Common batteries are free energy sources

[allcanadian]

Hello PG46
I read the last page, my post from november, it seems like years have passed since that post. I have come so far in such a short time thanks to this forum.

Anyway, I did the tesla battery switch a few years ago and it does work but it has limitations.
Power is one, heat/radiated energy is the enemy here, you need short duration pulses and a low duty cycle, meaning space your pulses out so the coil doesn't get hot, = low rpm
Tesla realized that the higher the working voltage , the lower the losses such as resistance heating, and that more energy could be recovered.
You never return energy to the source if possible, you move from high potential(voltage) to lower potential. Once you get this you can move on to better alternatives, like the coil acting as a DC-DC converter or buck booster- then it converts the source voltage to a higher voltage on the fly and can be returned to the source.

Here's a very intersting lesson in perception, that nobody has considered that I know of.

You pulse 24v(2-12v batteries in series) into the stator coil of a motor, this is travelling to a 12v battery. So 12v(24v minus 12v) at X amps(watts) went through the motor into the 12v battery, then when the switch is opened a Bemf spike is sent to the low potential 12v battery so you get all your energy back right? not really
Where is the other 12v?

If a Bemf spike of let's say 40v is sent to the 12v battery then the minimum voltage allowed into the battery is 12v.
So what happened to the other 12v? from 12v to 0v that didn't go into the battery?
Because Zero volts is the lowest potential of the system and anything under 12v can't go into the battery, where is it?
Heat
A 1000v system losing 12v Bemf is nothing, a 24v system losing 12v Bemf(1/2) is not.

@ Triffid

Thank you for bringing this thread back into the fold 

Even if you only meant for it to be a link back it's been an interesting read on a thread related to the Tesla switch and people's experiments and experiences with this circuit from back then until now (2006 - 2008) ! 

@ allcanadian

I've been wondering for years whether any of these supposedly "Tesla switch" circuits have ever worked for anyone, have you ever had any truly good results such as the Electrodyne experiments where it "is" claimed there was a 3 year usage on their setup driving a motor and the batteries were tested at the end of their experiment and didn't show ANY wear on them???

Without a full disclosure on the full material list and methodology to this experiment I'm afraid I'm still in the dark and apprehensive to try it because if mis configured or mis timed, it could blow up

On a side note and not meant to derail this Tesla switch type thread, has anyone ever produced a successful replica of John Bedini's Energizer design with the battery/generator/flywheel/magneto setup?  Page 28 of the Free Energy Generation book if you got a copy 

I'd really like to try it on a small scale if it's possible but so far I haven't seen or heard anyone claiming and showing such a beast, is possible?

I recently was nudged towards reading this thread and was intrigued.  I've recently been playing with the Imhotep- Bedini fans and was looking at ways to use the output bemf for something other than just charging another battery.  While researching DC step down (or up) transformers such as a spark/ignition/inductor coil transformers I found science project material on making your own.  These used the magnetic field of the coil itself as a solenoid for a mechanical switch that was pulsing the input power.  Since the mechanical switch does not have the electrical losses of the transistors and supporting circuitry I thought it would be an interesting alternative to those components in the Tesla switch - Current Siphon system.  I think someone mentioned the need for mechanical switches and purely inductive loads earlier in this thread (allcanadian?) so it made sense.

I reduced the circuit to just the four switches that change battery pairs 1+2 and 3+4 from series to parallel and visa versa.  That way I could run the entire circuit from a single 24V 4 pole Omron relay which I "acquired" from work.  I worked the spring a bit to make it switch easily at 9 volts.  I purchased 4 x 9V NiCds from Radio Shack this morning.  (Side bar - I ran those uncharged batteries up to 9.7 volts on the Imhotep-Bedini fan before conventionally charging them.  They settled at about 9.4 V after conventional charging.  What's up with that!?!)  I wired up the Current Siphon through the single 4 pole relay using the relay coil as the load (pure inductive load).  i was shooting for a self oscillating relay setup.  At first it would only bounce off of the normally closed set of contacts, interupting the circuit and the power to the solenoid and never make the other set of normally open contacts to flip flop the battery arrangement.  I finaly tried putting the big cap from a CFL (another Imhotep replication project volunteer) across the "load" solenoid to make sure it crossed all the way over to flip the batteries.  It works!

Since I am only switching the batteries and not the load the load is seeing a +9 --> -9V DC pulse.  I figured, what the hell?  Gotta start somewhere.  Plus, that's half way to usable AC...

The one problem I'm having is that the switching is not balanced.  It stays on the +9V side almost three times as long as the -9V side.  I guess that could be adjusted by changing the cap?  I'm not an EE so I'm just working with the basic knowledge of each component type.  What do I adjust, and in what way, to get the 50-50 balance in this device?

A few more bits of info:

The Omron relay solenoid appears to be a DC transformer coil and so has two windings.  The second winding is used to kill the bemf by putting it through a resistor and LED ( for visual switching confirmation?).  I cut this loop to see this "output" vs. the input.  It mirrors almost identically the input but at 1/10th the voltage on my o-scope.

The entire circuit is not running perfectly smooth.  You can hear (and see on the o-scope) when a contact misses.  But it's damn close for a first try!

A few more questions:

Could the relay benefit from something to supress arcing?  If so, how to do and keep this solenoid load purely inductive?

Am I messing up the "pure inductive load" with the cap necessary to switch the relay fully?  Do I need to have two relays or an 8 pole version to do this properly?

PS.  Hi Al!

One more question I forgot...

I have no diodes in this system right now.  I figured the possible hazards due to omitting them were low since I am only working with 9V 120mAh NiCds.  I'd appreciate any input on this subjects as well.
