A Hacker News poster argues that AI-related submissions have come to dominate the site's feed over the past couple of months, crowding out other hacker-relevant stories. They cite two recent examples—a Lenovo solid-state cooling laptop and Brax Industries' open-source smart home devices—that received little engagement despite being technically interesting. The poster suggests YC could curate underexposed posts or add tagging so users can filter content by topic.

Scientists from Karlsruhe Institute of Technology and the University of Tsukuba built a solid-state cooling prototype that uses a shape-memory titanium-nickel film to convert heat directly into the mechanical motion needed to drive elastocaloric cooling, replacing the usual electric actuator. In tests, heating the actuator film to 86°C produced a 4.0 K temperature difference across the cooling device, and swapping in an external 130°C heat source still yielded a 2.2 K span, showing waste heat alone can power the cycle.

Rising electricity demand from AI data centers is spurring investment in solid-state power transformers, which use semiconductor switching instead of the century-old copper-coil design of conventional transformers. Unlike traditional units, which are hand-built and face multi-year delivery backlogs, solid-state versions can be mass-produced using materials like silicon carbide, making them smaller, lighter, and modular. Tech companies building AI infrastructure are especially drawn to them because they suit the direct current power setups increasingly used to run dense racks of AI chips.
