How would this not work?

[turborunner]

Couldn't somone build the tesla switch and use one of the batteries to supply a say car audio amp(1500watt @ 40amps). Then use that load to power a tv and computer. The tesla switch keeps the batteries charged so the amp has continuious power with no outside input, right? How is this not simple elementary or is it?

Hi turborunner, I don't think it will work unless you can find or build a Tesla
switch that can keep a battery charged while it is providing 40 amps, I
haven't seen one of those yet.

I don't expect to see one any time soon either. When a lead acid battery is
powering a load there is a chemical reaction happening to give up charge and
when charging the reverse happens, the battery cannot do both at the same
time.

If you watch a lead acid battery when a load is applied the voltage will drop
until the battery meets the needs of the load then as the chemical reaction
continues if the load is not too much the battery voltage will then rise as the
reaction in the battery catches up to the load placed on it.

Incidentally that lowering and rising of the battery voltage under load is what
catches a lot of people out, it's perfectly normal.

How Lead Acid Batteries Work

For example, the starter in an engine will typically quickly outstrip the
capacity of the battery to keep cranking it for any length of time. Hence the
tip from mechanics to wait some time between engine start attempts. Not
only does it allow the engine starter to cool down, it also allows the chemistry
in the battery to "catch-up". As the battery comes to a new equilibrium, its
available capacity increases. A very elegant equation developed in 1897 by a
scientist called Peukert describes the charging and discharging behavior of batteries.

The only way I can see to use a battery while it is charging is if the load
power is less than the charging power so that the battery is only taking and
the load is powered basically from the source charging the battery, in that
case the battery can become a voltage regulator and a storage cell, then
when the charging source is removed the battery can supply the load as
normal. Just like in a solar system. The panels themselves without a battery
would be unregulated.

Oh thanks! I thaught I must have been overlooking the obvious, back to the drawing board.

My understanding of the Tesla switch is that it does not function as a closed loop system, as in conventional systems where a battery supplies a load, and in the process, is drained. Unlike the closed loop system, the Tesla switch is an asymmetrical system which keeps the dipole open and allows a continuous influx of radiant energy into the system. This continuous influx of radiant energy is accessible via the lead-acid battery as electrical potential. Once you've killed the dipole, however, conventional electrodynamics kick in, and you've gotta charge what you've drained away. The question is, then, how to build a Tesla switch that is an asymmetrical (open looped) system.

follow the clues

time.

In my process of documentation I've read somewhere that you need to (of course) pulse the circuit. That means the circuit is open much of the time and only closed for the very short periods of the pulses. From other materials I've read that the open loop should last for about 2 to 3 times the amount of time of the closed circuit loop (considering that you can't pulse only for an infinitely small moment). Also, the functioning (pulse + open loop) shouldn't have a frequency of more than 800Hz. I figure the extra time is needed for the absorption of the radiant pulse into the battery.

SO, a compromise (I've ordered wire and am going to test it out) may be made so that the battery would pulse at higher frequency, but the back pulses should be of no more than 800Hz. That can be easily achieved with a low-pass filter and a measly diode. However, the part of the pulse that would not have yet been absorbed would be thrown back into the system. But that may be a good thing because that pulse would (I think) be of higher voltage. And higher voltage would cause even higher voltage feedback. Like I said.. gotta test it out. I hope voltages would be manageable or else I'd lose a transistor and I'm pretty lazy in changing it.

People should consider the Tesla Switch with higher regard cuz I see great potential.. literally and figuratively.

@ WeISs

Maybe you should read all 137 pages of the "Use for the Tesla Switch" thread on this forum and you would realize it is not as easy as you think. We have a lot of really sharp people on this forum that have worked on that project for years and still haven't gotten a system that does all we want it to. And if you really don't like changing transistors maybe you should consider another hobby. Because you will have to change plenty of them if you decide to continue with the Tesla Switch.

Of course, you are right. And I should be reading the thread. I didn't get around to it because of the enormous size, but now that you've mentioned it I'll make a point of it. Before that I'll use the knowledge that I already have (basic stuff) and I'll try some of my own designs first.. so I won't be biased. I'll also post my shame if nothing comes of it.

And the results I get in my tests (good or bad) overshadow my lack of pleasure of replacing transistor corpses. And you should see the list of my other hobbies >

Thank you for pointing out "Use for the TS"

One other note is that car audio amps are commonly way over rated in the power output. That 1500 watt amp is probably lucky to put out 500 watts if even that. I'll bet you have never seen a scientifically done test that validates the power output of a car audio amp as being equal to it's claimed power.

Also coverting audio power back to usable AC power would likely involve large losses.

IT IS POSSIBLE!!!! Don't let anybody tell you it isn't.

Use a 100 amp hour BatCap. The 4 primary batteries in the switch will need to be in the range of 400-500 amp hour. The BatCap is designed for this kind of use and handles it perfectly.

Use the primaries to drive a transformer and dump the output power into the batcap. You'll need a 500 va or better transformer.

A circuit very similar to this with 100 amp hour batteries has been running for 4 months now in my garage running an 8 amp load. No signs of quiting.

Good Luck.

Great news!!

Hi Matt,

That is great news. I am glad you got it going that well. The best I have ever done was to keep it going for a several days lighting only some Leds. When the weather cools down and I have more time without all the yard and garden work I want to wind that transformer and try to get that going. I am still playing with the 3BGS circuit when I have a little time. If nothing else the 3BGS is a really good way to restore dead batteries.

Later,
Carroll

All you need is 6 batteries. 2 discharging, 2 charging, 2 resting.

When I get some more time, I have been busy too, I'll finish the Inverter circuit that runs with it. Constant 120 vac pure sine. Everything including drive circuit in one package.

Can anybody say "For Sale"??? LOL
