Why European Clocks are Running Slow, and British Clocks Aren't

  • Many people sent me this story: it covers my favourite topics of power grids and temporal anomalies. But when the mainstream press have already covered it, how could I add something more? The answer: by adding another pet topic, Unnecessary British Patriotism. And a teasmade.

      mystica5551212-subs According to an article in, IIRC, Scientific American a few years back, some scientists have proposed putting combination pipeline-cables underground to ship both liquid hydrogen and DC power. The innermost layer would be made of a high temperature superconducting alloy that “only” requires liquid hydrogen; around this would be a pipeline carrying liquid hydrogen produced by electrolysis at a hydroelectric plant (which someday would have a fusion reactor powered by the deuterium concentrated by the process, in which case only the water source would be needed, not the cataract). The plant would ship the two products together: hydrogen to be packaged as portable fuel (or to run fuel cells at the receiving site), and electric power.
      I haven’t heard any more about such a project, so I don’t know whether it’s practical (yet). But there are superconductors that operate at liquid nitrogen temperatures, and one day there may be “room temperature” superconductors.

      +Allan Richardson no, not superconductive as that requires very very cold temps which would take rather ludicrous amounts of both liquid helium and power to achieve. On the order of Large Hadron Collider size. At least the one to the Netherlands... France, only a semi-ludicrous amount.

      Actually, you've got that backwards. Technically, for the same average voltage, DC works better then AC. A phenomenon called skin effect concentrates oscillating current towards the edges of a conductor, reducing the cross-sectional area, and combined with the natural inductance of the wire, raises the resistance.
      However, where AC wins over DC is in the ability to step the voltages up or down with purely passive components - transformers. Which is a major consideration for distributing electricity, especially to the individual users. A single, point-to-point high-voltage transmission line, however, can just offset the cost of switching to and from DC by the energy saved in vastly reduced transmission losses.

      Sam Dettle HVDC (High Voltage Direct Current) is more efficient than AC, but it's also much more expensive, so over long distances, the cost-to-benefit ratio tips in the favor of HVDC over AC.

    As of today, there is an underwater power cable, called Nemo Link, connecting the British and Belgian grids, the latter of which is also connected to The Netherlands', France' and Luxemburg's grids, etc.
    So, in the future, similar cases as the one set out in the video would likely no longer have the same effect.

    50hz is a lot less efficient for AC power delivery than 60hz, the decision to base the british and european grids on 50hz has cost 100's of billions to trillions in waste over the history of electricity.

    These cables bring to mind a lot of questions:
    1) Why are there cables connecting the grids?
    2) What is the energy loss to use DC instead of AC (HS science always told us that AC is much more efficient over long distances)?
    3) Why was DC chosen for these Cables?

    So at least, thanks to your Queen, the Brexit will be on time with 50 cycles , whilst for us continental Europeans your Brexit will be 6 minutes too late in our deep-felt perception of time.
    Anyways, wish you luck with your Brexit, as on the continental side the EU politicians are destroying , what is left from the good old times, at much higher rates and frequencies as 50 cycles.

    Southern California started with 50 cycle equipment, and to hook into a grid they had to switch to the 60 hz everyone else was running. So the power company opened a shop where clocks could be brought to have their gears changed out for free.

      Kieran. Yes, it does have an atomic clock signal. The whole world has access to atomic clocks. It's just that some manufacturers like to save money by not installing an atomic clock receiver; they use the power grid cycle for accuracy instead (cheaper) - and, as Tom says in the video, it's accurate enough for most people.

    One documentary I saw several years back said that the (continental "lower 48) US has three major power grids: East Coast, West Coast, and Texas. There are several links between the East and West, but none with Texas (at the time of that program). Since Texas was an independent country for about a decade before joining the US (then attempting to secede and join the Confederacy, then rejoin the US), they still think of themselves as a separate nation from the rest of us. Even though this was also true of California (hence the Bear Flag) and Hawaii (the only US state with a former royal palace), only Texas acts so entitled.
