An international group of scientists has created a laser with which you can learn how to control lightning, changing its trajectory and attracting it to a given place. They reported the discovery in a scientific article posted in the journal Nature Communications.
Researchers at the Australian National University (ANU) and UNSW in Canberra created a “miniature thunderstorm” using a pair of flat parallel plates on which an electrical charge was stored. When it reached the breakdown value, a tiny lightning appeared in a random area of one plate and hit a random area of the second.
Physicists used laser-guided graphene conductive particles in the model. The laser beam heats the air, creating a channel with high conductivity in it, a kind of wire through which the lightning bolt rushes. The laser beam heats up the microparticles and creates a high-flow channel through which an electrical discharge begins to flow. Thus, scientists have found a way to make lightning move in a well-defined direction.
The study authors believe that the discovery will allow precise control of the path of the electrical discharge in the air. Such tamed discharges can be useful both for weather control and in industry or medicine.
Earlier, scientists at the Okinawa Institute of Science and Technology concluded that climate change has intensified hurricanes, which take longer to weaken over land. This can lead to an aggravation of the disastrous consequences.
