Brilliant concept, but will it work?

[ramset]

a better path forward would be

how can we make it work ....despite water pressure issues ??

http://news.mit.edu/2013/hydrophobic-and-hydrophilic-explained-0716
and  there are OTHER  attributes of water not really shared by gravity .

here some test Data

https://arxiv.org/ftp/arxiv/papers/1304/1304.1485.pdf

Foil shapes ....which involve boundary layers .. laminar flows  Etc etc
maybe the tubes have a useful [less drag]foil in the Middle..on the downside.

and then there is "ION charge" which can be stored in the fluid and put to work ?
attraction /repulsion ....

a very deep rabbit hole where many things need a good looking at...
IMO

and a Big PS on foils
Brad reminded ...
the foils which drove the google test unit strait into the wind at 2 times windspeed

against the wind

prior to that....you were nutty to even consider such ??
things like FRICTION were given as reasons for much expected failure......

now its old news and well understood 

lets be nutty....as Hoppy says
its what we do in the asylum...

until there is a discovery!!!

It will not work due to water pressure

Yes, you're right. That's what we figured out. Not that I didn't knew in advance that this device could not work, but now we've figured out the technical reason. That horizontal pressure gradient was not obvious at first untill we analyzed the shape on the pipes inside and between the wheels.
And it doesn't help making a notch in the wheel to make pipes with equal surface on front and rear, because that notch would have an area facing forward, and will be that extra surface that prevents the decive from running.

[Low-Q]

I was thinking: How is it possible to make those front and rear surfaces equal? What about deviding these pipes into portions of solid material, like hockey pucks, with some space between them and angle parallell to the wheels, so the total surface for each puck is equal on front and rear. If each wheel are 15° angled, and angle each portion so the front and rear surface is the same?
But then we struggle with the sideways pressure to force those pucks in and out of the water...
