not many decades. We'll just have to wait and see whether it's promise is realized or whether it turns out to be another seductive dead-end. Science is littered with the Tombstones of such highly promising approaches.

I've been an engineer on one of the biggest laser driven inertial confinement fusion reactors for a couple decades now and I'll be blunt, the vast majority of fusion hype videos on the internet, or anywhere really, are hot garbage not at all worth my time. This video really impressed me though, both in its accuracy and detail, and its relative thoroughness in examination of the RFC scheme for magnetically confined fusion. The sources and citations are quality đ. Compliments do not come easily or frequently from me, but this video does deserve them. I will subscribe in hopes that the current rigorous heavy science focus isn't lost over time in favor more lazy clickbait trash as I've seen so many other channels unfortunately fall prey to.
