I’d like a powerplant, tomorrow, not 20 years from now, similar to my '21 RAV4 plug in hybrid car I drive, and love. Use both the gas engine and the battery for takeoff, once in cruise a downsized ICE would do the job, regen a bit on the descent, it’s RELATIVELY feasible today, but it’d no doubt be heavy. I’m not holding my breath for a pure EV plane, best I could do would be a E powered light sailplane (they exist) of foot launched paraglider, to get me up to the soaring ridge behind my house.
