History

Discovery

The technology was developed by Dandéros Nélina in the year 1374 PN.

Usage

Utility

Spark jars are used when a mobile source of electricity is required. They provide lower voltages than fuel-based generators, but are far more portable. Depending on size and usage, a single spark jar can last between a few minutes and up to three days. It is also possible to recharge them by connecting them to an appropriate power source.

Manufacturing

The outer shell is made of glass with a sheet of zinc lining its inner walls and folding around its outer rim. Nested inside is a smaller pot of baked clay, which in turn houses a copper rod. Both hollows are filled with acidic solutions. Finally, the jar is sealed with a wood disc drenched in Hénéphgýa resin, leaving the tip of the copper rod sticking out.
