When you're transferring the same amount of energy in a shorter amount of time, something is getting hotter.
So that will just juice the propellerheads to look further into room-temperature superconductors.
Heating is a function of resistance. When resistance goes to zero, there is no heat gain.
(Of course, like room-temp superconductors, the new battery technology will need to be proven at scale. Don't hold your breath.)
So they'll do what conspiracy theorists in the 1950s said the oil companies had done to the special carburetor that enabled 70 MPG on passenger cars. Buy the patent and bury it forever.
