Another big factor is that every plant is effectively a completely custom design. Because of how few nuclear plants are constructed, every new one tends to incorporate technological advancements to enhance safety or efficiency. The design also has to be adapted to the local climate and land layout. This makes every single plant effectively one of a kind.

It also tends to be built by different contractors, involving different vendors and electric utilities every time. Other countries have done better here (e.g. China and France) mostly due to comprehensive government planning: plopping down lots of reactors of the same design, done by the same engineers. Although these countries are not fully escaping cost increases either.

You are completely correct that regulation is also a big factor. Quality assurance and documentation requirements are enormously onerous. This article does a pretty decent job explaining the difficulties.

I think it’s more so that the kind of people contributing to these projects are on balance not that interested in doing the marketing work.

Usually when code dumps like these happen they don’t include any of the art assets. That’s why you still need to get the game on steam to run it, to download the sprites and what not. Has nothing to do with the code enforcing anything.

I don’t know about these particular releases though, I could be wrong.

VAT is a universal tax on goods. A tariff is basically a tax that applies only to imported goods. So a tariff distorts the market, making imports from a region more expensive relative to other regions, or domestic goods.

Note that basically any tax is bad from an economic perspective. However for the government to function revenues must be raised. It is considered better for market efficiency to raise revenues in such a way as to least distort the market. Tariffs are a very distorting instrument, VAT is generally considered less distorting because it affects all parts of the market equally.

Are we painting Stalin as a good guy here? He only fought Germany because they tried to invade. Before that he repeatedly made attempts to court Nazi Germany. He signed a nonaggression pact, made an agreement to secretly divide Eastern Europe together, and continued trading. Stalin didn’t really give a shit about the fascism part, he only cared once his own territory and sphere of influence were threatened. Same as all the other major allies, btw. Everyone tried appeasement first, nobody really cared about the fascism.

“Saving Europe from Hitler” paints it as a selfless act of heroism when really everyone was mostly concerned with maintaining their own power.

is the energy used to heat the solvent creates more CO2 than the CO2 it captured?

Ah yeah, no absolutely not. In total it takes much more energy to capture the CO2 than was generated by burning the fossil fuel that emitted it.

What about algae or moss? They can be more space efficient than trees, and we can technically build a structure vertically.

I’m not too familiar with algea/moss CO2 absorption, but it could be better. Usually the downside of a vertical structure is you increase the capital investment again, negating the advantage of plants. And to provide lighting you’ll need energy which takes space as well (e.g. solar panel field)

A typical process passes ambient air over some liquid or solid solvent that can absorb CO2, then later inserts energy to separate the CO2 again for storage. For example, sodium hydroxide reacts with CO2 in the air to form sodium carbonate. Then later, the sodium carbonate is heated to release pure CO2, regenerating the sodium hydroxide in the process.

This doesn’t violate any laws of thermodynamics because of the constant energy required. Compared to growing trees, direct air capture is generally much more expensive, requiring large capital investment and constant energy input. It is more space efficient though.
