An embodiment of a hardware module for confining a plasma of electrons and ions in a nuclear fusion energy generating device. In this embodiment, a complete energy generating device is composed of six identical modules, spaced close together in the shape of a cube. The modules confine the plasma inside a cubical enclosure, compress it to high density, and heat it to high temperature. The embodiment of the module is robust and easy to maintain. Other embodiments are described and shown.
