  • Yes, 3mf files have all the tweaks ready, but it’s always a good idea to double check. Let me know on printables if you have any issues.

    90% infill would be a lot of plastic. Much more expensive than the plaster, but you do you. For info, the finished base with the plaster weights something like 350g and it’s a similar weight to the shade. PrusaSlicer give an estimate of the material use after slicing. I would recommend to do it only if the base would be at least 300g otherwise the lamp might not be very stable. Maybe you can optimize things by having 100% infill for a portion at the bottom (top of the model) and a 5% infill for the rest, to make the center of mass as low as possible.









  • This device attaches to a car’s tailpipe, capturing heat and converting it into usable electricity. The researchers’ innovative system includes a semiconductor made of bismuth-telluride and uses heat exchangers—similar to those found in air conditioners—to capture heat from vehicle exhaust pipelines efficiently.

    Basically, slap Peltier modules on the exhaust pipe. This ain’t gonna do much. We can invent a thousand applications for Peltier modules, until there is a massive technology breakthrough in terms of semi-condutor materials, it’s kinda pointless.

    Reusing heat energy from exhaust is what turbos are doing for 120 years now.
