Steve, as far as I can tell Sir. You are One: placing restriction in the air flow with the 'filter'. Two: The way the vanes are placed, is cause for air flow direction change which causes turbulence. Turbulence 'eats' energy which will show as energy lost (velocity drop). Perhaps try placing...
Sir. If you were to feed a vortex of air flow to the surface of the blades in the direction of intended rotation (depending on angle of attack) yes, you would impart force against it causing rotation depending on system resistance of course. I'm not sure as to why you would want to go to the...
I've always had an interest in the sciences and Nature though I've never been able to 'speak' math. I have a condition similar to Asperger Syndrome wherein I visualize or am able to 'see'. I love aerodynamics, cosmology, physics and just science in general. I enjoy thinking 'outside' the box and...
The technology of electrically controlled auto darkening welding lenses wherein the lens protects the welders eyes by transforming from clear to opaque within milliseconds is fascinating. I would ask, is anyone aware of a lens that is electrically controlled but produces a mirrored surface...
