Cobalt-Pressed Electron Wafer

A Cobalt-Pressed Electron Wafer is a small energy-storage device created, produced, and utilized by the Bankashi. Typically abbreviated in most languages, a CPEW (or SEE-POO, to some less advanced individuals) is a rudimentary invention which relies on atomic decay and coherent electron prismatrices.

Construction
A CPEW begins its life as an electron prismatrix, a kind of physical matter woven out of electricity itself. The prismatrix must be uniform and symmetrical, or it will destabilize. In order to "capture" the prismatrix it is sandwiched between sheets of pure cobalt metal internally textured with an elaborate pico-scale meta-material. This procedure is the source of the device's name, as the electron prismatrix is literally "wafered," in alternating layers between the sheets of cobalt. The result is a small device, the size of a button or coin, that can be tapped for an extraordinary amount of energy. A CPEW is depleted when the cobalt forming its shell depletes into iron, at which point it typically falls apart, harmlessly.

Energy Storage Potential
While CPEWs are capable of storing and discharging staggering amounts of energy, they are not suitable for tasks which require large amounts of power all at once, or quick jolts. Similar to terrestrial batteries, CPEWs are useful for prolonged use, where low draw and moderate output is useful. If they are not subjected to adverse conditions, they may last several decades, however when put to use by Bankashi they typically only survive a few years at a time.

Use as a Form of Currency
The CPEW has seen use as a kind of coinage within The Bog. Its small size and usefulness as a battery make it perfect for trade and barter. Its utility frequently goes over the heads of most simpleton Bog Folk, who see it as little more than scrap metal. These items are of particular interest to the residents of Shrempton, who have taken to using them and experimenting with them.
