  • I dated a vegetarian, and I love to cook. It was wild how little it took to break through the “meatless” thing. We didn’t last but I kept the skillset, and eat vegetarian at least a few nights of the week.

    I love being able to taste things at every stage without worry about food safety. Like if I don’t think a sauce is quite right, I can always try a bit. Once you kind of break through, meat freaks you out a bit… and I still eat meat!

    Edit: I’ll also add: giving up cheese and eggs would be hard as hell though… I get where that would be more exciting than meat.





  • I agree with the “no” assessment, but also need to drop the bit of trivia that sharks are really sensitive to electricity. There was a guy making a shark detterent belt that you hit a button and it gave a small zap. Guy would cover himself in food, have the shark barreling right at him, hit the button and it does a 180.

    That being said, it probably was really low current but high voltage (like a static shock), I don’t know if sharks care about a low voltage battery stack.

    (bonus fun fact: that sensitivity is why hammerhead are the way they are. With those sensors further apart you get more spatial resolution, like a radar array. It’s also why they wag there head over the floor; they’re sweeping for electrical signals of their prey)


  • I’m just going to give a quick overview of what wastewater treatment is and does.

    The basic idea is that you can have something like a can of 7-up, it looks clean, but would kill a fish dead. It’s got loads of dissolved sugar, and if you dumped it into a river, microbes would go nots on the sugar, sucking out all the oxygen as they grew, and causing a boatload of other problems.

    But you can’t filter dissolved sugar. I mean you can but it requires a highly specialized filter that would imeaditley foul is wastewater. And we’re not just talking dissolved sugar, there’s a whole range of everything in there.

    So we do something very simple: we let the 7up grow moldy. 7 up would go through a coffee filter, but mold wouldnt. We let the mold suck up the sugar, then seperate that.

    In reality it’s a bit different but that’s the idea. We grow a ton of microbes, let them suck everything out, then move them to another tank where they all stick together and settle to the bottom. The result is that the liquid at the top of the tank is clear, and free of anything dissolved as the bugs ate it all. (how we then get rid of all of that bug mass is whole other thing but basically we squeeze all the water out we can and it becomes dirt).

    The problem with stuff like pfoas or any other micropollutant is that the bugs aren’t that interested. And they’re at such a low concentration it’s incredibly hard to get such a small amount out of millions of gallons every day.

    Wastewater treatment was meant to mimic natural ecology so that when it was discharged we didn’t overwhelm the environment. If you poop in the woods, it’s probably not a problem. If everyone poops in the same area of the woods… The woods are going to look different and not in a good way. We solved that problem, but not the one of what to do when the poop is “radioactive”.

    One last note: what I described above is secondary settling (letting the bugs settle and taking the liquid off the top). There ARE filters to seperate the bugs from the liquid, but they are no where near selective enough for specific compounds. Again, think coffee strainer.


  • Bare with me here because I am not an expert. I think what they’re getting is the same as how gravity doesn’t exist. Vsauce did a great video on that, but the general notion is that because space time is curved, objects traveling in streight lines will appear to be drawn closer to one another. “Gravity” isn’t fundamental, warping spacetime is. Nothing changed but our understanding of it, which does matter for some more complicated areas.

    I think this is similar. Just like gravity “doesn’t exisit”, it’s just an emergent phenomenon: they’re saying so is time. They’re saying time isn’t fundemental, except that it’s an expected phenomenon that would arise from other factors, those factors being proposed to be some entanglement crap I have zero ability to talk about.

    And I’m putting some words in their mouth with “time isn’t fundemental”. What they’re really doing is proposing a new definition that better fits observed phenomenon/models.

    And still, none of this explains why we still have daylights savings time.



  • OK, I’m going to save you time because I do some controls and totally get how “easy” demand management should be given how simple most devices are.

    But WHAT?! Thats all built into the grid over there??? That’s AWESOME. Let me see if I have this right: there’s essentially a small transient frequency modulation in the 60hz(?) in the grid that allows devices to receive a “off” signal?

    I could be wrong but I’m 90% sure we’ve got nothing like that in the states. MAYBE there’s something like that for communicating with the meter itself but certainly not past the meter.







  • I mean… I don’t know if you’re an NFL fan or not but his stock isntly exactly high right now lol. He played like three snaps all season last season, is old for the game (for anyone not named “Tom Brady” anyway), and is wayyyy to much of a liability (and just to damn weird even if the crap he spouts WASNT dangerous) to do any kind of announcing or commenting.

    Hes crap in the locker room, having barley talked to Zach Wilson, the kid he left to play his whole season on a doomed team (I guess Zach does owe him a bit though, I really disliked the kid now I give him some respect for stepping aside then stepping up best he could). His career won’t be affected because random crap like this IS his career now. The jets have a contract, but there is no way Rodgers plays any meaningful football anymore.
