Comment The issue is simple (Score 5, Insightful) 343

Power lines were never meant to carry RF energy. When they are, they radiate. Cable TV doesn't radiate. It doesn't radiate because it uses a proper transmission medium (Coax). If the power line folks want to distribute DATA, they should string the poles with fiber optic. Better yet, we the people should string it, and sell access to the content providers.. ala municipal fiber networks. They can work folks!

Comment Where would you go? (Score 1) 629

Easy, Fry's Electronics. They are the better Radio Shack. They are what Radio Shack should have grown to. You're lucky if your local RadShack even has solder these days. A 220uf/25V cap or a 2N2222?... NEVER! They lost my electronic hobbyist business years ago. I will never step into their stores ever again... unless I want skins for my Nokia. lame lame lame.. I hope they do rebrand! That's the sign of a sinking ship. Let it sink.

Comment Re:library of congress (Score 1) 495

According to local folklore at the time when I attended to RIT in Rochester, NY., the builders of the library didn't take into account the weight of the books when designing the foundation which is why the building is sinking into the swamp it was built on.

We could expound on your idea and look at the weight of an electron as it clocks through a CPU and find out what a bit really weighs(?)

Electrical current is the amount of electrons passed over time (coulombs per second). If we assume a pull-up resistor is 10KOhms and the data is clocking at 500 megahertz running on a 3.3v supply, we'd get:
3.3 V / 10,000 ohms = 330 micro coulombs per second (ampere)
330 uA / 500,000,000 = 660e-15 coulombs per bit
1 coulomb = 6.241506e18 electrons

Therefore, in this example, electrons per bit is:
660e-15 C/b * 6.022e23 electrons per Coulomb = 397.452e9 electrons per bit
one electron weighs 9.11e-31 kg, therefore:
397.452e9 electrons per bit * 9.11e-31 kg * 8 bits per byte = 2.896630176e-18 kg per byte
1.0E+15 (peta) * 2.896630176e-18 kg per byte = 2.89 grams

One petabyte weighs 2.89 grams worth of electrons assuming all values are ones. The weight of the library is the important part in this case.

Comment Re:Just outlaw the use of copper.. (Score 1) 161

Yeah, that's a good angle. We could even go further and mention the amount of money the telcos could recoup from recycling the copper lines they remove from the poles. Most predictions say around 33 years until there is no minable copper left! Silica is the raw material for fiber cables, and we got plenty of sand in the world.

So therefore, replacing those big fat overhead multi pair copper lines with a small optical fiber is good for the environment.
