“Cobalt Red”: Smartphones & Electric Cars Rely on Toxic Mineral Mined in Congo by Children
  • That doesn't make any sense to me, and it's been awhile since my biofuel class but I don't think that's true.

    The carbon in the combustion product comes from the biofuel, the biofuel comes from plants, the plants get the carbon from the air. Therfore, by definition, every gram of Co2 released by combusting a biofuel came originally from the atmosphere.

    It has to be neutral, otherwise where is the magical extra carbon coming from?

  • Every generation has some product/ingredient that they didn’t know was dangerous at the time: tobacco, lead, asbestos, etc. What is that item for this generation?
  • Ive been buying no added sugar cranberry juice (5 cal/serving so low sugar even including the natural sugars) I pour it into a massive dispenser and water it down, basically 6 parts water to 1 part juice with the intent being it make slightly fruit flavored water - it still taste like juice! I can't imagine drinking it straight, we as a society are addicted to sweetness.

  • That sounds like BS.

    I mean think about it logically, if I only eat several kg of trans fats a day I'll die of starvation? That doesn't pass the sniff test.

    "They basically sit in your liver until you die" - so if I eat 1lb of trans fats a week at the end of a year I'll be 52lbs heavier and my liver will be the size of a toddler?

    Maybe the body can't efficiently use them like it does other fats for hormone production and such but they definitely count as calories and they're definitely not just chilling anywhere in your body till you die.

  • What are some useful skills or hobbies that anyone can learn for free?
  • 🤮 Freecad is a barely functioning mess, fusion360 is a professional level cad that's free for hobbiest and infinitely more usable.

    I spend most of my day doing cad work, I can jump between Catia, NX, Solidworks, Fusion360 with no problems but Freecad is just horrible. I want to like Freecad but the simplest things are the hugest pains in the ass, it's feature set is huge but none of the features are actually polished.

  • China logs 52.2 Celsius as extreme weather rewrites records
  • I believe, and I'd have to go find the quote, but he meant/said simple. Simple =/= easy, just that there are a few things you can do that have a huge impact. Like you could bombard the polar caps and release a shit ton of Co2 and water which would thicken the atmosphere, trap some heat, and start a rain cycle. That's conceptually simple but practically hard. To keep on with Musk, he's also been quoted multiple times saying that living on Mars is gonna suck for a long long time.

    I guess in the same way climate change is conceptually simple but practically hard. Cutting out 90% of Co2 emissions pulling existing Co2 out is simple, most of the tech is already developed, it just would cost hugely insane amounts of money to do it quickly. We have direct air capture, we could build dedicated nuclear power air capture plants above existing limestone/granite deposits and pump them full. It just would cost $$$$/kg.

  • China logs 52.2 Celsius as extreme weather rewrites records
  • Even at +4c there will still be plenty of "nice" places for billionaires to fuck off to and build a nice little rich people commune. Hell, a +6c world is still the garden of eden in comparison to Mars.

    Yes there's a lot of interest in Mars right now, but it's really is just mega rich nerds. Hell, if I was mega rich, I'd make an aerospace company too, space is cool.

    The rich peppers are buying up land and building compounds in climate safe havens, like New Zealand.

  • Unless lasik has significantly changed, last I looked it lasts ~10 years and you can only do it twice, so it doesn't really make sense to do it from prepper reasons unless you think collapse is within 6 months. Otherwise, get the timing wrong and you could need another round of lasik just after the beginning of the appocolypes or worse you could need a new round but have already done two right before everything collapses.

  • What series did you rewatch most often?
  • My fiance and I needed something to put on in the background that wouldn't distract us while we worked late during a very busy week. We picked a random episode in season 2 and ended up re-watching the whole show over the course of 3 weeks.

    1. They arnt banning coal/wood fired pizza ovens.

    2. They are restricting particulate emissions not Co2 emissions. It's not a climate change thing it's an air quality thing. The pizzareias need to filter out the particulate, not get rid of their pizza ovens.

    3. Even if they were banning coal/wood fired pizza ovens it wouldn't effect pizza. Pizza ovens get up to 900f and the pizza cooks in 90 seconds. There is no time for any smoke flavor to penitrate the pizza. A natural gas or electric oven is going to yield the same result so long as they hit that 900f temp.

  • Exactly, corporation and individual behavior is predominantly emergent of the system. Theres some blame that can be passed on to the consumer or the corporation but only so much, it's not my fault I can't afford an electric car. It's not my fault installing solar panels on my house won't recoup the cost by the time I leave/sell.

    If you want people to eat less meat you need to make it worth people's while to eat less meat. You don't need to outlaw meat, you just need to make it less attractive from a financial perspective.

    If you want people to use less gas you don't need to outlaw gas cars you need to make it less attractive.

    You could write individual incentives and disincentives but a carbon tax is simple and hits at the crux of the problem. Remove beef, oil, gas, solar, wind, hydro subsidies and implement a carbon tax. Boom, meat alternatives are now cost comparable. Green energy is now handily cheaper than oil and gas. Theres also a sizable amount of conservatives who are for a carbon tax since it's a "free market" solution instead of picking winners and losers.

  • Tesla founders
  • There are a lot of reasons to dislike Musk, this is not one of them.

    When Elon came on board Tesla their business plan was to buy existing super cars and an existing electric drive train and then convert the super cars.

    This was all going to be done by hand in a workshop. They would do dozens of cars a year.

    Without Elon that's what they would be doing, he was behind the transition to building their own vehicles on their production lines and volumes comparable to normal manufacturers.

    That's why he won his lawsuit to be listed as a founder.

  • The WHO is about to declare aspartame can cause cancer
  • That's not the point I was trying to raise.

    My point was that people love to pile on anything artificial because they see it as unnatural and they claim it's cause they just want to be aware of the risks, but those same people usually don't know and don't care that things they partake of everyday are also cancer risks and much higher ones than the artificial stuff.

    My point in asking OP was because id wager (and wanted to see) they didn't know those were cancer risks and won't change their habits or they did know but hadn't changed their habits.
