   A really interesting and informative video about High Voltage DC power interconnectors of the kind we have between Britain and France, Belgium Netherlands, Norway, Ireland and (soon) Denmark. Engineering with Rosie explains why D.C. is chosen and both the benefits/drawbacks of building even longer cables, such as the UK-Morocco link or even a transatlantic cable.

     @goatsarah @christineburns Comparatively short distance so trad AC is probably OK

     @goatsarah @ajlanes I can’t help feeling that the Morocco-UK link would be easier and quicker to do by transmitting through the Spanish and French land-based grids. After all, the east coast side of England’s grid (with most of the interconnectors) has become, at times, a fancy way of selling electricity between non-adjacent European countries.

     @goatsarah @ajlanes Whilst it’s not surrounded by water it is (a) surrounded by chalk and (b) running through a long reinforced concrete tube full of rebar, so the cable would have an impedance for AC similar to coax. But I agree that the need for AC synchronisation would result in having to build inverters at both ends anyway, especially for it to be bidirectional

     @goatsarah @christineburns wikipedia suggests it's DC. Not that it's sourced. If you have better info, I'll change it. https://en.wikipedia.org/wiki/Spain-Morocco_interconnection

     @goatsarah @christineburns Ah right. Afaict from a bit of googling, the cables which land at Tarifa are HVDC, the ones in Gibraltar are AC.
