The rare earth oxide then undergoes a molten-salt electrolysis process that converts it into a solid metal form. We found that existing water infrastructure is a massive overlooked real estate segment that is ripe for renewable energy development,” says Emily Morris, CEO and founder of Emrgy.

This has radically improved what can be done with high-voltage transmission lines, MRIs, and energy storage. The engineering challenge of building complex systems that can harvest the energy and convert it to electricity without being destroyed by radiation poses a series of tall engineering and materials-science hurdles.
