I wonder if we should follow along with Luc but use these pancake coils as the transmitter/receiver pairs...?
We for sure need parametric oscillation, that's a given. To get it, we need a summator. What is a summator?
It's an electrical circuit that takes as input two disparate power sources and combines them into a single output that is the sum total of the two inputs. Think of a big 12 volt lead acid battery combined with a little 1.5 volt penlight battery--you can't just wire them together.
The concept seems simple enough, but is actually more complex than I had initially thought. You cannot gang together two power sources because the stronger one will always try to reverse power the weaker one. I learned this when charging two capacitors in series with back EMF. Doesn't work the way we want at all.
So I'm proposing a possible solution here. We time slice and multiplex the two power sources.
Suppose we charge two capacitors with the two inputs up to a particular voltage level. One will charge faster than the other. When one of them is charged and the other is not, we fire the charged one into a coil/transformer like any common DC-2-DC converter based on some clock signal. So in this instance, the stronger input power predominately passes through the summator. So how do we get the weaker input power to contribute?
At some point the weaker power input will finally charge its capacitor up to the preset voltage level we have defined. When this finally happens, then and only then do we gang the two capacitors together and fire them both, giving us a power burst for that particular cycle.
The beauty of this concept is that the weaker and stronger sources can switch places. Initially the main power source would be considerably stronger than the feedback power source, but at some point the feedback would actually overtake the main power source--this is where OU operation would begin to take over.
Now that I know we can collect the back EMF while at the same time producing a magnetic field that will induce a current in a collector coil, I'm beginning to see how this could all work together. If we use the back EMF to drive the CARC coil, then take the power from the collector coil and feed the summator, that's one possible solution and probably the most likely to work. We will still need some sort of current limiting to put a cap on this feedback loop, otherwise it could take off and self destruct, which it should do left unchecked if we have everything right.
Anyway, I have something here to work on for a while that I'm pretty certain we are going to need in order to make this project a success. Nelson didn't explicitly tell us about it, let alone how to do it, so I'll work on a solution and put it through some paces to see if my idea will actually work as I envision it.
i can charge 2 series capacitors with b emf
so matt. maybe you got a bad connection?
I'm doing my back EMF tests with the side-by-side coils, power on each coil, switch in between, so that each half of the coil acts like a capacitor plate. Switch completes the circuit, high voltage lamp across the switch to collect the back EMF when the switch opens.
You can see the very faint glow of the lamp when the switch is not operating. When the switch is operating, the lamp lights brilliantly.
