4/24    Is a coffeemaker more/less efficient at boiling water than a
        microwave? What about versus boiling water in a pot on an electric
        range? Are they all about the same?
        \_ Most efficient is a coffeemaker because if has a heating coil
           immersed in water.  Stoves and microwaves are both pretty
           efficient.  The stove wastes heat due to it escaping around the side
           of the kettle.  The microwave wastes energy because the magnetron is
           not 100% efficient an converting electricity into microwaves.
           Least efficient though is when you brew using a coffeemaker and
           then leave the coffee warmer on for hours.  You should also
           consider the inefficienty of burning fossil fuels to generate
           electricity.  Best would probably be making coffee with a kettle on
           a gas burner slightly smaller than the kettle.
           \_ I wonder how much fossil fuels get used just to grow, harvest
              and transport the coffee beans to your home.  I'm guessing
              that if you calculated that, the added fuel use of heating
              the water would be insignificant.
              \_ I don't want to make coffee. I want to boil water. --op
                 \_ Uh, coffeemakers don't boil the water.  And if yours does,
                    something's wrong.
                    \_ Uh, yes they do. Just don't put any coffee in it and
                       you get a potful of hot water. It may not be boiling
                       hot, but hot enough.
                       \_ Uh, no they don't.  'Boiling hot' is not boiling.
                          If your coffee maker really boiled water it would
                          make gross bitter coffee.
                          \_ You're just a nitpicking git.
                             \_ If you're going to be correcting someone, be
                                correct yourself. (re: 'Uh, yes they do')
                                \_ Coffeemakers do make hot water, you
                                \_ Coffeemakers do make boiling water, you
                                   dipshit. It's a nitpicking git to say
                                   that they don't because the water only
                                   reaches 210 degrees (or whatever).
                                   reaches 200 or 205 degrees.
                                   \_ So, you're saying it's boiling
                                      water, just at a slightly hight
                                      altitude?
                                      \_ I'm saying you'll think it's
                                         boiling when I dump a pot of it over
                                         your head.
                                         \_ But will it give you 3rd degree
                                            burns like Mc Donalds coffee?
                                            \_ It'll certainly send you to the
                                               hospital after I jam the empty
                                               pot up your ass.

10/5    Make sure to watch The Crumbling of America on History today! America's
        infrastructure is collapsing. Tens of thousands of bridges are
        structurally deficient or functionally obsolete. A third of the
        nation's highways are in poor or mediocre shape. Massively leaking
        water and sewage systems are creating health hazards and
        contaminating rivers and streams.
