[one][two][three] He believed that the Electrical power was stored as being a demand inside the carbon pores as within the pores in the etched foils of electrolytic capacitors. As the double layer system wasn't acknowledged by him at time, he wrote from the patent: "It's not necessarily recognized just what is going down from the element if it is useful for Electrical power storage, but it leads to an especially large capacity."

This was an SCR, but rated at hundreds of amps. One of several terminals on it was a braid which was heavier compared to the wire going to the starter on your vehicle. Several evenings later on I had my device designed. A tub of caps along with a the massive SCR in addition to a pushbutton swap. You hooked the caps approximately a bench power source and slowly ramped the voltage up to about 4 plus a 50 % volts. I'd a few sets of heavy wire and large alligator clips and these went to V+ and ground within the board in a few sites. You disconnected the power supply, took a deep breath, and pushed the button. More often than not the shorted unit would de cap itself and it’s smoke would occur out. I set really some of the shorted ones with that setup. I continue to have among the SCR’s while I in no way did use it as a paperweight.
