Pictured below is a self-sufficient mini-farm concept of a futuristic kitchen designed by Philips. Creating synergies between the fish, vegetables, plants and algae, this self sustaining biosphere can operate without electricity. The Biotoweruses only water, organic waste and the sun’s energy to power several small ecosystems connected to each other. From top to bottom, the levels contain:
Levels 1-2: hydroponic plants
Level 3: container algae
Level 4: Fish and Shrimp
Level 5: Organic waste
Optical fibers capture and redirect light to the plants during the day, while methane captured from organic waste can power lights at night.
