Using a Clock Pendulum to Generate Electricity

Bill Mehess has invented a system in which a clock pendulum mechanism swings magnets into coils, allegedly generating enough electricity to recharge the clock spring as well as power other devices.

Earlier version of Bill Mehess' pendulum clock generator.  Chain drive mechanism at the top is for rewinding the spring on the clock.  On the middle, left of the device are two magnets protruding into two coils, which charge the capacitors, which charge the batter, in this iteration, which runs the windshield wiper motor that turns the chain drive..

PORTLAND, OREGON, USA -- Bill Mehess has devised a closed-loop system that apparently keeps itself operating, while having energy left over for external use, implying some new energy source yet to be appreciated by modern physics.

Without knowing of the work of Veljko Milkovic, Bill came up with a mechanical-electrical system that may employ a variation of the secondary oscillation effect described by Milkovic.

As the core element, Bill takes a 30-day clock pendulum he got from Korea that has a winding mechanism that keeps the pendulum swinging for thirty days. 

Bill attaches two magnets in place of the weight on the pendulum, and then places a fixed coil such that with each period of the magnet’s swing, they pass into the coil, inducing electrical flow in the coils.

On the receiving end of that electrical flow is a bank of 425 small capacitors.

Bill created a mechanical switch triggered by the movement of the minute hand of his clock, causing the flow of electricity to switch from one capacitor to the next after a set amount of time, in turn, until all 425 capacitors have each received a small charge of about 0.5 volts (varies between 480 and 550 mV, with an average of 5.25 mV). He said this takes between seven and eight hours.

At that point, he mechanically engages a switch that dumps the charge from all 425 capacitors into a second bank of 213 capacitors. In a future iteration, he says he would like to have a relay switch that makes this change automatically.

He then repeats the sequence, charging each of the 425 capacitors all over again, in turn. He said the second bank of 213 capacitors in parallel has a total capacity of 1 Farad, and rises about 2.8 volts with each cycle.

After repeating that about five or six times, over the course of a few days, there is enough charge (18 volts) in the 213 capacitors to run a 12-volt windshield wiper motor (draws 2-4 amps), which has enough torque to top off the winding mechanism of the clock spring via a chain drive. This alone represents a 100% mechanical-electrical efficiency. 

Further defying present physics models, in addition to topping off the spring, the system is also able to run other appliances. The system is generating more energy than it takes to keep it running.

The system only needs to run 62 hours to store enough juice to rewind the clock mechanism, but that rewind is able to power the system for 122 hours.

Bill said that the longest he has run this system continuously, without stopping, was 21 days; and he began with the capacitors completely discharged. He runs an LED light continuously during operation, and also occasionally runs a small motor to use up the additional energy available.

Set-up Specifics

He has chosen to use many smaller capacitors rather than one large capacitor inasmuch as the leakage rate tends to be higher on the larger capacitors. Previously, he was using a 12-volt battery. Mehess measured the leak rate of the 213 parallel capacitors (1 Farad) to be between 213 and 850 millivolts per 56 hours. In comparison a ten-inch-high 1.2 Farad capacitor, charged to 20 Volts, leaks to three volts after just half an hour.

The capacitors he is using are about ½-inch diameter by two inches in length. They are 4700 micro Farad, able to hold up to 25 volts, though he doesn’t take them much above 20 volts, where he finds that the linear increase in charge begins to taper off.

Due to the drag imposed on the swing of the pendulum by the magnets passing through the coils on each swing back and forth, Bill said that around 75 minutes pass for the “one hour” passing on his clock mechanism. 

The clock takes 15 turns to fully rewind from a completely run-down state. Given that it is a 30-day mechanism, that rate equates to about one turn per 48 hours.

Bill said that 65 hours of running the set-up generates enough electricity to rewind the clock about four turns, which is enough to run the clock for eight days. This bespeaks clear over unity, pointing to some new principle of physics not presently codified in academia’s literature.

