Not much to see in those videos other than he has the fans running.
Its not possible to defeat lenz, thats why it is a law hehehe.
Motors can be built in a way where the lenz law does not apply, or where it has less effect or where the voltage produced by lenz is opposed thus cancelling its effect. I am working on the second one, but even though I have dramatically reduced it on one coil it applies on others. This method cannot be applied to a fan as extensive modifications would be needed, better to understand the fan first.
The fan when used to charge lead acid batteries is capable of overunity, but the following rules must be applied.
1) The charge rate of the charging lead acid battery has to be in the range of C20, ie it takes 20 hours running to charge it.
2) The discharge rate of the charged battery has to be in the range of C20, By doing this and the above you are operating the battery at its highest efficiency.
3) The mechanical output of the fan has to be taken into account.
The overunity occurs in how the battery is charged, its in the battery and not the fan. The fan itself is about 25 to 30% efficient and the recovery is about 60% or less when measured. But the battery responds to this in an unusual way and charges at above 90% efficiency. Many theories have been posted about why this is but there is only one thing we can be sure of. The charge in the battery is real.
If we add this charge efficiency to the mechanical output we have more out than in, but in my experience only when we add the mechanical output. There are others that have exceeded this, or claim to have done so, but I have not. Im sure if you build the John Bedini SSG exactly as he has described, you will be in a good position to outperform this fan.
Let us know how you go on with the new fan
