    Oslo and Trondheim (and possibly other Norwegian cities – I haven’t been to Bergen) also have congestion charges of this type – possibly the original source intended to say there were only four EU cities with congestion charges? (Norway isn’t in the EU).

    This isn’t new but I hadn’t heard of it – some cowboy geoengineering researcher dumped a pile of iron into the Pacific Ocean off the Canadian coast, in contravention of bans, to find out whether any CO2 was sequestered.

    Idiot.

    As far as the energy-storage thing goes, I’m really not sure of the value aside from a publicity stunt. It’s not quite the case that anybody can stack a pile of lithium-ion batteries in a room and have an energy storage system, but it’s not exactly rocket science.

    Personally, I suspect lithium-ion energy storage, if it is to be adopted, will mostly be adopted close to the end use.

    The problem with EV’s charging swaps is that they may be replaced by much faster battery swaps.
    For example, the prototype TESLA battery swap demonstration took about 90 sec. Renault also has a fast battery swap system.
    Another game changer is the aluminium air battery This is a non rechargable battery with an energy density that about 100 times greater than lithium ion. A 25 kg battery gave a range of 1600 km on a Peugeot test car. Provides a low cost, low weight back-up for an urban vehicle with a rechargable battery that handles the normal daily trip.
    The other thing that could affect the recharge industry is low energy consumption EV cars. They may have much smaller batteries that don’t require high amperage recharging.

    Robert @2, that makes me wonder how many tonnes of iron, in the form of dust blown from the many iron ore mines in Western Australia, most of which are not far from the coast, and from the ports along the coast where the ore is loaded, end up in the Indian Ocean each year.

    It’s got to be a hell of a lot more than 100 tonnes.

    What’s the story about algal blooms off the Western Australian coast?

    Interesting, GregM.

    1) For millenia, iron-rich surface dust has been blown out to sea by breezes, storms, willie-willies, etc.

    2) As for anthropogenic effects, these could include mining, vehicle dust trails, cattle stomping and wild fires.

    I wonder how the total iron mass transported by the likes of 2) compares with the total for 1), on an annual basis?

    I tend to agree with you Robert that the Lithium Iron battery and its derivatives are less likely to be a long term solution.

    But storage is important. There just might be far better ways of doing it. That is why I like nearly everyone else got really excited about

    A carbon based solution has got to be a front runner in the storage race.

    As a complete aside I have recently discovered through Sean Carroll’s web site, Preposterous Universe,…….

    Give it a fly and watch the comic-con video early. It is very uplifting,….creativity unleashed.

    PHD-Tv = Condensed knowledge in easily digested form. Sadly you still, ultimately, have to do the Maths, but it is so brilliant to have a better idea of where it is leading to.

    Did anyone else notice this blog entry at the Guardian a couple of days ago, which noted (apart from another dire warning from Hansen) a few other recent papers indicating that the 2 degree “safe” limit is quite possibly not safe at all?

    I have always had a hunch that the 2 degree goal had a large element of guesswork in it…

    Hot on the heels of the news that JK Rowling has published a best selling crime novel under a pseudonym. Is the news a US republican staffer has penned an award winning essay about the need for republicans to take the lead on climate change, under . . . , you guessed it, a pseudonym, to protect his job.

    The article back a carbon tax and takes a swipe at picking winners.

    I know folks like to poo poo compressed air technology on efficiency grounds and I’m not edumacated enough to argue the finer points so I don’t.
    That said, Lightsail Energy project seems to tick a few boxes.
    At the very least Bill Gates has lent his name ( and a few coins I assume ) to it.

  11. Jumpy

    And if you have some compressed air laying around at home why not take 10 seconds to charge up one of THESE and have some fun. :)

    I’ve been keen on considering the schedule feasibility implications for mitigation policy of the permafrost bomb for some time now. It’s sad to see that I wasn’t worrying needlessly. ;-(

    Greenland ice sheet is actively de-glaciating.

    7m of sea level rise. I guess it is just a matter of when.
