"Building would cost six times more than wind and solar power firmed up with batteries, according to the independent report released on Saturday by the Clean Energy Council." Actually surprised its only six. https://reneweconomy.com.au/nuclear-option-costs-six-times-more-than-renewables-study-finds/

Speaking of, the Hubble Space Telescope sent its first image back to Earth in 1990.

Folks knew right away that something was wrong with the optics, but the problem was eventually corrected.

@mcnees I knew one of the engineers at Kodak whose group built the backup mirror. He's still smug that their mirror didn't have this problem (I still don't understand how it was missed in the prep work, as it's not like they couldn't swap it out).

@mcnees Benjamin Snavely (now deceased) was the one who told me about it. You used to be able to see the spare mirror at the Air & Space museum. The Kodak group were a tad annoyed it wasn't their's going up.

UK government planning nuclear site in Scotland

https://www.bbc.co.uk/news/articles/c9eze1dzy5no

This is pointless: Scotland is already self-sufficient on renewables. What we need is a new grid interconnect between Scotland and England so we can export our surplus energy to the south!

It's all about the lobbyists, of course:

"Its ambitions for up to a quarter of all electricity to come from nuclear power by 2050 are being led by government-backed body Great British Nuclear." (Who?)

@cstross although Scottish & Southern Electricity, which I bought shares in 20+ years ago because nearly all their power was generated by renewables, built a lot of natural gas power stations in recent years (a huge mistake but on brand for the market unfortunately).

Food insecurity is “off the scales” in universities, say researchers.

Even though the Navier–Stokes equations are deterministic, it seems that you cannot make predictions beyond a fixed time horizon, no matter how small the initial uncertainty.

"Reporting that Trump is a racist fanatic who would turn a democratic government into his personal fiefdom is not crusading, it’s journalism."
