So who will bear the financial risk? So far, it is obviously not sustainable to finance nuclear power plants from the electricity they produce. In other words, they are not even viable as a business. https://www.theguardian.com&#

Are there any known problems or difficulties with them? I guess the materials science aspect is extremely difficult as it is already a huge problem in conventional designs...

If we want to speed up the end of fossil fuels, while not increasing poverty, and not artificially distorting markets and technological developments by politically meddling with costs, we have to do these 3 things: 1. Introduce a substantia

What I also found is that Racket is a very good match to Rust, in a similar style as writing Python and extending it with translated C code where speed is needed. The advantage is that both languages allow for a functional style and Racket

Yeah, maybe it should cite sources. Also, the title of that page makes it clear that the topic is prioritization, which, funnily, gives a lot more focus to the text.

That diffusion isn't efficient is not surprising as it's an almost purely entropy-generating process. But does centrifuge enrichment not use still, in absolute terms, a large amount of energy? Looking at the EROEI numbers of diffe

Also, hydrogen can be mixed into natural gas, without changing much infrastructure. This is of course only a transitional measure, not an end goal, but doable now and a very cheap one.

Similarly as in Chernobyl, the chain reaction produced excess heat, and this likely caused water to dissociate into oxygen/hdydrogenium which caused the big explosion. In that sense, it was not a nuclear explosion, but one caused by an

Actually, the economics of nuclear and wind and solar energy is quite similar in one important aspect: You have a huge upfront cost for building the plant, and then when it is running, relatively little, or very little cost for generating a
