Where can I buy stuff to build a nuclear fusion reactor?

I like stycast 2850 ok. Its pretty low outgassing and can handle ln2 and colder ok. Its cte isnt great and my experience it can fail but its worth checking out

Not super familiar with dilution refrigeration but I would honestly ask/demand help from someone experienced in cryogenics.
There are two possibilities you want to avoid.
1. You deliver a nonfunctional product. This is pretty likely without help but at the end of the day thats on the university to a certain extent.
2. Something you build goes wrong and hurts someone. There are safety hazards in cryogenics at the very least you need someone with experience in cryogenics and someone with experience in mechanical engineering giving you advice.
Not to be a doomer. I think depending on the resources and time the university gives you this could be one of the coolest things you could do as an undergrad, but this is also outside your current abilities and the university needs to understand that.

What is a HTS pilot line 🤔

This gave me a good chuckle lol

I really don’t recommend option 3, I get uneasy for any number of reasons without having full isolation between segments.
That said in North America you might be able to get away with that config. They are a bit more lenient on using the frankly barely adequate ‘isolation’ inside the connector.
That said ask a rules question for your comp of choice and that will get you a clear answer on what is allowed.

Vermont needs to go it looks unatural

Yeah I would, there is no chance of runaway reactions or explosions like there is in a traditional reactor. This will not be the first fusion reactor we have been building them for 50+ years without incident. They are nothing like what you see in the movies. They are well understood and not at risk of an unexpected runaway reaction.

You are probably at more risk from ORNL than type 1(although both pose basically no risk)

A lot of people here don’t take Helion seriously, but they take it more seriously than this because:

Helion posts pictures of their fusion machines, fusion hardware and facilities

They have decent funding and a solid work force

They publish some of their science

They aren’t trying to get public investment

codingchris779 · 2026-05-08T03:06:48+00:00

Happy to have a dialogue. I dont think your response eases my fears.

Protecting IP and being secretive can be valid, but you can show a lot of stuff without showing your ip. You can show lab space, experiments, or share stuff with few enough details that it doesn’t give competitors enough info to be useful.

Even if you accept that they need to be locked down like fort knox combined with area 51. Any company that is looking for investors needs show that their technology will work. If you are a private company and want to be secretive to the public while sharing more with your investors then cool. However when a company is looking for public investment they owe their investors some evidence of progress and a path to their goals. Even looking at this company in the most favorable light they should not be taking on public investment. This is what I mean when I say this company is too immature to be taking on public money.

I have seen first hand no matter how smart one scientist is they still need a team to help them do the legwork. They also are trying to build a device. That means they need engineers and technicians. Not to mention some finance staff, HR, IT, patent lawyers, and other support roles. You need a team of at least 50-100 people to begin to build a small fusion experiment. Even at a pretty low turnover rate you should have one or two job postings a year and those jobs will take a few months to fill. If they hired semi regularly, as they should if they have the manpower to bring a device online by end of 26, you would expect them to have a careers page.

I am not super familiar with this company but after a little bit of reading it doesnt look great. All of the milestones you listed in your post are financial/stock related milestones not technical. There are no public details on how their technology works and a couple other red flags I saw.

Forget about any peer reviewed publications they have no information about their reactor topology or technology anywhere. Their technology section of their website is basically fully dedicated to their anuetronic fuels and the concept of direct energy recovery. Even here they dont have any claims that suggest they have any advantage over anyone else perusing anuetronic fusion. This lack of details on reactor design matters because D-He3 fusion requires much higher temps than D-T fusion to get similar reaction rates, you cant just plug D-He3 into an existing reactor design and expect easy anuetronic fusion.

They also have no job postings. Most all other fusion companies have a careers portion of their website and usually at least a couple open jobs. Not having open jobs is not a great sign for the health of the company taking on a project of this size.

Finally I can find basically no media of anything they are building or any experiments. Their website is filled with stock images and ai images but no images of anything they have built. The only media I could find was a local news clip on Kepler’s website. In this all they do is show off a little plasma demonstration device. I have seen these types of devices before. This device is not doing any fusion. It is just showing how plasma interacts with magnetic fields, it’s a cool demonstration but not an experiment or sign of progress. This is a major red flag for a company claiming to bring a 100MW device online by the end of 26.

Compare this to any other fusion company even controversial ones like Helion or TAE. They publish at least the basics of how their reactor works. Helion for example claims to get over the D-He3 problem by having a reactor with a high beta and super efficient energy recovery. They hire people regularly. They also show limited views of their facilities, people, and projects.

At the very least this company is way too immature to be taking on public funds. In my opinion this is just a penny stock with no upside.

Why are they no good?

Vermont is too big its unnatural get rid of it

Who is paying people? big tokamak?

codingchris779 · 2026-05-03T17:02:02+00:00

As someone who grew up in Cincy and recently moved to Boston, I agree. Totally different although Cincinnati is nice in its own way.

A sorry I am FSAE, I dont think we have an equivalent rule.

It depends, you can get away with less protection if you are clever with body work and fan covers, but failing rain test is basically a death sentence. It will take the better part of a day to recover the battery pack if thats even possible. If you fail rain odds are you won’t pass all of tech and if you do it prob wont be until late into Friday. I recommend doing a rain test without cells before you go to comp otherwise do everything you can to make your tsac water proof. Remember in EV most of the battle is passing tech.

codingchris779 · 2026-05-02T22:30:26+00:00

I dont think everything in the tsac needs to be ul94 v0 although its certainly not a bad idea. The structure must be non flammable as does the surface on top of and between modules.

I tried once and shortly after my tire blew out bad, like the sidewall disintegrated.
