The typical automotive Otto cycle engine in production today is nearer to 25% efficient, and Diesels about 35% (numbers vary widely with whom you choose to believe.) As much as 1/3 of that is lost in the transmission and tires. The Ultracapacitor system is still going to have to deal with those losses, and electric motors aren't 100% efficient either.
An electric space heater is 1 kW; most modern houses have circuit breakers and wiring for 100 to 200 Amps - 11.5 to 23 kW. 1.2 MW is only 50 times the top of that range: a lot, but not enough to give a reasonable person the heebie-jeebies.
Remote station consists of gas tank, generator, and energy storage device (flywheel or ultracapacitor). Disadvantage: high capital cost compared to normal gas station. Advantage: no requirement for extra-high capacity power lines.
Insert non-printing characters into words. Use non-standard (but still acceptable) spelling whenever possible (alternate color and colour, aluminum and aluminium, etc.)
Since when is selling the assignment (actually, the student's paper submitted in response to the assignment) necessarily enabling cheating by other students? A high quality paper in a history class could eventually become part of a book, as could original work in other fields. Poetry is particularly obvious, because often the exact wording must be preserved in order to not damage the quality of the poem.
With your mention of Harvard, you reminded me of a hypothesis of mine, that cheating is rarer at top schools. Students there have already learned that their answers are more likely to be correct than the answers of a person that they copy from, making copying futile. Some of them even understand that actually mastering the material makes it relatively easy to get good grades, makes them feel better, and makes future courses and the rest of their lives easier.
I'm sorry, I can't accept this Coke you just handed me to help me stay awake while I do my homework. It would constitute unauthorized collaboration between students, which is an honor code violation and thus cheating.
Most of your points are valid, but the pressure of a sound wave is not proportional to the position of the speaker producing the sound wave except in a very small box. The actual relation is complicated, but for a reasonable range of conditions pressure is proportional to velocity.
The sampling error caused by the discrete nature of digital recordings is for all practical purposes noise. At 16 bits, that noise is about 98 db below the loudest possible signal. -98 db noise would be completely swamped by the combined noise and distortion of any analog-mechanical vinyl recording-playback system.
The "cleanliness" of a digital system is nothing to complain about; you can always add or preserve distortion, noise, hum or interference if you, the performer, or the producer want it. The difference is, with digital, the grunge added to the music is controllable; with analog, the grunge is there because of limits in the medium.
With modern amplifiers, high efficiency drivers are unnecessary and irrelevant.
Horn speakers at high volumes cause distortion because in the throat, at high levels, air is non-linear. Don't just take my word for it, charts of distortion vs pressure are printed in good books on horn speakers. (Acoustical Engineering p.224, Harry F. Olson) That's not to say that horn speakers are bad, just that they're not a panacea.
"Why should the government... permit them to pollute, harming us all?"
First, the benefits of automobiles far exceed the rather small disadvantage of CO2 emissions.
Second, the corporations aren't driving the cars, people are.
Third, all corporations, all people, pollute by the mere fact of producing and living. It is not possible to avoid. Sueing for emitting CO2 is equivalent to punishing those who live for the fact of their living. This is the essence of left-wing politics.
You obviously have no idea of the disaster for California that mandatory 100% electric new cars would be. Anyone living more than 30 miles from work, or with a mountain between them and work, would have to move, change jobs, take public transport to work, or own 2 cars (one for each half of the trip.) California would become a mecca for importing used cars and keeping old cars on the road, increasing pollution. A huge disruption in manufacturing technology would be required to support the new technology. The electric grid, already severely strained, would need extensive, expensive upgrades and would break frequently while being changed. Remember, blackouts in California during heat waves means deaths.
Good chips add more gas only at or near wide open throttle, where emission testing is not done. Furthermore, there's scant reason to emission test at WOT because you can't drive that way for a significant portion of the time.
"The standard resolution in central vision for people with 20/20 vision is about 3 minutes of arc"
Highest detectable spatial frequency at high ambient light levels, 50-60 cpd; low ambient light levels, 20-30 cpd.http://white.stanford.edu/~brian/numbers/node1 .html. A brief experiment I performed on myself 5 minutes ago indicates Stanford is closer to correct at 1 arc-minute than you are at three.
"We wanted, and asked for, an untouched version that's close to what we saw in the cinema when we were all seven years old. We got it. We never asked for "HD". We never asked for something greater than the laserdisc version."
Since what we saw in the cinema was far better than any laserdisc could possibly be, and far better than any currently available consumer product, your comment is self-contradictory. "We got it." is untrue because it is not possible, short of selling 70mm prints to the general public.
The source of opposition to this research is not accurately identified as Republicans, but rather a large swath of religious fundamentalists. That they tend to fall into the Republican camp is a historical anomaly caused by the Democrat abandoment of the South in the sixties.
Republicans and conservatives generally tend to fall into the middle intelligence range. The stupid tend to be poor and want someone to take care of them, which is not Republican politics. The very smart tend to be highly educated; those with many years of college are worn out by constant exposure to the highly liberal educational "elite". Eliminate these extremes and unmarried women, and you have a Republican majority.
Get a sense of proportion. There's very little fluorine in these new transistors, and it's chemically bound to the silicon. There's more fluorine in toothpaste, and a lot more fluorine in common refrigerants.
"If it was just the text of archimedes, then it would have been destroyed during the dark ages..."
The Dark Ages period is generally agreed to be 500 C.E. to 1000 C.E.. This copy of the text of Archimedes was erased, cut up, and written over in the 1200s. The original (or a copy of it) had survived most of the dark ages, until the most recent copy was made.
Any scheme that results in the presidential election being decided by the popular vote is an invitation to fraud. Elections are controlled primarily by the individual states, and all it takes is one fairly large state to report a 90% advantage for candidate X and the game is over.
There's too much at stake here; there's too much power available. Power attracts bad people, and sooner or later we're going to get a Caesar because the government has gotten too big. We must reduce the size of government if we're to avoid the slide into tyranny.
The Corvette is a 3000 pound car. If they're getting decent mileage (I suspect that they are fudging their figures) it's going to be much closer to a Lotus.

I've never seen a bumper-car driver lose his connection to the grid. The technology for connecting electric city busses needs to be improved.

There's a special switch for use in this situation. It's called the ignition switch, and you turn it to the "off" position.

Such as polarities. There's positive and negative, so there must be lots more.
Integers can be odd or even, so there must be lots more varieties of integers.
