I really enjoyed the documentary. I retired from Helion in July of 2021, now I can show my family what I did for a living. I worked on FRC plasma machines for 35 years altogether. It’s good to see all the hard work come to fruition at Helion. My one disappointment with the footage is you didn’t show much of the puff fill system. That was my big contribution. I imagine I’m the only one that would get a thrill from a bunch of valves and stainless steel tubing.

I'm just as amazed by the cable management outside the nuclear reactor.

The current major failing of Helion is that they have yet to turn their device vertical and start referring to it as a warp core.

Thanks for visiting, Brian. As always, we appreciate your ability to breakdown complex engineering topics - including direct energy recovery from fusion!

The timing of these two videos were immaculate

I love the fact that it generates electricity directly from the reaction, it always feels weird to go through all this cutting edge technology just to build a stream engine!

I can't imagine the theory of "this should work on paper" to actually going and building it and making fusion reactions. Mad genius scientists!

"In this machine is a delicate orchestra of electronics pushing two plasma rings into a violent collision, and catching that collision in a magnetic trap in the center, which proceeds to shrink until the ions trapped within it have nowhere else to go but to fuse, overcoming one of the universe's strongest forces to create new elements in the belly of a man-made machine." Dude, this gave me goosebumps

8:30 can we acknowledge that he just held a flawless and calm monologue explaining such a complex topic perfectly and very easy to understand without a pause or a hick-up.. not even an "uhmm"

I feel so lucky to live in a time where this information is not only readily available, but there are people like you out here breaking this information down into bite sized pieces that are easier to understand. Thank you for all the hard work you do.

My mind is completely blown. As a studying engineer, seeing this crazy amount of engineering going on that I wasn't even aware of blew me away, I'm super excited to see where this project goes in the future.

Despite how depressing some aspects of modern humanity can be, the sheer scale of the technological growth we’ve achieved is incredible.

4:24 as an engineer, no matter how sophisticated and groundbreaking the design there's always room for zip ties.

Here are some problems that's not mentioned in this video. 1 D-He3 is much less reactive than D-T, depending on the temperature it can be anywahere between 10 to 1000 of times less reactive than D-T which means less fusion for the same input energy. 2 The D-He3 mix will sometimes fuse D-D into He3 + N so they still have to deal with neutron radiation like all other reactors. 3 Another problem is something called Bremsstrahlung which will radiate away alot of energy that won't be captured by their electric field.

This is the first description of a fusion reactor I have seen that seems like it could really work. Eliminating the heat/steam/turbine steps is huge. Slamming two rings of fusion material together rather than trying to just heat a kernel of material is also genius. Having a system to actually produce fuel on a realistic scale – you guys are just on your toes. This is not just some breakthrough but many breakthroughs. Great job Helion! Good luck as you move forward.

Amazing machine. Using the magnetic confinement to resist the expanding fusion reaction in order to get usable electricity is pure genius.

Ive never seen something so unbelievably beyond my realm of possible understanding explained in such an incredibly understandable way. Awesome video

The main reason there isn’t much beryllium production isn’t because it is rare or because it is hard to extract, it is because there isn’t much demand for it. There are a lot of mines which have to design their processes carefully so they don’t have to go through extra steps to get beryllium out of their products. If there was a market for it it would be worth reducing the beryllium and extracting it.

Thank you to all the scientists working on this night and day. This is truly one of the most important advancements in the 21st century.

The thing that still blows my mind about fusion reactors is just how damn hot the fuel is! I know that it's being manipulated by magnetic fields to keep away from the walls of the chamber, etc, but it just still seems so crazy and amazing that that's enough to control such a high amount of energy. When he said that the electromagnetic pressure gets it up to 100 million degrees to initiate fusion, I was flabbergasted and still am.
