MAE-East still no generator


  As a few folks have pointed out, my less than eloquent
  explanation of why AC is more economic than DC over distance is
  not as accurate as it could be. I could argue what I meant as
  opposed to what I wrote, but I'd still be a bit off :slight_smile:

  Regardless, the point still stands that there's nothing inherently
  "modern" about AC as opposed to DC.

  The larger issue is having the appropriate pieces of
  telephony/routing/switching backed up w/ a reliable supply.

  Or mischievous hands moving power cables around :slight_smile:

] The real reason that AC is more efficient to transmit is that transformers
] work on AC, and that means you can, with little effort, trade amps for volts.
] Then you get to transmit the power at high voltage, but low current draw.
] That means thin wires (saves copper) and less resistive loss (saves energy).
