  • That’s a solid critique. We can math it out more.

    So each 1.2GW reactor works out to be 17bil. Time to build still looks like 14 years, as both were started on the same time frame, and only one is fully online now, but we will give it a pass. You could argue it took 18 years, as that’s when the first proposals for the plants were formally submitted, but I only took into account financing/build time, so let’s sick with 14.

    For 17bil in nuclear, you get 1.2GW production and 1.2GW “storage” for 24hrs.

    So for 17bil in solar/battery, you get 4.8GW production, and 2.85gw storage for 4hrs. Having that huge storage in batteries is more flexible than nuclear, so you can provide that 2.85gw for 4 hr, or 1.425 for 8hrs, or 712MW for 16hrs. If we are kind to solar and say the sun is down for 12hrs out of every 24, that means the storage lines up with nuclear.

    The solar also goes up much, much faster. I don’t think a 7.5x larger solar array will take 7.5x longer to build, as it’s mostly parallel action. I would expect maybe 6 years instead of 2.

    So, worst case, instead of nuclear, for the same cost you can build solar+ battery farms that produces 4x the power, have the same steady baseline power as nuclear, that will take 1/2 as long to build.











  • Sure. It was a single stall shower room, beautifully tiled in black and enclosed with a full glass door. It had two knobs, hot and cold on the wall that had the rain head. Turning the knobs turned all of the water on everywhere.

    The rain head was on non stop, but you could adjust each wall jet like a round garden hose tip. Tighten to concentrate the spray, loosen to make it wider. Tighten all the way to turn off the jet. The wall jets could also be moved in a wide circular arc from their fixed point on the wall.

    It was all mechanical, no smart features or anything. I left all the jets on because why the fuck not.


  • My strangest shower thought came from my strangest shower.

    I worked for a small company years ago that paid for a “spa day” for its employees after completing a year long death march project. I had a mediocre massage, but afterwards I went to change I their shower room and decided to give the shower a go.

    My god. It had a 3ft square rain shower head and no less than 12 separate side jets on the walls, all adjustable. Every inch of my body was hit simultaneously with hot, pressured water. It was like wearing a suit of hot water armor, head to toe. No matter how I moved, water. It was basically a standing bath. They must have had a city water main hooked up to that shower stall, as the pressure was just ridiculous.

    I stood in there for nearly 30 minutes. It was wonderful, and also made me realize that this is how the ultra rich lived. This kind of luxury as an after thought, an expectation. For that moment of time, on someone else’s dime, I was in that world. That realization was almost as surreal as the physical experience itself.





  • This kills me, but its not as bad as the habit of new articles/print authors to switch between first and last names of the same person within a few sentences.

    They will introduce Jeff Snoms, and then refer to them has “Jeff” and “Snoms” interchangeably for no discernable reason. It gets really maddening when they are doing it with 3 or 4 people, so suddenly the story has 2x as many characters involved.



  • The drilling is limited to the making the channels for water flow. They are using maneuverable fracking drills and tools to get to the depths they need. They then inject water for use in the heating loop. This water should be used continuously, although it a unclear if it will need to be topped up.

    Some of these geothermal startups are creating “natural” cracks via drilling to circulate water, while others are using the drilling to place fixed piping. The latter is hard, more expensive and likely more efficient. The company in the article is doing the former if Im not mistaken.
