In high-power mechanics, electro-plasma was a super-energized plasma used to transfer energy from a central power source using plasma conduit transfer. Extremely high-powered warp plasma or drive plasma was used as a plasma stream to power the warp drive of a starship. Warp plasma was usually produced inside a dilithium controlled reaction assembly, where intermix between matter and antimatter occurred. On Federation starships and outposts, as well as those of other major spacefaring species, electro-plasma was the main power transfer medium.
