As I understand it, "cold fusion" doesn't necessarily mean room temperature. That would actually be quite useless. Cold fusion could mean anything from "doesn't need millions of degrees" to "cool enough to directly hook up to boilers to power steam turbines" (and potentially a lower pressure requirement). The "room temperature" thing is mostly due to bad "science" and frauds (though it is still questionable if higher temperature cold fusion can be a thing, too). It's easier to cheaply make an alleged "cold fusion device" if you don't have to heat it up to or contain it at up to several thousand degrees.

Isn't there actually quite a lot of funding available for uncontrolled hot fusion? https://www.icanw.org/squandered_2021_global_nuclear_weapons_spending_report ;) 162.158.38.32 23:29, 5 July 2023 (UTC)
Note that controlled hot fusion (e. g. a functioning Tokamak) would also be really valuable. Nitpicking (talk) 02:17, 6 July 2023 (UTC)
Someone explain why superconductors are a big deal
Arguably the temperature has to change for a semiconductor to work. For it to work at room temperature alone would be pure magic.
A note about the fusion connection. In recent years, there have been breakthroughs in high temperature superconductors, which theoretically would allow to build controlled hot fusion reactors at a much smaller scale (because they can create much higher magnetic fields). There are seveal private companies that attempt to do that, most notably CFS with their SPARC Tokamak. I think this is what is being referenced here. --172.71.160.54 08:16, 6 July 2023 (UTC)
- Maybe you could add that yourself? I wrote the current explanation but actually have no expertise in that area, and also I'm not sure how to incorporate that into the current flow of the explanation. Rebekka (talk) 09:01, 6 July 2023 (UTC)
- I assumed the title text (which says "demonstrates" and not "produces" uncontrolled fusion) - could be as simple as a device proving the sun is a fusion reaction --Nico (talk) 11:49, 6 July 2023 (UTC)
- It could also be that he does have a device that produces uncontrolled hot fusion, and they won't fund it because the government does not negotiate with terrorists. 172.69.247.40 11:56, 6 July 2023 (UTC)
