Military Working On Laser Powered Drones 95

Posted by samzenpus from the amazing-laser dept.
disco_tracy writes "Modern militaries depend on fuel. Nearly 80 percent of the supplies delivered to operations in Iraq and Afghanistan consist of fuel, and it's no surprise that those military convoys are frequently the targets of insurgents. In the last decade, 1000 soldiers have died delivering gasoline to military operations. A new approach using lasers could provide power to drones in flight or to machines on the ground and remove the need for gas deliveries to army bases."

    "remove the need for gas deliveries to army bases", so where does the laser power sent to the drones come from ?

    Or are we going to aim big orbital lasers at the army bases? That sounds like a good idea.

    Also a dispersive light beam as described is not going to be efficient. R^2 losses on defocusing and all that. So more power needed at the base to send up to the drones.

      From coal fired generators. Afghanistan has plenty of coal. Another option is solar arrays. Afghanistan also has plenty of sunshine.

      Probably not, since you don't have the weight of the fuel on the plane. Besides, coal/sunshine is orders of magnitude cheaper than aviation fuel. Plus you get much longer loiter time.

I don't know how much power one of these reactors can produce but it seems that the military has no shortage of trucks to keep bringing in fuel. Instead of bringing in fuel they can keep stacking up nuclear power plants until they have enough to meet their power needs.

    And how many of those thousands were during combat operations? Less than 100. Distort things much? You're still going to need to get fuel to the laser so it can power the drone ... unless you think its just going to run on sunshine and rainbows?

    Most fuel accidents happen no where near combat zones due to people being slack. Tensions in combat zones and natural selection tend to keep things actually safer in that respect.

B) The location of the refueling system. Invisible laser you say? Doesn't exist.
