$210 Billion In PV Would Reverse Osmosis All the Rise In Sea Level

    If the volume of sea level rise is 0.2 km^3/hr or 350 GW to power the
    reverse osmosis pumps or about $210 billion in PV at $0.60/watt.

    The water can be injected into the aquifers to buy some time.

    There are other costs, i.e., canals, etc. but this is faster and
    cheaper than sea walling every port city on the planet.

    Cool idea, but then you have to figure out what to do with
    all of the brine.

    If the volume of sea level rise is 0.2 km^3/hr or 350 GW to power the
    That will resalinate the ocean from all the fresh water from the ice
    melt runoff.

    Basically the transfer is fresh water from ice to the ground.

    Every enthusiastic supporter of free marketry knows free marketry
    ain't possible without _someone_ spending.

    With seaquestration, however, we spend a whole lot less.

    It's an interesting idea, but I'd like to check the figures. Here's some
    info on the economics-
    http://www.oas.org/dsd/publications/Unit/oea59e/ch20.htm

    Desalinated water is much too valuable just for agriculture, there are
    over 1 billion people in the world without access to safe drinking
    water. Combine the two and you have a geoengineering project that makes
    sense for a change.

    If it was me, I'd irrigate Spain, N.Africa, etc, with some of that water.
    For a couple of million you could flood the Qattara Depression - it's only
    about 50km from the Mediterranean coast - using windmills and ditches.

    That would;
    Lower sea-levels a little.
    Create flamingo habitat.
    Create a Dead Sea type tourism facility.
    Create a salt industry.
    Reduce regional temperature.
    Increase rainfall somewhere a little.

    ....

    Ha! I've been saying this for years, and today I find people have actually been
    looking into it.

    Of course wikipeadia goes full-stupid, talking about nuclear explosions. Tsk.

    Put it back in the sea. The sea can only get so salty, after which point the
    salt precipitates out and falls to the sea-floor.

    So send the water to a city in return for sewerage: treat the sewerage, and
    you've got soil-conditioner and irrigation water.

    It's a great idea, but using these figures -
    http://www.oas.org/dsd/publications/Unit/oea59e/ch20.htm
    and a melt rate of around 100 km3 per year, you'd need at least $210
    billion just to build the desalination plants, let alone the PV plants.
    I'd still have to estimate how much PV capacity is required.

    The other problem is that it does nothing to actually stop global
    warming. That means that on the BAU model you can expect the melt rate
    to continue up to the icecap tipping point, after which it starts to
    shoot up exponentially. That means that however you cut it, in the long
    run you're going to have 70 meters of water level rise, regardless
    whether it's salt water or drinkable.

  13. PVs are unpremeditated expanses of urban heat-islanding, although
    there are some that also heat water. anyway,
    Morner's datum shows that there is no sealevel rise,
    beyond "eustatic rebound from last glacial maximum," and
    he ought t'know.

    "global" warming, it is to snicker.

    Aid package to be voted on totaling $60 billion. If Toronto had
    been hit harder that Richard Anderson dirtbag would have been
    screaming for relief money.

    If the volume of sea level rise is 0.2 km^3/hr or 350 GW to power the
    Most of it needs to be injected where it won't evaporate and will help
    prevent sink holes.

    If the volume of sea level rise is 0.2 km^3/hr or 350 GW to power the
    All of the water doesn't have to be desalinated. In California it's
    illegal to inject anything into the aquifer, however, in some places
    the geo thermal brine is so toxic it might not be hard to get the
    state to provide a varuience.

    Consider that a acre foot of R.O. costs a few hundred dollars in
    electricity at today's rates and an acre of berries and many other
    crops can fetch $40,000.

    Some farmer from Salinas was telling me farm land in Salinas _rents_
    for $60,000 / acre - year. Maybe he meant a quarter square.
    That calculates from the 8 MPa pressure needed for R. O.
    Before we discuss point C the IPCC _better_ come up with a plan to get
    to point B.

    Also consider conventionally [read: expensive] powered R. O. costs
    several hundreds dollars/acre foot while many crops bring in at least
    an order of magnitude more money / acre.

    If the volume of sea level rise is 0.2 km^3/hr or 350 GW to power the
    Too many unnecessary conversions and losses.

    If they can get the price down on batteries just go straight from
    solar to the battery.

      if you pump sea water into the aquifer
    Leave it down there.

    A lot of ground water is toxic, Cd and other heavy metals.

    If the volume of sea level rise is 0.2 km^3/hr or 350 GW to power the
    What is the CO2 produced/watt of PV?

    And while you are at it, tell everyone the elevation of Al Gore's
    mansion above mean high tide.
