  • A car output is going to be ~12-14Vdc and the solar panel at 24V. You do not want to connect those two together. Ideally you have some kind of switch that connects the input to the bluetti only to the solar panel or only to the car outlet, and to the car output only if it is present. You can probably use a contactor or a heavy duty relay that is 12V and connect the NC contact to the panels, NO to the car, and COM to the bluetti. Add a capacitor to dampen spikes whenever the system switches and connect the grounds together. A bjt jank, and also have to check the relay ratings / coil power usage



  • Coal plant burns coal to heat water, makes steam, and the steam powers a turbine to produce electricity. A nuclear power plant uses nuclear fuel to heat water and produce steam similar to a coal plant. It may do this indirectly (e.g. second loop between the nuclear fuel and water loop to prevent the water becoming radioactive). This means that to build a nuclear plant you essentially need to build a coal plant, and then also the nuclear reactor and safety stuff, which makes them more expensive. Since coal plants are being turned off anyways, it might be more cost effective to just retrofit old coal plants so the only cost is the nuclear reactor side of things (plus any necessary maintenance and upgrades)


  • Also if you want a domain but dont care about the actual address, a .xyz domain composed entirely of numbers with less than 10 digits is $1-2 + same as renewal fee per year. $1.22 for me on porkbun

    Just be sure to redact the whois information bc you will get a call from scammers trying to get you to register your domain on some “internet map” for a small fee acting as if its some step in your setup process you havent done yet

    Behavior is called mobbing

    Its not worth it for the predator animal to go after a bunch of smaller birds that are harassing it so they tend to leave. Its also done to steal the predators meal when they leave or to distract it while another bird steals its food. Also draws attention to them to prevent them going stealth, which can affect bjrds like owls, who tend to be victim to this type of attack from prey birds. This makes them leave because their main weapon is stealth and when their cover is blown, they will have a harder tome catching prey (including the mobbing birds’ babies)





  • Paint used for the images on the side of the glass had heavy metals (e.g. cadmium). As the paint flaked it became possible to ingest it. A mom who for some reason had an XRF gun (x-ray fluorescence, allows identifying element makeup of things. Useful for identifying material or ore content) and saw a ton of cadmium then went and reported it







  • Just searched my old user names and found absolutely nothing except for one post from 2012 on Minecraft forums

    It’s one part a lack of SEO/searchability and nine parts sites that are dead and gone taking that information with them.

    I haven’t been the best about backups, passwords, etc but I’ll probably set up a dead mans switch at some point to release my passwords to my family and delete my drives if/when I can’t do it myself. I’ve already got bro on call to drive to my house and shred the drives •=•
