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.
There are two grades of helium wells in terms of purity. Medical and kids' parties.. so that's why it's is still used for balloons.
