German Laser Destroys Targets More Than 1Km Away 338
kkleiner writes "A German company has brought us one step closer to the kinds of shootouts only seen in Sci-Fi films. Düsseldorf-based Rheinmetall Defense recently tested a 50kW, high-energy laser at their proving ground facility in Switzerland. First, the system sliced through a 15mm- (~0.6 inches) thick steel girder from a kilometer away. Then, from a distance of two kilometers, it shot down a handful of drones as they nose-dived toward the surface at 50 meters per second."

Sheesh, and you people have the nerve to call yourselves nerds. A quick back of the envelope calculation:
Laser output: 50kW
Average microwave oven: 1kW
Duration of popping: 2 m. 30 sec. = 150 sec.
Therefore, 1 bag of popcorn every 3 seconds.
House volume: 2000 sq ft * 6 ft high = 12000 cu ft
Volume of a bag of popcorn = 0.25 cu ft
Therefore, 144k bags of popcorn would be needed.
(144k bags * 3 sec per bag) / 3600 secs per hour = 120 hours
Hope Val Kilmer isn't in a hurry.

The article seems to suggest that the laser was not simply going through air:
"[W]eather at the Ochsenboden Proving Ground in Switzerland where the demonstration was carried out included ice, rain, snow, and extremely bright sunlight – far from ideal."

Dinochrome. For the honor of the regiment.

Yes. Seconds are part of the official SI standard. That makes hours "metric". You basically blew any geek cred with that question.
