> Sales of Tesla's electric Cybertruck fell 48% in 2025, new data shows.

> Tesla sold 20,237 Cybertrucks in 2025, down from 38,965 the previous year, according to figures from Kelley Blue Book's annual electric vehicle (EV) sales reports.

> A federal safety report shows that Tesla is recalling 63,619 of its futuristic pickups, and this seems to be the total number of Cybertrucks built since the first one was delivered at the end of 2023.

> Musk said that it's time to put the Model S and Model X vehicles to rest. Now it's not that huge of a change, given that 97% of Tesla's sales consist of Model 3 and Model Y cars, but the Model S is still the original car delivered by Tesla.

> The financial report paints a grim picture for the company. Tesla's total profit for 2025 was €3.24 billion. That is a lot of money, whichever way you look at it, but it is actually 46 percent less than what the company made in 2024. The profit margin, which is the percentage of money the company keeps after paying expenses, fell to just 4.9 percent. In 2022, that number sat at 23.8 percent.

> One of the most interesting parts of the financial report is how Tesla made its money. A large chunk of its profit did not come from selling EVs to people. Instead, it came from selling "regulatory credits" to other car companies that need help meeting pollution rules. These credits brought in €2 billion.

> That means 52 percent of Tesla's entire profit for the year came from these credits, not from selling vehicles. If Tesla did not have those credits, the financial results would look much worse. And the problem the company is facing? Those credits are gone; they won't be part of Tesla's business model this year since they were cancelled by the current administration.

Tesla is betting on long shots like humanoid robots and self driving taxis everywhere. There are other desperation moves like merging Tesla (profitable) with SpaceX (I think it's also profitable? but most of its business is governments: risky markets) and xAI (most likely wildly unprofitable, just like Twitter).

> with the worst profit margins

The 2025 profit margin for Telsa was 4.6%. Toyota's was 9.4%. Telsa is famously on a multi-year sales and revenue decline.

Clearly 200 forward P/E and three consecutive quarters of missed earning is a sign of profitability.

It's a stock worth $50-60 with generous valuation. The premium is the Elon bullshit and grift. That isn't gonna last forever.

Keep up.

Just ask this scientician.

> Yeah he only micromanages (look at his old blog) every detail he has time for at an extremely successful aerospace engineering company, just an ideas guy.

Have you ever spoken to someone who works at SpaceX? I have multiple friends in the industry, who have taken a trip through the company.

The overwhelming consensus is that - in meetings, you nod along and tell Elon "great idea". Immediately after you get back to real engineering and design things such that they make sense.

The folks working there are under no delusion that he has any business being involved in rocket science, it's fascinating that the general public doesn't see it that way.

What kind of the problem you're talking about compared to existing satellites? That is, all existing satellites generate power, and need to dissipate that power, and most of it goes to waste heat, and the satellites somehow do that successfully - what is the specific problem you're talking about, which can't be solved by the same means?

It’s a vacuum

Does this mean that if Earth stays a fixed distance from the sun then its equilibrium temperature is fixed? I remember people saying things like that the albedo of the ice caps affected the Earth's temperature.

Space is cold because there isn't anything there.

There is also no matter to wick the heat away.

Yes and no.

If you had a thermometer that had no heat generation then yes.

If you have a resistor or other heat generating circuit then you need to have the needed surface area to radiate the heat away. If you don't, it will heat up. It's a rate problem.

There is no matter.

It's cold there because there isn't anything there.

So there is nothing to conduct or convect the heat away.

It's like a giant vacuum insulated thermos.

Is putting data centers in thermos' a good idea?

what thermometer would you use to measure the temperature of space?
