Escape Dynamics, a start-up in Colorado, recently tested a prototype of their new rocket engine. But instead of launching a rocket powered with typical rocket fuel, they launched it using microwaves by beaming power at the ship from an antennae. The system – which brilliantly incorporates a gyrotron, a power conditioning unit designed to supply highly stable current and voltage, and a modular power supply unit – could make space travel not only more affordable, but it could help save the planet by reducing the chemicals needed to launch into orbit.
