  • I think that used to be true on older cars, but with modern passenger cars emissions/fuel use for start up is about the same as 10s of idle. No clue if that’s true for these big diesel vehicles tho.

    Idling diesel is supposed to be very bad but long haul trucks are better at it because they need to keep refrigeration running. Either way, something like 2 minutes of idle is almost universally worse.




  • I understand from your comment that you’ve read too many sci-fi books to understand what a massive resource sink that would be with negligible benefit. It’s pretty basic physics.

    We’ve already got cheap transportation, look how that’s turning out for the planet. But I’m sure burning God knows how much energy to launch more junk into space will save the world.

    We’re already approaching a critical mass of private equity space trash in orbit, what’s a few more lowest-bidder megastructures? At least the ultra rich will get their life rafts while we burn.


  • Because the world has actual things in it like people, wildlife, culture and history. Space has none of those things. Unless you’re there working as a scientist to study things that can’t be studied on earth, it’s pointless.

    As of now it’s a glorified roller coaster. At its best private space travel could be Disneyland in space. At worst it’s just rich people paying to be carried up mount everest for clout but with exponentially more resources wasted.








  • A lot of this hinges on partisan officials choosing (often) black box software and private verification companies. But that’s not even the main problem.

    If your Ballot System contains source code, the source code is researched and code reviewed, and then complied by the company and the verification agency. Both checksums must match.

    It all falls apart exactly here. With digital voting, all other security is as performative as the TSA. It doesn’t even matter if either party in this step is malicious or if the source is open/closed.

    A code review can never make any guarantees. And if there is a bad actor, checksums are not bullet proof. Especially when we’re talking about state actors, who have access to supply chain attacks and unknowable cryptographic abilities.

    And all of this uncertainty extends just as far with the hardware. Even if a voter knew what a machine should have in it, they’ll never get the access to verify it themselves.

    Even checking a ballot print isn’t foolproof. In a secret ballot system there’s nothing tying a print to your actual tallied vote other than your faith in the process.

    Stealing an election isn’t as easy as one might imagine.

    Stealing an election doesn’t have to be easy, it has to be possible with a minimal circle of secrecy. And digital voting/tallying makes that possible.

    As others have said in this thread, the most important thing is the ability for any voter to understand and personally audit the process. That’s just not possible without paper ballots and simple counting.

    Kind of ironic for the meme because cod 4 did have a version of sbmm.

    Skill based matchmaking is the worst thing to happen to team based games in my memory. Theoretically it should lead to engaging games but it usually just is a mishmash of the high mmr players being high as a kite and low mmr players that got carried too far.

    Just feels like, why try if you’re guaranteed a 50% win rate no matter what? That leads to more friction between the people checking out and playing for fun and people playing to make their mmr bigger.

    It used to be fun to see your progression relative to the lobby and how you were improving over time. If it felt too easy you could give yourself a handicap with an off meta gun/strat. If it was hard it felt extra good to have the rare game as a top performer.

    And before people say “you just like stomping noobs”, I’ve been on both sides in many games. Floated top 2-3% in Rocket League and hated every minute, been a cellar dweller in some shooters and had hundreds of hours of fun.



  • Must be a reading comprehension issue, I specifically pointed to genetic [biological] fitness in that context. The definition is right there, I’m not wrong. I can reword it if you want: “my argument is explicitly not supporting eugenics”

    And still, no actual counter argument. Just responses that might as well be “I don’t like what you’re saying” followed by a short philosophical essay. What humans morally should or shouldn’t do is completely orthogonal to what humans are as biological creatures.

    If I’m misunderstanding the dozens of hours of conversations I’ve had with personal friends who professionally research animal+human evolution and behavioral neuroscience, please enlighten me. To summarize my understanding:

    • Sex is a widely researched topic, it’s mental health benefits are well established and there are dozens of studies on the physiological benefits in multiple species.
    • Neural pathways for sexual behavior have ties to drug addiction and violence.
    • Disrupting or over stimulating those pathways has very clear behavioral implications.

    All of this points to a very reasonable statement: humans are designed for a non-zero amount sex and large deviations from that can negatively impact social behavior.

    People in this thread hallucinate that as an endorsement of regressive public policy or toxic ideology. It’s possible (if you reeeeally really stretch your mind) to want more healthy sexual behavior in society without also supporting sexual enslavement.



  • Every single study shows it saving money in the long run. It’s already in use and doesn’t cause problems because professionals spend more thought and time on it than armchair internet engineers. You’re tilting at windmills.

    a good sized city would need a nuclear reactor brought online just for this.

    I mean maybe if our cities existed in Antarctica and experience 3"+ of snow per hour nearly every day year round and we insisted on keeping 40% of our city footprint as roads. How are cities currently running these systems? Somehow I haven’t heard of any of them building extra nuclear reactors or going broke?

    You realize that power use fluctuates and thermal energy storage is a dead simple, ancient technology? That the majority of snowfall happens overnight when power demand is at a minimum? You’re just waving around napkin math with no concept of how anything actually works.

    It’s usually heavy industry that’s providing that. If you don’t have a convenient heavy industry to provide that, then move on.

    So we’re just making things up now? CHP plants no longer exist? 17k water treatment plants and 4k datacenters using a combined 8-10% of all US power just vanished? Renewable power surpluses no longer need to be stored?

    There’s perfectly good plows for walking and biking paths

    Isn’t the goal in reducing car based infrastructure to cut the number of roads and make infrastructure more efficient? Instead of scaling heating costs to be smaller and more manageable you’d rather keep the fixed costs of a full vehicle fleet and the fixed damage of plowing and deicing? Your argument makes no sense at any scale.

    If you want to talk about energy waste how about starting with the kWh you spend defying basic common sense over the internet.


  • You’re really caught up on energy efficiency, civil engineering is not just thermodynamics. Energy is becoming incredibly cheap, before the current administration derailed our energy sector, we were on track to hit $0.03/kWh for utility scale renewable power by 2030. For reference, that’s about $10 to clear that city block.

    And again, systems like this and the more famous one in Holland MI are generally run on waste heat (from a power plant, wastewater treatment plant or datacenter), so that math doesn’t even apply. Looking only at energy cost leaves you tripping over dollars to save pennies.

    The real costs are and always have been infrastructure. Yes, it’s not possible to use this as a drop-in everywhere. It highly depends on the usage/wear of the road, space constraints, upfront cost of installation, maintenance, access to a heating solution, etc, etc… Even with this hydronic layout the main costs are the transmission lines, the cost to heat them is minor.

    It’s very weird to see so much resistance to this in an anti-car community, as if pedestrian and micromobility infrastructure doesn’t need snow removal too.
