Below is another try, I'm still working out the cheap way to build the thing that doesn't leak, I'm still waiting for the glue to dry at the bottom, and will pour some down the sides tomorrow. Testing it it was getting 13.7volts / 37cells is 0.37/cell. I've order some Titanium sheet, 0.2mm thick instead of the Stainless steel(one hell of alot cheaper), and are planning on using this one to do some test with. The goal if it works out in a month or two is to have 100 cells with 5mm thick Al and Ti sheet, which should get around 0.7volt/cell. The circuit board in the below picture has 14 50F caps in series with 100kohm resistors to balance the charge, at 3.5F I'll try different duty cycle switch times and load resistance. The test with 1F cap in 1 sec reached 0.09volt with 8 cells, making the resistance per cell about 112ohms(I think), will be trying 1ohm up to 1000ohm. With the circuit board, each 50F cap is connected to 3 cells, which should make the ESR over the cap range 336ohm.
I'm moving farther away from electrical means to melt Fe3O4, if I can electrolysis water into hydrogen and oxygen then recombine it with off the shelf gas cutter tips, use the flame to heat the iron oxide and when hot, add more hydrogen into the mix to displace the oxygen in the iron, would probable be the best way.
EDIT I should get some test data tomorrow, the glue is almost dried.

Well this was almost a complete failure, the caps when charged to 5.53volt take 1min to drain to 2.05, it then takes 30 mins to reach 3.09volt, it settled at 4.27volt about 12 hours later. The think has leaked thought :) .I think the resiatance per cell worked out to 2.94kohms(It keeps changing.... , don't know weather its the battery or lack of understanding with the capacitor charge/discharge cycle).
Anyway, I'm at a lost of what to do next, apart from different salt combinations, or more battery's in parallel, each cell should be putting out 1 to 0.1watt, and was hoping the scaling of the thing should make a decent long term lead acid battery float, or hydrogen source.
This is the last post from me, unless something majorly improves.

How do you melt Fe3O4
