Curious to see what the economics of starship will shake out to be

Those are normal crystalline panels, not tandem

Are there any perovskite/monocrystalline cells in commercial production yet anywhere in the world? I keep seeing a lot of buzz for adding a perovskite layer to crystalline silicon cells, but I’m not seeing any in actual production. Maybe I’ve missed something?

Wow that’s terrible design

Israel does this all the time. Prisoner / hostage swap is pretty much standard operating procedure. It’s why Hamas took hostages in the first place. Israel already traded back 240 Palestinian prisoners during the first truce back in November.

What’s going on now is negotiations. How many prisoners, exactly which ones, etc. The specific prisoners is likely the more salient point because Israel has effectively an inexhaustible source of Palestinian prisoners. It’s a renewable resource. Meanwhile Hamas needs decades to plan a border raid so it can get a few hundred hostages to trade away.

After the 10/7 Hamas attack, one of the biggest fears that Israel had was that Hezbollah would join and attack Israel from Lebanon. Hezbollah is one of the most serious existential threats to Israel, so it became a priority to prevent them from joining the war with Hamas.

That meant stepped up rocket and drone attacks that was intended to signal strength and serve as a warning to Hezbollah. Of course Hezbollah did the exact same thing with rocket and artillery strikes against Israeli targets, also intending to signal strength. These cross border attacks basically started up immediately after 10/7 by both sides.

The attacks have escalated slightly over time, but have not escalated into full out war. Neither side really wants to go to war right now. Israel is focused with its war in Gaza and wants to keep Hezbollah from joining. Meanwhile it’s the perfect opportunity for Hezbollah to attack while Israel’s attention is split, however that has to be balanced by the fact the vast majority of Lebanese people oppose going to war because it would devastate their country that’s already in the midst of a many-years long economic, political and social crisis. So Hezbollah is effectively prevented from joining the war with Israel by internal Lebanese issues.

Most likely the border attacks will continue as they are without escalating into an all out war that neither side is really prepared for. Unfortunately the immediate result is that entire communities on both sides of the border have become internally displaced. The article mentions ~100,000 Lebanese have fled their homes in the border region. The numbers I’ve seen for Israel are also >100,000 people evacuated from their communities near the border.

Yes, that is how active sonar works. The ship emits a very loud noise and listens for reflections to map out the surroundings. Sonar pings can be very loud and can damage the ears of underwater life forms.

Wait, are you saying Bin Laden’s propaganda isn’t a good faith argument?

From the second paragraph of the article:

These remarkable findings position elephants as the first non-human animals to use a form of address that doesn’t mimic the receiver’s call, a trait previously observed in dolphins and parrots.

It appears dolphins have a “signature whistle” that they produce and other dolphins use this like a name. Sort of like if you enter a big room and yell out “Wazzup” and then everyone starts calling you Wazzup.

Elephants appear to be different, seems like they will name other elephants. Sort of like you enter a big room, the other people notice you’re short and everyone starts calling you Shorty.

That was interesting how they adjusted sizes based on adjacent letters. Good idea

Yeah they really buried the lede here. The big news is the claim that they can sell cultured carrot cells for cheaper than grown carrots. The 3D printing part is besides the point.

Also the carrot shape isn’t really ideal for cooking. Annoying to split into smaller pieces. If you have the freedom to print it in any shape then I’d take big blocks personally. Much easier to stack, store and cut into arbitrary shapes for cooking. Molds definitely seem like a better idea for mass production than slow 3D printing.

Here’s a video of that .exe running:
