20hp is about 15kW. My EV consumes at least twice that at highway speeds. Adding that to my EV would let me drive as far as I wanted to in a day in the extreme case, but would be a nice range extender, and assuming it could run and charge while the car was parked, would let me take it on trips to places that are too far to round trip on a single charge and don’t have L3 chargers. I don’t know how many such places exist for most people, but there’s a few of them near me because I live in a very rural area.
