I think this is loosely hidden technology, more relying on people to "not get it" to stay hidden.

I want to do a replication of Nathan Stubblefields 1898 American Patent #600,457.

What's you're opinion on the following?

I want to try replicating his battery because of an interesting phenomenon you can do with his battery and claims in the patten that he used it to get ~50 A ~50 V. He was under the impression that his battery was an energy harvesting system because of the amount of power he was getting....

I'm less convinced, I think it's just a really clever self-powered electro-magnets with directional control over the field and control over the strength of the field by controlling which taps are used and how much current is drawn from the galvanic reaction. Since the galvanic reaction happens over the entire length of wire in the coil the "effective" voltage applied to the coil is significatnly larger than what's available as "terminal voltage".

I was watching "laserhacker" test out his replication of the batter and show a bit of how it works and I get it now and I want to make sure.

Basically, the battery electrodes are the solenoid wires and you tap off of them so that the current flow during battery opperation harmonises and causes the soft iron core to magnetise.

The battery still only provides 0.9-2 V depending on the metals used and still only provides small short crcuit currents. The genius is that the entire length of wire in the coil is part of the galvanic cell and contributes to the current flow.

Now, you wrap a secondary around the primary as a "step-down" transformer and you draw power from the primary by switching it on and off to induce current flow on the secondary and you use the secondary as your main power source. There's still only maybe 0.1-0.2 Amp of current flow in the primary, but the inductance of the primary is really large because the coil is HUGE. The idea is that the "effective" voltage is what is being stepped down, not the "terminal" voltage.

What ends up happenning is that to push the same current through an equivalent coil at the same switching speed would need 1000s of volts, not 0.9-2 volts. So while you can only access 0.1-0.2 A @ 0.9-2 V of current flow through the galvanic reaction at the terminals, the "effective" voltage on the coil is much higher if you consider the summation of the galvanic reactions over the length of the primary coil.

Stepping down the "effective voltage" and using the secondary as the power source, you have an ultra-powerful, long lasting earth battery. The galvainc reaction happens slowly because it's limitted by the charge flow during switching, but the power from the secondary is impressive.

Any ways, that's assuming his pattent is accurrate.

Besides that is it logical that the entire galvanic cell should indeed produce voltage so it would actually kinda be different that simply trying to inject power into the electromagnet at the terminals is sound right?

Like the concept of "effective voltage" of the length of wires making up the primary?

The biggest issue to do the replication will be finding the right wire to make the solenoid-battery out of.

Any ideas?
