A 45' by 45' biosphere home that produces most of the daily food needs for four people. A biosphere home includes a large fish tank supplying fish for food, as well as hydroponics located through the home.
Solar energy is used to supply heating, energy and water heating.
A biosphere home supplies food for a family of four. The fish tank water is used as nutrient water for the hydroponics throughout the house. If there are no fish in the tank inorganic nutrient can be added to the water. The fish tank can be used as a large home aquarium, where the pond biosphere is enjoyed as a hobby and no food is used from the pond. The fish pond is a very effective heat storage unit that stores solar energy during the day, keeping the home cool, and releasing the energy at night, keeping the home warm.
