the wheel itself can be one pound, one ton or 10 tons

it does not matter

its the added weight of the extended rod falling

but if you have a wheel that is one ton, you will have more momentum available to use

thats not exactly correct -- if you have a wheel that is 1 ton, you will need counterweights that are a lot larger than those used on a "CD" wheel. Which also means your magnets have to be quite larger.

Well I hope this thing works for I cannot see any reason for someone to go through all Archer has just to fail, I hope he is right. I was wondering what would happen if you did this design on both sides of the wheel rather than just 1 side, why leave the backside of the wheel to do nothing? I would think you could get more out of it using both sides?

While the weights/rods pass through the two "unused" quadrants - Gravity is keeping the rods shifted to the lower-right, which is exactly where they need to be during this portion of their travel. so there's nothing for the magnets "to do" there..

I think the final goal should be charging a 12-volt, deep cycle battery.  As such, the output of the generator should target a 14-volt output.  I am of the notion that a store bought device would be difficult to match with a wheel build.  Build the wheel ? then design and build a generator around it??

2 options ? axial flux, or standard.  I posted the link to the axial flux plans earlier, it also includes info on how to wire a generator in 3-phase style?.

Here on some pics on the other, standard type home-brew generator I?ve been putting together for one of my builds.

The device is low RPM?s, so I will be using pulleys (1:4 for now) to increase the RPM?s.

The coils are around 300? of #30 AWG on a 5/16? hex-tap bolt, with a tape layer in-between each wrap of wire, and with homemade plastic bobbins.

It is wired in 3-phase, star-pattern.  It will have a central wheel of magnets, with coils on both sides.  Target output is 14 volts and ?amps (we?ll see when it?s done!)
The AC output needs to be recitified to DC - using 6 schottky diodes will be the most effecient (see the pic of the breadboard)

The pulley pic is just some hacked plywood for testing (12? large pulley with 3? small)
Real build will require real parts ? vbelt pulleys and belt.

1 thing I?m not sure of? bearing in the pulleys (like an idler) and a fixed shaft?.
Or bearings at either end of the shaft (rotating shaft) like maybe flange-mounted or pillowblock bearings?

Suggestions on this are welcome!!!

Well I was thinking on the backside you could place the magnets in a different arrangment to help give a little extra push/pull in the area where they arent "doing anthing" in order to make it that much easier on the other side for them to make it through the gate . I'm just kicking around some ideas it may not matter in the scheme of the design but its something I was thinking about trying if some of the builds already underway have troubles making it through the gate with each revolution of the wheel if it grows weaker each time nearing the gate due to friction or other losses in the system.

Hi All
This is the point I have been trying to make, weight matters if you have to much weight you can't push and pull the rod up and if you don't have enough weight you can't break the magnetic field so for this to rotate the weight has to be perfect which is cool but once you put a load on it it stops why because now you have to increase your weight to move the load and the weight is to much to push pull the rod but you can't add weight as its going so again it will stop because gravity has to much to do and can't break the magnetic field.
This is how I see it and why I think it will not work, I could be wrong time will tell but thats my thoughts.
Take Care All
