  • I’m not a rabid anti-nuclear, but there are somethings that are often left out of the pricing. One is the exorbitant price of storage of spent fuel although I seem to remember that there is some nuclear tech that can use nuclear waste as at least part of it’s fuel (Molten salt? Pebble? maybe an expert can chime in). There is also the human greed factor. Fukushima happened because they built the walls to the highest recorded tsunami in the area, to save on concrete. A lot of civil engineering projects have a 150% overprovision over the worst case calculations. Fukushima? just for the worst case recorded, moronic corporate greed. The human factor tends to be the biggest danger here.
















  • I hate Musk and his personal everything, but Like SpaceX. However, when people gush about reusability, they seem to forget the 135 Space Shuttle missions (2 fatal failures , yes.). All done with 5 vehicles. Yes expensive etc, but truly amazing.

    Also, I really don’t find anything SpaceX is doing revolutionary. Impressive? Yes, but it’s essentially incremental engineering, made possible by ginormous funding, including NASA money, and a private company doing things that NASA can-t politically afford.

    Imagine NASA crashing 4 Shuttles before getting landing right. There’d be no NASA by now.






  • I have a modern stovetop stainless steel pressure cooker, very common type in Europe. It has three redundant pressure / over pressure relief safety sytems plus a very hard to circumvent locking mechanism that only unlocks at ambient pressure. Instant pot types look interesting, because they expand on the concept, but a major drawback I see is that they are often small (my pressure cooker is 6L) and, basically a dealbreaker for me, the vessel is usually plastic coated, I.e. non/stick. I think I will stick with mine, which coupled with a programmable stovetop induction single heater I own, fulfills part of the features.
