High Q (stored energy per energy loss per cycle) of the cavity produces more stored energy, use up stored for kinetic energy Now Shawyer is saying that an interesting 2nd generation device will be ...

It may not sound very much, less than three ounces, but in space a little thrust goes a long way. Boeing’s advanced XIPS thruster, which fires out Xenon ions at high speed, generates less than a ...

Generating thrust to fly an aircraft using the technology behind ionic air purifiers sounds too good to be true - until now. It has been widely believed that electrohydrodynamic (EHD) thrusters are ...
