This is very cool. The company Sonex Aircraft is working on making an electric plane. Granted this plane will not be used for passengers (just a pilot) and won't be hauling anything. Their stated goal is simply to make a plane that can be used to set electric flight records, but there are some very interesting technologies discussed in here. I think this is good. It's another outlet for engineers to biuld and test electric motors. Everytime someone does this the chances for a breakthrough that can move us closer to an electric car society happen. That is awesome.
I hope they succeed in their tests and that they are able to contribute something new to the overall electric car race that is going on.
