It goes without saying that we all want laser trucks, or at least laser systems for our cars. This is one step closer to reality with ATHENA (Advanced Test High Energy Asset) developed by Lockheed Martin.

And whereas comparable surface-to-air missiles cost thousands of dollars, the laser is just a 50 cents a shot.
