Thus adding instantly billions of tons of CO2 to the EU totals. They will be forced to buy their power from outside the EU, so it won't effect the totals (for the EU). So that is ok then.... That's like Britain's manufacturers taking production facilities from the UK and making their goods in the far east instead. The result is something like a 20% drop in CO2 emissions, and NuLabour are patting themselves on the back for this "achievement". But the real cost of exporting manufacturing production is that the goods are made in factories that are powered by China's grossly polluting coal fired power stations and shipped to the UK with ships that belch CO2 along with some really toxic nasties. Apparently, the overall change in Britain's CO2 emissions if this Chinese malarkey is taken into account is an *increase* of 28%. But that's OK, because emissions from Chinese factories and the ships do not contribute to the UK's Kyoto target. |

No it doesn't, in fact osr isn't too bad to get a liquid fuel, it beats having 1/5 of the arable area under cultivation for fodder for horses. In terms of just thermal efficiency wood harvesting is pretty good but there's a lot more utility in a litre of diesel than 6kg of freshly harvested wood. And you would need about 50 times the area currently under agriculture to get near UK demand. Probably, there's about 18 million ha of farm land and about 25% of this is arable we might be just about self sufficient for food if we maximise crops for direct human consumption AND continue to use fossil fuels and fossil derived fertiliser.

I suppose re-using cooking oils is deserving of a better press as most of the energy investment has already been made. And you would need about 50 times the area currently under agriculture to get near UK demand. Also oil seed rape is normally only grown once in a 5 course crop rotation: usually as a precursor to Wheat. Permanent cropping would require major developments in disease and pest control. I understand the Americans are diverting some of their Maize to ethanol production, much to the consternation of the Mexican food industry:-) regards -- Tim Lamb |

It suddenly struck me that we (mankind) have never MADE anything. What we humans have done and still do is to change/alter things to our use. No matter whether it is some fairly recently (10 to 100 years) grown wood turned into charcoal or furniture or 10 million year old fossils which became oil, coal or gas. Or plastic or .............. parts for motor cars etc. Just about anything we humans do to 'produce' energy is to change something originally manufactured from sunlight! If you go back one step further, there is only one source of energy - fission or fusion of elements generated by the big bang. The only way to use these is in nuclear reactors.

So much of the heavier elements were formed in fusion reactions before the earth formed? Elements further up the periodic table than iron are all formed in supernovas. Elements from and including iron downwards are formed in ordinary stars. If you fuse elements lower down than iron, you get energy *out*. To fuse elements above iron, you have to put energy *in*. An ordinary star will firstly fuse hydrogen to helium - the Sun does that. Every second about 650 Mtons of H are fused to form 645 Mtons of Helium. So the Sun gets lighter by about 5Mtons/sec, which is converted into energy according to E=mc2. Even after 4.5Byears of this, the Sun has only converted a few % of its mass to He. In some Byears time, the Sun will run out of H, and have to start "burning" Helium to heavier elements, progressively up to iron. It is, however, too small to go supernova. If you're interested in more details, get hold of "Stardust" by John Gribbin - very readable. One reason for the core to be iron is that decaying elements tend toward iron as the most stable state I think. No. Firstly, elements higher up the table than iron are quite rare, comparatively. Certainly much more than 99% of the Earth's iron core was iron when the earth formed. Second, the "bottleneck" at iron is a feature of the strong nuclear force. Radioactive decay is mediated by the weak nuclear force, and as each radioactive isotope decays, at a rate given by its half-life, it gives rise to "daughter" isotopes which themselves may decay - or may not, if the isotope reached is stable. Thus, Uranium decays to Lead which is stable. Lead (atomic number 82) is much higher up the periodic table than iron (26). -- Tim "That excessive bail ought not to be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted" Bill of Rights 1689 |

And the whole of GB is about 60 million acres, so we all get approx one each. IF it were all good agricultural land, its just about enough to eke out an existence..one acre pre person. At the sort of paleolithic level Greenpeace would like us to revert to. It isn't though, and to survive loss of 'artificial' energy implies sort of 2-5M population levels. Which would be ideal, If I were one of the 2-5M.And all those fat gits at Tescos were not. |

Parts of the earth were some sort of self moderating chain reaction but I thought that was no longer self sustaining and it's just the decomposition of unstable elements formed from then that keeps the middle warm now? Its a moot point as to when natural decay becomes a reactor. Natural decay will occur however concentrated or dilute the isotope in question is. You get a reactor if you concentrate the material. With uranium you need about 3% or more of U235 (up from the natural 0.7% level). When a U235 atom fissions, out come some fast neutrons (and heat energy). If you slow these down ("moderate" them), these neutrons can themselves act like bullets which fission more U235 atoms. In a reactor, you need to keep the number of slow neutrons produced per U235 atom-fission at around 1.0. A bit above, and the reactor produces more heat. A bit below and you cool it off. This is done by inserting control rods which absorb the neutrons. If the ratio gets too much above 1.0, then you are in trouble. Obviously with a bomb you want it as much above 1.0 as poss. -- Tim "That excessive bail ought not to be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted" Bill of Rights 1689 |

You may also be thinking of the natural uranium reactor at Oklo, in Gabon, about 2 billion years ago. That's it. So much of the heavier elements were formed in fusion reactions before the earth formed? One reason for the core to be iron is that decaying elements tend toward iron as the most stable state I think. Correct to my knowledge. No, see my post of yesterday. -- Tim "That excessive bail ought not to be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted" Bill of Rights 1689 |

That's like Britain's manufacturers taking production facilities from the UK and making their goods in the far east instead. *The result is something like a 20% drop in CO2 emissions, and NuLabour are patting themselves on the back for this "achievement". Or how the unified Germay achieved it's targets by simply shutting down the old industrial plants in the East. It's all greenwash. MBQ |

And for the first time ever I agree with the Green Party. Why? This was government and regulation ********. Npower just did what saved them several million quid. It's the same sort of official ******** that's forcing us to have bio-fuel, even though that will be grown at the expense of food and in some cases of the rain-forest. I agree. It's totally stupid but NPower didn't make the rules and they had shareholders to think about. It's the short sighted idiots who drew up the scheme who we should be complaining about.
