Lasers and lightning!
Engineers at Picatinny Arsenal, the US Army's weapons research and development facility, have successfully tested their prototype lightning gun. Guided lightning gun. The device uses a short (two trillionths of a second) high energy (50 billion watts) laser pulse to ionize the air along the beam, creating a conductive channel of plasma. The channel then conducts an electric charge from a high voltage source (a taser on steroids) towards a target. Additionally, this highly increases the range of the electric discharge. The image above shows a directed bolt of lightning earthing itself through a car. Which is all kinds of cool.
I wonder if you could use two lasers, fire one at a storm cloud, the other at your target, and smite your enemy with actual lightning
Anywhoo, source here.
