No, but hydrogen is so small that is leaks rather easily, even from vessels we would consider “sealed.” It even leaks through solid metal. We can usually deal with it, but if hydrogen is scaled up to millions of vehicles, the cumulative effect could be a problem.

But there’s also the fact the hydrogen can leak through solid metal, because the atom is so small. So even with airtight seals and careful usage, there will be some leakage, even if it’s not locally concentrated. (plus the occasional ruptured tank from accidents, etc) The question will be if that starts to exceed the…

No. Civil asset forfeiture was created for pirate ships. This is just simple liquidation to cover a lien created by the owed fees and back pay.

Edit: TIL that Penrose visited Echer, and exchanged ideas.

Cutting tile at the edge of the room is nothing new.

Worse. It’s guarantied that two sheets would not fit together properly, because it’s a non-periodic pattern.

There are several known non-periodic tessellations which use two or more shapes, and Escher was an early pioneer of many of them. But this is the first known non-periodic tessellations which uses a single shape, so that is an important distinction. (And I think Escher would be impressed.)

It’s like the digits of 𝜋 (pi). You can actually find short sequences which appear in the output, but never in a consistent distance from each other, and much more rare as you try longer sequences. There’s even a website which can do this for you, (in the first 200 million digits,) and there’s a good chance your…

International law, specifically the MLC (Maritime Labor Convention), dictates that the country where they are located must provide food and other necessities to the crew if the crew is abandoned by the owner, the expense of which is counted against the owner, or against the selling price when it goes to auction. They…

Not to mention that they fire issue seems to be caused by water. And outside is where most of the water comes from.

They probably think if you can’t find that old out of print book, you’ll have to buy a new, totally different book. They see the old books, (and especially the public domain books they can’t do anything about,) as competition to their new books.

Sony is not one of the (many) co-conspirators listed in the suit.

The argument here was that since they are salary, they get paid the same when they are working as when they use PTO, so the income didn’t change.

The paragraph about SpaceX makes it seem like they regularly do this too. But the rocket in question was an exception, one which failed to restart the engine and reenter when it was commanded to. The vast majority of SpaceX second stages do a controlled reentry over open ocean.

It’s not like they coordinate. “OK, he’s reaching. Bob, you and I will shoot, the other three don’t fire.”

I’m still using my HP color laser from 2015, with third party ink. Now I know (again) to never update firmware. Ink jets in general are a scam, but especially HP inkjets.

How is there enough hydrogen to make a meaningful amount of electricity in normal atmosphere? (I can understand it near a volcanic vent, but have doubts just about anywhere else.)

With cars and airplanes, we can easily design them with 3:1 or stronger safety margins. Most airplanes can fly with one engine shut down. They carry enough extra fuel to keep flying for more than an hour after they reach the destination.

Probably the most useful distinction would be how long it continued operating for. In the Tesla’s case that was only 4-6 hours, so it hadn’t reached very far even though it was on an escape trajectory. They should have added solar panels. But its primary purpose as a mass simulator for testing the Falcon Heavy was…

We already have many geostationary satellites which maintain constant line of sight to half the globe. But the lower orbit of Starlink, Iridium, and others is highly suitable to communicate with hand held or portable devices. It also has vastly reduced lag or ping time due to the speed of light.
