Some pic's to give you an idea.

[daveparf]

this is the new drive cylinder.

A rough drawing of sorts would help people visualize what you have. So far I see too many possibilities to know for sure what you are doing.

[daveparf]

this is the best i can do

Hi daveparf, In the first pic this will be the optimum set-up but , will cause the most resistance.
In the second pic, is the flow of water spinning the magnets?
I like the idea of using water , since we have so much of it.
Not consuming it , just recycling it.

yes water spins the drum of magnets, i have videos on youtube "inline water generator".
what setup will give less resistance?

[gyula]

....
My question is,
Should all my coils be wound the same way and positioned so one side of the coil has a north pole magnet behind it and the other side of the coil have a south pole magnet behind it? i am using 4 coils so they will all be positioned the same way. I am thinking the north magnet will send current up one side of the coil and the south will send the current down the other side of the coil?

Thanks Dave

Hi David,

Interesting idea, especially if it can be permanently built into main pipelines feeding several homes, districts etc where there are quasi continuous water consumption day and night. Of course it can also be useful within a single home.
To answer your question I can only help by pointing to a thread here where Bedini was quoted how his so called Window motor works. The Window motor resembles the most to your mechanical setup and you can see how he positioned the coils and the magnets. Of course it is a motor setup and you have a generator setup I know but I think if the motor setup is understood then the generator setup can also be clearer.
Here is video on the Window motor:

Here is the thread:

I have not built coils with the shape you show in your picture or coils like shown in a Window motor this is why I answer like this. If you feed some hundred milliAmper DC current into one of your coils from a low voltage source and explore with a compass the static magnetic poles developing around such coil format you have, then it may also give useful info what poles are to be present and where, then you turn your mind into "generator mode".

Thanks Gyula, you got me thinking now
I think my idea will work then, i tryed it the normal way by aranging the coils clockwise then anti clockwise and so on last year on the first generator and got less volts and the drum would only spin slow, The joys of inventing!

Well i got 10.5V and 5.2A at about 800rpm from one coil with 100 windes of 20G wire, so it works
Thanks peeps

Coils and Magnets

I think it is important to understand electron direction when a magnet passes over a coil. The attached picture should demonstrate this.

As a result (assuming you want three phase), I think you should wind all your coils in the same direction but the size and spacing of the coils are critical so that the magnetic fields line up.

Then you would need to decide if you want a Star or Delta config.

my next question is what coil setup will be best for conecting to a grid tie?
volts?
AMPs?
single phase or 3 phase?
I want as little resistance as poss.

Grid Tie

I am not an expert, but I have done some research and have put in Solar Panels, Wind Generator, along with large battery bank and a High Amp Altenator on my sailboat. That gives me some experience.

With 3 phase AC, you can use an ordinary 3 wire outdoor extension cord from your generator to your bridge rectifier. AC will transmit over a long distance with 14 ga extension cord. DC will need welders cable to go the same distance. Your bridge rectifier should be close to your batteries and grid tie inverter while your generator could be outside somewhere.

You would have a multiple of three coils to go 3 phase. Either 3, or 6, or 9, or 12, etc. EX: If you have nine coils, 1,4,7 are tied together, 2,5,8 are tied together, and 3,6,9 are tied together.

As far as your picture of your coil and magnet setup, you have the spacing right where north is on one side of the coil and south in on the other side of the coil (assuming N,S,N,S,N,S setup on your magnets). You can add more magnets and shorten the width of the coils. Basically, maximize the number of magnets and coils which should maximize the current.

You want to convert to DC before using a grid tie inverter. The ones on the market, both sense and match the sine wave coming in from the power company. A commercial grid tie inverter is essential so there is no "Out of Phase" on your power. You want to match the sine wave coming in. The grid tie inverters are required to automatically shut off when there is a power failure, so you will not transmit AC while the power companies are working on the lines. You need to pick a grid tie that matches the voltage and watts for your system. There are a lot of grid tie inverters on the market.

If you go to batteries first, a good option on an inverter is a low voltage shutoff. This way, you will only add AC to the grid as long as the battery is up. Some grid tie inverters plug in directly to an AC house plug. Some inverters require a certified electrician to add it to the circuit breaker box.
