Submission + - Smallest gas turbine engine in the world 1
SK writes: "A gas turbine engine measuring 10 cm in diameter and 15 cm in length, small enough to hold in one hand has been developed by a study group led by Tohoku University, Japan. The group succeeded in running such a small gas turbine engine and demonstrated the complete cycle for the first time in the world. The study group is working toward practical use of such a gas turbine engine as power sources of autonomous robots for disaster rescue and relief, and personal transportation vehicles indispensable in the aged (Japanese) society."
