This pistonless engine runs on hydrogen and revs to 25k rpm

Its called the Omega 1 and it is a rotary engine with no seals, barely any moving parts, and almost no losses in the combustion cycle. With a traditional internal combustion engine you lose stacks of energy through heat and friction, well with this new engine by Astron Aerospace. They aim to eliminate nearly all the losses associated with internal combustion. #omega1 #rotary #pistonless
