Gold Nuggets Can Be Formed With Electricity, Scientists Claim
  • Very true. Unfortunately, this process just pulls gold from dilute sources and gathers it into nuggets, from small ones to very very large. No gold is being made new though, that would be great.

    Gold Nuggets Can Be Formed With Electricity, Scientists Claim
  • Well, that is the amount gold that is mined or recycled every year that is used in electronics. The thing is though, a lot of the gold used in electronics is never recovered. So a considerable amount of the gold used in electronics is removed from from circulation in a way the gold in jewelry or bullion or coins isn't. It isn't the primary driver of gold's price increase, but it is a significant factor.

    Gold Nuggets Can Be Formed With Electricity, Scientists Claim
  • Gold prices have risen steadily for a long time, partly because of its use in electronics. Over $2500/ounce now. But another quirk of gold is the ease with which we can make very thin coatings of it over other materials, sometimes only a few atoms thick. So it is commonly used, but in very very small amounts per device.

    Who Wants To Be A Lemming
  • The first change needs to be teams pay for their own stadiums instead of them being taxpayer funded from cites and states. I don't care if it will drive tourism, use that money to take care of the purple in the city and make the city a nice place, even make it a nice place for a stadium, but make the team owners/pro leagues pay for their own damn stadium.

    An inmate’s body temp was 107.5 when he died. The state of Texas says heat did not kill him.
  • Metric measuring systems are superior in almost every use case, with the exception, I think, of how temperature feels to us. As arbitrary as Fahrenheit seems, it does seem like a more natural scale to talk about the weather or body temp. The smaller units are nice for these purposes too. 0 being very cold and 100 being very hot feels less arbitrary than -18 and 38, even if celcius is more logical and easier to use for many other things.

  • At some point it almost stops seeming like greed and more like the willful extinction of the human race. But I'm probably just underestimating the greed.

    Biden’s Record Is Full of Climate Wins — So Why Don’t Voters Know It? Environmental groups are making a concerted effort to educate voters about President Joe Biden’s climate policies before election
  • Sure he's got climate wins, but some of the wins are questionable, like giant hydrogen hubs. Hydrogen sounds great on the surface, but the more you dig into it, the more issues crop up. Some of these hubs will end up producing hydrogen by burning fossil fuels, and that isn't a win at all. And speaking of not winning, we are producing more oil and natural gas than ever before. That's why we aren't excited about his "Climate Wins", they are offset if not overcome by losses.

    Having said that, regarding the Climate, pollution, and everything related, Trump is the worst choice. He's already promised Carte Blanche to oil execs if they donate to his campaign. (Not in those words of course, simpler, more incoherent ones.)

    Denver basic income reduces homelessness, food insecurity
  • And it costs municipalities less money than the problems it prevents, so obviously we shouldn't do this everywhere and raise the standard of living for everybody. Because it wouldn't be fair, somehow.

    What are the most evil media corporations in the world?
  • Sure, to get them to speak in unison. They did all read from the same script though. It wouldn't be as viscerally creepy without the editing, but I would say the situation is as bad as the video makes it seem.

    Arm strength is suddenly going down as well as right arm giving out before the other.
  • I am not medically trained in any way, but I would say sudden noticeable losses in strength and endurance in one arm is a good enough reason to make a doctors appointment. So many issues are easier to deal with when caught early, take care of yourself!

    Aptera secures capital to bring full production online, closing crowdfunding in June
  • If you are in a small car and an F350 hits you, it is going to do a lot of damage whether it is this or a more conventional car. At least with this you may limit the body and frame damage to that wheel and suspension. If it just tears off that wheel it will pobably transfer less impact to the passenger compartment too, and I care more about my neck than a wheel or quarter panel.

  • It's more like they are around again, they folded quite a while ago then started back up in 2019 I think. Still a fairly long development, but not 15 years, haha.

    It is a strange looking vehicle, but there are a lot of things I like about the company's philosophy and approach.

    Very interesting company. They started with a way to produce graphene at scale, then went looking for something to do with it. Their first idea was to use it as a cement additive. They have since used it as friction reducer in engine oil, and are selling it in Australia, Canada, and soon the US, as a radiator coating to improve HVAC performance.
