    This is true, but also not a huge deal for this design. Store it upright and water isn’t contacting the print. While in use there’s not much prolonged contact, or even contact area, between the water and the print.

    These weren’t absolutely leak free, but they didn’t leak any more than the injection molded pices for 2L bottles.

    For this particular project, finding a model that already had the threads in it.

    More broadly, threads usually follow one of a handful of standards. It’s just a matter of figuring out which standard is being used and then finding the size. I haven’t found a great way of approaching that for bigger threads, beyond measure with a pair of calipers, but if you’re working on nuts and bolts a metal fixture with various threads is the way to go IMO.

    Sorry to burst your bubble but these have been a thing since at least the 90s

    Oh, I know. I was a child in this era and wanted something similar for my kids.

    I just wanted something that could attach to a more sturdy bottle as 2L soda bottles are… pretty flimsy when a kid is shaking them around to get a vortex to start.






  • Michigan has term limits. It has not worked out well. It makes lobbying way easier, since the lawmakers aren’t very effective earlier in their career. You also wind up with two casts of politians: those who want to be public servants and are forced to run for a different office to keep good on the table and those who are already well heeled. We don’t need the second category in politics.

    This is the same chart, but with the 99-99.9% slice broken out too.

    The view by share is more telling IMO:

    • The top 1% have 32.5% of the wealth. This is up from 22.8% in 1990
    • The 90-99% have 36.4% of the wealth. This is down from 38% in 1990
    • The 50-90% have 28.8% of the wealth. This is down from 35.7% in 1990
    • The fact that the bottom 50% have 2.3% of the wealth. This is down from 3.5% in 1990

    The fact that 50% of our population has a single digit share of wealth is a travisty.

    The only group growing share is the 1%. Their per capital numbers are eye-watering. The 90-99% do have about 4x the per capital wealth as the 50-90% group, but the top 1% are literally 10x that on a per capital basis. The top 0.1% are eye-watering wealthy compared to anyone else.





  • Open loop is basically “use evaporative cooling to reduce electricity use”. For example, you could spray water on your home AC condenser to boost efficiency, although home units obviously aren’t intended to be constantly wet. Cooling towers are designed to be constantly wet and their radiator structures are very different, but the concept is the same.
