    data centers and supercomputing facilities, which consume voracious amounts of electricity and water Memphis is on the Mississippi. Evaporating the volume of the Mississippi at Memphis with graphics cards would be a pretty impressive feat. kagis https://snoflo.org/flow/report/tennessee/ TENNESSEE FLOW REPORT August 22 2025 Streamflow levels across Tennessee are currently 92.0% of normal, with the Mississippi River At Memphis reporting the highest discharge in the state with 354000cfs 345,000 cubic feet of water per second is a pretty substantial amount of water. EDIT: Water has a heat of vaporization of 2.23 kJ/g. 345k ft³ water is 9.7×10⁹ cm³, so 9.7×10⁹g That's about 2.2×10¹⁰kJ to vaporize it (disregarding the specific heat of water, just the heat of vaporization). 1kJ ≈ 0.28 Wh. So 6,160,000,000 Wh to vaporize the water going through in a second. 3,600 seconds in an hour. So at a flow rate of 345k ft³ that'd sink about 22 trillion watts through vaporization alone. https://www.e-education.psu.edu/egee102/node/1925 In 2024, the world wide energy consumption was about 186,000 TWhs 8760 hours in a year. So global average power usage is about 21 TW. If we put the entire world's generated electricity towards heat to vaporize the Mississippi at Memphis, it'd still fall a bit short. EDIT2: I also inadvertently transposed two digits (should be 354,000 ft³/sec rather than 345,000 ft³/sec) in transcribing the initial flow rate, so it'd fall slightly shorter.

    Ran the 20B on a Mac under LMStudio. Pretty zippy and did OK on basic coding tasks.

    Despite the offputting headline, it was a cool vid. Tl/dw: Milimeter wave generators used to heat plasma for fusion research are being adapted as drill heads for geothermal bore holes. It's in the early comercialization phases.

    Just keep in mind they are considered a crime in the US and can be located. Use with caution.

    I have been chuckling like a dork at this particular patent since such things first became searchable online, and have never found any evidence of it being manufactured and marketed at all. The "non-adhesive adherence" is illustrated in the diagrams on the patent which you can see at the link. The inventor proposes "a facing of fluffy fibrous material" to provide the filtration and the adherence; basically this thing is the softer side of a velcro strip, bent in half with the fluff facing outward so it sticks to the inside of your buttcrack to hold itself in place in front of your anus and filter your farts through it.

    This is going to be my goto example of why people need to care about data privacy. This is fucking insane. I'd fire someone for even throwing that out as a suggestion.
