'10,000 times faster than a human scientist' — New AI tool designed ultra-efficient heat-to-electricity generators at lightning speed, a breakthrough that could slash the cost of energy harvesters and help enable cheaper, high-performance home heat pumps
Researchers in Japan have developed an AI tool called TEGNet that designs thermoelectric generators much faster than traditional methods. The tool achieves over 99% accuracy while using only a fraction of the computing time required by conventional solvers. This advancement could lead to cheaper and more efficient energy harvesters and home heat pumps.
- ▪TEGNet was developed by Takao Mori and colleagues at Japan’s National Institute for Materials Science and the University of Tsukuba.
- ▪The AI tool reduces simulation time from thousands of seconds to fractions of a second while maintaining high accuracy.
- ▪Thermoelectric generators convert heat differences into electricity without moving parts, making them useful for spacecraft and remote sensors.
- ▪TEGNet's performance prediction accuracy exceeds 99% while using just 0.01% of the computing resources of standard solvers.
- ▪The breakthrough could lower the cost of waste-heat recovery systems, though manufacturing scalability remains to be proven.
