  • Electricity network requires that production and consumption are always equal. If there is too little production, the frequency (Hz) goes down and if too little consumption, the frequency goes up. If frequency goes too far every electric device pretty much breaks.

    This is why there is automation in the network that tries to balance the network (reserve production and consumption). BUT if shit hits the fan, and frequency goes too bad, it automatically takes load off or production off the network. This often causes domino effect, you take load off, which causes over production, and again you take production off and loop is ready. In minutes the whole network falls like domino blocks, one by one.

    There was lots of luck (and probably skill and preparation) that they were able to stop it. Main land Europe from Portugal to Turkey is one big network.

    Cold starting whole Europe would have taken week. You need to start small islands, and connect them together slowly. Balancing load and production.

  • No no, please don’t do this without eye protection. I did some grinding without eye protection, didn’t hurt or anything, but day later doctor had to drill metal particles out from my eye balls.

    0/10, would not recommend

    and they said that I cannot get MRI ever again, because some small particles might be still inside and magnet can pull them out. Fun stuff.
