Polish researchers advance green hydrogen and infrared AR technology

Researchers in Poland have achieved two distinct scientific breakthroughs in the fields of renewable energy and optical technology.

At the University of Gdańsk, an interdisciplinary team has investigated the use of biological light sources as an alternative to conventional radiation for the photocatalytic production of green hydrogen. By studying green fluorescent protein (GFP), the luciferin-luciferase system, and bioluminescent bacteria, the researchers identified the specific conditions—such as light intensity and spectral matching—required to make biological light a viable driver for hydrogen production. While not yet practical for industrial use, the study provides a roadmap for future light-driven chemical reactions.

Separately, scientists have developed a prototype for augmented reality (AR) glasses that utilize two-photon vision to allow humans to perceive infrared pulses as visible light. Using wavelengths between 950 nm and 1100 nm, the technology enables users to see infrared signals as blue, green, or yellow colors. This advancement aims to maintain image sharpness across different planes and reduce visual distortion. The technology holds potential applications in medicine, aviation, and military sectors.
