  • that has nothing to do with metric vs imperial:

    “Lumber manufacturers typically cut a tree into the various standard types of dimensional lumber very shortly after the tree is felled. At this point, the 2 x 4 is actually 2 inches x 4 inches, a 2 x 10 is actually 2 inches x 10 inches, etc. But then the newly-sawn (but soaking wet) lumber is then kiln-dried until it reaches the desired moisture level. During this process, it shrinks as the moisture in the wood is removed and the wood cells shrink. Once the drying is complete, the boards are then planed to a standard size. Hence, what started out as a 2 x 4 now measures 1 1/2 inches x 3 1/2 inches.”

  • sodium. gravity. carbon capacitors. lead acid. molten salt. air pressure. flywheel.

    there’s alllll kinds of battery storage solutions, and for grid storage just about anything other than lithium can be used because lithium is really only useful for power density applications where weight and size of the battery matters like cars and planes.

    nuclear fission is dead. fusion is the only nuclear worth talking about and that’s still years, probably decades away from being actually useful.

    so then: solar, wind, wave, hydro, geothermal, and all kinds of batteries is what we have now and can do cheaply and do everywhere and do it now.












  • i use revolution (selamectin) from the vet and it’s like a fucking flea nuke. if you’re getting it soon i wouldn’t worry about fleas getting in the house because once you use this stuff it’ll clear all of them out of the area in literally hours. fantastic stuff.

    also, don’t trust any over the counter flea sprays or treatments at stores, they all use neurotoxins that they claim is safe for cats, but some cats are more sensitive and it might cause neurological damage or even death.
