Solar irradiation is the most optimum for energy harvesting that airliners can use but a system has to be capable of using multiple sources including vibration energy harvesting and temperature differentials the article is referring to. There are solutions available today but much improvements are needed.
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.
