Extracting uranium from seawater as another source of nuclear fuel

Oceans cover most of Earth's surface and support a staggering number of lifeforms, but they're also home to a dilute population of uranium ions. And—if we can get these particular ions out of the water—they could be a ...

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way.
