Every energy source is energy harvesting at some level (even oil, gas, hydro, coal, geothermal, wind, and solar). It seems to me that the emerging Energy Harvesting Market should exclude those sources in the market analysis and only include the harvesting of "incidental" energy (vibration, local temperature gradients, ambient radio waves). Otherwise the statistics will be "double dipping" energy sources.
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.