While I might not have every detail correct in recounting what he told me, from what I can tell, the information he has disclosed in various places, including to me, is enough to build the thing.  That was my recollection from my phone conversation with Bill.  The concept probably has several areas of cushion.  You probably don't have to get it exactly right for it to work.

A discussion list has been created to facilitate the replication of this design and then to improve and optimize it.

Brief History

Bill’s accomplishment – at least an earlier version – was first published by Tim Ventura at American Antigravity on April 6, 2006. (Ref.) The next day Bill commenced a thread at the forum, on which he was active until recently. (Ref.)

He first contacted me on Nov. 14, 2006, the day he filed his provisional patent and posted his website. (Ref.) I recommended some tests for him to run to rule out the possibility that he might be seeing some battery artifacts. That, apparently, was when he switched to capacitors.

He contacted me again on December 30 to see about having the New Energy Congress validate this set-up. He had run the system long enough on initially discharged capacitors to prove that he indeed had enough energy to run the system, while also providing extra electricity for use. He wanted to have the New Energy Congress witness the device in operation long enough to confirm his claim.

Though the system was operational at that time, through manual switching, he wanted more time to automate the capacitor charge transfer switch, expecting to have it ready by the middle of January for a public demonstration in Portland, Oregon. 

I have not been able to reach him since that time. I’ve left several phone and email messages, which he has not returned. He also stopped posting to the Overunity forum.

One might speculate about a myriad of reasons as to why he went incommunicado after having been so responsive prior to that time. Is he alive? Was he threatened? Did he change his mind about sharing the technology?

The latter possibility is not likely, inasmuch as his original posting of the information is still on the net. He told me as well as the Overunity forum that he intended to openly publish the technology, though it would not be a true open source project inasmuch as he filed a provisional patent.

Finances can be ruled out as an issue, inasmuch as he said he was “financially comfortable.”

For what it’s worth, I should note a serendipitous event. While composing this story and first referring back to the Overunity forum, my computer set off a cuckoo chime. What is odd about this is that I did not set the computer to do that, nor has it ever done this before. I don't know how it was activated to do that. I do have small children who may have inadvertently activated that feature when I was not looking. Or it could have been picked up from the Overunity forum as some kind of benign virus. Whatever the source, while such tampering is usually not welcome, the synchronicity in this case was appreciated.

The next hour, when the cuckoo chimed again, I was cleaning out my spam messages, and it just happened that the first message on the page I opened had the subject line: "Turn back the clock!"

Shortly below that was another message in a thread that touches on a new movie that has been released about "The Global Warming Swindle." In the previous hour, I commenced a page to report on that movie, so there on my spam filter, at the moment the cuckoo chime sounded, were two subject lines that coincidentally had to do with the two topics I was preparing for PESN coverage.

Perhaps this was Bill’s way of getting through to me to encourage me to publish this account, which I’ve been sitting on since the turn of the year. Whatever the case, considering the work being done by Milkovic et al, Bill’s claim certainly is interesting.

Reminiscent of Bessler

Both Milkovich and this guy bring to mind a documented over unity "turning wheel" machine by a German [Johann Bessler] of several hundred years ago that always intrigued me.

He also used a pendulum on his machines, actually a T-shaped pendulum, presumably to help get over some dead point in the distribution of weights inside his machine.

The pendulum can be seen in these illustrations: 

They are of two different machines, both of them said to have been confirmed as working by independent observers.

Unfortunately the technology got lost, like so many others, and no one has been able to figure out the secret of Orffyreus in modern times, although there were plenty of tries.

Here is an overview of the story, in case you haven't heard of it...

The clock is a silly thing Stefan added to the website.  It can be turned off. I think it was in the upper right corner somewhere.  But it is not your machine.

On Bill Mehess.  I was very interested and shocked as he just went away.  Would love to know if it worked.  I am an electronics engineer and I know once I had the mechanical parts working (from Bill) I could add some of my magic to it.  With micro-controllers drawing so little power now.
