I'm still keeping an eye on the RethinkX food report stuff, I think they pretty well nailed it on their solar, EV, battery and automation predictions, but I'm pretty skeptical about their food and agriculture forecasts for 2030 and 2035. However, I don't know much about the industry or details, but have a basic understanding of the processes and issues facing scaling the technology and that is where I focus. Yeast fermentation of basic proteins and lipids along with other bio compounds is being done and expanding rapidly and encompassing more products. Mammalian cell culture is hard to scale, but like with yeast fermentation better bioreactors could change that and continuous production flow ones are being developed.
However, there are other approaches to a bioreactor including one that uses LED lights to grow plankton or algae to feed fish commercially. It might be possible to genetically engineer these organisms to produce a variety of things in a system that is much easier to scale and needs lower sanitation standards. How many watts of solar powered LED lights and how much hydroponics nutrients would it take to grow a kilo of protein in one? People here have some familiarity with LED lighting plants and hydroponics.
It might be one way to scale up fish and even meat protein production by using a fresh or sea water based medium. It need not be done through the algae, but by something that eats the algae. Economics win in the end, not the nicest idea.
I ran across this machine, and they use them or will in Asia to feed fish.
Algae Production Made EasyOur
compact photobioreactors make it easy to continuously culture clean algae on-site. Routine tasks like cleaning and harvesting are automated, which makes life easier for hatchery staff, while increasing reliability and reducing operating expenses.
