Space missions already use electric propulsion devices, where electromagnetic fields are utilized to generate the thrust of spacecraft. One such electrodeless device, which harnesses radio frequency (rf) to generate plasma and a magnetic nozzle (MN) to channel and accelerate plasma, has shown immense promise in pushing the boundaries of space travel. But scientists have so far failed to achieve efficient conversion of the rf power to thrust energy. Now, a researcher has achieved a stunning 30% conversion efficiency.
