This is very interesting. The oil submersion of server heat generating components allows efficient heat transfer at 40C vs air which has to be much lower temperature to efficiently transfer heat. Keeping coolant down to 40C is much easier, requires much less energy, than say 24C for air.
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.
