3/5     If an appliance is 220V, can I get an adapter or something for it
        because I have 120V? Thanks.
        \_ A transformer, yes.
        \_ I had a similar problem.  You need to be very careful about
           the actual wattage of your appliance.  A transformer that withstands
           large wattage tend to be very very big (size of couple bricks and
           weights accordinly).  *FURTHER*  You can *NOT* just look at the
           weights accordinly).  *FURTHER*  You look can NOT just look at the
           peak wattage, let say, 200 watts, and shop for a transformer that
           can handles just 200 watts.  There is some sort of multiple (of
           that 200 watts) is involved.   You need to bug other people on
           MOTD who actually passed Physics 7B to give you the answer.

         \_ Your house normally has a 220-240V mains that is seperated into
            two 110-120V circuits.  You can combine these to provide a 220V
            outlet.  An electrician can put one of these outlets in for you.
        \_ Your house has 240V mains which is basicly split in two to make your\
           two 120V circuits.  You can have an electrician set up a 240V outlet,\
           which will be easier to transform down (if necessary) to 220.
            \_ While this is true, whether this is a good idea or not
               depends on the appliance.  In this case it's probably some
               kind of euro import or something, which would mean it's
               probably a bad idea.
               \_ Sure, if there is a motor, the 60Hz will cause some problems
                  for something wound for 50Hz.  Many appliances have no
                  problems though.  So really, what the hell is this appliance?
        \_ If it's something portable, like a router, etc, you can
           probably get by with a transformer or voltage converter.
           However, if we are talking about electric dryer, then you
           BETTER get an electrican and get a proper 220v outlet.

12/15   I'm planning on traveling to Europe and I was wondering if there's
        any reason I shouldn't be able to use a US power tap/strip (no surge
        suppression) with just a plug adaptor (i.e., no voltage conversion).
        This would be for use with electronics that accept 100V-240V. While
        the power strip is intended for use at 120V, it's just wires, right?
        (Also, this power strip has no power LED or similar.) If anything,

11/11   Watch the History Channel today! It's got Oppenheimer and the atomic
        bomb history. Did you know at one time 10% of the entire electricity
        in the U.S. was used to refine U235 and weapon grade plutonium?
        Holy jesus! I wonder how much energy is used to get plutonium fuel
        that generates today's nuclear powered electric plant
        \_ it talks about the 2 different methods for getting U235. So

5/18    Does the new federal vehicle fuel-efficiency requirement specify how
        efficiencies of plug-in hybrids will be calculated?  Some plug-in
        hybrids claims to have ridiculously high efficiency like 100mpg because
        they're not counting the energy input from the electric grid.  That's
        not a good indiction of their actual energy efficiency.

7/16    China burned 1.9 billion metric tons of coal in 2004. By 2020, predicts
        the China Coal Industry Development Research Center, it will burn 2.9
        billion tons a year. That increment alone will send as much carbon
        dioxide into the atmosphere as 3 billion Ford Expeditions, each driven
        15,000 miles a year. This puts into sobering perspective the meager
        efforts of the U.S. to stave off global warming by improving gas
