Pour une voiture, cet effet est de l'ordre de microgrammes, donc somme toute négligeable par rapport à tout ce qui peut se passer autrement.

A noter qu'il y a aussi des types de batteries qui ont leur masse qui varie en fonction du taux de charge, car fonctionnant en système ouvert. Typiquement les batteries métal-air sont comme ça : tu fait rouiller pu dérouiller un métal avec l'oxygène de l'air.

He should have used a 2000 y.o. equipment. Romans knew how to defeat drones: https://en.wikipedia.org/wiki/Retiarius

En même temps, maintenant tu parles de ça au lieu de parler de la loi. Il a réussi son coup.

It means that U.S. automakers find it cheaper to have their vehicles made in China and then import them in the U.S., rather than make them directly in the U.S. in the first place.

This means that manufacturing in China is so cheap that even with the tariffs, it is more cost effective to go there. If your goal with the tariffs is to level the game, then this should not happen (no one would relocate like that unless there is a massive gain).

This.

I don't mind if they use the average household number in the title or header, that's understandable. But such an article should have the actual values somewhere.

Can we? Yes. Should we do it right now? That's debatable.

The question is how much this would cost vs getting a two weeks offline every 26 months?

These two weeks do not create any additional requirements (you already have to make sure the probes can survive for a few weeks without comms), science does not fully stops during these two weeks. And it gives an opportunity to do long duration maintenance on the ground segment.

Frankly, there is little need to spend >$100M for such relays satellites until we actually have a permanent human presence on Mars.

That will be a nice explanation when they arrive in prison.

That's interesting, it looks like I may have a bias on that due to my scientific background.

I always said salt, of sodium chloride for NaCl. Who is using sodium for table salt? The only time I heard that associated was when saying that table salt is a source of sodium, which is true.

Most likely because the news is in English. And why would Natrium be better on an international forum?

It is Sodium in most Latin languages (despite Natrium being Latin), in Hindi and in Arabic. And Chinese has a different root. Among the 10 most spoken languages (according to Wikipedia), only Russian is using Natrium.
