Sebastian Elbaum, left, Dirac Twidwell and Carrick Detweiler are on fire with their new patent for setting range fires with small drones. Elbaum and Detweiler hold flaming table tennis ball similar to the ones carried by the drone flying above them. The drone injects a liquid into the plastic spheres to start a delayed fiery process so the balls can fall to the ground before igniting. Elbaum and Detweiler are professors of computer science and engineering. Twidwell is an assistant professor and gangland ecologist in the school of natural resources. October 29, 2015.
