> airplanes are not good for the environment. > to fix it requires capital and public demand. In my engineering career, one thing I've learned is that if you fix problems B, C, and D, often it becomes a lot easier to fix orthogonal problem A, because the other fixes have made new things possible. I see what you are doing as fixing a lot of problems with flying, so then more attention can go into making planes quieter and more energy efficient. Perhaps yours is one of the steps to making planes as peaceful in the environment as birds[0]. [0] https://breckyunits.com/ifNatureIsDoingIt.html https://breckyunits.com/ifNatureIsDoingIt.html
