For a VTOL two-seater, a 55 kW (74 hp) turbogenerator would weigh 85 kg (187 lb) with fuel for 2.5 h of endurance instead of 1 ton of batteries. A demonstrator ran in 2016-17 and ground-testing began in the second half of 2018 before flight testing in the second half of 2019 and first delivery in the first half of 2020.

The ARC fusion reactor (affordable, robust, compact) is a design for a compact fusion reactor developed by the Massachusetts Institute of Technology (MIT) Plasma Science and Fusion Center (PSFC). ARC aims to achieve an engineering breakeven of three (to produce three times the electricity required to operate the machine).

The ARC-100 is a 100 MWe sodium cooled, fast-flux, pool-type reactor with metallic fuel based on the 30-year successful operation of the Experimental Breeder Reactor II in Idaho. ARC Nuclear is developing this reactor in Canada, in partnership with GE Hitachi Nuclear Energy, with the intent of complementing existing CANDU facilities. [4]
Micro combined heat and power, micro-CHP, μCHP or mCHP is an extension of the idea of cogeneration to the single/multi family home or small office building in the range of up to 50 kW. [1] Usual technologies for the production of heat and power in one common process are e.g. internal combustion engines , micro gas turbines , stirling engines ...
The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto the generator shaft, the oil is forced under pressure between the ring and the shaft; part of the oil flows into the hydrogen side of the generator, another part to the air side.
There are many variants of this engine and it is used in many missiles and UAVs, as listed below. Aside from the known uses listed below, it is widely speculated that Iran illegally purchased many TRI 60 engines from Microturbo to assemble C-802 cruise missiles purchased from China.
