>But why is the electric motor so much better than a combustion motor? Time. Torque is instant. I don't know if I parsed this sentence correctly but what came to mind was grid-storage batteries connected to very large flywheels[1] driven by electric motors. And once the flywheel is spinning, short pulses of energy will keep it rotating at high speed. I think this type of setup could prolong the life of the batteries.
