This paper reviews researches on miniature gas turbine generators performed to date in the world. There are 2 approaches to miniaturize gas turbine generators: 1) MEMS-based approach and 2) conventional-machining-based approach. The first approach was proposed by Massachusetts Institute of Technology (MIT) in 1997. A lot of outstanding outputs were produced by MIT, but the MEMS-based coin-sized engine has not been demonstrated to date. This paper discusses main three challenging issues of this type of engine. The second approach was taken by at least several groups including us. The main challenging issues are similar to those of MEMS-based engines. In 2007, our group with collaborators succeeded to operate a juice-can-sized gas turbine engine with a compressor impeller of 16 mm in diameter. This is still the world' smallest class operating gas turbine engine.
