I did the math on this once a few years ago and used the generators in the northern tool catalog as reference Cheap gas, honda gas and the kubota diesel of that time. Turns out fuel economy was between 20-40 mpg depending on generator used.

Similar to a diesel locomotive, or a Chevy Volt without the battery pack and a diesel engine instead of gasoline. My thinking is that since the transmission and drive motors are electric, you could run the diesel engine at it's best BSFC rpm all or most of the time and just vary the load rather than rpm.

Does anyone see any problems with this idea? Does it seem feasible? Has this been tried before (and met with miserable failure)?
