sadly, no - you still need high quality silica, and advanced facilities to manufacture the photovoltaics. Imagine it like you buying coal and using coal to power your house. yes this coal is cleaner, and runs for 10-20 years, but there are not many coal plants.

this may very well be the case. I can not say for sure, my guess is that most cpus should be able to do something like 200mb/s zstd(3) uncompress, but you can try to benchmark uncompress speeds (there is also a zstd benchmark command), and if it is statistically significantly lower than your storage (use hdparam/dd to benchmark them), then it is indeed your cpu.

Other than memory speed, there is one more blocker - your cpu (ish). live usbs do not store the raw image uncompressed, they would be much larger in size. instead, the file system used (usually squashfs) is compressed (usually zstd (default level 3), but could be lz4, or xz, etc). whenever a file is loaded, it is first uncompressed, and if you have enough memory, you can try the load to ram (or memory, wording may differ) option, where, important parts of image are fist uncompressed and stored in memory, resulting in better performance. Now most cpus are fast enough to decompress, so limiting factor still is likely your storage (usb x.y standard) read speed (and if it stably runs that speed, or is thermally throttled), but if you are on a faster underlying source, it can make a difference.

Anecdotely, I use squashfs to compress most things i keep, and it is fast enough for most purposes, but i have observed that for benchmarks, especially single threaded, there is a significant difference. for geekbench 6, my singlecore score was close to 0.6 times of the actual score, when read from uncompressed, or from memory. for all core, score was nearly 0.85 times of the uncompressed/memory score. Would you realistically feel the difference, no imo. I even have a file system level compression (btrfs, zstd, level 3), and i do not feel a significant difference.

yup, from the fun they seem to be having, that may be the case

It would have been platform with wheels, (rollerskates may not have even been invented back then i suppose)

are they pulling sometging (like erecting a structural thing), or playing tug of war?

And you! you and other living things shed your skin cells, and so do all non living things which have wear and tear leave microscopic things behind (almost everything)

honestly i have no clue what is happening here. like there is a sculptor, and a priest on bottom left. there are billion flags, almost all different. and what even is happening on right (the wheel thingy)

everyone who has ever heard of pi, has either died, or will die. just thought of pi gives you a chronic illness which can not be cured

it also works for all perfect numbers (by definition non prime), and also triangle numbers (all triangle numbers greater than 3 or non prime), and also for all numbers above 42, and below 69. quite a neat property sir.
