Damn tankies again stealing solarpunk aesthetics! (/s)
for fuck sakes, no.
These have a dim glow similar to mushrooms, no one is going to light a city with that.
I don’t think there’s any fundamental reason why you couldn’t get plants to produce a stronger glow though.
Of course there is, you can’t get more energy out than you put in.
Obviously, but that doesn’t mean plants can’t be designed to accumulate energy during the day though photosynthesis and release it at night in form of bioluminescence. There’s actually a whole separate line of research regarding that:
You don’t always need a bright light, lots of cities even cut lights few hours at night (0-5 am) to preserve both energy and dark sky for biodiversity.
Some cities are already using glowing plants, but more for events, there is a start-up that provides this solution since few years
