Current EHD thrusters are far less efficient than conventional engines. [16] An MIT researcher noted that ion thrusters have the potential to be far more efficient than conventional jet engines. [17] Unlike pure ion thruster rockets, the electrohydrodynamic principle does not apply in the vacuum of space. [18]
An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms. The ions are then accelerated using electricity to create thrust.
In 2011, NASA partnered with Busek to launch the first hall effect thruster aboard the Tacsat-2 satellite. The thruster was the satellite's main propulsion system. The company launched another hall effect thruster that year. [7] In 2020, research on a plasma jet was published by Wuhan University. [8]
An electrostatic pinwheel, or corona spinner, attached to a small Wimshurst machine (electrostatic generator) is shown stationary and rotating. Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative ...
Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
The gridded ion thruster is a common design for ion thrusters, a highly efficient low-thrust spacecraft propulsion method running on electrical power by using high-voltage grid electrodes to accelerate ions with electrostatic forces.

The NEXT thruster has demonstrated, in ground tests, a total impulse of 17 MN·s; which as of 2010 was the highest total impulse ever demonstrated by an ion thruster. [2] A beam extraction area 1.6 times that of NSTAR allows higher thruster input power while maintaining low voltages and ion current densities, thus maintaining thruster longevity.
