Photoreactor converts water, carbon dioxide, methane and nitrogen into greener chemicals and fuels

https://phys.org/news/2023-08-photoreactor-technology-pave-carbon-neutral-future.html

"photon-to-product conversion efficiency of the photoreactors must be at least 10%... capture photons under varying sun directions eliminating sun-tracking... cheap polymer extrusion method... hundreds of parallel microscale reaction channels... V-shaped light-capture unit... highly reflective optimize photon transport with minimal light loss... LEDs photon source, powered by PV and lithium-ion storage... can be integrated with photovoltaics"
