You could lug around a Honda generator itself.
However, we must think beyond Petrol and Diesel. What about plant based fuels, or high blended ones, where the engine can be optimized for constant torque, high efficiency operation.
Current ICE's are optimized for a certain set of assumptions, you know, to drive a vehicle.
A generator, expected to produce a constant current and voltage, can be optimally designed.
Having said that, say you have a generator with you in your EV. You are lugging around the weight, and the power cycle efficiency is reduced due to introduction of electrical energy conversion.
However, again, it serves well to have a tiny generator, that can charge up the vehicle to drive 50 or so miles, enough for emergencies.

- h2odragon 4y agoOptimising engines for generator type use works no matter the fuel. In fact it makes them easier to adapt to a range of fuels, i think. I'm still a fan of ethanol fuel: all the "its so bad" press uses transparent trickery in their arguments like considering the brewers grains waste instead of value added feed; and so on. The "we can use it now" advantages outweigh a lot when pinch comes to shove. That we can produce ethanol locally and small scale is I suspect the biggest reason it fell out of favor.
