    Philip, it is definitely d.c. else there would not be a huge shed about a mile (1.6 km) from here.

    I can see how d.c. transmits power, but a.c. has always been a mystery to me, and probably always will be.

    I believe there are currently three interconnectors between the UK and France (IFA / IFA-2 / ElecLink) all of which are high voltage direct current (HVDC).

    The interconnector between the UK and the Isle of Man is the only undersea interconnector that I can think of that is alternating current (AC).

    One analogy I liked was a bike chain. You don't have to move the pedals very far to make the back wheel move (one link doesn't have to go all the way around before anything happens, it just needs to nudge its neighbour) - indeed where the wheel has a ratchet you can make the back wheel turn consistently in the same direction just by moving the pedals forward a little, then back by the same amount, repeat.
