Currently existing wireless power transmission solutions include:

1. Microwave power transmission: The use of microwaves to transmit electrical energy to long-distance places.

2. Inductive power transmission: Using the principle of induction, the electric energy is transmitted to a long-distance place through electromagnetic field 

induction between the sending end and the receiving end.

3. Laser Power Delivery: Uses a laser beam to refract in the air to transmit electrical energy to a target location.

Wireless power transmission technology refers to the technology of using radio waves to transmit electric energy. It can transmit electrical energy from the 

power source to the receiving end through radio waves, thus realizing the wireless transmission of electrical energy.

Wireless power transmission technology can realize efficient transmission of electric energy, and can be used for the construction of power lines 

across terrain obstacles, and can also be used for power restoration in disaster areas. In addition, wireless power transmission technology can also

be used for mobile power supply, which can realize the rapid switching of mobile power supply equipment between different regions to meet the 

power demand in different regions and time periods.

In addition, wireless power transmission technology can also be used in the construction of smart grids. It can realize remote monitoring and

control of the grid, monitor the operating status of the grid in real time, and adjust the operating parameters of the grid in real time, thereby 

effectively improving the operating efficiency of the grid.
