CONTINUITY: Energy Storage in Electronically Excited Solid Helium
A short @NASAJPL paper discussing energy storage in 'electronically excited solid helium': https://t.co/BTSeweIwNn

A metastable state of helium can last for 10,000 seconds and store '20 eV', which I think means 482 MJ/kg. pic.twitter.com/SiGZfalBnO
The JPL Technical Memorandum [PDF] from September 1973 notes that if the stability of the “He IV” phase is demonstrated, it might be possible to induce the phase electrically and trigger the release of the energy from the metastable state.
