# Laser Power in the Sky: Chinese Scientists Test Wireless Charging System for Drones

Unmanned Aerial Vehicle (UAV) engineering is on the verge of a breakthrough capable of fundamentally changing the concept of flight duration. A group of researchers from the Civil Aviation University of China (CAUC) has presented an experimental technology that allows electricity to be transmitted to drones via a laser beam directly in mid-air.

### Double Efficiency: From Laser to Electricity

The key element of the new system is an ultra-thin receiver mounted under the aircraft's wing. The device is constructed using an innovative two-layer scheme designed to maximize energy utilization:

    - **Perovskite Layer:** The upper element is responsible for the direct conversion of laser radiation energy into electric current.

    - **Thermoelectric Generator:** Located beneath the first layer, this module captures the heat generated during operation and converts it into additional energy.

This approach allows for power to be drawn from an external source while effectively recycling the byproducts of the system's operation.

### Fighting Overheating in Flight

One of the main engineering challenges during development was solving the thermal management problem. During tests, the receiver temperature reached critical levels of 80–90 °C. To prevent overheating and equipment failure, the developers implemented a comprehensive solution:

Special nanocrystals that reduce heat transfer were incorporated into the design, and air channels were integrated directly into the wing profile. The oncoming airflow during flight naturally cools the system, which, paradoxically, further increases the efficiency of the thermoelectric layer.

### Test Results and Prospects

Laboratory tests demonstrated impressive figures: the efficiency of converting laser energy into electricity reached 38.49%. The power obtained was sufficient to fully power a propeller model, confirming the viability of the concept.

At present, the technology remains at the experimental development stage. The next step for scientists will be to conduct tests on real drones in open space, which will allow them to assess the system's potential for creating drones with practically unlimited autonomous flight time.
