  • But anyways - why is there a vacuum in the jar? To preserve the jam? Isn’t jam a preserve? Like, I thought the whole raison d’etre of jam was as a way to make fruit keep, unrefrigerated, through the winter? Why must we preserve the preserve? Quis custodiet ipsos custodes?

    this is “fucking magnets, how do they work” translated to rationalist, except that explaining magnets involves quantum mechanics and explaining jam jars involves high school physics (saturated vapor pressure vs temperature. that might be before high school). i also like how one linked explanation sits near two pieces of slop and is wrong








  • The developers claim this thing will use “net zero” water. This is while they want to take water that would normally be topping up the Great Salt Lake and use it to cool the site’s gas power plant.nbs

    gas turbines (like seen already in genai dcs) don’t need water for cooling, ccgt powerplant does, but it’s because there’s steam turbine downstream. dc itself could also use evaporative cooling. ccgt has some components with long lead time that will require more planning, footprint and construction than straight gas turbine powerplant
