If nuclear was an easy solution the French reactors would be running. Or as the article states. > In France, nuclear availability is currently at 24.8 GW, less than half the installed capacity of 61.4 GW due to safety checks at several r

There are some provisions for getting data out but they all rely on guaranteeing the same level of protection as GDPR does. This also runs afoul with the CLOUD act since due to that American companies can't store data inside the EU and

This is a nice read on why you likely should prefer a single threaded runtime and enable parallelism through other means. Or decide to pay the synchronization cost. https://maciej.codes/2022-06-09-local-async.html

Regarding concurrency and Go, it's truly an awful language from the view of concurrency when coming from Rust. It's a loaded footgun where you have to keep tons implicit details in your mind to get it right. https://eng

I should definitely have prefaced it with the caveat regarding availability of natural gas infrastructure. Gas is cheaper, when you have the infrastructure in place. Less developed countries does not have that luxury, and therefore choose c

But that is the thing. Pure steam turbine based power have been dead since the 80's with the advent of the combined cycle gas turbine power plants. You get pure mechanical power from the gas turbine and then a tiny steam side to harnes

Cars are the perfect source of smart consumers, you can think of a smart consumer like storage since they allow you to shift load but without having to pay the price of the round trip efficiency loss. They sit still for 22-23 hours per day

The question with fusion I never see answered is: "How do we convert the heat to electricity?" If the answer is steam then fusion is as dead as coal and nuclear. Or is there some solid state like solar or very non-complex working

You also have FoundationDB, which seems quite battle hardened with Snowflake's, Apple's and Datadog's adoption. Only provides a quite barebones Key Value interface to play around with though, so not anywhere near a drop in re

Awesome then that on-shore wind is even cheaper than solar, and exists at night. Then for some more, still less than 1/3 to 1/4 of nuclear you get off-shore wind with higher capacity factors.

Causality and determinism are different, and it honestly makes sense to have it be random to tease out bugs as early as possible. For a prime example see hash maps in Go, which is specifically non-deterministic when iterating over them to p

They're not a problem. It's simply that in countries which still allow landfills it's the most cost efficient method since fiberglass itself is very low value. You also have the trouble of that wind turbines designed 20-30 ye

Coal and nuclear have equivalent steam sides. Well, nuclear often has even more complexity with separate loops with heat exchangers to minimize contact between the reactor water and rest of the plant. CCGT turbines are a bit different in th

Now dig up all metals and other construction material used for the steam side and generators in fossil plants and make a comparison if that question is even worth to ask yourself. Also consider that we will be able to recycle the materials

That's why we should build renewables right? Then there's pretty much no waste.

That's why the alternative isn't coal or other fossil fuels - it is renewables.

It is simply economics. The anti-nuclear movement is insignificant but a very handy scapegoat. If nuclear made sense on a cost basis it would have pushed through somewhere globally. It's quite telling that not even authoritarian states

Consider your example. You have two options proven to work by prior knowledge. Either renewables or nuclear at 3-6x the cost. What do you pick? There's a statement in the previous paragraph doing most of the heavy lifting: "proven

The places with strong tidal currents have a tendency of limiting construction to ebb and high tide, in other words lot of expensive waiting around. Regarding the environment, under the sea it is quite fine compared to stationary platforms

Of course it matters. Money and people available to do the work is not infinite. Or do you disagree? Therefore we have to optimize for the most impact possible. Is spending 3x as much as off-shore wind and 6x as much as on-shore optimizing
