The Csub is a small generator that converts an electric current into electricity.
This article uses an example of a Csob generator.
The Csub has been used in the past to convert electric currents into mechanical energy, but it has recently been used for generating heat.
The Csobs uses a simple, inexpensive, and relatively simple design that is easily adapted to other uses.
This tutorial explains how to use the Csober to convert electricity into heat.
