Computer scientists Brent Griffin and Carrick Detweiler of the Nebraska-Lincoln University have turned a quadcopter into a flying wireless energy delivery system. The aim of the research is to provide sensors in remote locations with electricity. But we know that once the system is up and running you will want one too.
As a carrier the scientists use a Hummingbird quadrotor helicopter made by Ascending Technologies. They added equipment weighing a total of 127 grams (4.5 oz). With this payload the flight time is between 15 to 20 minutes and the maximum speed 50km/h (31mph).
