Deadly bushfires have swept across South Australia this week, destroying countless properties and natural spaces. One ingenious professor was able to save his rural home, however, by remotely activating sprinklers using a smartphone. Simon Maddocks, the President and Vice-Chancellor of Charles Darwin University, had been notified of the fires by friends and messages sent by the Country Fire Service (CFS). He was sitting comfortably in his Darwin office, far from danger, but knew his wheat farm on the other side of the country was at risk. Maddocks started tracking the flames from over 3,000 kilometers away using CFS maps on his phone before connecting to CCTV cameras at his house.
