Are you thinking of supercapacitors?
- civilitty 3y agoHe's thinking of superconducting magnetic energy storage: https://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage https://en.wikipedia.org/wiki/Superconducting_magnetic_energ... Currently they're only feasible as high quality power sources for fabs and other industrial uses because of the operating costs of cooling the superconductors.
- jacquesm 3y agoAlso used for grid stabilization.
- entropicdrifter 3y agoSo superconductor supercapacitors
- heisenzombie 3y agoMore like superinductors than supercapacitors - the energy is stored in a magnetic field (inductor) and not an electric field (capacitor)
- dfox 3y agoThere is a theory that with room temperature superconductors you could use an inductor for practical energy storage.
- bananapub 3y agowhat are the practicalities of storing enormous magnetic fields and then collapsing them to draw power? that seems...not obviously a good idea.
- dfox 3y agoWell, exactly. While there is a way of getting some of the stored energy as an controlled power, most of the failure modes of such a thing leads to uncontrolled release of the stored energy, manifested by the whole thing just somewhat instantaneously turning into very hot gas.
