The numbers are close to correct. Solar irradiation is not the same as human energy consumption. Multiply 1 kW/(square meter) by the area of a disk with 6400 km radius, then muliply by a little more to compensate for atmospheric losses in the 1 kW figure.
The error is to say that the energy is beamed; it's not. It's broadcast.
The average human generates about 100 W continuously from the food he eats (do the math). If a satellite aims 50 mW at your kid (or if not at your young goat, then your child), it's only one twentieth of one percent of what he generates internally. And you'd kill someone for that?
Google's anti-competitive practice is the most powerful one: doing a great job. This effectively overcomes all competition. Destroying all greatness in the USA is Obama's goal.
Your daughter is not a dog or cat who will not understand punishment that comes 5 hours later. She comes home, you take her phone and destroy it with a hammer in front of her. Other punishments may be appropriate; the girl in TFA obviously is a longstanding behavior problem who has gotten where she is by lack of parental control for many years.
If you went to a school that grouped people by accomplishment (another thing liberals are trying to prevent) this would not be a problem. You'd be with people who actually were there to learn. Pests would be in different classrooms.
All recent history and CPU related. There are so many different and interesting failures in chipmaking history. Serial memory. Silicon-on-sapphire. Gallium-arsenide CMOS. The decline of bit-slice designs.
The problem is that an entity in a foreign country is much less sensitive to complaints about abuses of the system. There's no chance you'll meet the CEO and badger him in a loud voice in front of 50 people about how he's stealing your money.
Lincoln did not end slavery, not even in the U.S. (Nixon did that, when he ended the draft). His public actions against slavery applied only to states over which he had no control, as any honest historian will tell you.
Lincoln introduced an income tax, suspended habeus corpus, and viciously supressed freedom of speech and assembly.
By insisting upon preserving the union, he caused the deaths of more North Americans than any president to this very day.
After the suppression of Shay's Rebellion (1787) and the Whisky Rebellion (1794), Lincoln's Civil War is the most significant advance of big government over freedom in our history.
The greatest American President ever? Hah! People should spit at his memory.
Assuming that one of your suggestions (propellers) is actually serious, there are a couple of issues. One is that the propeller still has to be powered by something, like a.. a.. jet engine. Another is that as noisy as jet engines are, props are noisier. Research on props hasn't stopped entirely, and every decade or so Popular Science or some similar magazine will showcase a weird-looking propeller design that features high efficiency or low noise.
Had we not allowed human population to explode as it has...
The words you choose are very revealing. Who is "we"? What do you mean allowed? Do you think someone has the right to prevent someone else from having a child? By what method? (At gunpoint, what else.) Yours is the attitude of a tyrant.
All 4 references give the time it takes to generate the energy equal to the energy required to make and install the windmills. This is interesting, but in an economic sense it is almost useless. We need to know the time it takes to make a windmill pay back the costs of getting it online. A solid gold windmill may pay back its power costs in 6 months, but it will never pay back its economic cost.
From what I see, religion and science aren't necessarily incompatible.
Religion and science are fundamentally opposed on the issue of epistemology. In science, everything has to be compatible with observations or it can't be properly claimed to be true. In religion, truth is established by authority: the preacher or the bible or (fill in the blank) says it's true, therefor it's true.
This explains why some people are so enthusiastic about finding errors in religion. Logically, once the flaw is found, the authority is dethroned, and the whole religion should collapse. Alas, religious people can be remarkably immune to logic. So although it is worthwhile to point out religion's inconsistencies (both internal and external), it won't change the mind of most people who want to believe.
As an illustration of the division between religion and reality-based belief systems, consider what happens when something in religion is found to be in incontrovertible agreement with observations. If it's an old event, then the item ceases to be religion and becomes history. If it's some principle of behavior, then it ceases to be religion and becomes part of the soft sciences like psychology or political science, or (worst case) part of the humanities such as ethics. When something is proven, it's no longer religion.
Deep space may be cold, but vacuum is a superb insulator. The chips can't be pushed hard without extensive and expensive heat sinks. Considerations on deep space probes are reliability and low power consumption, and there isn't a lot of need for speed. Reliability, radiation hardness, and low power consumption all have requirements that oppose speed.
Furthermore, since space probes take a long time to develop and use only very well established technology, they are using nearly-obsolete semiconductors by the time they're launched. They're really old when they get where they're going. It's not fast stuff by today's standards.
Leakage is not a direct function of speed. Thin gates and short transistors leak, and they are necessary for high speeds. Higher voltage increases speed and dramatically increases leakage. Lower temperatures decrease leakage.
The primary effect of low temperature is to make FETs conduct better. This reduces switching time, so the CPU can be run faster.
Another upside of government investment is that they can invest in things that benefit society as a whole, whereas private investors are only interested in investments that benefit themselves, personally. The tragedy of the commons sums up the failure of capitalism, and why socialism is so important. People working together for the benefit of all achieve more than people trying to better themselves even if it fucks over everyone.
Your claim opposes human nature both in theory and in practice. People working for anything but themselves have diluted incentive. They have very little interest to work hard, or to work at all. Whatever they do or don't do, they get to participate in the results, whatever they may be. People working for themselves get all the results of their efforts, so if they do nothing, they get nothing. Leftists generally ignore INCENTIVE, and it is extremely important in human action. Rational people do everything to further their own interests, and as a byproduct benefit others.
Government projects lack the incentive to actually benefit anyone but politicians, and what they want is to get power over others rather than actually help others.
Because home computers create a lot of EMI, they're enclosed in metal boxes. Those same metal boxes help protect them from EMP strikes. The vulnerable components are those connected to the world outside the box: keyboard ports, monitor ports, printer ports, external USB, firewire, SCSI, modem, etc.. The parts likely to blow are those interface components, not the microprocessor, which is protected for a variety of reasons including its price. However, if the interface parts are gone, the computer is useless, so it's not much of a consolation that the micro won't be fried.
The most likely way to kill the micro is a surge on the AC causing a severe overvoltage to the micro.
Telegraph wires were exposed and extended over long distances, so it's no surprise that any sort of electrical storm could interfere with telegraphy. Modern telephone and electrical systems are designed to withstand most lightning strikes, so they stand a fair chance of holding up under a sunstorm. Time will tell.
You missed the point. Leaders of the environmentalist movement want those nearly 7 billion humans to die in misery, so as not to damage their precious earth.
Take a look at the advertised efficiencies for gas furnaces -- they're not 100%, although they can exceed 90%. If you want 100% efficiency, you'll have to burn every molecule of the gas and not vent any of the combustion products to the outdoors: Charles Darwin would like a word with you.

It appears that teaching English is also a losing proposition. That doesn't mean we should stop.

Would the vortices be a problem for tail-mounted engines like the Boeing 727 has?

Actually, at temperatures that low, speed-of-light limitations can be as significant as transistor switching speed.
Thanks, we'll separate them into useful parts and sell them back to you as finished goods.

It would take spectacular dishonesty to fudge the energy to make a cup of tea an order of magnitude lower.
The skepticism shown in this thread is fully justified.
Efforts to operate more efficiently are not helped by fallacious arguments and mindless cheerleading.
