Hi OUG,

Thanks for your tests and answers. I believe we all expected this kind of behavior. The real problems is that the water molecules aren't happy to be put to work, so they are fighting back with us. The more they travel from the center towards the end of the horizontal pipes the more they fight. Agree with all your conclusions.

I believe we have to back engineer the device. I'm thinking we need the Pelton turbines 1st. They will decide how big the entire test machinery will be, and dictate everything: water flow, length and shape of the horizontal pipes, cross sections and rotation speed, power of the motor and generators and so on. We cant go to some workshop and ask the guys there to execute a few. They are quite complicated and need a lot of calculation and careful design. For testing we need something simple and easy to modify if needed. I'm thinking on plastic tea spoons for beginning. I'll start digging in this direction to see how we can manufacture some cheap but efficient Pelton turbines for our tests. Also buying them is not an option because they have very big prices, even the ones made out from plastic.


I believe i have find some simulation software to see if we can better understand how Coriolis work and what can we do to minimize it (the way i see it now: even if we can design a curved horizontal pipe that will minimize the impact of Coriolis with the pipe, the problem is still there. The Coriolis will then increase the pressure inside the pipes because the new coming water molecules hit the ones before them and so on. I'm not really sure. It is possible that curved or not the results with both designs to be similar). Regarding software no promises cause i only read a little, didn't even install it. Will keep u posted.

@vineet_kiran: interesting suggestion regarding the sponge. Didn't see it that way. Also i think this idea should be tested cause I can really "see" what's happen with the water molecules in this case and how much the water flow and pressure are affected by the sponge ... hmmmm

 For now, to make it a bit more clear. I made a drawing of the T/S-(Shaped) Turbine concept, which is being equipped with two Pelton Turbines… (this one is supposed to be a self-runner)

I like your work. It may help the finished design if you drop the Pelton runner and the generator from the end of swing arm and instead have one centre mounted up above the swing line. The centrifugal drive forces remain and much of the inertia weight is removed.

The drive resembles a pyramid shape with a hole in the top apex, so allowing water flow produced by the swing arms action.

@ Mihai, Nice Document on the Design Process of a Pelton Wheel. THX

@ miloszlaw, I think I don't understand what you are trying to accomplish by replacing the rotating tubes with your rotating cylindrical structure. (as can be seen in your Drawing) This because with a rotating cylindrical structure only, there cannot be exerted as much Centrifugal Force on the water compared to when we use a rotating T-(Shaped) Pipe Structure. And furthermore the guide way structure next to each individual Pelton Turbine is also unnecessary in my opinion. This because they are Impulse Turbines. (Please look for the inner workings of Pelton Impulse Turbines on the internet)

For the Self Propelled version, see the Rotation direction indicated by the Arrows. (Counter Clockwise in this Case) This version only works with pulleys and driving belts. So No generators attached…

Hi all. I decided to give it a go to this project. Evolution will be slow 'cause lack of time. I'll keep u posted with the findings along the way.

To OUG: did u receive my pm?

Mihai

By replacing the rotating tubes with rotating cylindrical structure maby you can reduce the Coriolis effect without reduce Centrifugal Force?

 T provides 82% efficient Pelton. DaS 60%.

 Inertia also active in DaS. Turbine is of heavy construction.

 DaS :-) active below zero* C.

 T once spun may continue,
