With newer nuclear reactors that use helium or thorium to contain the temperature (the type that do not need water to regulate reaction)

You can produce plasma from anything and run it through a giant magnet (like in fusion) but with nuclear to generate electricity directly.

Helium is the only element in the periodic table that is non renewable.

idk how accurate this is but i’ve heard a tale, that the military is hoarding all it can and pumping it waaaay underground to store what’s left… but i still keep seeing dollar stores and walmart selling cans and pumping up balloons… i am not familiar with the raw process of capturing/mining helium enough to say anything about it.
