Hi there
air gap well I think it is all how strong you magnetic field is, 5thou is not practical unless you have top bearings, and the unit well machined.
I also think that it is the way that you design the unit. most motors and alternators have a bigger air gap than that, 2 to 3mm or around 3/16ths.
If you take the axial flux approach, and also use the Tom Breadens thinking of repelling magnetism.
The Bedini ten pole energizer, if any of you can get some information it would be helpful to our group.
Such as the out put AC before it is rectified, the rectified DC and its voltage and current.
Why, well he shows a big set of batteries, they look like 19 plater’s, if he can supply a big enough charge to a 24 or 48v system, you may be able to use it for alternative power.
I can not find any out put stuff, he mentioned 1800amp hour batteries, I would say that was the total of the battery bank.
So they could supply 100amps for 18 hours, but at what voltage. Was the battery bank 12 24 48 ? or 2x6V 900 A/H
With out this information you could not spend $US5,000.
My system should be a lot better, thing of using both ends of the magnets.
If you do get a big enough supply, think about using this system on your house.
I hope the attach comes out may have to save it as a pic.
Here is the caption to go with it
The Bedini Energizer could be your alternative power supply, or your own
What is required is a new switch board, (take it to another home) remove all the house circuit from the bottom of the fuses or breakers connect then to the new board. Have a legal power outlet fitted alongside your old switch board, this is used to trickle or charge the battery bank. The battery bank now supplies your power via a DC to AC inverter to your new switch board.
The is know as a no break system, and a more complicated version is used by many large information companies that use big computer systems. So do the same, if you have a big enough alternative power supply.
