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.

I’m sure this is an idea that’s been floated but surely this would work?

We have hydrogen bombs. Couldn’t we create the smallest thermonuclear bombs we can. Build a containment vessel huge enough to contain the explosion, fill it with water, drop a bomb in every x hours and convert steam into power. Presumably it would be a containment vessel miles across, but that dosen’t seem impossible to build? Does this idea have a name? (Beyond stupid 😅)

Is it good or bad for alphaxiv to twitt the criticisms on fusion paper?

On one hand, there are many fusion startups among which many are fooling the investors. On the other hand, if the fusion community do not standup and speak against these liars, they will feel ambarrassed when others do.

Jobs in Fusion for an Aerospace Engineer

Hi all,

I’ve lurked here for a bit and thought I would post since I’m looking for some advice about jobs.

Being vague for anonymity… I’m an aerospace engineer and have worked in the industry for about 5 + years. I’m currently at a well known private aerospace company you’ve likely heard of and have a fairly important technical role on one of their more ambitious projects. However, I’ve been reconsidering my path lately and thinking about moving to a field which is still cutting edge and technically challenging but would have a more immediate or direct impact on humanity and the planet.

Wondering if any of you who work in fusion have thoughts or advice about moving fields? At this point in life I’m not able to take something like an internship unfortunately, but I understand that entering a new field would probably mean taking a pay cut which is okay. Without going into specifics I have a background in intensive environmental testing, system engineering, space vehicle operations, and a number of specific vehicle subsystems. I’m more of a jack of all trades type but very adaptable, happy to learn, and a strong communicator.

What kind of roles would you recommend I look into within the fusion field? Any specific companies you think I should investigate?

Thank you sincerely for your advice! Please feel free to DM as well if you’d prefer.

Newbie here. Can someone quickly tell me how close we are?

Late 20's, hoping to see this climate change shit solved by the time I die. I work in a nuclear science-related field so am interested in this stuff and believe in the power of engineering to solve big problems.

So, this being said: how close do we think we actually are? Still "always 10 years away" or is it actually coming? Would love any thoughts on the private companies that (seem to be?) making strides!
