Spy drones in demand by U.S. police departments, but approval pending

The CIA drone really does look like a real dragonfly – see the photo to the left. The problem was apparently with the flight control system, as the craft could not cope with crosswinds. This type of problem can be solved much more easily with modern electronics. The big issue with a craft so small is the power supply. Until we can get something as compact and efficient as the biological version (and there already ecobots that power themslves by digesting insects), the answer for robotic insects is likely to be beamed power.
