  1. You have to cook it under your scaled replica Cheops pyramid at the one
    third height level, while wearing your pyramidal foil hat with Salvador
    Dali on the widescreen in the living room.

    Don't forget all of the Mayan culture wall hangings.

    If all else fails, read the instruction book. I didn't see anything in the
    cookbook about pots/pans, but according to Webster's Dictionary a kettle is
    a bowl shaped metal utensil. I take that to mean it has a rounded bottom,
    like what one would use for making witches brew. Probably not useful on an
    electric stove.

  3. Describe the mechanism by which it heats.

    Hint:

    The word for today is hysteresis.
     


  4. See? They were aHEAD of their time! ;-)

    You're not familiar with these ?

    There is a crucial distinction between the kettle, in which the water is
    boiled, and the teapot, in which the tea is brewed (infused). If you've
    been putting the tea leaves (or even bags) in the kettle, it's no wonder
    the Americans prefer coffee.

    There are other kinds of kettle, with neither side- handle nor spout,
    but that's a different kettle of fish.

    A 'kettle' is of course historically simply a word for a container.

    It seems to me that Tam is confusing the British kettle meaning electric or
    cordless kettle with the American 'tea kettle' which is not a term used in the
    UK.

  10. Out of the frying pan, and into the kettle...
     
  11. Go for a simple dictionary:-

    Collins GEM English Dictionary
    kettle n. container with a spout and handle used for boiling water. ˜a
    fine kettle of fish an awkward situation.

    By that kettle has also an older meaning in the UK. There's also a paint
    kettle - an open pan with wire handle used by decorators.
     
  12. Nor can you with a frying pan. Have you a fetish for only using one type
    of cooking utensil?
    Continuously boiling water for cooking needs?
    If you are boiling water 'continuously while cooking' you know nothing
    about conserving energy. Or cooking, come to that.
    Of course you could just be a troll.

    Hey, you never met my dad. He used to boil eggs in the electric kettle.
    I think you can place your stuff in there, it's getting it out again
    that's the problem. But if you've forgotten to let the Beaujolais settle
    to room temperature, DON'T try putting it in the electric kettle for a
    quick boost.
    All those civil servants sitting around drinking endless cups of tea.
    But if the cups are endless, how do they get the tea out?
    Some people are so easily satisfied.
     
  14. Thanks for confirming you don't know the difference between energy and
    power. It's pretty common with cretins.

    Kettle? We just cut a 55-gallon drum in half.

  16. With their endless red tape, of course!

    For what it's worth, the dictionary defines a cauldron as a large kettle. So
    to me, a kettle looks something like a cauldron, but not as big. I don't
    know anybody who owns an electric tea brewer, though I do own 3 electric
    coffee pots. The UK folks might be ripe for a samovar.

  18. So, how many PCBs do you think you have introduced into your body over
    the years with all the various and sundry exposure events we Americans
    have the opportunity to endure?

    Some useful information:
    1 cup is about 236.6 ml.
    It take 1 cal to raise 1 ml of water by 1 degree.
    A watt is about 0.239 cal/second.

    Let us assume the cup of water starts at 25 C and you want to raise it to
    100 C, that is 75 degrees that we want to heat the water.

    So, it will require (236.6 ml x 75 deg x 1 cal/(deg x ml)) = 17744.25 cal
    to raise a cup of water 75 deg C.

    You can deliver those cals at any rate you like[see notes below]. A 1 kw
    heater will deliver 239 cal per second. A 2 kw heater will deliver at
    twice that rate.

    74.3 seconds to heat a cup with a 1 kw heater.
    37.1 seconds to heat a cup with a 2 kw heater.
    [notes: ignoring losses in wiring, assuming efficient heat transfer from
    heater to water, assuming no loss of heat from cup+heater combination]

    If you want to factor in any of those, please state your assumptions [such
    as thermal transfer resistance between heater and water, between container
    and air. Those act much like series resistors as far as the heat is
    concerned. You can model temperature difference as voltage drop and heat
    transfer as current if you like. Any good engineering heat transfer text
    will show you exactly how to do this{but in this case, it won't really
    matter all that much}].

    You're fixating over a combined device for heating the water and brewing the
    tea.
