'Rick Friedrich's Replication of John Bedini's "Directory:Bedini SG"'

Replication accomplished Nov. 8, 2004 using CD drive for bearings and CDs to hold magnets. This was several years ago. Since then (it is Aug 2007) I have made over 100 models of Bedini technology. See the following pages for a few more:

I created some webpages here: and a full presentation here: and I am helping people build and test here:

I have made several machines but have been reworking them for the last few months. As of Feb 19 2005 I am just about finished testing my new modified CD drive setup. It is charging batteries faster than draining them. I am reporting this on the SG list and will add info here and on my website when it is all complete.

It does appear to me that using only two batteries with most machines will only give you an overall lower charge or amont of useable power. But with four batteries charging we have been told that the overall system charge will be greater with the basic SG.

While one receiving or charging battery alone, or with one battery in relation to three other charging batteries, will charge slower than the losses in the powering battery, nevertheless, with two or more charging batteries the charge is more than the loss of the primary battery. Mind you I think also that it is insignificant in regards to useful power. But it is real, especially in relation to the losses in the circuit and wheel.

I have been running my latest SG (see my website for pictures) continually (only occasionally stopping it to check resting voltages) using only three marine deep

cells. The way it is running now I think I could at least keep it going perpetually, but I do see slight gains in overal system charge. I started with one charged battery (that probably was not completely charged) 12.61v, one of which was discharged to just a little lower than 12v, the other was 12.37v. The two more fully charged batteries were being swaped back and forth on the SG while I did a 20 hour 1.61 amp load test on the third battery. There was thus no doubt a little loss during that time on batteries 1 and 2 (as was the case when I only used those two batteries on the other SG wheel). This wheel is much better (it has smoothed out and is very very fast) but I would still expect some loss with only two batteries. However, when I added the discharged third battery I noted a slight gain over two days.

Then I made an adjustment with my resistors I noticed some better results from that

point on. With that change and removing all my #14 wires and using only #10, and shortening the lengths of overall wire, I noticed a more rapid gain (though slow and insignificant). Here is what I just measured:

After rotating the two more charged batteries (while constantly charging the drained battery that was down to 12v), I just now disconnected them and measured them at rest at 1. 12.20v, 2. 12.67v, 3. 12.62v. I did this in the same way as I did at the start. When I reconnected them I got 1. 12.26v (#1 was formerly powering) 2. 12.51v (#2 now powering) and 3. 12.61v. This is definitely overall gain with only three batteries (two of which are identical and have been rotated for about a month total on another SG). The other battery was a discount battery out of date and only charged with a regular charger while powering the useless car batteries (now living again) in the previous experiment. I did let that battery (#1 battery above) go down to 8v or less too sometimes.

So battery 3 is now almost back to where it was before I did the load test. It was 12.67 resting and 12.47 when I started the 1.6 amp load on it. I should have fully charged all the batteries (not very scientific here) but if I can get them more fully charged than before (especially when one was drained), then we do have gain. Which I do see. The other batteries are about the same place as they were when I

started recharging the third battery. I will spend a little more time charging the third battery and will then see if the first two can also be brought up to a fuller charge.

The system draws 0.57 amps the way it is set up with better wiring (no knife switch now). Before that it was drawing 0.23 amps for two+ days. These batteries are rated for 205 or 215 hours/ 33.

So if I can get these results with the simple SG with only three batteries, then this is evidence of OVERALL perpetual Unity and I think OU. I definitely am not loosing. Certainly at least maintaining perpetual rotation. Now if I add two more identical batteries I am certain I will see faster overall gains.

Unfortunately after I wrote this I learned that I had shorted out my circuit for about 2 hours or less. A clip had touched another place and slightly drained my batteries. Yet I still am a head overall from where I started with these three batteries (including the 20h 1.61amp load test). I may have lost a day of charging by this accident. But I will report the details when it is done.

Directory:Bedini SG:Replications:Rick Friedrich:Dec. 5 2004 - general observations of interesting charging phenomenon.

Nov. 8, 2004

The 9 volt batteries did not work as well and the CDs eventually stopped moving. The CD magnetic wheel is not supported on the top CD and is only supported by a gutted CD drive on the bottom CD. Four magnets are positioned with the north facing out at the four corners between the CDs. Because the top is not supported it tends to wobble.

But with the 12 volt batteries hooked up it has been going for over three hours (as of 5 pm Monday Nov. 8) with a continuous wobble. It does not seem to be going faster or slower.

I will wait for instructions as to whether I can share the input battery with the other two proposed. I do not plan to change anything from what is called for and I am eager to work with John or others in taking the next steps. I am not going to attempt to test the current going into the charging battery (as advised) but I have checked the voltage of either battery from time to time.


Nov. 8, 2004

The power battery (deep cell) remains at the same voltage as when I started (12.14) but the other battery, which had little power left in it, has increased from somewhere around (I don't remember exactly) 12.04 volts to 12.34 volts in three hours.

Replication Specifics

The wood board on top with two screws, along with the large CD case cover on the side don't need to be there. They were put there as support so I could put a smaller CD case cover over top of the spinning CDs in order to give support.

But I did not want to add friction to the system so I left it off. The coil is not mounted at all. The wires are #20 and #22.

An attempt was made the previous night with a coil wound approx. 900 times. But I believe I either made the circuit wrong, fried one of the parts in soldering, or wound the coil wrong by allowing too much space between the parallel 22 and 20 wires. I wound another coil only 500 times and did the whole unit over again. It worked right away.

The plan is to find a non-metalic wheel and place 16 magnets around it and then add two more coil systems to share the wheel and magnets. In theory, this should make three times the charging capacity.
