You can use this to charge a cap, disconnect the input circuit then discharge cap back to input. THIS IS NOT WHAT THE BATTERY LIKES...but this is how it can be done mechanically. There are other uses for this. Perhaps 1/2 the circle can be to power the SG from the cap, disconnect, power from battery, disconnect, repeat.

I used this switch to discharge a cap back to the front battery. The voltage goes up and continues to do so for even up to 1-2 days...appearing to be a self runner until it damages the input battery...either charge them or power from them but not both.

The above is description and comment I posted on youtube. I just uploaded that video..that was from a while back.

Hi Aaron.

This is the next step of experiments for me. I want to find out if I can charge the primary or backpop to a cap that runs the sg. I have heard you say that backpopping the primary appears to work but it eventually gets fluffy and damages the battery. May I inquire as to the size of capacitor used to back pop? Or was it from a coil like Ricks?

I have built a 16 pole alternating nsns bicycle rim and I am currently working on the shaft so a timing device can be coupled. I want to try a back popper with a large uF, to experiment and see if a single flatish battery can be charged up to reasonable levels (13.5) AND then drained before the cycle repeats.

I also have a small window motor that I want to convert to the half cole circuit and develop a ss switch to periodically parallel the voltage off the bridge into the run cap. I will be posting some pics soon, meanwhile I would like anyone elses input on this particular variation.

front popping

Hi Ren,

With gel cells, sending power back to the front while running, even if input while the circuit is disconnected seems to damage the battery over time and sometimes the damage is not reversible. If the gel gets too dried out, it can't be rejuvenated. If regular liquid lead acids, I think they hold up to it better but still, once in powering mode, it is almost pointless to charge it at the same time...in my opinion and from my experience.

I used small few hundred uf caps up to multiple 33,000uf caps.

I have tried a 2000 turn trifilar coil, which I wired in series like Tesla's pancake coils to boost the voltage but I didn't use the N/S magnet configuration, which in my opinion pushes and pulls the field to increase the voltage AND the coil acts like a capacitor I believe...same thing as the caps as far as what I observed happening to the battery on the front end. I could get voltage in the hundreds range but not the thousands range.

There are other ways to recycle the output back to the front without charging the front battery...I have tried many variations but few are worth doing.

In some of the information I've looked at, they basically pointed out that the charger is pulling the ions one way across the plates.

It would make sense to think that there is a certain momentum involved in either charger or discharging, so that in a large battery this process works against itself if done in too short a time from one another.

Your kind of getting into a Gray area here. You want to keep the pulse high and short but its ruining your battery. I would try to either clip the magnitude of the pulse or increase your mean frontal area of the battery by placing 1 or 2 more batteries in parallel.

There has to be a way to charge the run battery no? We do it everyday in our cars. Perhaps the design of a car battery would be more suitable for backpopping?

Some progress made on my next project. Trifilar awg 18 @ approx 150ft each strand.

Been taking my time trying to get the rotor as balanced as possible. Working on timing belt and pulley next.

Jim Watson's Machine

Hi,

I like this idea, which also can be used on Lindemann attraction motor, but maybe battery conditioning is required before attempting to back pop them? The question I always had in my mind is that if back popping destroys the batteries, then how did Gray, or Watson or even the 10 year old schoolgirl manage to do that without damaging the batteries? Rick hasn't mentioned anything about this, as much as I recall.

car battery

I believe the alternator is powering just about everything when the car is running and the battery is really just mainly starting the car and some of the alternator output just keeps the batt topped off so the battery isn't really powering a load except in the beginning.
