If we discover room-temperature superconductivity and it is industrial-scalable, I could see DC taking over AC transmission lines.
But right now, resistive heat losses make DC a silly solution. That’s why we rectify only when the energy reaches “the edge.”
- thehappypm 5y agoOhms law is the same for AC and DC at any given moment in time. That is, in an instant where an AC voltage in a wire at 120V, it will have identical resistive loss as DC voltage at 120V.
