I beleive that heat is the key,but not neccesarly in that it can be used for gain,if we could send all generated heat to a specific location,capture it, turn it into something usefull, dissipate it I believe this is where the answer lies....heat, vibration,pressure and oasicilation,..they all seem to be the same thing........shylo

The heat is necessary when there is no chemical reactions, as it is the only possible source of energy.
Here we have redox potentials but without possibility of chemical reactions. Therefore this prevents a current to flow when we loop the external circuit at the electrodes. Nevertheless there is still a transition time during which current flows until the equalization of the potentials at the electrodes (then the cell is depolarized). This process is supposed to be endothermic and when we break the circuit, the environment heat allows for the re-polarization of the cell by a reverse process. It is what I understand from Karpen's patent and other papers.

I tested cells with different metals in a saturated solution of sodium hydroxide. The metals were chosen so that they don't react with NaOH.
The potentials were between 0.3 and 1.2v. The best result was with a carbon anode and a cathode in a ferromagnetic metal (probably steel or iron) whose the whole surface was coated with an inoxidizable metal. I don't know what is this metal, it has rose and green iridescence -see photo-.

The voltage goes up to 1.2v. When the cell is charged with a 100 ohm resistance, the voltage drops instantly to about 0.8v (= 8 mA, 0.48 mW). Then it slowly drops to 0.21v after 1 mn. If I open the circuit at this moment, the voltage increases. After 1 mn: 0.62v, 3 min: 0.73v, 5 min: 0.80v, 9 mn:0.92v

Apparently there is no chemical reaction, the electrolyte and the electrodes remain clean, nevertheless it can't be formally proved because the involved quantity of electricity is too weak.
The time for the cell to recover its full voltage is very long relatively to the duration of the voltage drop when charged. 

So we can say that Karpen's battery works. All this confirms Karpen's observations, but also his difficulties to prove beyong any doubt it is a Maxwell's demon. To prove it definitely, we need temperature measurement (which should drop when current is drawn), but the current is too weak to expect for an effect.

Now we have to increase the current and to shorten the time for depolarization but I don't know how.

Does it help if you stir it?

Try larger surface area and/or mass and charging a low voltage cap.
