LillyBot 2.0


LillyBot 2.0 is an automated device to cultivate edible micro-algae (Spirulina) in a domestic environment. A personal micro-algae farm is an environmentally friendly way to produce and consume a complete nutritional source that grows at the highest rates through photosynthesis, fixing CO2 and producing O2.

LillyBot 2.0 is composed of an acrylic frame that contains the microalgae solution tank, the hydraulic and the electronic control systems, and a growing chamber based on the WaterLilly 2.0 system.

Spirulina is considered a healthy food that contains all of the amino acids, omega 3 and is a complete protein. Its growing rates are very fast because, like all photosynthetic monocellular organisms and unlike more complex green organisms, close to 100% of its cells participate in the growing process. The Spirulina grows in a specific water medium composed by non-chlorinated water along with other nutrients (Sodium Bicarbonate, Ammonium Phosphate, Sea Salt, Potassium Nitrate). The most important of those is the Sodium Bicarbonate that creates an environments that resembles the ash lakes in nature in which Spirulina grows.

The LillyBot series is a number of prototypes that create the perfect environment for Spirulina to grow providing an optimized light exposure, an efficient natural aerating system and CO2 feeding, and an efficient agitating system that avoids the formation of algae deposit. She’s composed by a clear acrylic tank and frame, a submersible water pump, a clear piping system, a clear growing chamber (that can consist in a plastic bag or in recycled plastic bottles), and a removable aluminized Mylar foil. Lilly-bot can be equipped with a termometer and automatic EC and PH meters to keep the solution properties under control and add nutrients when required. The first prototype of this series, Lilly_bot 1.0, has been presented at the Dutch Design Week 2013 in Eindhoven.
