Super cool!
...But helium, so not super scalable, right?
They could make it hydrogen, for extra fun when one fails around all that electricity...
The fact that helium is such a rare, irreplaceable, and scientifically useful material makes it wild to me that we use it to fill kids' party balloons.
Good news, it’s not that rare that that would make a difference. There’s plenty of it, just need different extraction techniques to further up the supply (unfortunately, that’s fracking lately iirc)
