You could potentially use a turbine engine as a generator in a hydrocarbon-electric setup. It would in theory be lighter, simpler, and require less maintenance.

For now there's already a lot of momentum with ICE and they are very polished products. But I think the potential for turbine is there given the shift towards electrification.

Some hurdles include working with materials that can tolerate very high stress, and finding ways to improve efficiency from significant heat loss.
