 I keep thinking of the stress that 3 rps puts on a structure and then I thought of your device at 12 foot wide. From a structure point of view, you are going to need top mounts for you generators or they will rip out of your machine.  When it come to CF the further away from the center the greater CF effect. So the larger it can be made, the slower it will be allowed to spin.

Hi Telecom,
 
Sorry for the Delay in my Reaction. But to Create a Table Top - Model (depending on the size of your table :) ) I would suggest the following parameters:
 
(I shouldn't go lower than a 0.5 m Radius and 10 Litre/Second Flow Rate, because then the output power becomes below usable figures)
 
Parameters:
Rotation Radius 0.5 meter (Feed Pipe/Penstock radius)
Rotation speed 6 rps (Rounds per Second)
Turbine Flow Rate 10 Litre/Second (0.01 m^3/s)
 
Centrifugal Acceleration: (@ 6 rps and @ 5m)
710.612 (m/s^2) / 2 = 355.306 (m/s^2)
 
Hydro-Power Calculation for Each Turbine:
1510.05 Watts =  0.85 x 1000 x 0.01 x 355.306 x 0.5
 
Total Power:
1510.05 x 2 = 3020.10 Watts

Hi,
what should be the dia of the pipe?
Also, how do I take out power from the turbines/generators - they are rotating
at 360 RPM???
How do I connect the wires???
Regards

@ AB Hammer,
 
From a structure point of view I think that there must be some optimum. If you build it too big and spin it too fast, no structure will hold. And you are right about the turbines/generators. You want to place them at the circumference of the rotating Feed Pipes/Penstocks where the Centrifugal Force is on its maximum. Because of that position, the stress exerted on the Turbine/Generator will also be on its maximum, so the Turbine Mount also needs to be fairly solid.
 
(It can be challenging to build, but I don't think it’s impossible...)

@ Telecom,
 
For a Flow Rate of 10 Litre/Second I can imagine that the pipe diameter must be somewhere around 20 centimeters. And to take power from your (rotating) generators, a slip ring arrangement can be added to the system.
 
(I know they are not presented on the original T-(Shaped) Turbine Images, but these are more like a presentation of the conceptual idea)

Nice work so far. I like seeing good construction. Water pumps need priming and I wonder how you are going to prime your system.

If I understand the figure correctly,  you are expecting the centrifugal force to lift the water  from center pipe, which is vertical part of 'T'.   But practically when you rotate the entire thing,  water at horizontal portion comes out due to CF ( if water is present initially),  after that air enters from the turbine side and fills the 'T' portion.   Water will not be lifted up from the 'T'.   

You will get continuous water flow in the 'T'  only if centrifugal force developed is more than the force created by external atmospheric pressure.  To achieve this you may have to rotate the entire thing with terrific, abnormal speed because the external atmospheric pressure which is 1 kg/cm.sq  is quiet  a huge pressure.

Instead you can fill  the 'T'  with  hundreds of thin  flexible capillary tubes   so that water will be lifted up in the 'T' due to capillary force.   So  that  the centrifugal  force  has to only  push the water towards turbine  for power generation.   Only then you can get continuous flow of water for power generation.

As per the following wiki page,  a  0.4mm capillary tube can lift the water upto 70mm.   So,   if you use a bundle of 0.4mm capillary tubes,  your suction lift  should be less than70mm.

This looks very impressive!
Looking forward for the video!

@ Newton II,
 
Because of the Centrifugal Force working the water out, a vacuum will be created at the T-(Shaped) Turbine its water inlet. This vacuum will suck water in, so that it keeps running... (Believe me I have tried, it works!  :) ) But thanks of course for the capillary tubes suggestion. There can be done nice things with them...
 
Please wait and see how the system gets primed, when I have uploaded my video.

 Good videos but I would suggest a battery powered drill to make it a bit more dramatic.  ;)

It performs beyond my wildest dreams!
You can attach a bicycle type sprocket with a crank to help it rotating faster,
but otherwise it works great!

 When you understand water pumps you will find that most of them are Centrifugal. That is the reason they need primed and the reason I had no doubt that it would pump. The concept of putting generators in the system is what is cool. But will it be enough to be a viable energy supplier? This is what is hoped for.   Here is a link of a search that may give a few more ideas.  I typed in (Centrifugal Water pumps design)

You can start it like this one: https://www.youtube.com/watch?v=ZiMtFWkFgEw. Notice the spinning effect produced by the nozzles.

To continue on the comment of AB Hammer, yes the system has the same operating principle as a Centrifugal Pump System. Except for the fact that a Centrifugal Pump its impeller is normally fully submerged under water. (which creates a lot of resistance) In case of the T-(Shaped) Turbine Concept, about 98% of the System is running above the water, what's also a good thing in my opinion...
