Slow-Turning 5 kW Yanmar Diesel Generator

Using THAT generator he would get 88mpg driving down the road off the genset.
Lest anyone accuse me of being a hotrodder or that MY head is the one in the clouds, much of my distaste for this is because it is %100 series, downsizing the engine doesn't change that.

That generator has a 10hp (7.46kw) engine on it to make 5kw electrical.

So if, for example, that engine were directly clutched to an appropriate sprocket and chain to a wheel, the same vehicle could cruise at like 160mpg all day vs 88.

assuming %85 motor/controller efficiency, which is generous, and the %67 mechanical->electrical conversion of the genset (given).

Clutch in a motor in parallel, do some more maths and research bro, I'm out.
