I am trying to insert the image of the self-runner block diagram above, not sure why it is not working. You will have to open the first link in the previous posting to see the block diagram.
Anyway, this device is not a self-runner. This is from 2007 so I doubt that there will be much interest.
The main problem is that the pick-up coil on the top of the wheel is not dumping any real energy into the charging battery. The coil is open-circuit for most of the time when the wheel is turning. In Rick's case, a commutator then shorts the "output" from the coil (through the FWBR) into the source battery. In John's case, a relay shorts the pick-up coil output into the source battery while disconnecting the source battery from the Bedini motor at the same time.
In either case, when the switch closes to connect the coil output to the source battery, there is no current flowing through the pick-up coil. Also there is no capacitor across the FWBR to collect any energy from the rotating wheel. Therefore by definition there is no energy available to pump into the source battery, because there is no energy stored in the pick-up coil, and there is no storage capacitor. The coil is only generating EMF. Rick and John may believe that "pure EMF" from the coil is charging the battery but that's not true. So when the switch closes in both cases, the "output" from the FWBR gets instantly clamped to the source battery voltage.
In both cases, whatever energy that might be pumped into the source battery would be coming from the magnet(s) that might be moving across the pick-up coil during the brief period when the switch is closed. Neither of them checked that, so we don't know. When John K checks the timing for his relay-based switch he shows it to you relative to the magnets that are moving past the main drive coil, and not past the pick-up coil, which is what he should have been looking at.
So this "self running" setup for Rick's version, and for John K's replication, is simply a standard Bedini motor setup with an extra pick-up coil where the pick-up coil is possibly pumping an insignificant amount of energy into the source battery. Whether or not the pick-up coil is pumping any energy into source battery depends on the timing of the switch closing and where the rotor magnets are relative to the pick-up coil, and neither of them checked this.
It's interesting to note that Rick actually tried putting a capacitor across the DC output of the FWBR because that's normal practice. He doesn't mention the value of the capacitor, which he should have. Rick says something like, "the 'effect' goes away when he adds the capacitor and the motor starts to really slow down."
The motor slows down when Rick adds the capacitor across the output of the FWBR because for the first time, he is really putting a mechanical load on the rotor! The pick-up coil is charging the capacitor in this case for a dump of that energy into the source battery, and that causes a mechanical drag on the rotor. In other words, when he finally sets up the "self-charging" system properly and it is really supposed to "self charge," the motor croaks. Instead of trying a smaller capacitor, Rick gets rid of the capacitor and now the rotor turns at a normal speed. By removing the capacitor, he removes any possibility to recharge the source battery through the pick-up coil as he originally intended to.
There are so many other holes in these presentations that I won't go there in detail. Both Rick and John look at the battery voltages. The last third of John's clip focuses on the multimeter displaying the voltage for the source battery. If he sees a 1/100th of a volt increase in the displayed voltage this is interpreted as "evidence" that the battery is recharging. Neither of them try to make any measurements of of what's going on in terms of power and energy.
The claim that these two motors are self-runners is false. They both had large enough battery sets such that with swapping and the whole nine yards, both batteries would run out of juice within a few days or perhaps within a week or more. The "source battery recharging" circuit in both setups is simply not working.
This kind of stuff is in a way just too much. I think that some soul-searching needs to be done here, by everybody. What people need is some basic knowledge and then to try to keep working on the learning process as time goes on.
