Right, 200 cycles is too short. These don't even compare well with Panasonic's current NCA cells, which are reported as 675 Wh/l. After 300 cycles the Panasonics probably store more energy.
You DO understand that the Bolt is just a Chevrolet Spark with an electric drivetrain?
It's more similar to the Sonic, but it's not exactly the same. I'd withhold judgment until I could test drive one, or had at least read independent reviews.
Trans-fats have been disappearing from the marketplace for some time now. Crisco used to be a big source but they've been trans fat-free for years. I still occasionally see cookies with trans-fats but I don't buy them since there are alternatives without.
In most of the developed world, the birth rate is either stable or in decline.
That's is true for now, but if we let people self select who breeds we'll end up with a population of those with a propensity to breed; either socially or biologically. We're going to have to stop that someday, somehow. I'm confident that it's far enough in the future that I won't have to deal with it.
In 2000 years the drums might get sucked down 100 meters or so. It would be better to drop them into the mud in the middle of the abyssal plain. Personally, I think we should keep them more available; they might be useful someday.
The difference between the 60kWh and 85kWh Tesla Model S cash price is $10,000 or $400/kWh so I'm not sure about the article's conclusion that the battery costs $300/kWh.
In addition to the other points mentioned elsewhere, the 85 kWh Tesla includes access to their charging stations, which is valued at $2,000.
I'm very suspicious of the idea of used battery packs being used for grid storage.
However, lithium is cheap and is well understood. I think Tesla could devote some of their production into non-cobalt based cells, and possibly non-nickel too, and use them for stationary storage.
FYI, a kilowatt is a unit of power, i.e. a rate of energy transfer per time. 21 kilowatts means you can move around 21,000 joules of energy per second.
A 'full charge' depends on the amount of total energy the battery can store, i.e. units of simply joules. Joules are pretty small and energy for batteries is often expressed as kilowatt-hours; 1000 watts * 3600 seconds = 1 kilowatt-hour = 3,600,000 joules.
So, 86 kilowatt-hours is about 310 million joules. If you charged a 86 kilowatt-hour battery with a 21 kilowatt power supply, it would take 86 / 21 = 4 hours to charge.
I was going to point this out, but Mister AC beat me to it. You rarely run a Tesla down to empty in a day of local driving. Also, most places in the US get between 5 and 6 hours of sunlight per day, although it can be much less in winter if you're anywhere near Canada.
No, that's methane. Any carbon dioxide cows produce will be transient. Methane will eventually decay to carbon dioxide, but it will take decades. Still, that's short enough that I don't particularly care about cows.
True enough, and perhaps the scientists think so, but it's being reported as "...this will directly correlate to an exponential rise in the levels of atmospheric" carbon dioxide (from the article).
How is this supposed to be a problem? The plants are sucking out more carbon dioxide from the atmosphere while they are growing, then releasing as they decay. It's interesting that it is noticeable, and bravo for measuring it, but I don't see any troubles that this will cause.

It is transparent to all colors. What's wrong with calling that colorless?

I saw it, but I wish I hadn't. It's a terrible movie.
There is microeconomics, which is pretty sciency. Macroeconomics is more sociology.
Have you seen the size of those reports? Have you tried stay awake while reading them? It would be more appropriate to say: "It really is that hard."
What clouds?
We're well on our way to getting one built in Carlsbad, near San Diego. I hope there are more to follow.

Off by a factor of two. The cruising speed is almost 500 knots.

The End? Where's the kaboom? There was supposed to be an earth-shattering kaboom!
Unfortunately, we're near the end of the rainy season now. There's not much hope of an El Niño fixing the drought this year.
According to Wikipedia, Berserker was first by a year. I am more reminded of Laumer's Bolo series, anyhow.

More prosaically, and more accurately, I can predict the Sun will rise in the morning, or that it will be colder here in a month.
The USA is only the fourth largest country by area (Russia, Canada, China).

I don't think so.

I can agree the gas tax needs to go up, particularly the federal one. Will congress agree? I doubt it.
Everyone gets an equal share of it back. Trying to keep the government's hand out of it is the hardest part.
