The Front Cover

Over the years we have published several articles about different devices for capturing high altitude wind, also called airborne wind energy (AWE). AWE articles we have previously published were about kites, tethered wings outfitted with turbines, powerplanes, and lighter-than-air tethered rotating devices. And now, in this issue on page 7, we have an article focused on the development of an innovative design that has been named PAULA for short, or Power Amplified Upper Level Aerogenerator.
