Goal posts: moved!

Now we have gone from "it's impossible to combine renewable energy and storage to get reliable power" to "only rich people could ever afford it".

In my case, I have a ten-year loan making the monthly payments possible for me. I know someone who has a 20-year loan. These long loan periods only make sense because solar panels and lithium batteries last for decades.

My home isn't that large but it's all-electric. Electric stove, electric clothes dryer, heat pumps for heating/cooling the house and for heating water. It's why the solar company recommended I get 30 kWh of batteries. If Tesla Powerwall 3 had been an option when I got my system, two would have been enough.

And you must have missed the part where I said the costs are falling. When the Macintosh computer was first sold, it cost about as much as a new economy car. I guess computers are only for rich people even today, right?

You really didn't contribute anything to the discussion.

the largest battery farm you can reasonably buy for a residential system.

Really? How large are we talking?

I have 30 kWh on my house, and that easily lasts all night. Even while cooling the house in summer.

In winter I don't get much power from the solar panels, but for about 2/3 of the year my roof can charge the batteries while running the house. I live near Seattle... I'll bet people in California and Texas really could run their homes year-round from solar.

In short, my personal experience disproves your claims.

Now, I am fortunate to be able to afford the large batteries and solar power system... but the price has already been falling and it's expected to fall a lot more. So I am not some 1% elitist. My point is that if my house is as good as it is in gloomy Seattle, there's huge potential in places like California, Texas, India, etc.

Until recently grid-sized batteries were science fiction. Now, Google "Tesla Megapack" and see how many utility companies are buying them.

My thought experiment is, what if two black holes were approaching each other very rapidly on a not-quite-collision course, so that the sides of their event horizons briefly overlapped as they passed. Would they stick together?

ISTM that if anything was inside the overlapping area they'd have to stick, since otherwise that thing would be escaping from one of them. But is there anything there? Maybe something that just now fell in and hasn't had time to fall to the center? Or, is there quantum foam inside a black hole, and if so, would that count as "something" that would force the black holes to stick?

The underfunded state of the FAA has forced SpaceX to launch less often than than they would have were they not waiting on overworked FAA officials to approve launch licences. SpaceX's development model is to iterate quickly: design, build, test (launch), redesign, build, test (launch), etc. The FAA's pace of delivering launch licenses has slowed this process down to the point where SpaceX scraps Spaceships that they would normally have flown but could not because SpaceX builds the biggest rockets ever built faster than the FAA licenses.

SpaceX already proposed LAST YEAR to finance the FAA so that they can staff up to the level SpaceX will need them to be, making TFA's baitclicky "Biden Takes Aim At SpaceX's Tax-Free Ride In American Airspace" about as close to reality as utterances from Trump or Putin.

The most recent story on the Havana Syndrome before this was that there was no evidence it was caused by any physical damage. The conclusion was that its not actually a "syndrome" but random symptoms with no common cause.

Whereas the correct conclusion would have been that it is not caused by anything that causes physical damage that we can detect.
