@ Grumpy and All: The above mentioned cells can and do charge both caps and batteries, at not cost, and do so for a long time, whether they are electrochemical, galvanic, petrovoltaic, or just normal electric current, who knows. But the prospect of having a sort of power supply (similar to using a solar panel) but using something like these cells that don't need sun, and don't run down either, is what I'm working on now. The idea of utilizing just voltage, and no current is intriging, if possible. Especially without draining the source of that potential. But I have not seen it done, yet. I have heard talk of it, but not a device, or battery, or power supply of that sort. Have you???
