Optimising 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.
