The patent system exists as it does because established companies wish to inhibit innovation that could cause them economic harm and they have the pockets to buy legislators to do their bidding.
I was speaking of long distance transmission, where very large conductors are used and skin effect does play a significant role in limiting the max effective size of an individual conductor and in the composition of the conductor as many long distance transmission wires use a steel core with an aluminum sheath because the skin effect causes most of the current to ride the edges.
For less industrial-level conductors, yes, the skin effect is negligible at 50-60Hz.
Very high voltage was the answer to how to transport electricity long distances. AC was the answer to how to convert that high voltage to safer/useful low voltages cheaply. Very high voltage DC can lose less power over distance than AC. On smaller/cheaper wires too due to the AC skin effect.
In particular, about 80-90% of the cover price of a book has nothing to do with the paper and ink object you buy in a shop; indeed, using current production standards, ebook production requires nearly as much work as paper book production. (Paper and ink are dirt cheap; proofreaders and marketing teams aren't.)
Didn't the publishing industry nearly double paperback prices just a few years ago citing increases in paper costs?
When people think of generating energy from hydrogen through a chemical reaction - usually resulting in H2O, and THEN say no problem getting the hydrogen because we can just split water with the electricity generated there is a problem because BOTH are chemical reactions - generally the same one - and entropy states that you will never get the energy out of it that you put into it.
However, this is not supposed to be a chemical reaction, but a nuclear reaction. Transmutation of elements can produce vastly more energy than you would get through the chemical reaction. So just a small fraction of the energy produced by fusing the hydrogen liberated from water will be plenty to split water chemically.
Electricity transmission over distance is much more efficient as a high voltage/low current AC than DC current, especially since you can't use transformers on DC.
Not entirely true. High voltage DC (HVDC) is more efficient for long distance transmission. It's more that AC is most economical for medium distance with lots of tap-in points.

I'd mod you up if I currently had mod points. The summary is garbage by not mentioning that it is upload speeds only that they are talking about. 99% of people are almost exclusively going to care about download speed.
"At those prices, PC Pro claims it's cheaper to mail out a physical magazine than have it delivered electronically on the Kindle."
But that doesn't include the costs of actually printing the physical magazine.
Not to defend Amazon though. They're clearly trying to make a buck before commoditization of the industry drives prices down.
Those IOUs are Treasury Bonds, so if the government defaults on those, then all the people, mutual funds, companies and countries investing in Treasury Bonds are also screwed, and the US becomes a third world nation.
Real libertarians believe in voiding business contracts? I suppose we could solve a lot of the federal deficit by voiding all 401Ks and collecting the money for the deficit instead. No moral or legal problems with that, are there?
If he hacked a machine he owned or had access to, what does it matter if the manufacturer intended him to be aware of the glitches or not? As far as I know it's not illegal to have insider knowledge unless the law expressly forbids it

What argument could you possibly make that lying is right?

More than half of the 7B world population makes less money per week than a content producer would charge for a show.
All right, I guess since a glass of water out of the tap generally costs about $0.001 it isn't technically "free".
He compared it to Coca Cola coming out of the faucet for free, so why would someone willingly pay for a Coke?
Water comes out of the faucet for free, but plenty of people buy bottled water.
Does that mean they are both producing energy and not producing energy?

I'm guessing this does not exhibit the phenomenon known as "superconductivity" and is rather just a low-resistance conductor.
The state said it was not practical to provide electronic versions of the emails.
Unless you're being a complete tool, the phrases "not practical" and "impractical" can be considered the same thing.

This is why our country is bankrupt. Everyone has their little pet programs that simply shouldn't be touched, ever.
Well, that and because tax cut mania has resulted in the lowest percentage of GDP going to federal taxes since the 1940s.

No. Clusters spin. Gravitationally bound, they would have to to maintain form and not all just collapse into a black hole.

I'm fairly sure most smartphones use a combination of GPS and accelerometers for their compass functionality and not a magnetic compass.
