In small towns, public libraries are a resource for local history. In medium towns and up, financial databases like Value Line may be available. In all cases, as you said, libraries are a source of novels, magazines, and newspapers for free, which can be a significant benefit for those without a fair amount of available cash. Internet access is in place at most libraries, and it's popular enough that use has to be rationed.
IIRC, early in the history of blue LEDs, Sony made a silicon-insulator (PIN?) blue LED for medical devices. Silicon is not practical for modern LEDs, but it can be done.
Most rail lines are a single track. Considerable effort goes into managing the flow on those single tracks, and adding frequent passenger service complicates matters greatly. Passenger rails must be a lot smoother than freight rails, and that means more expensive maintainance.
The subject of subsidies is somewhat bogus. Yes, roads get tax dollars, but they are more than paid for -- by a large margin -- by gasoline taxes. Likewise, taxes on air travel are pretty heavy. Rail subsidies are quite different, they are paid mostly by people who don't use trains for travel.
Where I live, the maps show lots of rail lines, with (aband) written next to them. Even more common are rail right-of-ways so long unused that the tracks are long gone. Most places, even freight trains aren't economically feasilble and the idea of passenger trains is an unfunny joke.
I like passenger trains and I've used them when it's feasible. Most places, it's not.
One factor that slows East Coast train travel is stops. It doesn't make a lot of sense to run a train from Boston to Washington D.C. without also stopping in Providence, New Haven, Bridgeport, New York, Newark, Philadelphia, and Baltimore along the way.
Each technology has its own advantages and disadvantages. Inherent in ultrasound is a tradeoff between resolution and penetration. Higher frequencies have a shorter wavelength and hence better resolution, but higher frequencies are absorbed in shorter distances. Thus "deep" and "in detail" are mutually exclusive. High power ultrasound is not a solution to the tradeoff, because high power causes cavitation (bubbles), heating, and (I guess) tissue disruption. Being an acoustic technique, ultrasound is also subject to complications from refraction, reflection, and diffraction.
Of course, the "IT guy" probably doesn't have any recourse if management decides to obtain unlicensed software while employed.
Any "IT guy" who can't figure out a way to make unlicensed software crash or otherwise behave in an unacceptable manner, isn't worth being called an "IT guy".
Any business that can't afford $200 per seat to have functional software on computers, software that won't require training for a new employee, is a company that is too financially marginal to be likely to succeed in the long run. $200 is less than what the employee costs the company per day.
Did you read your own post? First you say that "tasers are not 'a replacement for guns'", then you give an example of tasers being used as a replacement for guns.
Given that deaths from tasers occur in only an extremely small fraction of all applications, 275 deaths in the U.S. alone, where taser use is not universal, is ample evidence of widespread and systematic abuse.
If TPM had been good it would have done what ANH did: run continuously to full houses(for more than a year at the Loews Astor Plaza in New York City) until it was finally re released and the bargain theatres showed it.
If he had done a good job on episodes I-III he could have created joy for youngsters and held the respect of adults. He blew it by doing one stupid thing after another, without pause or reasonable excuse.
If he didn't care what adults thought of Star Wars, then he's a fool for ignoring a large source of continuing revenue.
Insurance is attempted recovery when disaster strikes, when you have already lost your health. If you want health, you need to exercise and consume proper nutrition, not do stupid things, and not have unusual misfortune. For most people, insurance does not and cannot provide health, and the financial burden insurance imposes tends to reduce health.
My understanding of supercaps is that they are inherently low voltage devices. Technology that increases a supercap's capacity relies upon making very small structures. There are fundamental limits to how much voltage a given thickness of insulator can withstand, and I'm guessing that it's less than 1 volt per Angstrom. At even 100 volts, were not talking about "small" structures in terms of TFA.
Electrolytic capacitors will dry out unless they are very well sealed. Manufacturers specify a life for electrolytics at a certain temperature. At room temperature, they probably are not good for a century.
Plastic film capacitors will wear out if they are operated at excessive currents.
High-k ceramic capacitors degrade partially over time.
If the catalyst is useful in a gasoline -> reformer -> hydrogen -> fuel cell -> electricity -> electric motor -> power to the wheel system, and that system is more efficient than a gasoline IC engine, it eases the reliance on gasoline. Q.E.D..
If the patents were bought and buried, there would be enormous political pressure to have them invalidated, or seized outright by the U.S. government. Furthermore, there would be no restraint on China, or Russia, or India, or any other country not to rip off the technology for the enormous gains available. This also would put a the U.S. at a huge economic disadvantage, and cause the patents to be invalidated, seized, or circumvented.
Patents only last 20 years. Be patient and you can use the technology.
It's not the automotive industry that would have the motive to bury the patents; any car company with exclusive rights to such a technology would be capable of dominating the industry. Only an oil company or a cartel of oil companies could have such a motive, and even an oil company could license the technology for enormous profit.
In addition to what's already been said, platinum is very resistant to being corroded even under very nasty conditions. Thus, it doesn't get used up in the process in which it's taking part.
One of the early methods of recording sound to film used sound to vary the intensity of light striking the film. (By the way, this RCA technique was inferior.) Although the technique then probably used mechanicals to gate the light, modern technology could use LEDs for a pure analog technology to a physical medium, out to at least several megahertz. No momentum involved in any meaningful way, so your claim is false.
Furthermore, one of the early methods of recording video to disk (again inferior RCA) was physical bumps on a disk, read back by a piezo-electric sensor that probably responded more to pressure than motion. In any case, this was similar to audio phonograph technology and had a frequency response of a few megahertz, well beyond any audio frequency range limitation.
"Brick wall" filters do not necessarily mess up the time domain response. All they have to do is be symmetric FIR designs, which is generally the case.
They've got all these developers they can't find work for, and they won't at least ask if someone would like to work on a problem that happens to be in userspace?
In my limited experience, userspace work is easier and less destructive if defective, compared to kernel work. A bored developer should jump at a chance to do something helpful, even if it isn't in his preferred niche. That it is easier should be a bonus.

The reason blue LEDs have switched technology is that the new stuff is much more efficient. Cree still makes SiC crystals, even for jewelry.

Firestone was bought out by Bridgestone.

The system to destroy asteroids (project Icarus) was done 40 years ago. It got good press at the time.
