The way to gen set prime mover economy is two-fold both offset by trade-offs and compromises.
3,600 RPM is awful. Two pole generators suck for economy. 1,800 RPM is more common. Fuel economy improves 5-8%. A six pole 12-turn gen set is the best. 1,200 RPM but horribly big and heavy. 12-turn is ideal for long run times.
Coolant versus air makes a huge difference in economy. This is why VW was forced to change. Efficiency was so poor emissions could not be controlled. Today's water cooled cars could haul a beetle on their roof, pass another going uphill and get better fuel economy doing it all the while.
A water-cooled direct injection Honda 2000 would use about 65% of the fuel of a standard Honda.
