Has anyone come across a source of very small petrol ( or LPG) gemerators, around the 200-500w mark?
240,110,24 or 48V output would be useable. There are plenty of ~1KVA inverter types around, but can't find much below that. I need a lightweight power source for an unusual application, and a small gen may have better power/weight than a battery for the power level we need.A petrol strimmer or larger RC aircraft engine with a dynamo might be an option but really don't want to get into building the mechanics unless essential...!
Wondering if LPG from a blowlamp refill or camping canister could be an option for fuel - we need 1 hour runtime at 250w load (which is about 1MJ)
