Shame the cloudflare VPN wall doesnt let me sign it. It just loops a captcha at me that insta-fails.

Absolutely this, sedans are virtually dead here in America thanks to CAFE regulations and I staunchly refuse to buy an SUV or pickup, even used, unless I have a need for something bigger, and then Station Wagons and vans will get my attention before pickups, and SUVs will never get my attention.

Especially when you consider my 2000 Town Car (RIP Mercury) got 21MPG city and 30 Highway (on long interstate trips), even though it was only rated for 16 city 23 highway, but somehow a 2025 Ford Explorer only is rated for 18 city/25 highway, only 2 MPG better than a 25 year old car’s official rating on both categories, despite being the same price new, before being adjusted for inflation (both started between $39-40k), 25 years of development for a 2.3L I4 SUV to match a 25 year old 4.6L V8 sedan, our vehicle market is a joke.

By my understanding fuel cells are less about form factor, and more about directly converting the fuel into electricity across a membrane, like how batteries operate, so like a battery that takes in Hydrogen on one terminal and Oxygen on the other, being more efficient than burning it in an engine and trying to recapture some of that as electricity after thermal and friction losses have eaten into it.

So it is more a replacement for the engine than it is for the fuel tank. Wikipedia

Oh, didnt know that was posted, some of the tests seem to be different from last time, it hasnt regressed but hasnt improved much yet either (from the ones that were the same). It does seem to have pulled ahead of BTRFS since the last test, doubling score in the DBench test, but it still varies a lot compared to the other filesystems it seems, doing worse pretty regularly.

That’s fair, it has changed a bit since then and I’m hoping we get another filesystem benchmark to see if it has improved, and the caching features might offset that on frequently used data, but I don’t know how hard that would be to benchmark.

In my use it has been pretty stable so far with 7 disks participating (3 caching SSDs, 4 mechanical disks, with 3 copies of metadata and 2 of data), but I’m not using the more experimental features like erasure coding, I will note the on-disk-format has changed twice since it has been in the kernel, and it hasnt been there long, but it has succeeded both on-disk-format upgrades without obvious data loss, and it recently got self healing for some checksum errors, Id say its probably ready for use if the data is backed up, replaceable, or can be gone without (so for me games are all I have that fits this). Otherwise I would use caution if you use it, but I am very optimistic about the future of the FS, as Kent Overstreet (the creator) has taken a lot of care with it.

I use bcachefs for my games, I like that it lets me havemultiple disks with redundant data copies, plus ssd caching of frequently accessed files, this fs is linux specific for now as far as I know, and is still experimental. I use ext4 for everything else, and FAT32 for flash drives.

The metals are forming a Galvanic cell with the salt water as an electrolyte, the section of the linked article labeled Galvanic corrosion mentions the splitting off of hydrogen in salt water. There is no membrane so electricity just goes through the conductive salt water. The exact voltage depends on which two metals were involved, this page has a table of the voltages in sea water (in mV)
