The Kalina cycle, developed by Alexander Kalina, is a thermodynamic process for converting thermal energy into usable mechanical power. It uses a solution of 2 fluids with different boiling points for its working fluid.
Illustrated diagram of a closed-cycle gas-core nuclear-thermal rocket ("nuclear lightbulb"). A nuclear lightbulb is a hypothetical type of spacecraft engine using a gaseous fission reactor to achieve nuclear propulsion. Specifically it would be a type of gas core reactor rocket that uses a quartz wall to separate nuclear fuel from coolant ...
