I worked for a guy who had previously worked for Boeing. He was a CFD expert and he said his job at Boing was to shave off 5% of the fuel economy of a plane by using CFD simulations of the wing to refine its design. It seems that 5% is a small number, but it's huge when your talking about one of the biggest consumers of fuel. My point, it's easy to think about leaving aerospace to do some fancy startup with a 10 year horizon to positive impact. We also need folks working within the existing companies, working diligently to reduce our consumption methodically in real ways that make real differences in the short term. If we can shave 5% a year in efficiency for the next 10, we end up in a very different place.
