> if you are going to play you are fine

I manage a fleet of off-road vehicles at work, and just came back from a camp location we were operating out of a wood clearing with no mains. We pack in our own generators and fuel for these periods where we can't access the grid, which could be used for charging.

It would be cool if they built a car with a generator in it so you wouldn't need to fill up the generator and then the generator charges the car. You could just put gas in the car!

That’s actually already how the diesel-electric drive-train of a railway locomotive works - and coupled with a battery it would give the best of all combinations. Only downside is permanently lugging around the generator. This is what they’re looking at for some military vehicles.
