Summary #1122

Fossil fuel-free jet propulsion with air plasmas
  • Team of scientists from the Wuhan Institute of Technological Sciences has developed a prototype of a jet engine that uses microwave air plasmas as propulsion.
  • The device generates high-temperature, high-pressure plasma (4th state of matter) using injected air and electricity, so it’s not exactly fossil fuel-free as the article states.
  • The upside is that it doesn’t generate large amounts of carbon emissions, but the device is in very early stages of testing.
  • It could potentially be scaled by building a large array of these devices to power a full-sized jet.
  • So far it successfuly lifted a 1-kilogram steel ball over a 24-mm diameter quartz tube.
