Luxemburg lab drives PV efficiency News & Analysis 7/24/2009 Post a comment Scientists from the Luxemburg University Photovoltaics Laboratory have produced thin film solar cells in two different technologies both with very high efficiencies.
Drones are, in essence, flying autonomous vehicles. Pros & 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? Is the technology advancing faster than we can answer the questions it poses?
