    Is this the same as the Carrington Event from the 1800s?

    Get a big enough CME hitting Earth and we’re back in the early 1800’s.

    Another Carrington Event might teach the world a lesson about what life without reliable electricity would really be like.

    Imagine power blackouts lasting months!

    Is this Tony Abbott’s fault?

    Is impossible!!! IPCC climate scientists in their ineffable wisdom have told me the Sun has no effect whatsoever.

    They set solar variability to 0.05 W/m2 versus 2.29 W/m2 for dastardly greenhouse gases. They had to or it’d be obvious that most of the temperature rise is actually due to the Sun.

    Bruce, Bruce, Bruce…please keep scientific facts out of climate change / CAGW discussions. There is no room for that sort of biased information.

  9. I wouldn’t be panicking too much. I expect it would take a lot of energy to do more than put some static on your radio. If your car acts up when driving past that TV tower in Artamon, then it may be vulnerable. 🙂

    Most modern devices should be quite resilient since they have to (in particular) meet EU standards. I imagine the problems from the Carrington event were on primitive Morse code wires using an earth return. That space between the wire and the ground is the most vulnerable aspect for interfering electromagnetic waves. In comparison, our HV transmission lines carry balanced loads that cancel each other out in a relatively compact area and your delicate electronic circuits are protected by various measures, assuming they’re not cheap Chinese rubbish.

    A good fraction of remote area power lines, connecting back to the grid, are Single Wire Earth Return, with a step-down transformer at the end of the line, and then a local 240V single phase circuit around town.

    They drop out all the time, and that’s without the Carrington event … so the townsfolk are typically comfortable with the idea of blackouts. The question is only whether the extra AC magnetic field pulses across those long wires will bugger the transformer, or hopefully the normal circuit breakers will trip, wait for a reset and come back up again.

    Even if the transformers can hack it, having a bunch of SWER lines tripping in and out all night is going send the control room guys dialing up Jimmy Brings.

    Tel, your reply to Nelson highlights for me how fragile the whole system is. And it’s going to get a lot more fragile from now on.

  14. Although there’s different levels of fragility. The SWER problems are small in the overall scheme of things (even if inconvenient for those involved); it’s the statewide ones i worry about.

    I survived the Great South Australian Blackout (on a holiday trip, LOL) and now have a smart battery box that’s hopefully sufficient to keep the fridges alive in addition for use when camping. Yet to succumb to purchasing an internal combustion solution with the maintenance it requires.
