Laser lightning rod on Swiss mountain 

Wednesday, July 14, 2021 - 4:19pm

A team of researchers installed a laser atop a Swiss mountain to provide a path for lightning to take rather than strike objects on the ground. The Laser Lightning Rod project is in its testing phase now. Practical applications include lightning protection for airports, rocket launchpads and hazardous material storage sites. Host Marco Werman speaks with physicist Jean-Pierre Wolf from the University of Geneva, who helped develop the laser.
