It has been a science fiction dream: the completely integrated, closed loop system “micro-farm.” And we get it with the Inka Curve, a vertical minifarm that provides herbs, grasses, fruits or vegetables grown on a vertical “bio-quilt.”
But these need nutrients, which come from fish poop. But fish tanks need cleaning and aerating, and the vertical farm needs pumped water which requires power; that comes from wind turbines and solar panels, stored in a battery bank.
So the fish poop provides nutrients for the garden, all powered by the sun, using 10% of the water of conventional farming. The bacteria in the bioquilt of the vertical farm break down the nutrients and purify the water so that it can be returned to the fish tank, providing a balanced diet of protein and green vegetables on an incredibly small footprint. It is a dream kitchen addition that means we will never have to go out food shopping again.
