Bedini SG notes

If there's no rotor... It's not a motor. If there's no rotor... where else could the spike energy be coming from?  The rotor is actually a _drag_ and reduces the power available for the spikes. In the traditional Bedini motor the rotor is necessary because of the triggering system using the two co-wound coils and the moving magnets on the rotor. But the rotor wastes energy, it is actually a Red Herring, a shiny spinny thing useful mostly to distract the terrestrial primates away from watching their wallets carefully. If you want to recycle spike energy for some reason, like charging batteries, get rid of the wasteful rotor!

Quite right Tinsel, but Bedini also uses the ability of the wheel to output mechanical work as a part of the advantage possible. But
then he maintains it's not a motor, a contradiction.

Anyway I agree if it's the "spike" energy we want then there is no need for the wheel and it can only be a loss. Then we have a
basic boost circuit. 

And as well the high turn smallish gauge wire in the Bedini coils would mean that they cannot be very efficient by design, to be truly
efficient we need as least resistance as possible. Paralleling coils may reduce overall resistance but the individual resistance of
each wire remains the same.

I think the best setup would have thick wired very low resistance coils and use synchronous rectification or Shottky's and work at the correct
frequency and duty for the coils and input voltage ect. It would have low loss core material as well, maybe air. The switches would be
correctly rated mosfets or other more efficient switch and the switching would be done with as low a losses as possible.

I still think the patent is worded very strangely, it reads funny.

Any coils switched in a way so that there is an output from the diode will produce the same basic effect.
Weather it be driven by a trigger coil or by an oscillator.

In the video below I switch the opposing coils on a toroid both ways so that they act as an inverter the (secondary is an output as well),
And I also switch them as a boost converter by causing the current through the opposing coils to be the same way or just one set
it's a boost converter, if the coils are fed with current of opposing direction then it's an inverter.  Below the setup is discharging
into a battery. and the on duty is adjusted so there is no ring down time with both coil sets firing.

This video is old, I know a lot more now than I did then. Scope is across the secondary I think. Long time ago.

A switched coil is a switched coil.

Farmhand:

MileHigh, if a patent like Bedini's is lodged and as it is claimed, he says it is based on Tesla's radiant energy arrangements then
shouldn't Bedini's patent cite Tesla's Patent as "Prior Art" ?

Perhaps, but I am not the right person to answer that question.  It also suggests a conflict in citing something that is not actually in your own patent.  I think you caught him again.

I read the captures of the Bedini patent you posted and the prose is almost laughable.  It boils down to this:  One well-made 30-minute clip could explain the timing of the energizing and discharging of the main coil, and relate the magnetic field produced with the fly-by of the rotor magnet.  The good old L/R time constant and ... yikes!... Do the math for how a coil discharges into a battery, which in this case looks like a non-linear resistor.  My feeling is that exercise if well done would have the potential to "blow all of the Bedini threads out of the water."  But the potential would likely not be realized.

I know that I am repeating myself, but the heart of the analysis of the motor is to examine the timing of the circuit.  It all boils down to looking at and explaining the timing diagram for a given motor, and then extrapolating the timing analysis to a generic motor.  What happens when you make the coil inductance larger or smaller?  The answer is in the timing diagram.  Ask almost any question about this very simple pulse circuit and the answer lies in the timing diagram.  I am willing to bet you on the Bedini forums the analysis of the motor's timing diagram is almost never discussed.

Once you understand the timing diagram issues then go back and read those two excerpts from the Bedini patent and you won't know whether to laugh or cry.  There was that great phrase that I found recently that applies here, "Not even wrong."

MHOP rules!

I also feel there are lots of unanswered questions about the whole scene.  I don't actively read up on the Bedini scene but I know the whole narrative from a few years ago.

Okay, you start with a "dead" battery and you pulse charge it with current pulses that literally force current and energy into the battery.  Then you have a reconditioned battery, success!  The battery now accepts charge and behaves as a normal battery.

But what then?  That's the question that I have never seen raised, and I was exposed to a very wide swath of all things Bedini at one time.

Here is what I suspect:

The "reconditioned" battery will have a very limited number of discharge-charge cycles where it operates normally.  Then fairly quickly it will go "dead" again.

It becomes a cycle of diminishing returns:

Battery    # of recharge cycles

New                    250
1st treatment        30
2nd treatment       20
3rd treatment         8
4th treatment         3
5th treatment         0.5

The "reconditioning" is very limited in benefit in real-world usage.   The whacking of the battery with pulses of current "finds" some "new channels" for battery reagents that were "hiding."  However, they have a limited amount of serviceable usage in them.  The entropy of the battery chemicals is still increasing.  In plain English the chemicals in the battery are still decaying into useless mush.  Pulse charging a battery is just a temporary fix that "stirs up the mush" in the battery to find some remaining "good stuff."

I will repeat this is all my feeling.  In one form or another I think many of us have observed this type of behaviour in our cell phone batteries, or when you played with a battery-operated toy as a child.

One thing for sure, the whole business of "going up in levels" in the Bedini program is all based in reporting consecutive higher voltages in your destination charge batteries.  NO measurements of battery ENERGY, just stupid measurements of voltages.  That's retarded and people jump through those hoops.  They end up thinking that a Bedini motor is the real thing, without ever doing a strict and scientific regimen of battery ENERGY measurements.
