Researchers in Switzerland have developed a laser that heats the air over 1,500 degrees Celsius and produces a shock wave to expel the suspended water droplets sideways. This creates a hole a few centimetres wide over the entire thickness of the cloud. The laser beam should be kept on the cloud and the laser that contains the information should be sent at the same time. It then slips into the hole through the cloud and allows the data to be transferred. This “laser cleaner” is currently being tested on artificial clouds that are 50 cm thick but that contain 10,000 times more water per cm3 than a natural cloud—and it works, even if the cloud is moving… read more.
