The major losses are not in transmission, they are in converting the energy stored in the coal, gas,... to electric energy. For a coal plant, this process is about 40% efficient.
You should also consider the efficiency of the power plant when calculating the difference between NG and electric heat. The efficiency of a typical coal fired electric plant (most common in USA) is about 40%. So for every 1W of energy it produces it uses about 2.5W. Therefore, 1W of heat from your electric light bulb will require 2.5W of energy (Neglecting any distribution losses). 1W of heat from NG (assuming 90% efficient furnace and 10% distribution overhead) will use about 1.25W of energy.
This is why resistive heating is not a great option for heating.
If you do the same calculation for a heat pump running at 250% efficiency: 1W output => (1/250%)/40% = 1W input.
I suppose if the kid got into my salon's database he/she would learn my name, phone number, address, and that I like my hair cut with a number 2 guard and my sideburns trimmed.
I could be concerned if 75% of this information was not in the White Pages.
All over the US there are private roads and people voluntarily pay tolls to travel them because, brace yourself again, they provide a much more pleasant commute. They deal with traffic congestion immediately, they undertake repairs and maintenance quickly and effectively, without bloated government bureaucracy making repairs and improvements take years and cost tax payers millions of dollars and they do it with their own money.
Toll roads work pretty well for highways, but they would be a nightmare for surface streets. If corporation XYZ controls the street connecting your driveway to the outside world, you are pretty much screwed if they decide jack the toll rate up. What would your solution be? Would you have multiple toll roads connecting to your house so you could decide which way would be the cheapest way to travel to work? Expanding or building new roads would be more expensive and slower then it is now as corporations would not have emanate domain to fall back on if someone won't sell.
99% of data that is worth accessing is accessed enough to ensure it is in a readable format. As far as the other 1%, it will give our children of the future something to do. Sounds like another stupid excuse for everything to be open and free. Some things are better proprietary and expensive.
Thank you for linking to that insightful video. As an electrical engineer, I feel it is one of the best explanations of a cathode ray tube that I have seen in some time.
What they should do is get the processors to run at 100 degrees C. Then they could use the heatsinks to boil water, the steam to turn a turbine and the turbine to generate electricity. It would be somewhat like the turbocharger for your car.

Steel wool will scratch glass. If you don't believe me try it. Heck, if I was you I would buy a macbook, try it, and post the results on youtube. Please forward me the link.
Go ahead and buy a glossy screen. On the way home stop by the grocery store and pick up some steel wool. Rub the screen with the steel wool and Voila!! A beautiful matte screen.
Wouldn't the sheet be the only thing not following the classical law of gravity? Due to the fact that the equation specifically states the force exerted varies with inversely with the square of the distance of the 2 objects. Sheet and Earth in this example.
I hope that was sarcasm, because really who hasn't heard of 16systems.com and their (not so) great challenge. The publicity from winning this is next to nothing.
I don't get this argument. It is not like Myspace or any other service your are griping about is some government program that you are entitled to. They are a business trying to make money. Increasing the relevance of their ads helps increase their revenue. Technologies such as ad-blockers are becoming main-stream and will tend to decrease their revenue. Measures like targeted marketing may be needed to maintain their current profitability.
IMHO, you are lucky these services give you an option to opt-out. I guess it must make some sort of business sense for them.
Something seems inherently wrong in using 2 separate tests to determine if a poster is human. If a bot is able to fool one test but not the other, why wouldn't you throw away the test it can fool and only have 1 test. If some bots can fool the first test while others can fool the second, then it doesn't take much to combine them to get around the entire system.
Sense the research was sponsored by TI, I am sure this technology will find its way into all sorts of embedded devices. Think everything from 32-bit uCs to Opamps. If it really does increase power efficency 10 fold, it wouldn't supprise me to see AMD and/or Intel license the technology from them for high speed uPs.

From the summary:
He refutes reported claims that it's just a kidney shaped mold, as reported by some.
From the linked story:
Wake Forest has since clarified media inaccuracies in a press release, stating Dr. Atla printed "a kidney-shaped mold", not a functioning kidney.
Did he print an actual kidney or not. I am guessing not.

I second that.
Oh there you are Chuck. I've been looking for you. So...where are you living now days?

Actually what I meant to say was you would not be able to receive them from your friends either.
Call the phone company. They will block them, but it involves shutting off your entire SMS service so your friends can't send them either.
Sorry to be offtopic, but I love you sig...It is a sad day, isn't it.

With RoHS firmly in place, there is no lead in the solder of almost any circuit board built post 2006.
