Thought you guys might enjoy this:

This is an interesting development project in Indonesia. One feature of the "Village Hub" described in the video is an algae farm fed by CO2 siphoned off from ethanol fermentation. I've heard of greenhouses using CO2 from breweries, but this is the first aquatic use I've ever heard of outside of the hobby.

What do you guys think?

Also, on the topic of efficiency (which is a reoccurring theme in the video), does anyone else here besides me distill their DIY CO2 reactor slurry after it's done producing CO2?
