I truly believe that the talented people on this forum will find out the answers to the Figeura device.
Way back in the forum on post 87 BaJac stated "JUST REPLICATE THE DEVICE AS SHONE IN THE PATENTS!!!"
I agree.
When I read about the device on "Practical Guide to Free Energy Devices" I had a few thoughts about the device.
The first thought was, how can one get a true sign wave without varying the ohms to follow the wave. Oh course,
since then I read this happens when a square wave is run through a coil! Oh well.
I will start on four sets of transformers as soon as I finish building my coil winding device.
Good luck to all, including me.

Note that TEST #1 generated an output rms voltage for the secondary of about 16.5 Vac. To get the 120 Vac target, I would need to build 7 more sections if using that particular tap (600 turns.)

I want to say that a secondary coil with 300 turns is still not ideal. For the next section, I am planning to make a secondary coil with 500 turns of #14 AWG.

Shadow, when do you estimate your setup will be goo for testing? I love to see how Figuera's original device would have worked?

I just finished for the night but I wanted to share some more findings.


As illustrated in the figures that were posted, the PWM function can be used to generate the two primary voltages. However, the problem with the step driver is that it behaves as a current source. In this initial stage, we want to get away from the current source because it can create issues that can complicate our understanding of the Figuera's device. I am working on using the PWM outputs from arduino and connect them to a high power H-Bridge.


In addition, the performance of the device is better for the taps at 600 and 750 turns. The taps for 200 and 400 turns generate wave forms with a lot of harmonics. The 200 turn tap is the worst.


I will keep you posted. Thank you.

Probably finish in the next two weeks or so!
