While we've seen concept designs recently really focus on helping the environment in one fashion or another, we haven't seen many that actually focus on two separate causes at once, and aim to fix both of them with one device. The Biolamp concept design is meant to not only clean the air, but also fuel eco cars. The design implements solar energy, as well as the usage of a specialized liquid to make the magic happen.
The Biolamp is designed to convert carbon dioxide into fuel. This fuel is meant to power the street lamps at night, as well as eco-friendly vehicles. It features a pump that literally sucks the smog and other contaminants out of the air. Inside, there's a liquid made from alga and mixed with water. During the day, the Biolamp pulls the smog into the spiral system where the water and CO2 are used to transform the alga into a biomass. Some of it is deposited into the lamp itself to power it during the night.
The rest of the biomass is then filtered through a pipe system underground to a facility that will transform it into usable fuel for eco cars. Seems like a lot of work, especially with the underground tubes to transport the biomass, but the Biolamp's ability to clean the air, as well as provide a seemingly limitless amount of biomass to change into biofuel makes it a unique enough design.
