Abstract

Provided is a spatial solar energy wireless transmission method based on a laser-induce plasma body. A middle lingering platform is added between a spatial solar power station and a ground receiving device to divide a transmission area into a vacuum transmission area and an air transmission area. Different transmission methods are respectively utilized according to characteristics of different transmission portions, the vacuum area uses an existing laser wireless energy transmission method, and a superstrong and ultrafast physical mechanism is introduced into the air area. A plasma body channel is formed by using a non-linear effect in superstrong and ultrafast laser air transmission, electric energy can be directly transmitted into the ground receiving device, and high-reliability and high-efficiency spatial solar energy transmission can be achieved.

Description
