Roboticst/artist Natalie Jeremijenko spoke at Google's "Solve for X" conference on using technology to solve big world problems, in this case "drones for good". I'm not sure she came up with anything particularily new, but thought it was worth sharing here all the same.
From the video description:
Problem: What if war could be fought using technology that's more humane and could acheive political or tactical goals without killing civilians?
Solution: Targeted military force could do limited harm or potentially do good instead of the drone missle strikes that are used today.
Technology: Natalie proposes unmanned aerial vehicles (UAVs) could be used in new, creative ways.
