AI Technical Summary

Technical Problem

Existing wind power generation devices rely too heavily on natural wind speed, resulting in unstable power generation efficiency, making it difficult to operate in complex terrain or light wind environments. Furthermore, they fail to effectively utilize ground effect pressure differences and solar thermal energy, limiting their application in diverse low-altitude scenarios.

Method used

A ground-effect temperature difference-driven magnetohydrodynamic (MHD) wind power device was designed. By combining a spiral guide tower and a wind aid with a MHD control module, the wind power device is driven by the air pressure difference between the ground surface and the upper atmosphere and the solar temperature difference. The speed is stabilized through the MHD control module, and a high-efficiency electrical conversion system is integrated.

Benefits of technology

It can still start up and generate electricity effectively under low wind speed or weak light conditions, which improves the operational stability and energy utilization efficiency of the device, avoids the impact load of mechanical braking, and realizes the integration of power generation, regulation, energy storage and power supply.
