The circle of light! Perpetual illumination! Let the algae do photosynthesis using their own light output as energy!
What's happening, chemically? Let's see ... it's luciferin. https://en.wikipedia.org/wiki/File:Luciferin_Light_Emission_... Isn't that CO2 being emitted on the right, there?
I think they mean the algae is in sunlight during the day and growing, producing light only at night.
