I love this... and a idea for scaling is to go vertical. Think 20 story on the side of a buildings. The bottom two stories is the fish tanks. top 18 are on conveyers slowly rotations of trays on lifts and belts. they then can be harvested at ground level to be placed in trucks but get to use natural sunlight when at top while using lights on bottom. They can move as slow as 1 mile per hour.
