By riding across the carpet in my unicycle I build up a static charge. This charge is then transferred evenly to each ball. Since they all have the same charge their natural tendency is to separate thus keeping them up in the air. Next I will demonstrate the same effect by juggling chainsaws.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
