SCIENTISTS have managed to divert lightning strikes using a giant laser for the first time.
They say the technique could save power stations, airports, launchpads and other buildings from damage.
The trillion-watt laser creates a virtual lightning rod — metal conductors that intercept flashes and guide their currents into the ground.
The laser beam heats air molecules to create a channel that act as a “filament” that conducts electricity.
The five-ton device, the size of a large car, was installed near a 400ft telecommunications tower in the Swiss Alps which is struck by lightning 100 times a year.
Scientists saw the laser divert the course of four lightning discharges by up to 150ft each time.
Dr Clemens Herkommer, of Trumpf Scientific Lasers in Unterfohring, Germany, said: “By shooting a thousand laser pulses a second into the clouds, we can safely discharge the lightning and make the world a little bit safer.”
A small portable laser could detect signs of alien life, scientists say.
Boffins at the University of Maryland shrank existing tech to make a device weighing 17lb for space missions.
