It's LED lights and food. How fascinating is this microalgae?

According to Lei Feng, microalgae are a kind of autotrophic plants which are widely distributed in land and sea, with rich nutrition and high photosynthetic capacity. It is a renewable biomass energy source and an effective way to reduce carbon dioxide through photosynthesis. Earlier researchers found that microalgae produce weak currents when they are photosynthetic. A small amount of microalgae is enclosed in a sealed glass container to collect the LED light that lights the bottle.

The Museum of Contemporary Art in Pittsburgh in the emergence of such a peculiar exhibits, called "bio (Living Things)". It is the architectural designer Jacob Douenias and industrial designer Ethan Frier, the use of micro algae in Spirulina specific nature, ingenuity designed a concept of microbial photosynthesis lamp.

Spirulina is chosen because of its unique green color, coupled with the absorption of light, and its edible (can be made into powder, added to the food). Two designers will use special Spirulina these traits, which was kept in alkaline medium, and then into the glass like tank size, with waste heat, light, and carbon dioxide, will produce Spirulina photosynthesis, which emit green light.

These shapes are different, all kinds of hand blown glass bottles to large indoor to provide heat and light, and they are the high performance photo bioreactor to algae inside the heating, lighting, ventilation, nutrition and metabolite control.

Working principle and process

Designers will be installed in a variety of different shapes of Spirulina large glass, can be hung or placed as lighting and decoration in the living room and dining room, the light through photosynthesis, different parts of the room a refreshing green light. Find another humble place to install control systems, with water pipes and cables to connect each light. The control center controls the circulatory system of each light.

3D printed nylon piston openings are mounted on the table and the flow of the system can be controlled manually. When the liquid concentration is high enough, these 18 valves can be opened to collect spirulina, or to supply fresh cultures. The following boxes are the core of the entire supply system, consisting of pipes, pumps, pumps, LED drives, filtration systems, heaters, etc..

Such a set of waste heat and carbon dioxide microalgae photosynthesis lamp, not only can make the whole interior decoration looks fresh and natural, but also special environmental protection and energy saving. If it can be effectively developed, I believe it will make a great contribution to human society. The goal of the two designers was to get the public to pay attention to the forces of microbes and to allow the resources to be developed.
