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.
Caddy is the only reverse proxy I have ever managed to successfully make use of. I failed miserably with Nginix and Traefik.
Caddy has worked very well for me for several years now. It gets the SSL certificate from my domain name provider and all.
