2009/2/15-18 [Science/GlobalWarming, Computer/HW/Drives, Science/Electric] UID:52576 Activity:nil | 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

2006/10/9-10 [Science/Electric, Science/GlobalWarming] UID:44738 Activity:high | 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

2006/6/15-17 [Science/Electric] UID:43400 Activity:nil | 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.

2006/5/12-17 [Science/Electric, Science/GlobalWarming] UID:43031 Activity:nil | 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,

2006/3/6-8 [Science/Electric] UID:42116 Activity:kinda low | 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

2006/3/5-8 [Science/Electric] UID:42101 Activity:low | 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

2006/3/1 [Science/Electric] UID:42041 Activity:moderate | 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

2006/2/18-23 [Science/GlobalWarming] UID:41917 Activity:nil | 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?

computers (GAY TURING), jets.
What did the Iraq war bring us?
