Breakthrough In Laser-Based Airborne Charging For Longer Drone Operations
Researchers at the Civil Aviation University of China have developed a lightweight drone receiver that harvests energy from a ground-based laser, combining a perovskite laser cell with a thermoelectric generator. The system, which incorporates nanocrystals as a thermal barrier, converted 38.49% of incoming laser energy into electricity and generated enough power to spin the drone’s propeller. The next step is outdoor flight testing to evaluate performance over distance and at altitude. This breakthrough was reported by an unknown source.
