Why the Grid Still Runs on AC When DC Won
Thomas Edison lost the war of the currents because you couldn't change DC's voltage — but modern power electronics can convert DC at eleven hundred kilovolts, and HVDC lines now lose half as much power over distance as AC. So why does the grid still run on alternating current? This episode traces the transformer that decided a century of infrastructure, the 2012 circuit breaker breakthrough that made DC networks possible, and the four practical constraints that still cap DC voltage today. The answer isn't physics. It's a century of installed copper. Episode 5757 — myweirdprompts.com/n/5757…
