Fusion fuel is so energy dense that fusion plants will never produce industrially meaningful amounts of helium.

Well, as long as they can make electricity too cheap to meter, we can get helium from somewhere. Mine it from LNG sources currently untapped due to EROI < 1, or ship it from the goddamn Moon - ultimately, every problem in life (except that of human heart) can be solved with cheap energy.
The mere existence of proof-of-work cryptocurrencies means that it is impossible to ever have electricity that is "too cheap to meter". Any time electricity prices would fall below the price of mining, that creates a market opportunity that will be filled by more mining. Wasted electricity is the product.
I'm shocked there isn't more government regulation about this. You can't ban Bitcoin, but if you make it a massive pain to invest in it and make it difficult to convert between physical currency that would drive down a lot of demand.
I think that's only because electricity is the bottleneck, though. If it was no longer the bottleneck, crypto miners would expand rapidly with more hardware, mining difficulty would increase, and eventually the bottleneck is storage space for all your GPUs, if not the GPUs themselves.
With the trend of orbital launches becoming cheaper, it might be that mining helium off-Tera will be our long term supply. Especially if the alternative is adjusting the amount of protons in an atom.
There are several challenges, not least of which is storage. We have considerable leakage in most of our current helium storage solutions on earth because it’s so light. Our national reserves are literally in underground caverns because it’s better than anything we can build. Space just means any containment system will need to work in a wider range of pressure/temperatures.
There is to my knowledge no reason to assume that complicated physics experiments that heat water to run a steam engine will be much cheaper than fission power plants, unfortunately.
I can't say I agree with the conclusion, but I commend you for the concise and poetic description of what most power plants fundamentally are.
Fusion power that uses steam turbines to convert heat into electricity will be more expensive than solar/wind
Only if we first colonize the Solar System, so land becomes too cheap to meter too.
I think this is why he labelled the comment 'Tongue in cheek'. Thanks for pointing it out explicitly tho, was not aware of this.
Can't they irradiate tanks of H2 or something with so much neutrons and electrons until morale improves and they become He? Or would that make radioactive He?
