ReGen Village, outside of Amsterdam, doesn't need a grid or food systems. It's a model for a future, fully closed-loop settlement.
If you live inside one of the houses in a new neighborhood being built in an Amsterdam suburb, your dining room might be next to an indoor vegetable garden. Outside, you'll have another seasonal garden. And down the street, almost everything you eat will be grown in high-tech vertical farms.
The neighborhood will be the first ReGen Village, a new type of community designed to be fully self-sufficient, growing its own food, making its own energy, and handling its own waste in a closed loop.
Any household waste that can be composted will feed livestock or soldier flies. The soldier flies will feed fish, and fish waste will fertilize an aquaculture system that produces fruit and vegetables for the homes. Seasonal gardens will be fertilized by waste from the livestock.
By using the most advanced methods for growing food—a combination of aeroponics, aquaponics, permaculture, food forests, and high-yield organic farming—the neighborhood will grow many times more food than a traditional farm of the same size, with fewer resources. Aquaponics, for example, can produce 10 times as much produce on the same amount of land, with 90% less water.
