LakeDiamond’s system produces a laser beam that can shine directly on the photovoltaic cells on the drone’s surface. Thanks to the diamond, the beam can travel much farther without losing strength and damaging human health.(Copyright LakeDiamond)

Scientists at LakeDiamond, a spin-off company of the Swiss Federal Institute of Technology Lausanne (EPFL), have developed a safe laser beam system that uses small lab-grown diamonds to power small drones instead of relying entirely on a rechargeable battery.
