  • Nope! And most hydrogen is fossil fuel (methane) derived and horribly energy inefficient. At this point it’s green washing at best.

    Edit: adding data:
    Steam-Methane Reforming (SMR) accounts for about 95% of all hydrogen production on earth. It uses a huge amount of heat, water, and methane to produce hydrogen.

    https://en.m.wikipedia.org/wiki/File:SMR%2BWGS-1.png

    For inputs:

    • 6.2MWh of Heat
    • 2.2 tons of Methane
    • 4.9 tons of pure water

    The outputs are:

    • 6 tons of CO2
    • 1.1 tons of H2

    The overall energy in vs energy out is at most 85% efficient. https://www.sciencedirect.com/science/article/abs/pii/S0016236122001867

    Hydrolysis, the main competing method, and the one most touted by hydrogen backers, accounts for about 4% of hydrogen production.
    This method takes in only pure water and electricity, but it’s efficiency is abysmal at some 52%. In every case, a modern kinetic, thermal, or chemical battery will exceed this efficiency.

    Other methods are being looked into, but it’s thermodynamically impossible for the resulting H2 to produce more energy than it takes to create the H2. So at best today we could use H2 as a crappy battery, one that takes a lot of methane to create.





  • Never ask a man his pay, a woman her weight, or a data horder the contents of their stash.

    Jk. Mostly.

    I have a similar-ish set up to @Davel23 , I have a couple of cool use cases.

    • I seed the last 5 arch and opensuse (a few different flavors) ISOs at all times

    • I run an ArchiveBot for archive.org

    • I scan nontrivial mail (the paper kind) and store it in docspell for later OCR searches, tax purposes etc.

    • I help keep Sci-Hub healthy

    • I host several services for de-googling, including Nextcloud, Blocky, Immich, and Searxng

    • I run Navidrome, that has mostly (and hopefully will soon completely) replace Spotify for my family.

    • I run Plex (hoping to move to Jellyfin sometime, but there’s inertial resistance to that) that has completely replaced Disney streaming, Netflix streaming, etc for me and my extended family.

    • I host backups for my family and close friends with an S3 and WebDAV backup target

    I run 4x14TB, 2x8TB, 2x4TB, all from serverpartsdeals, in a ZFS RAID10 with two 1TB cache dives, so half of the spinning rust usable at ~35TB, and right now I’m at 62% utilization. I usually expand at about 85%


  • My favorite city builder in decades. A few notes.

    Pros:

    • Easy mode is relaxing and quite easy.
    • Medium mode is a fun challenge at first, eventually becoming fairly chill as you advance in skill and confidence.
    • Hard mode is always fairly hard, especially on harder maps.
    • There are many resources to manage, but none that feel burdensome.
    • The game is extremely thematic, it feels alive with charm.
    • Graphics are excellent, though sometimes graphical glitches can still be encountered.
    • The water. It’s so hard to explain to someone who hasn’t encountered this system before, but water is life in this game, and it’s both beautiful graphically, and extremely well simulated by physics. Learning to control the water, and see the shortest paths to end water scarcity with beaver engineering is an amazingly fun and unique aspect of the game.
    • Mods are well supported and the community is vibrant.

    Cons:

    • Not a ton of content. They’ve been very good about adding new mechanics (badwater, extract, etc) but there’s still just 2 races of beaver and a dozen or so maps.
    • No directed experience. In similar games I’ve enjoyed a campaign, challenge maps/scenarios, weekly challenges, a deeper progression system, just… Something to optionally set your goals. There’s nothing of the sort in the vanilla game. It’s fully open ended and there’s only one unlock outside of your progress though the resource tree in a map.

    All in all, I highly recommend it, especially at the modest asking price. If you love city builders, charming and beautiful art, thematic settings, dynamic challenge, and solution engineering, this is a fantastic game for you.

    Other games I’ve enjoyed that scratch similar itches:

    • KSP
    • Cities: Skylines (but Timberborn has been far more compelling)
    • Factorio
    • Mindustry
    • Planet Zoo (Timberborn has less of a directed experience, but is otherwise completely superior)
    • Gnomoria
    • Banished
    • Tropico series (though I view this as more casual)

    Get it and have fun is my recommendation.










  • You say “no one knows coffee better than he does”, while blatantly disagreeing with his entirely empirical points in his video on decaf, that it can be made by several processes, all of them are fairly good, and the result can be masterful?

    I live in a hockey capitol. That makes me nothing like an expert. Same for you.

    Okay, so you make brilliant decaf. That means your point in this thread is moot?

    Funny thing on that “subjectivity” is when you disagree with other people in this thread, you’ve plainly said they’re just entirely wrong.

    When someone disagrees with you, you hide behind “subjectivity”.

    I encourage you to introspect.
