This new jet engine uses plasma. Plasma is the fourth state of matter, after solid liquid, and gas. It already exists on the surface of the sun and in lightning, but humans can also create it.

A 1-kilogram steel ball can maintain flight as the plasma expands rapidly from the extremely hot ionization chamber environment. The thrust produced matches jet engine performance, which illustrates ...

demonstrating thrust comparable to conventional jet engines. Tang’s approach differs from other plasma propulsion systems, such as those used by NASA. For example, NASA’s xenon-based plasma ...

When [Jay Bowles] demoed his first-generation ion thruster on Plasma Channel ... more like a miniature jet engine than anything that had come before it. Optimizations would need to be made ...

In this process, a jet of plasma or ionized gas is ejected at high speeds, which melts and subsequently removes unwanted parts of materials from electrically conductive workpieces such as metals.

Power mechanics students at Jefferson County Joint Vocational School got revved up after constructing a jet engine model in ...
