YOU DONāT UNDERSTAND. This is ingenious.
The design is a light bulb surrounded by a glass casing. The glass is filled with (water based) media and microalgae. The top is permeable to gasses so that gas exchange can occur. All of the wiring is linked to the grid underground.
Since the light source is inside, it gets scattered and ādimmedā by the water and algae. This makes it less glaringly bright and scatters the light wider, which is good for a street light. It is not longer white light as well, which helps make it easier on the eyes while still providing light.
At the same time, it provides the light for photosynthesis in the algae, so they are continuously exchanging CO2 for O2, not just in the day. It also provides a source of heat, which helps keep the algae from going dormant during cold weather (as in the snowy picture above).
And notice how I did not specify permeability - thatās because NOxās (NO and NO2) are also permeable and can be used as nitrogen sources to microalgae. In fact, algae are relatively low maintenance. As autotrophs, they donāt require super complex media, not does it really need to be changed/added to. (Iām actually fairly certain that there would still be algae in these tanks a year later; it may need to be cleaned or something, but there would be some living algae.)
