Battery life is always a problem when it comes to drones. The main goal of a drone is to fly as long as possible. That way, it can do its tasks without having to land and recharge. The recharging process often takes hours at a time, leaving a large gaping hole in the drone’s schedule. An idea circulating around in recent months is using laser beams to recharge drones while they are flying. While that sounds like something straight out of a science fiction novel, it is closer to reality than you may think.
Military and private companies have tried various methods into recharging drones using laser. One method involves targeting energy panels on drones with concentrated laser, recharging its battery in the process. This creates zero down time, which keeps the drone in the air longer, if not indefinitely for the duration of the task. In theory, a drone can receive charges via lasers through a network, giving it the power source to continuously travel at a large area.
Diamond Laser Recharging
The company LakeDiamond from Switzerland may have created a new branch in this division of charging. Using lab-grown diamonds, they created a laser beam that can, in theory, provide unlimited charges to drones. And yes, this sounds like something a villain from a James Bond movie would create, but hey, apparently it works!
The laser points to the drone’s panels, recharging the battery while in flight. This eliminates the need to further increase the battery size of the drone, or any other alteration in the drone itself. All they would need is a decent range from the diamond laser and they are all set. While this is a great idea, the creators still urge the use of backup power and not rely on the laser system completely.
Will this be the ultimate solution to the battery problem that has plagued drones since its inception?
