A research team in China has developed a high-power microwave (HPM) weapon driven by four compact and efficient Stirling engines…to drive high-frequency electromagnetic waves that are powerful enough to suppress drones, military aircraft, and even satellites. The weapon system, which can easily fit into a truck, and boasts a significant reduction in energy consumption for generating a strong magnetic field compared with existing technologies. According to the project team’s preliminary tests, it consumes only one-fifth of the energy required by current methods and can operate continuously for four hours without attenuation.
