    Spinning a generator is daft but it happens, when it does, does its efficiency drop to zero or is it infinitely inefficient?

    In electrical generation terms. Can't think what made you think of this Tony :wink:

    hmm. apa is struggling to comprehend the difference between:

    >does its efficiency drop to zero
    >or is it infinitely inefficient

    seems to be semantics, although I do understand why generators sometimes spin and not produce energy. It's because they "might need to do so in a hurry", so I guess you need to factor the efficiency / inefficiency into the whole power generation mix, rather than treating it in isolation

    What happens to the fuel meter in your car when you stop at lights? Mine switches from the "per gallon" to "per hour" consumption rate.

    Wind farms consume electricity when idle. Does that make the efficiency negative :-)

    Ah, the secret here is to get your head around the fact that Tony is Perversity Personified, which is why the threads started by him end up going on, and on, and on, and on...!

    I suspect he is a Zen Master. Not so much with a benign, enigmatic smile on his face, but an evil grin. :tooth:

    Recent Gov energy policy announcements appear to create a situation where operators will be paid for plant to be idle , if spinning standby then this will be negative both for energy and emissions consequences.
    Large subsidies will be given for each MWh produced by renewables which provides incentive for maximum running/output but creates questions surrounding which plants used to provide this need and level of subsidy for those not required. What will be priorities in use decisions, minimise imported resources, minimise air quality impact or to use process that maximises profit?

    guess which of the drivers will win

    Tony- sadly not the one that results from joined up thinking or due diligence.
    For something completely different
    http://www.guardian.co.uk/money/2011/jul/20/which-money-saving-eco-products-avoid
    Anything to add to list?
    Sorry if should be on another thread but "products" appears closed.
