China tests heat-to-electrical power converter on Tiangong space station

Two Shenzhou 15 astronauts work outside the nation's Tiangong space station on April 15, 2023, as seen by a camera on a space station robotic arm.

Astronauts aboard China's Tiangong space station have been testing out ways to convert heat into electrical power.

A Stirling power converter developed by the Lanzhou Institute of Physics of China Academy of Space Technology was installed in a specialized equipment cabinet for basic tests in the Mengtian lab module of Tiangong, according to CGTN.
