Algae Street Lamps?

Fellow solarpunk genre fans, have you ever seen the algae-powered lamps? They were a popular topic back in 2013 when a man named Pierre Calleja suggested using them.

During the day, the algae uses C02 and sunlight to create energy through photosynthesis, and at night the lamp uses that stored energy to light the area.

" Basically, an algae lamp can remove as much CO2 in one year as a tree would in its lifetime." — Smithsonian Magazine

Using the natural energy reserves of algae may actually limit it's lifespan, so other companies are now looking towards bioluminescent algae. These algae glow naturally, so there is no need to syphon energy from them.

As of right now, those companies are still working on ways to make the glow brighter, but if it works, their blue lights could give a power-free way to light a street while the algae is also munching on C02.

Realistically, there are problems with algae lamps, such as:

How would it work in freezing climates?

How often the glass will need cleaning (though self-cleaning glass cold be an option)?

Would it put off enough light to be comparable to actual street lights?

For a fictional Solarpunk story, however, I think someone could easily make this work.

The exquisite sharpness of the NASA/ESA Hubble Space Telescope has plucked out an underlying population of infant stars embedded in the nebula NGC 346 that are still forming from gravitationally collapsing gas clouds. They have not yet ignited their hydrogen fuel to sustain nuclear fusion. The smallest of these infant stars is only half the mass of our Sun.
