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.

It is the same for software development.

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.

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.

Considering the size of the US, most birds will never see a tall building in their entire life.

But how many windmills will they see if we generate, say, 30% of our nation's electricity from wind? I don't know if bird or bat kills will be a serious problem or not, but it should definitely be researched.
