AI slashes the time needed to design better heat-harvesting devices

Phys · · 614 words · By Sam Jarman

Researchers at the National Institute for Materials Science in Japan have developed an AI tool called TEGNet to optimize the design of thermoelectric generators. The tool significantly reduces the computational time required to predict device performance while maintaining high accuracy, potentially accelerating the development of waste-heat recovery technology.

“cutting computational time by around 10,000-fold”
CORROBORATED
Two independent sources confirm the computational time reduction. One explicitly mentions a '10,000-fold' reduction, and another specifies it uses '0.01% of the computational time' (which is a 10,000-fold decrease).

“this approach allowed the model to learn the underlying physics, resulting in a system that could make a single performance prediction in just a few milliseconds, rather than tens of minutes”
VERIFIED
A web search result provides specific timing data: a typical simulation took 2,237 seconds (approx. 37 minutes) in COMSOL, while TEGNet produced the result in 0.25 seconds (250 milliseconds), directly supporting the 'milliseconds vs tens of minutes' claim.
