Kirchhoff's current law, described by Gustav Kirchhoff in 1845, states charge input at a node is equal to the charge output. In other words, all the electrical energy going in must go out again. On a ...

WASHINGTON, April 14—A team of European scientists has deliberately triggered electrical activity in thunderclouds for the first time, according to a new paper in the latest issue of Optics Express, ...

The US Navy has shot down its first drone representing a subsonic cruise missile using an all-electric high-energy laser. At the US Army’s High Energy Laser Systems Test Facility at the White Sands ...

Northrop Grumman weapon has finally managed to make a weapons-grade electrical laser, but it’s a bit of a beast. The new laser relies purely on electrically-powered equipment rather than the COIL ...

The US Navy has deployed a new electric laser weapon with massive defensive upside. The weapon can take lethal and non-lethal measures to disable or destroy targets. The laser was tested on a drone ...

Advanced battery technology commonly found in electric cars is now getting leveraged to benefit the military's laser weapon development. As lithium-ion batteries get smaller, cheaper and longer ...

Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed the prototype of what is believed to be the world’s first* optical receiver for use in laser communication terminals ...

A major current law has been rewritten thanks to the three-port transistor laser. Data the transistor laser generated did not fit neatly within established circuit laws governing electrical currents, ...

A team of European scientists has deliberately triggered electrical activity in thunderclouds for the first time, according to a new paper in the latest issue of Optics Express, the Optical Society's ...

What just happened? In what could be viewed as a sign of the often frighteningly uncertain times we live in, the US navy has shot down a drone using an all-electric laser for the first time. The ...
