I already agreed pretty readily with your reservation about the rarely-used part. I still can't escape the idea that, with a little more try, a 10HP generator could be 1/3rd the size. Engines are, yeah, complex; I've tried to & fucked up tending to the carb on my small unit. Anything we can do to get solid state seems like a win- fuel injection, electronic valve control, this neat new ignition capability. Small wins, helping size, hopefully reliability, efficiency. Integrate the motor & generator housings, if we can, use more integrated systems integration. 7kW would still charge at the rate many cars do charge at. Double that & this seems really useful, if it's small & cost effective. I've been not-great at getting to it for a while, but I used to go drive out, & mix car camping & hiking & driving around for a week or two. An EV would be unsuitable, particularly given that hills are an attraction. But an EV with a range extender would be superb. My car could slowly charge over night.
