2/15    How many watts does a typical desktop (not counting monitor)
        use when it is completely idling (top shows at most 1-2% CPU),
        assuming normal SATA HD, video card, 2-4G RAM?
        \_ Google did a published study where they determined that the
           largest consumer of energy in a computer is the power supply
           itself. Figure that if you have a 400W power supply you are

3/3     Photos of weather stations...badly placed weather stations.

        \_ Oh, so global warming is just caused by concrete?  I'm so relieved!
           All those dumb scientists ought to read angry guy's blog!

10/9    So this whole plugin hybrid campaign thing...  Wouldn't that completely
        fuck the CA power grid if even a few % of drivers bought those?
        \_ the real issue is not rather CA power grid can handel it.
           I was told that if we modify it to make it plugin, it will
           drastically reduce the life span of the rechargable battery of those
           Prius, thus make the car a lot more prohibitive than it would

6/14    I'm in S Cal and LA Dep of Water and Power charges me approximately
        $1.00 per 10KWH (KWH is 1000 watt hours). I don't watch TV at all,
        but my computer's on all the time. Suppose I do get a TV,
        and suppose I watch TV 4 hours a day and the TV is rated at
        300W, how much does that contribute to the cost?   -cheap ass
        \_ Look for a product called "Kill A Watt", it's about $29.

5/11    I bought a few expensive LED lightbulbs. Comments: when they say
        an LED is equivalent to X watts incandescent bulb, it's marketing
        bullshit. In reality, it's more like X/2 or X/3. LED bulbs may
        save you a lot of energy, but they're simply not that bright.
        Secondly, they look very very unnatural. With incandescent bulbs,
        you get various frequencies and things look natural. With LEDs,

3/6     So where can I get a 120V->220V adapter? I'm thinking about buying an
        induction stove which is rated for 3000W at 220V 60Hz.
        \_ in this case, i would strongly approach this with a different route
           than getting a transformer.  3000 watts is too serious of an
           appliance for a 3rd-party transformer.  Most of new household has
           one or two 220volts sockets somewhere mostly for air conditioning

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

3/1     Say I have a circuit breaker that says 20A. How many watts can I load
        on it before it pops? I'm asking because every time I have a space
        heater (1500W) and hair dryer (1850W) on, the circuit breaker pops.
        \_ P = VI  where P is power in watts, V is voltage in volts, I is current
           in amps (A).  Wall socket voltage is a max of 120V in the USA and is
           220V-240V in some places elsewhere.  Can you figure it out now or do

2/18    Back in 2000 I bought a few 23W energy efficient bulbs that
        output 100W, and a few 16W bulbs that output 60W. The
        (output/energy used) ratio was about 4. Today I bought a
        few more bulbs from Walmart...  7W bulbs that output 40W,
        which has the (output/energy used) ratio of over 5.
        Are new bulbs getting more and more efficient?
