A Plasma Generator is a Tau generator technology used to power the majority of tools, devices, settlements, and voidships manufactured or maintained by the Tau Earth Caste. A Tau Plasma Generator makes use of a nuclear fusion reaction to generate large amounts of electricity in the form of the high-temperature phase of matter known as plasma.

The Brachyura, a tiny and highly dexterous xenos species similar to Terran crustaceans who are a part of the Tau Empire and call the world of the same name home, specialise in the manufacture and maintenance of Plasma Generators used by the Earth Caste. Because of their small size and unusual ability for fine manipulation, the Brachyura are capable of the delicate movements required to assemble Plasma Generators of remarkably small size and efficiency for the Earth Caste.
