Ion Thrust is a propulsion system that accelerates ions using electricity and, so far, has been out of reach for drone manufacturers for a variety of reasons. Now, Undefined Technologies Corp., a South Florida-based tech startup, is determined to focus entirely on designing and manufacturing a commercial UAV that would use Ion propulsion as the primary source of lift.

The professional drone racing circuit aside, speed bodes well when you are searching for survivors on a disaster site, or delivering cargo, or even inspecting critical infrastructure. But how do you get something done in the shortest possible time with limited battery life when you have to navigate through obstacles, changing speeds, and altitude? You use an algorithm. Researchers at the University of Zurich (UZH) have developed an algorithm that can find the quickest trajectory to guide an autonomous drone through a series of waypoints on a circuit. The AI drone beat the fastest lap of two world-class human pilots on an experimental race track.

This footage shows the extent of the devastation in China after deadly floods batter Henan, which is home to some 99 million people. At least 100,000 people have been evacuated in Zhengzhou alone – an industrial and transport hub. Also in Zhengzhou, 12 people died on Tuesday after being trapped for hours on a flooded subway line. But why is this more significant than other weather events? Facilities in Zhengzhou produce more than half the world’s iPhones.
