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.
It is transparent to all colors. What's wrong with calling that colorless?
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.
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."
Banning the trading of certain goods which aren't inherently harmful by themselves seems like a dangerous precedent to set.
The precedent was set by the outlawing of gold bullion ownership. I'm glad that's over, but governments have not promised to never try such a thing again. The control of the money supply is important to them.
Maybe robots could build desalination plants?
It's pretty damn sure that humans never will
We're well on our way to getting one built in Carlsbad, near San Diego. I hope there are more to follow.
... in 2000yrs
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.
747s cruise at several hundred knots, around 250 IIRC.
Off by a factor of two. The cruising speed is almost 500 knots.
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.
