Electrode

The electrode melted and mixed with the steel.

The negative electrode is usually made of carbon.

The positive electrode is called the cathode.

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).

Inside that murky vial, attached to the negative electrode like barnacles to a ship's hull, an unusual type of bacteria feast on particles of organic waste and produce electricity that is captured by the battery's positive electrode.

In an interview six years ago, Henry Loomis remembered an experiment he took part in when he was about seventeen years old. Henry slept in a sound-proof room with electrode devices attached to his head. Alfred Loomis was nearby with a microphone device. He told his son in a soft voice that Henry's favorite object, his boat, was on fire. Henry Loomis jumped out of bed to save the boat. This experiment and others helped Alfred Loomis show how emotional upset could change human brain waves.
