"Water-Powered Nano Rocket Thruster: Fingertip-Sized Innovation"

Researchers from Imperial College London have developed a nano rocket engine called the ICE-Cube Thruster that runs on water and could be used to maneuver small satellites in space. The engine utilizes electrolysis to split water into hydrogen and oxygen, which are then fed into a combustion chamber and nozzle less than 1mm in length to produce thrust. This eliminates the need for bulky storage tanks, making it easier to miniaturize propulsion systems.
