Algae Station is covered by a large photobioreactor, which circulates water filled with algae. Algae is up to 400 times more effi- cient than a tree for removing CO2 from the atmosphere when used with a photobioreactor. Algal oil is extracted and chemical- ly converted into biofuel to power cars. Then, the carbon dioxide emitted by vehicles that run on biofuels is reabsorbed by pho- tobioreactors. This creates a cycle that avoids the damage caused by carbon dioxide.

The oxygen bar uses Chlorella Vulgaris. Due to its robustness and adaptability, Chlorella Vulgaris can grow over a wide range of pH and temperature levels and carbon dioxide concentrations. The refuelling area uses Spirulina. It can remove up to 80% of nitrogen and phosphorus from domestic wastewater.

The car refuelling area is an entirely self-service facility. The top of the refuelling unit is connected to the biofuel pipeline. The height of the service unit is 1.3 meters to facilitate self-operation.

The oxygen bar is an open plan. The sides of the oxygen bar are covered by glass. The front and back area is open. In the middle, there is a swing made of photobioreactor tubes. The swing is equipped with an oxygen intake tube for people to take in oxygen while resting.

The algae-filled water is circulated in a photobioreactor, continuously producing oxygen. Each station has three open oxygen bars with seats and stretchable oxygen tubes. While people wait for their cars to refuel, they can take a break in the oxygen bar next door to get fresh oxygen.

The station also has three fountains that provide purified water through algae.
