Not my videos, just recommending here, good watch. Not really IT, just a lot of stuck valves and old school marine engineering. Creaking sounds when they try to bosh the stuck parts back open. More videos on same topics on the channel, worth watching. Newest one deals with electical systems.
Not sure if Diamond Geezer is reading this forum, he may be, some of his blog posts get reposted in here and sometimes mentions extra 100k views.

Article is a bit old or the prices got a lot higher in last couple of months.
Just had a look at my recent electricity bill.
35 UK pence per kWh
that will be like 43 US cents at current rate. (not 27 like on the list)
Not sure what it costs in Germany at the moment but that is well above 39 cents making Germany on top the list.
Walk. Free, enjoy some tunes in your headphones, explore the area, stop for a beer when you feel tired.
I`m in London UK and I walk a lot. Doing callouts in central, sometimes rather than taking public transport home I will walk back . Finish work at 5pm, walk 20 kilometers home be back at midnight.
Unfortunately it’s prohibitively expensive for larger “intricate” work projects. Otherwise it’s good stuff. Just a little more expensive than I’d like per linear meter.
I been watching one youtuber and his streams playing The Witcher 3 game.
He has to censor the moments when he fights with certain beast, an Water Hag/Baba Wodna monstrosity. .
Evil creature has a woman-like breast on display and hes seriously worried about getting demonetised by youtube for that....
I miss good mp3 player days. I started on iriver cd player that could read MP3s... once i had some spare money upgraded to iriver H10 wit 20GB spinning rust drive (still have it, still working, sitting in the drawer).
Once tried an old ipod, to see what the hassle, learned the pain of loading my own music to it, and the lack of file browser on it, no i dont want that artist/album BS, got my own categorized collection. Sold that one quickly.
Sandisk sansa with rockbox was spot on, both both units failed like a year from time i bought them.
Currently using an old old heavy duty samsung xcover2, with cyanogen mod, it does not have a simcard just 128gb microsd with lots of music on it. DAC is reasonably good on it and it plays FLAC no problem.
Doubles as offline GPS with osmAnd maps loaded in.
There wont be much left on the other end because of volt drop in cables. But can be possible to make it into a HVDC transmission line. Will add bit of weight on the starship.
You definitely need HV. At 100kV and 10A, the lost power if you send 1MW is around 60kW: a fairly serviceable 6% or 20W/km. However, your losses at a fixed voltage scale quadratically with your power draw: you'd lose 24% of 2MW.
If you sent it at 1000V, the I²R losses to send 1000A over that cable outweigh the transmitted power by 600 to 1 and your cable is burning 200kW per kilometre. Which in a vacuum would probably just melt it in fairly short order.
Which is why the bigger HVDC links get, the higher the voltage: there's a 1MV+ system in China that sends 12GW over 3000km.
Also I'm not sure how lunar regolith will work with regards to the "earth" return path so you might well actually need two wires.
600Ω (WolframAlpha gave me 510, but let's go with the bigger number) isn't that bad, and you don't need anything expect bare metal to run HV on the moon because both the vacuum and the regolith are already insulators.
