There are powered sailplanes, also known as motor gliders. https://en.wikipedia.org/wiki/Motor_glider > I know that you haven't made a point about the solar powered plane. It is > constructed like a glider, so what? Have you seen pictures of the Wright > brothers plane? You still don't get it do you, or are you being dense on purpose just to argue? There is some minimum amount of power required to keep an airplane flying. Powered sailplanes require very little power to keep flying and have wings with a very large surface area, therefore it is practical to have a solar powered sailplane. A common airplane such as a Cessna 172 does not have enough wing area to collect enough energy to fly, therefore it is not practical to have a solar powered Cessna 172. -- Jim Pennino
