We don’t mean space-time continuums or matrices. Speaking electrically, of course, our modern consumption is mainly wired for alternating current as opposed to the direct current that dominated at the beginning of the power grid era in the late 19th century.
Direct current was more efficient at higher voltages, but alternating current was easier to step voltages up or down via transformers.
So, Nikola Tesla’s AC innovation won the war and has been the electrical infrastructure’s main mode of transportation over the past 130 or so years. Direct current was doing big work, but mainly on high voltage transmission lines outside the U.S. and in isolated projects.
DC isolation, however, is becoming a thing of the past in this era of energy transition. The devices rising to the top of the modern and future economic and technological food chains are almost all DC, such as computers, solar cells, electric vehicles, batteries and fuel cells.
