As long as he continues to ignore multiple engineers with experience and the simple physics of energy lost due to spinning those blades...
I have to siphon off our fire fighting pond after good storms, with 2" PVC pipe...it empties into a small wash about a hundred feet downhill....even if the water was spinning blades at the bottom, there is no way the pressure inside that 2" PVC is going to let ANYTHING casually wash back up the pipe....
