Don't worry, even if all energy humans used was from D+T fusion today it would only create 60% of the helium that we use. Also, helium is so light that it leaves the atmosphere so we really don't have access to much anyway.

- willis936 5y agoIt's most valuable use is as a cryogenic. If you want sub 10K there are very few materials to choose from. The lower the temperature, the higher your critical current is for a given superconductor. The reason HTS are a big deal isn't that you can have a superconductor at liquid nitrogen temperatures, but that you can have a very high field at liquid helium temperatures.
