Why haven’t we created machine that produce food from water and sunlight like plants?
In: Technology
We eat not only for nutrition. Food is very much a part of our culture and social behavior. This isn’t easy to change. If all that was needed was nutrition and not flavor, texture etc we can grow nutrient rich food like algae much faster and using much less land, water and pesticides. Essentially we don’t need to create a machine – nature has created a perfectly adequate biological factory.
The reason we don’t do this is most people would find eating green mush rather unexciting and the cost of trying to make that green mush something that looks and tastes good would cost a lot.
