Hydroponics
The growing movement of hackers and citizen engineers trained at the Floating School began to work out solutions to this problem by sourcing materials illegally from the mainland and building systems for vertical gardening, seaweed farming, and most commonly, small, mobile hydroponics systems. These last are constructed from recycled PVC, solar cells, water pumps, and rechargeable batteries. Each unit can be easily maintained by its owner, and any soil required can be obtained or produced by multiple methods including human compost, and the dredging of certain areas of the lagoon. The pumps can be run with regularity on their solar cells, with battery power available when the weather dictates.
