Cool seaweed is LED bulb and food

Microalgae are a kind of autotrophic plants that are widely distributed in land and sea, rich in nutrients and high in photosynthetic utilization. It grows through photosynthesis and is an effective renewable energy source as well as an effective way to reduce carbon dioxide emissions. Earlier, researchers discovered that microalgae can produce weak currents when they are engaged in photosynthesis. By loading a certain amount of microalgae in a closed glass container, the LED lights in the lit-up bottles can be collected.

This time, a peculiar exhibit appeared in the Pittsburgh Museum of Modern Art named "Living Things." It is a conceptual microbiological photosynthesis lamp designed by architect Jacob Douenias and industrial designer Ethan Frier using the unique properties of spirulina in micro-algae.

The reason why Spirulina is used is because of the unique green and green color of spirulina, combined with the absorption of light and its edibility (it can be added into food as a powder). The two designers took special advantage of these qualities of spirulina, cultivated it in an alkaline culture solution, and put it into glassware of the same size as a fish tank. With the combination of waste heat, light, and carbon dioxide, Spirulina was Produce photosynthesis, which emits green light.

These large, hand-blown large glass bottles provide light and heat to people in the room. They are also high-performance photobioreactors that heat, emit light, breathe, supplement nutrients, and control algae inside. Metabolites.

Working principle and process

The designer attaches spirulina to a variety of different shapes of large-scale glassware, which can be hung or placed in the living room and dining room for lighting and decoration. Photosynthesis can be performed through the lights, and the different corners of the room can be refreshed and refreshed. Green light. Find a humble place to install the control system, connect each lamp with water pipe and cable. This control center controls the circulatory system of each lamp.

The 3D-printed nylon piston opening fits on the table and controls the system flow with your hands. When the liquid concentration is high enough, these 18 valves can be opened to collect spirulina, or to replenish fresh culture fluids. In the wooden box below, it is the core of the entire supply system that consists of pipes, pumps, air pumps, LED drivers, filtration systems, and heaters.

Such a microalgae photosynthesis lamp that uses waste heat and carbon dioxide can not only make the interior decoration look fresh and natural, but also special environmental protection and energy conservation. If it can be effectively developed, it is believed that it will make a tremendous contribution to human society. The purpose of the two designers' design is to let the public begin to pay attention to the power of microbes and let this resource be developed.

Disposable E-cig

More stable performance

Disposable ecig have a completely enclosed design, reducing the need for charging and replacing cartridges. The no-charge design also reduces the occurrence of faults. It is understood that with rechargeable e-cigarettes, each cartridge needs to be charged at least once and the battery efficiency is extremely low, while the design of disposable ecig can solve this problem very well.

Disposable ecig are very easy to carry on daily trips, no need for any operation in the use of airflow induction, direct suction can be out of smoke, meaning that you just need to suck directly on the hand can be the main feature of the small cigarette is practical portability is the main, its appearance is very small, no longer like the previous big smoke box mechanical rod nowhere to put.


The market outlook for disposable ecig

There has been a controversial topic regarding the use of disposable ecig. According to scientific studies, the long-term use of e-cigarettes can cause harm to the human body, no less than tobacco. Therefore, it is important not to overuse either type of e-cigarette - after all, smoking is bad for your health. Specifically, the PMTA requires that any new tobacco product be approved by the FDA for legal promotion and that the FDA consider all aspects of the product to be beneficial to public health. Our products can always be sold under the supervision of the PMTA at cost and are prohibited for sale to minors. We have strict guarantees regarding the quality of our products.
