Cui has previously touted results of a different battery after only eight cycles, so 150 is quite an improvement. They are still a long way from having something ready to sell, and they don't claim otherwise.
I think you ask too little. What get me are quotes like this;
The team is looking at a price point of $25,000 for an EV battery range of 300 miles, which would be competitive with a 40 mpg gasmobile.
That's not actually what the team said, it is a paraphrase of something Chu said about what is desirable in an EV. The author apologizes in the first comment.
Don't blame the researchers for the idiocy of the article's author.
150 charge/discharge cycles is not very much. That is only 5 months use.
Initial testing of batteries is usually done at C/20, or less than one cycle per day. I don't know if they sped this up any, but it would still take quite a while for 150 cycles. You're asking too much from a research project.
By the year 2200, sea level is expected to rise somewhere between 4 and 30 inches.
A more reasonable guess might be around a meter by 2100, plus or minus a half meter. What will happen in 2200 will depend too much on our actions before then to say much.
...this for ex (300 miles of power) which was just announced...
There is a lot of marketing speak at your link, and very little technical information. Some of it is just wrong, like the implication that rare earths are heavily used in batteries. My bet is it is a scam.
I watched the show. I may have missed the final episode (I don't remember) but it definitely lasted more than one season. It was a lighthearted children's show, and your ending would be completely out of character for it. I believe Wikipedia.
Pure water, without any dissolved gasses, has a substantial tensile strength. It is not theoretically stable, but in practice it is. Enough so that a siphon will work in a vacuum.
Indeed, but you should also mention it should have been "you're broke". It's obvious, of course, but it happens so often that some might have missed it.
The current Tesla cells are too expensive for grid storage. Nickle and cobalt are not cheap. Nothing says they can't make two types of batteries though, nickle cobalt for cars and manganese dioxide or iron phosphate for the grid. Or they could have a nice lithium sulfur chemistry they could use for both; there has been a lot of recent development in that area.
...D2O which is expensive but abundant (it makes up about 1 part in 40 million of water molecules)...
That 1 part in 40 million figure, while not wrong, is misleading.
Quoting Wikipedia:
It [duterium] has a natural abundance in Earth's oceans of about one atom in 6,420 of hydrogen.
So the hydrogen in the ocean is 1/6420 deuterium. Getting two of the deuteriums into one molecule is rare, but we don't really care. Chemical bonds are unimportant energetically compared to nuclear reactions.
A builder builds a wall. A week later, bricks begin to fall out of the bottom, but he continues to build the wall higher. In most cases, he would have to replace those lower bricks at his own expense and on his own time.
If the builder is an independent contractor it will depend on the bid. If it is time and material he won't, but if the contract is for the job he will. If the builder is an employee he is never responsible: He either learns not to do that or he should be fired.
Carlsen played a non-standard opening and included an unsound sacrifice. He had probably looked at the first few moves for his blitz games, but no deeper since he would never play it in serious games.
Gates had two minutes for the entire game. For someone who is not obsessed with chess that is not enough time to make even sort of good moves.
It's a 50-200-250 three way, and that is the 200 watt level. A pure 200 watt bulb would be even brighter. At 250 watts it is 4240 lumens, but I rarely use that.
My guess is, shitty hardware. I've never seen this happen unless the batteries were bad.
The UPS was brand new and from a reputable source. The computer, not so much. I wouldn't have expected the computer type to matter if it could run on line power, but apparently it did.

At one cycle a day that will take awhile.

We just need better robots!

Way to go, Al. The stupidity of your colleagues was supposed to be a secret!

Something is wrong here. Small Wonder lasted four years, and the last episode description doesn't match what you say.
Not much electricity comes from burning coal out Stanford's way.
Pure water, without any dissolved gasses, has a substantial tensile strength. It is not theoretically stable, but in practice it is. Enough so that a siphon will work in a vacuum.
Such pure water is hard to find, though.

We do it now. What is NaN/NaN? NaN.

It is the same for software development.
The lack of living grandparents probably has a negative effect on a child, or even might prevent his birth. Not a large effect, though.

They are never bright enough.
I just checked, and I am using a 3660 lumen bulb for reading. I've yet to find any CFL or LED light that comes close.
Of course, nobody has talked about banning them, but I'd like to switch if I could.
The UPS was brand new and from a reputable source. The computer, not so much. I wouldn't have expected the computer type to matter if it could run on line power, but apparently it did.
I have had that problem, though. I guess it depends on what hardware you have.
Why do these things always make the main page a day late? I had to search for this.
Took me almost an hour, a lot of which was trying to figure out "one way to store data".
Wow, there's a ton, but it is hard to think of them out of the blue. A few were:
Silent Running
Galactic Quest
Real Genius
Short Circuit
Men in Black
The Last Mimzy
Good questions, actually. The interviewer was an idiot.
