A typical heating element is usually a coil, ribbon (straight or corrugated), of strip of wire that gives off heat much like a lamp filament. When an electric current flows through it, it glows red hot and converts the electrical energy passing through it into heat, which it radiates out in all directions.
Perhaps one of the hottest areas in carbon research today, however, involves the miracle material graphene. Graphene is a sheet of carbon only one atom thick. It's the strongest material known while still being ultralight and flexible. And it conducts electricity better than copper.
