Researchers are developing new technologies to improve energy efficiency through advanced thermal management and solar integration.

Initial developments from the Karlsruhe Institute of Technology (KIT) and the University of Tsukuba involve a system that converts waste heat into cooling without electricity consumption. This method uses nickel-titanium shape-memory alloy sheets to transform thermal energy from sources like car engines or solar radiation into mechanical movement and refrigeration.

Subsequent research at KIT has expanded into hybrid solar systems. This technology integrates photovoltaics, solar thermal technology, and passive daytime radiative cooling (PDRC) into a single surface. By using a transparent emitter to release heat as infrared radiation, the system can simultaneously provide electricity, heating, and cooling, offering potential applications for energy-intensive sectors like AI data centers.
