By Ashley Strickland, CNNScientists were able to create a virtual lightning rod using a large, powerful laser atop a mountain in Switzerland, successfully diverting the path of lightning strikes. Lightning deflection technology hasn’t changed much since Ben Franklin invented the lightning rod in 1752. Scientists decided to test if a laser beam pointed at the sky could act like one big virtual and movable lightning rod. The Laser Lightning Rod, as it is called by members of the European consortium that developed it, was able to divert four lightning strikes. The Laser Lightning Rod weighs more than 3 tons, is 1.5 meters (4.9 feet) wide and 8 meters (26.2 feet) long.
