Plasma Jets May One Day Propel Aircraft

Jet planes may perhaps just one working day fly without fossil fuels by utilizing plasma jets, new study from experts in China implies.

A wide range of spacecraft, this kind of as NASA’s Dawn room probe, produce plasma from gases this kind of as xenon for propulsion. Having said that, this kind of thrusters exert only very small propulsive forces, and so can locate use only in outer room, in the absence of air friction.

Now scientists have established a prototype thruster capable of building plasma jets with propulsive forces equivalent to people from conventional jet engines, utilizing only air and electricity.
