Energy source

Why not just use whatever is spinning the liquid to turn the turbine?

Maybe because the turbine is already spinning; and the centrifugal pump is attached to it. I think the questionner is searching for adjunctive ways to utilize the turbine's energy (sort of like taking off the excess heat).

Absolutely no idea of how he can utilize the "pressure" drop (wouldn't the energy change really be a velocity drop?), however.

Sorry to put a dampener on your idea: go to wikipedia and look up conservation of angular momentum:-

Basically: you need to put energy in to keep the wheel spinning.

Not the point, Randall.

Here's this guy. He's got a motor going. It's got its own energy source. Now he attaches this pump to the motor. Doesn't affect the motor at all, it just keeps going so long as it's fuelled.

I think what he is trying to do is figure out some way to recapture the energy lost when the velocity of the water spinning out the spokes of the pump drops as it rushes out the end, so that it is able to be utilized as an energy source.

No idea how he could accomplish that short of some sort of reversed turbine blade; but stranger things have happened. Let's see what he gets!

I'll allow the poster to correct me if I'm wrong, but, this looks like an absolutely classic over unity machine.

"once in motion stays in motion, pressure differance stays as long as the spinning stays."

Well, what I'm going by is his initial statement that "you take a wheel and spin it..."

So I figure that the next step after giving it spin is to feed it water and allow the process to take place. Now, unless he's going to stand there and keep the thing going with his finger in the spokes, there has to be another way to keep it spinning. I don't think he's trying to power his power source with its own "power" (that would be too obviously silly); just trying to figure out how to use the end product.

As the liquid moves out from the axle it is speeded up and therefore the wheel is slowed down. You are just removing the energy stored in the spinning wheel.

Simply an energy balance chart would tell the whole thing. Once pressure gap like that is made use of as an energy source as the poster expected , there'll always be a need for other energy source to maintain such a pressure gap, e,g. pumping in more water etc. Energy in vs energy out, the net energy output would still remain 0.

Basically what you describe is a crude centrugal pump.

Of course you can take energy from the flow,.... just a bit less than you put in.

Usually the case. The prime mover is being used for another purpose. The addition of water doesn't have to utilize any extra energy (eg gravity feed). Moving water out to the ends of the spokes might be a zero-balance effort, if it indeed takes more fuel/acceleration/power from the prime mover to do so. But since part of the purpose of this pump is to move the water out there, the question seems to be how that energy can be recaputured as it is dissipating. Washing dishes is a good example of a creative solution. The dog is shaking. Put a dish nearby. Perhaps a dish that develops a charge when it is wet, so you can wire up the dog to keep shaking.

Energy is required to accelerate every new drop of water from zero horizontal movement the required velocity.

It seems to be very similar to a super revving spin dryer in a washing machine.

The way to uses this energy may be to place dishes etc around the perimeter (combined spin dryer dishwasher).

My long haired dog achieves the same results when shaking himself dry.

Give up the whole idea.

1) It's a lot cheaper.

2) It will take less effort.

3) No one will ridicule you.

4) Let some one else do the design then ridicule them when it fails.

5) Sit back and let another idea slide by into the waste bin of time.

6) Know when enough is definitely enough.

7) And just for good measure make use of a better person knowledge as so many do on this forum.

And, if I may add a few more pieces of good advice ...

Never give up on your ideas.

1. We'll miss out on your findings/new thinking if you run away and hide just because you're not sure or well-informed about them.

2. Don't run away from the effort to examine your dreams.

3. Pay no attention to ridicule. If you want to fly like an eagle, don't let the turkeys keep you down.

4. If you're on the receiving side of new or uncertain ideas, be supportive. Nothing more downing than a ridiculer. Offer constructive or leading suggestions. Support the dreams of others. If you can't support them, shut up.

5. Human progress is enhanced by the dreams and ideas of those who aren't interested in sitting back. When you think you've failed, get back up again and start over with what you've learned from your failure.

6. Know when enough is definitely enough. Then branch out and try other tacks on the same wavelength (to mix a metaphor), using your first set of ideas as a base for exploration. But don't give up.

7. Bring your innovative ideas to this forum, where able people may see the visions you have and offer information, encouragement and help to develop or alter them.
