China revolutionizes aviation with the world’s first plasma jet engine, heralding a new era of eco-friendly technology
Chinese scientists have taken a significant step forward in the development of the aviation industry by unveiling the world’s first plasma jet engine, which holds the potential to dramatically alter aircraft design without harming the environment.
Unlike conventional jet engines, this innovative device does not rely on fossil fuels, hydrogen, or batteries.
Led by Professor Zhau Tan from Wuhan University, the research team has demonstrated an experimental engine that utilizes microwave radiation and plasma physics principles to generate thrust.
The core concept involves compressing atmospheric air and exposing it to microwave frequencies of 2.45 GHz — similar to those used in household microwave ovens — which ionize the gas, stripping electrons from atoms and transforming air into plasma, a high-energy ionized gas capable of producing reactive thrust without fuel combustion.
The prototype can vertically lift a steel ball weighing one kilogram, marking a breakthrough in the field.
Experts estimate that the thrust level is comparable to small commercial jet engines.
This technology could replace traditional internal combustion engines in planes and drones, enabling fully carbon-free flights.
While still in experimental stages, NASA has considered plasma propulsion for space engines, but this is the first attempt to apply such technology within Earth’s atmosphere.
The operation requires a powerful source of energy, which can be derived from renewable sources like solar or wind power.
In the future, these plasma engines may vastly reduce the environmental impact of aviation, paving the way for cleaner, more sustainable air travel.
Although the technology remains under development, initial results are promising, offering hope for eco-friendly aircraft of tomorrow that will greatly diminish aviation’s carbon footprint and redefine flight in the 21st century.
Notably, in the first half of 2025, renewable energy sources produced more electricity than coal for the first time in history, establishing themselves as the largest energy source worldwide—a crucial milestone in the global shift toward clean energy.
