Microfusion generator

A microfusion generator was a form of technology that was essential in the lives of the Enarans during the 24th century, on par with a communications interlink.

Jareth once noted to his daughter Korenna how hard it was to relate to the Regressives, a group on Enara Prime who used little more than the most primitive technology, including such luxuries as microfusion generators or communications interlinks. 

In the Federation, microfusion generators were found aboard starships. While initiating the impulse pre-start sequence, it was necessary for the microfusion generators to be on line.
