Unfortunately that inside source is often coached by the PR department and are just there to say things they can't get away with saying publicly or don't want to have their exact words on record. I.e. just as much a misrepresentation as the official press releases. Or sometimes even more of a misrepresentation since nobody can actually be held accountable for their words.

No they didn't. They had a hiccup in 2020 when the transition to electric cars really started accelerating but after they got their own electric cars into mass production they've reclaimed the top spot at 13.9% of the Chinese market. That's just ahead of Geely at 13.8%, Toyota at 7.8% and BYD at 7.1%.

It was hard to find reputable numbers for all of Q1, so my source is only for january and february: https://www.reuters.com/business/autos-transportation/volksw...

In a nuclear energy context "closed cycle" just means that the uranium and plutonium is separated out from the spent fuel for future reuse. The loop is only closed in the sense that some of the spent fuel material that leaves the reactor will enter it again in the future. It doesn't imply that new inputs won't be added to the loop.

A lot of normal people I know used to love maps.me but have become dissatisfied with the ads and other unwelcome commercial elements. They would definitely chose coMaps over Organic Maps just to lessen the risk of that happening again.

Yeah, with how much focus there is on the capital costs of nuclear power plants it's easy to forget they also have moderate operating costs. With the developments we're seeing, you're right that the LCOE of solar and wind is or will soon be lower than the operating costs of nuclear. That leaves the only remaining upsides of nuclear being production stability and energy diversity, and grid batteries are making the first less and less important every year. Not to mention that the capacity factor will be pushed down from the demand side worsening the costs even more since not all operating costs are proportional to the amount of energy generated.

Quite a lot of open source hardware is licensed under the BY-SA Creative Commons license which is an actual open source license. E.g. the Arduinos and things like the Milkymist One which can actually run linux.

An already built nuclear plant is cheaper than building new solar and wind, which is what this article is about. It had already started operational tests at 5% capacity when it was shut down.

And nuclear power doesn't inherently emit CO2 (or equivalents), which is what is meant by zero-carbon in this context.

If your location already has a well-run nuclear energy sector (Finland, Sweden, South Korea): invest in nuclear energy.

If you don't: stick to renewables.

And it also depends on what you mean by "we". As a Dane, I don't think us Danish taxpayers should invest in nuclear energy, but I'm perfectly happy that private Danish investors invest in Seaborg/Saltfoss and Copenhagen Atomics.

Cool game. Too bad you didn't include "oranges" on #4

DRAM hit a barrier at 10 nm a few years ago[0], so 16 nm is actually even closer to state-of-the-art. E.g. Micron newest node (1-γ) is their sixth at 10 nm [1] and their first EUV-based node.

The problem is that DRAM is fundamentally based on storing charge in a capacitor and how much charge a capacitor can store is a result of the geometry of the capacitor. So either someone will have to figure out a way to make the same size capacitor take up less space on the RAM chip (this is what broke the previous 20 nm barrier) or someone will have to invent a practical way of making RAM with less than 1 capacitor per bit.

Hmm, so memory is actually still cheap compared to historical highs. At least cheap relative to other computer components.

France does have parallel gas infrastructure though. It's, funnily enough, at around 10% of their electricity supply.

I don't see that?

France: 4.12 tons CO2 per capita Denmark: 4.34 tons CO2 per capita

and the electricity price for industrial costumers is also close to identical:

France: 0.153 EUR/kWh (0.130 EUR/kWh without taxes) Denmark 0.122 EUR/kWh (0.121 EUR/kWh without taxes)

The four APRs built in Abu Dhabi cost $32 billion in total and the two they've contracted to build in Czechia is projected to cost $18 billion in total.

Just a small nitpick: Renault isn't Stellantis and have been quite competitive (if a bit timid) in the EV space. First with the Zoe and now with the Renault 5.

Well, there are no disclosure requirements on Deployers because doing any kind of training or fine-tuning automatically makes you a Provider.

SoftBank "only" lost around $10 billion on WeWork. The SoftBank Vision Fund alone invested more than $100 billion in various companies.

36 mpg is 6.5 l/100km. That's only a smidge better than the most efficient Renault Espace from 1999: https://www.auto-abc.eu/Renault-Espace/g988-1997

Dropping these regulations won't help the competition either.

Damn, it sucks that people are allowed to get away with that kind of speed. Here in Denmark the mandatory minimum for doing over 200 km/h is losing your license for 3 years, confiscation of the vehicle and a ~$2000 fine. Unfortunately punishment isn't enough to get rid of this thing as around 1000 cars are confiscated each year. Some of them are confiscated for other reasons, like driving with a BAC above 0.2%.
