I thought it was more the issue that you cannot phase lock France and

you have to do that, might as well transmit in DC too.

Not saying your reason is not a good reason - I just thought it was a
secondary reason to a fairly immutable primary problem.

No. I visited the first link to france at the UK end and the issue is
primarily one of losses

'we can draw an arc for 30 minutes off the capacitance in that cable'

To drive that capacitance takes a LOT of out of phase current and that
suffers resistive losses.

Big ones


Drivel
Capacitance does not cause any losses.
It does cause phase shift and instability.
When the cable is under load it will actually help with phase shift.
Only resistance causes losses.

Where exactly is this arc drawn for 30 minutes and for what purpose.?
