AC for simple long-distance transmission...
Except for underwater cables, where it can cause unacceptable
transmission losses.
How does immersing a 11kV AC cable in water increase transmission
losses? This isn't a joke question, I can't see how the medium
surrounding a cable changes the action of the cable itself, other
than cooling effects.
