Certainly a part, a potential.

I wonder about coupling such with things like mycelia too, that can grow from radiant energy besides light, and can form symbiotic relationships with plants, and so, maybe (if this isn't too simple-thinking), yeast with algae, there could likewise by biological catalysis, synergies, mutual boons, that even then produce other useful stuff too.

~ that also got me thinking of the various pond surface plants, and how prolifically efficient growers they are too. Not sure how to put that to use, besides, idk, a source of protein and b12 for vegans.

~ and, not quite sure why, but that moonpool reforestation method springs to mind too. I don't know how yet, but put all these things (and more) together, and, ... good results. ;)
