Yes, w/o plug-in, hybrids are useless except in buses, taxi-cabs,
trash trucks.
Does anyone know why the engine that charges the batteries couldn't
be a turbine instead of ICE? Since it doesn't need to be variable
speed like a directly-powered vehicle, it could be tuned to it's
most energy-efficient RPM, and either be on-or-off.
And after the hot moving gases spin the generator, there's still
lots of energy left in the gases, so they could be used again, to
spin another generator, or maybe a supercharger. Or both.
