That all makes good sense, except the last bit. Apart from that, ethanol from cellulose is something of a holy grail, lacking really effective/efficient technology, but all signs are that that's changing, or on the point of changing. There are some good resources here: http://journeytoforever.org/ethanol_link.html#cellulose Re the last bit, I think the Arabs are much less to blame (?) than past and present US foreign policy along with (very much! - in concert with) the machinations of the Seven Sisters, or however many sisters there are these days. Demonising the Arabs is popular but not very accurate and a distraction from the real issues - to the benefit of the real culprits, if that's the right word. Generally they're culprits all right, but the idea that the US is being held to ransom over foreign oil supplies is a gross oversimplification, if not just plain wrong. There's a lot more to it than that, eh? During the oil embargo of the early 70s the Seven Sisters worked hard to promote that myth, with much success, but subsequent analysis showed who the real beneficiaries were: the Seven Sisters, not the Arabs, who, in some ways, were victims like everyone else. Anthony Sampson's excellent book The Seven Sisters has much about this, but I think good supportive info is not hard to find. This demonising is damaging to all concerned, demonised and demonisers, as well as to innocent bystanders, and it's also downright dangerous. regards Keith ------------------------ Yahoo!
