  • 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.







  • Fedora is a very solid, no nonsense distro. It gives you a vanilla Linux experience, with sane defaults out of the box. You get major updates every 6 month shipping newer version of the core stuff (kernel, desktop environment, etc). The Fedora community is dedicated to deliver a reliable OS and tests a lot before shipping updates.

    It’s my favorite desktop/laptop distro for many years.

    However, there are a couple a pitfalls to avoid. If you go for it, follow some beginners guide to get you sorted out with things like codecs and proprietary drivers. E.g: Things to do after installing Fedora 40 - itsfoss.com I would definitely recommend to do steps 2, 3, 4 and 5 from this guide.
