  3. The CAA's view. on Was Flight Ban Over Ash an Overreaction? · · Score: 1

    Despite Branson being an irritating beardy nirk, I do have a modicum of respect for him, and in this palaver he has generally done the sensible thing of shutting up about things that he doesn't really understand.

    The CAA have for quite some time (since 16th April) posted reasons for the discouragement of flying in volcanic ash, which cites this PDF from a 1993 publication. Which boils down to "ash fucks engines, windows, instruments and paintwork and can generally fuck your plane out of the sky".
    So, for a long time (since 1993, if not earlier) the advice has been "don't do that".

    Now, there's a general question of why the engine manufacturers, instrument manufacturers, and aircraft manufacturers didn't long ago get their communal posteriors in gear and come up with some more nuanced guidelines than "don't do it". Maybe something like "don't do it at more than one part in 10^15 of ash suspended in air for more than 10 hours of accumulated flight time before stripping down all the engines and replacing the pitot air-speed sensors" (numbers are for illustration only). And the general question has a general answer, "no one considered that the question was important enough to deserve more attention".

    There's also a failure of communication here too - us geologists have long (centuries) known that Iceland is a hotbed of volcanic activity, and we didn't think to slap the CAA (and international equivalents) around the face and ask them some awkward "what if?" questions.
    But then, we don't generally get the CAA calling us and asking what the consequences of a loaded jumbo jet crashing into a volcano would be. The two fields don't really impinge on each other. Except with a CFIT (when the Terrain normally survives better than whatever does the Controlled Flight Into it; "CFIT" is aviation lingo for "Controlled Flight Into Terrain", but dressed up so as not to scare the paying sheep in the passenger cabin), or as we now know, with a volcano erupting close enough to a major airways nexus for the ash cloud to affect it.

    Hmmm, a question occurs : were there any aviation bans associated with the Grimsvotn eruption of 1996/8? No reports that I know of.
    What about the Grimsvotn eruption of 2004? Ah, 59 flights cancelled from Schipol and numerous more diverted. That's an unprecedented new meaning of "unprecedented".
    I'm slightly surprised to read that report myself - I've known that Grimsvotn has been erupting irregularly for over a decade (it's on the to-do list if I can persuade the wife to come on holiday to Iceland ; but don't tell her!) ; I hadn't heard about the flight impacts until just now. But then, I'm a rock-doctor, not a joy-stick jockey. I had been feeling slightly contrite that my subject (Earth) and my colleagues (rock-doctors) may possibly have not given sufficient reasonable warning to the aviation industry (apart from throwing planes out of the sky, burying military and civilian airbases, etc, etc), but it look as if the Earth has been throwing lumps of rock at planes over the north Atlantic for years. That puts the ball squarely back in the aviation industry's court over why they hadn't foreseen this eventuality.

    Oh well. News item : Humans get given plenty of warning of natural events, and humans don't pay the blindest bit of attention.

    they're going to desalinate the Red Sea to provide water to communities instead of using the Jordan River.

    Almost certainly that's not what they're going to do.

    Leaving aside the political benefits of beggaring your neighbour by taking all the water you can from the river that forms your mutual border, the basic geography is against desalinating Red Sea water and shipping it to the north of Israel and the Palestinian West Bank : the Red Sea only contacts the southernmost extremity of Israel. If the Israelis want to supply northern Israel with desalinated seawater, it'd be considerably cheaper to build the desalination plant somewhere on the Mediterranean coast - around Haifa or a bit south of there. Pipelines aren't cheap, and are vulnerable, so you minimise the length of them. (Obviously this'd leave the population of the Palestinian state up shit creek ; but that's policy anyway.)
    If some desperate fool wants to farm the Negev, then build a desalination plant on the Red Sea coast, or possibly a Red-Dead canal (it is downhill, mostly) and your desalination plant at the Dead end of that ; surplus water goes into the Dead Sea, and up into the atmosphere.

    "Forms of life we've never seen may well be atermal." means "Forms of life we've never seen may well not depend on temperature"

    That's still a pretty ... odd ... concept.

    Of the one biochemistry that we're familar with ("CHON"-based, Carbon, Hydrogen, Oxygen, Nitrogen ; nucleic acids as polymeric information carriers and amino acid polymeric chains as catalytic molecules), all forms require the presence of liquid water for active life (growth, reproduction) ; unsurprisingly then these life forms are restricted to a pretty narrow range of temperatures for activity - between about 260 and 400 Kelvin. While their chemistry requires the presence of liquid water, I don't see them ever getting to much lower temperatures because you can't remain liquid at much lower temperatures with anything even vaguely resembling pure water (there's a minor caveat for really strong ammoniacal solutions - that may take the bottom of the temperature range down by ten, or at a real stretch twenty Kelvin). Going to higher temperatures and the thermal instability of the molecules involved becomes unsupportable well below the temperature/ pressure regime at which "liquid water" ceases to become a valid concept and you're using critical or supercritical solvents. Let's be generous and say that ultimately you can get "our" system up to 450 K, given a high enough pressure (I've never heard of evidence of any life-like activity that high, even in "black smokers" and the like ; but I'm a geologist, not a biologist with a thing for hyperthermophilic bugs).
    250 to 450 Kelvin is not a particularly wide range of temperatures ; it's not even an octave. Significant areas of our planet go to lower (to about 200 K) and higher (approaching 1900 K) temperatures. In our planetary system, lower temperatures are very common on planetary surfaces and higher temperatures are common in planetary interiors ; but both of these broad areas are likely to be inaccessible to "our" biochemistry.

    Theoretically, you could look at biochemistries with different solvents. Ammonia is credible ; carbon dioxide would be difficult because of it's narrow range of temperatures and pressures where it's a stable liquid ; methane/ ethane is interesting. But each and any such system that could be developed is going to be moderately constrained by existing in the temperature (and pressure) regime where it's main solvent is liquid.
    In the Star Trek universe it might be credible to have organisms that can survive having their main solvent boiling within their cells ; but I don't see how that could happen in real life.

    Could a biochemistry be based on something other than "CHON"?
    It would be unwise to say that it's impossible, but they are the most abundant of what the astronomers call "metals" (anything that is not hydrogen or helium, and one of "CHON" is hydrogen!) and they hold that position for very simple, powerful reasons of nuclear physics. So if there are a million different biochemistries in our galaxy, it's a fair bet that 999,000 of them are CHON-based (the other thousand-odd I leave to allow for more sulphuric biochemistries than ours). Silicon does have some interesting polymeric chemistry (nesosilicates, nektosilicates and the like ; fascinating and important materials that I do study intently for my employment), but it's nowhere near as complex as the chemistry based on carbon.

    I really fail to see what you could mean by an "athermal" form of life. Outside the likes of Star Trek.
