This is a video of a flamethrowing drone employed by power line maintenance workers in Xianyang, China, burning a 40-foot piece of nylon netting that had gotten wrapped around an ultra high voltage (UHV) power line and was affecting the line’s performance.
Workers flew the flame-throwing drone towards the net, spitting fire at about four to five meters away from the nylon net and burnt it to the ground. In ten minutes, the power line resumed its normal operation.
