Discussion and news on advancements in the field of nuclear fusion energy and related technologies.

Nuclear Fusion on Reddit

Focused on advancements in the field of nuclear fusion.

Submissions should be related to nuclear fusion or plasma physics as currently understood by the scientific community.


Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide together at a very high speed and form a new nucleus. For light elements like hydrogen or helium the fused nucleus weights less than the sum of the original nucleus. The missing mass is released as energy in accordance with Einstein's mass-energy equivalence equations. Fusion is the process that powers active or "main sequence" stars.

Advanced Fusion fanatic/out-of-the-box-thinker due to current job as a High Energy Physicist.

Greetings everybody, nice to meet you all.

My direct boss at my lab is one of the leading engineers in the US with regards to fusion energy, newer methods, the initial introduction of AI modeling, etc. All of this had me spending much free time researching what either hasn't been researched in my mind or what blatantly hasn't been researched or is the absolute biggest issue.

Obviously we all know the biggest issues and I don't mean, for example, tritium being of short supply on the planet because there is plenty on the moon besides neutron capture.

I believe I have solved the issue with using beryllium blankets. I believe I have added an extra layer of conductivity based upon a novel approach which once again eliminates beryllium blankets and/or beryllium 100%. Why not use the high energy neutron as opposed to capture it and waste it? If you can follow where I'm going from that one statement right there, I'd love to have a private conversation with you. I have ideas of using LiH/LiD not just for their intended purposes but for their side effects, I'll put it. All of this information that has been posted publicly is already in the hands of those I've questioned, and so far I haven't put anything here that is proprietary. If you'd like to discuss something for the giggles of it or perhaps workshopping, don't hesitate to direct message me or even publicly reply.

I really look forward into exploring these three specific ideas with others who are bathed in fusion experimentation on a daily basis.

Tony Blair Institute: Fusion has HUGE value for the UK economy and they plan to win this race.

This is a great take on fusion. It's not tokamak vrs laser. It is not company vrs company.

Instead, this is our national future, versus your national future.

It's the China's fusion program versus, the UK fusion program, versus the US program, versus ...

Wake Up America: The. Race. Is. On.

Assuming all fusion startups successfully build a device that can supply energy to the grid, which company is the most competitive economically?

By that, I basically mean, which company will have the lowest cost to operate or will profit the most? CFS has a big challenge with acquiring tritium early on, which is a challenge other companies may not face.
