Add enough pressure and you can even get metallic hydrogen, which has been predicted to be a room temperature superconductor.
Not that you'd want to be in any room with that kind of pressure (250k atm).
Not that you'd want to be in any room with that kind of pressure (250k atm).
But if someone can demonstrate how to make and hold solid hydrogen in a configuration where superconduction can be demonstrated at room temperature, then you've clearly gone several steps towards addressing feasibility, and you've demonstrated the existence of potential commercial opportunities.
