At 1500kW it won't be spending _extended_ periods of time charging. If you want to charge a battery for 75kWh, then 5% of that is just around 4kWh.

Assuming the thermal mass of the battery 300kg, and specific heat capacity of 2000J per 1 kg per 1 C, that's a delta of 24C. So just simply using the battery's thermal mass completely passively without any cooling is probably going to work.

Modern batteries are about 95% efficient at charging. So at 1500kW you're looking at dissipating about 75kW (100hp).

A 100hp gasoline engine needs to dissipate around 250hp of heat energy. In other words, cooling an EV is completely trivial compared to cooling an ICE car.

Pretty much all stations now accept credit cards. I think you can pay physical cash on some chargers that are attached to actual gas stations.

There is no motivation to do anything in Russia. The war is most definitely not perceived as "defending the motherland" internally, so the only remaining real motivation is monetary.

And Putin managed to build a system where regular engineers are treated as scum, while the real money gets siphoned off into the right people's wallets. This was recently demonstrated by the leak of the internal emails and source code of the system designed to send mobilization notices. It's supposed to be a part of the "digital GULAG" so that the government can send mobilization notices to the people whose disappearance is not going to be highly visible. With centralized tracking and all the related good stuff.

Its leading developer was paid around $700 a month. And was battling to get reimbursement for an extra $100 spent on a hotel in Moscow during a business trip to present their system to the chief of staff of the Ministry of Defense.

And of course, a lot of good engineers left the country in 2022 or soon thereafter.

This is easy to fix! Pentagon should just publish the list of the assets that they want satellite companies to avoid taking pictures of. To make it easier, they can provide bounding boxes and maybe tag them to make sure companies blur the images enough to not be recognizable.

It reminded me this classic ad: https://m.youtube.com/watch?v=...

No, we don't actually need housing. It's a stinking lie that is perpetuated by Democrats.

We have 1.1 units of housing per family right now. And we're near the absolute record on per-capita housing. Don't believe me?

What we need are _jobs_ that are not concentrated in the Misery Centrals (aka downtowns of select large cities).

No, kWh is not a better measure. They have a battery that can charge in 7 mins. You can then add as many of them in parallel as you want.

If you insist on another metric, then gravimetric and volumetric density would be interesting.

They should. Calculators have no place in school.

Well, yeah. It's a dirt-cheap disposable device for content consumption.

A more fundamental reason is that they switched away from Android to Vega. It's a custom OS with a React.Native-based UI. There is literally no infrastructure in it for side-loaded apps.

Pushing more and more people into dense urban landscapes that are hostile to life does not lead to happy people? You don't say...

Unironically, yes. A whiteboard or a blackboard is all you need. No videos in classroom except for special occasions.

This is incorrect. Lungs are efficient at mixing gases and so breathing SF6 is safe, as long as you give yourself breaks to re-oxygenate.

Yes, many times. I have a friend from Kenya, so I'm visiting Africa periodically. Solar in Africa is booming, and it's perfect for EV charging. Just like with mobile phones leapfrogging the fixed landlines, Africa will leapfrog global grids.

And the poorer countries will take more time to switch, of course. They'll need to wait for used cars to start coming from China. Meanwhile, people are switching from gas mopeds to electric mopeds. Uber in Kenya now has an option to get an EV bike taxi, for example.
