Can a Circular Flow of Water with Turbines Generate Sustainable Energy?

[Designer_Wolf]

I'm doing a little project of mine and am currently trying to figure out if my machine(being built) would work how i want it to work.
So i have a tube that goes in a full circle, this tube has 2 hand cranked turbines that give the water its initial motion to go round and round. Theres little turbines in the spaces between that would only spin through the motion of the water(being spun round and round by the hand cranked turbines)... So after all that confusion, would the turbines cancel each other out or keep spinning in one direction?

Do both hand cranked turbines pump the water in the same direction (eg both clockwise around the tube)? If so then the water will keep rotating as long as you keep turning the crank.

The little turbines in the spaces between will turn as long as the water is moving through them. How fast they turn will depend on their design and the load connected to them.

What's the purpose of this machine?

I suspect you may be suggesting that, once the motion has started, it would go on for ever.
Firstly, this is "Perpetual Motion" and we do not permit discussion about this topic on PF. Secondly, the nature of water flow round turbines involves a lot of turbulence. This would lose energy a lot faster than just emptying the water out, turn the handle and then watch it all slow down.

If you are only interested in the 'sense' of motion of the turbines and the resulting water flow (and turbulence) then are you asking the difference between your machine and two propellors in tandem in a straight tube?

But the context is interesting(?)

Then these 2 are propellers, not turbines.

If you keep cranking, they will keep spinning. The direction will depend on how you set the blades.

I'm aware of perpetual motion, i also know that there's no such thing as free energy. Something can't come from nothing, i was more interested to see if the waterflow would remain in the same direction. Thanks for the answer tho, gives me a little more insight into my problem :)

Its just another form of generating energy. Ofcourse its highly unlikely that i could develop a machine that charges a battery efficiently and fast, but i always found renewable energy amazing. Plus i just got a 3D printer to start printing some of my ideas. My whole idea of this "thing" is just hard to explain. But thanks for your help, atleast i know have an extra insight on waterflow :)

OK fine, I just wondered.

But what's the point in using a turbine system in that way when you could get higher efficiency by turning the alternator directly?

It would be more efficient to just connect the hand crank direct to the generator.
