Gallium arsenide makes some of the most efficient single junction solar cells. Arsenic isn't among "some of the most toxic chemicals known to man" but it is still plenty poisonous. Your point about ordinary solar panels is, of course, correct.
You're only listening to one side of the news. In New Hampshire, evidence of illegal voting has been announced in the last 2 weeks - mostly in college towns where the votes tend to be strongly Democrat.
The US has a bad deficit problem because of government intervention in the free market. In this case, the U.S. government is in effect borrowing from other countries to pay for social programs like welfare, medicare, social security, etc.. The details of the money flow are more complicated than that, but the bottom line is that if the U.S. government stopped giving away money (and stopped using the Federal Reserve to cheat everyone on the planet) the trade deficit would disappear quickly and the national debt eventually.
To the extent that politics affects gasoline prices, in recent years it had been Democrat politicians whose intended actions would make prices higher. Such actions include prohibiting drilling and attempting to prohibit fracking.
Strong typing seems like a good idea until you download a large legacy program and it won't compile because the language has been redefined to enforce stronger typing. Then you look at the particular error, and find that the type name has been aliased, and the alias has been aliased, and so on ten deep. Repeat for dozens of variables, and 2 days later than nice program that was going to save you a couple of hours still won't compile.
How many types of casts does C++ have to get around the strong typing problem? Can you figure out what each one actually does, and which one to use in a particular instance? Why does it seem that none of them claim to do what I need done?
People on slashdot frequently claim that humanity should be wiped out, and it's not uncommon elsewhere. Hatred of most of humanity is standard issue rhetoric from the political left.
Also include a button that resets all preferences to their defaults
I just spent 2 hours setting preferences to where I want them. Now I'll press the OK button -- oops! Reset All. It needs at least a warning and an "Are you sure?"
More expensive and more time than a conventional railroad, probably close to the cost and time of a 4 lane interstate highway. Roads require a lot of surface preparation, but a big ditch isn't terribly tough.
My quick calculation reveals that evacuating a 1 mile tunnel 20 feet in diameter with a perfect mechanism would require a 1000 horsepower engine running for 1.6 hours. Water in the tunnel would take much longer.
Better have those passengers strapped in. Some guy walking around while the train decelerates at 19 g is going to be a nasty stain, and probably kill anyone he hits.
The hyperloop will already be traveling at the speed of sound in the atmosphere, so even a massive breach behind it won't add to the speed in an uncontrollable manner, if at all.
I haven't seen the design for a hyperloop rail, but it is a trivial task to design a rail that would make derailing impossible. For an example, look at a roller coaster.
Vacuum isn't a magic force that overpowers the ability of all but the finest designs to keep its container intact. The design has to withstand the pressure differential, just like any underwater tunnel. Like the tunnels under the Hudson River, the East River, the Harlem River, and the English Channel. Eight of the New York City tunnels are over 100 years old.
The effects of derailment would depend on tunnel design and other design details. I think the design could be made to keep the train inside the tunnel and pointed straight ahead. Friction of the train body on the rails and tunnel walls would bring the train to a gradual stop. Then the worries become "Can a breach of the car's atmosphere containment be survived?" and "How and how fast can the passengers be rescued?"
Ordinary train crashes can be fatal because once off the rails, the engine and cars can run into trackside obstructions and decelerate faster than a body can tolerate, possibly while tumbling.
This can get funny. There are rare cases of people who naturally have gut or mouth bacteria that process food into ethanol. They can get drunk (and be a hazard on the road) without consuming alcohol.

Interestingly, Texas has almost 3 times the wind power generation of the 2nd-most-capable state (Iowa).

"You imagine" is correct. Minimum wage bears little relation to actual wage.
Suffering leads to efforts to reduce suffering, which leads to progress.

Why turn it on before brushing? Don't you have saliva?

People who claim that must not be counting all the new species that are being created by humans.
If the Apocalypse comes, everything is destroyed and money has no value because there's nothing to buy. Fools and cowards buy insurance.

All conventional non-trivial definitions of god lead to contradictions. Things with contradictory properties cannot exist.
The "conventional non-trivial" qualifier is there to prevent silliness like pantheism and "this rock is god".

You can't even stay on subject in your first two sentences. Hint: crash and accident are 2 different things.
If the tube is bent inward into the path of the train, derailing is a minor problem in comparison.

Can you teach someone to be this stupid?
