    Didn't I read that it took more energy to make biodiesel
    than it contained?

    What, you mean conservation of energy really is true?
    Entropy is actually increasing?

    Gosh, and tehre I was thinking the physicists were just
    having a laugh.

    Quite possibly.

    But they were bullshitting propagandists who said so.

    The propagandists on my side say there's an 84% energy yield
    on it from their studies. Which is not dissimilar to the 84%
    energy yield from petrodiesel. Just that the biodiesel does
    it inna carbon-neutral stylee, and the petrodiesel doesn't.
    See www.biodiesel.org for details: I may be a few per cent
    out with my figures but they're in the right ballpark.

    Possibly, but if you're into the home brewed version using
    recycled frying oil then at least you can recoup some of
    those energy losses by using it to make some nice chips or
    a deep fried Mars bar (oops, Scottish upbringing coming
    out there).

    I have given serious consideration to making my own fuel
    from recycled frying oil but the Aussie govt. has just
    announced plans to tax it like other fuel (making the whole
    exercise rather pointless financially) and the idea of
    making it in the garage might not appeal to the owner of our
    rented house :-(

    But you're right, C&E do not appear to require a warrant,
    or even reasonable suspicion.

    When I ran my own business (IT contracting) and knew many
    other people in the same position, the one concern we had
    was stuffing up a VAT return. Inland Revenue just send
    you nasty letters for a while before they do anything,
    C&E can knock your front door down just because they feel
    like it (or at least that's the level of respect they
    seemed to command).

    Quite plausible.

    Are you sure it's not 85% of energy yield, with 88% of
    serious energy released?

    n its natural state, the land devoted to growing biodiesel
    will be covered in vegetation, and absorbing CO2. When
    growing for man to burn, the same is true. Except that
    burning it then re-releases the CO2. So you've just
    neutralised land that *should* be making a positive
    contribution - which is not so very different overall to
    burning fossils but leaving todays plants to grow instead.

    It may be complete bollocks, but is the cutting down of the
    vegetation not compensated for by the increased CO2
    absorbtion of younger, faster growing plants as opposed to
    older, slower growing ones? I seem to remember some company
    (Andrex?) using that in some advertising blurb about being a
    green company and replanting trees some years back (which
    makes me think it is more likely than not to be nonsense).

    The problem for us in the UK is that home distilling is
    illegal and anyone posting here saying they did it
    would probably have a swift visit from Customs and
    Excise who seem to have more right to enter your house
    than the police.

    I've never looked into this but my trusty A level chemistry
    teacher (Hello Mr. Jones) told us that distilling by boiling
    off the ethanol was illegal, but distilling by freezing off
    the water was not (or maybe it was freezing off the
    ethanol). Whichever way round it is, he reckoned that
    distilling by lowering the temperature was legal.

    I've never needed to check the legality out for myself.

    Methanol isn't that much of an issue in freeze distillation.
    Distillation doesn't create methanol but it does concentrate
    it. If a bottle of wine contains 2mg methanol and you
    condense the bottle down to 1 glass, you will still only be
    drinking the same amount of methanol, so the headache will
    be the same. The only time to worry about it is when you're
    using a pot still or reflux column as the first runnings are
    comparatively very high in methanol.

    Have a look at homedistiller.orgmethanol.htm

    I don't quite understand how land can make a positive
    contribution to being a carbon sink except for turning the
    soil into a carbon sink, and presumably that runs the risk
    of liberating quite a lot of methane from the rotting
    vegetation as well, which may be a gain in terms of CO2
    levels, but hardly in terms of greenhouse gases.

    Presumably soil also has an output role to play in the
    carbon cycle as not all the world's carbon has dissappeared
    into soil and coal (although of course a fair proportion did
    upon the invention of the tree, but since then, AIUI CO2
    levels haven't changed much)

    Creative accounting is all about conveniently hiding
    things like that.

    But it's fairly safe to assume that cultivated land will
    also be producing products that are turned into carbon
    dioxide somehow, except for trees that eventually end up
    as landfill.
