I actually thought I already posted about this bad boy which unfortunately is only a design concept from Philips. For those that are not familiar:
Aquaponics /ËˆÃ¦kwÉ™ËˆpÉ’nÉ¨ks/ is the symbiotic cultivation of plants and aquatic animals in a recirculating environment.
Aquatic animal effluent (for example fish waste) accumulates in water as a by-product of keeping them in a closed system or tank (for example a recirculating aquaculture system). The effluent-rich water becomes high in plant nutrients but this is correspondingly toxic to the aquatic animal.
This system is called the BioTower, the first 2 levels are hydroponic plants with the third being algae. The fourth layer contains shrimp and fish which produce organic waste which is stored in the bottom layer.
The lights are powered using optical fibers from the sun and the methane from the organic waste powers the lights at night. The plants and seafood can then be consumed all powered by the various ecosystems.
I couldn’t even imagine what something like this would cost if it came out of the design phase, though a simple cover over the organic waste and this would make a great conversation piece.
