Although voltage and currents may be different, the wattage "should" be the same! I wonder how much less efficient 110V equipment is with them drawing a higher current and losses being relative to the square of the current?
Science in action!! How!
I dont think this does jack **** for electricity usage.
But its worth a test. I am going to get one of those watt-meter things and measure how much my Dell 2407 24" screen uses with standard google and blackle.
It does for CRT users It has been demonstrated by the designers who do use CRT. CRT is still being used primarily by those who can't afford to upgrade to more efficient tech. I see them all over the place here.
