https://newatlas.com/outdoors/arc-turbine-microgenerator/ "diesel, kerosene or jet fuel, with 5 percent turbo oil... extreme power density to create an ultra-portable generator that packs an 8-kW punch. The ARC microturbine generator measures about 17 x 27 x 52 cm (6.7 x 10.6 x 20.5 inches) and weighs just under 9 kg (19.8 lb). For reference, a petrol-powered machine like the Gensafe GF8000 weighs 107 kg (236 lb) and uses a 459 cc engine, although to be fair it's got an inverter built in as well, where the ARC microturbine requires you to buy one separately"
