ori Zimmer writes in inhabitat that designer Gyula Bodonyi has harnessed the power of green algae in a light bulb. With the Algaebulb, algae powers a single LED activated by a tiny air pump and hydrophobic material able to create a tiny power house for light.
The tear-shaped bulb is made up of an air pump, LED, hydrophobic container, PC Shell, and air outlet. The system sucks in carbon dioxide and water through the pump near the E27 screw-top, and as the air passes through the bulb, chlorella pyrenoidosa microalgae are fostered. While algae flourishes, it gives off oxygen, which in turn powers the tiny LED inside.
When the AlgaeBulb is not illuminated, it appears to be a dark green; a result of the colony of microalgae living within. When illuminated, it gives off a slightly green tinge on the interior, making for a green bulb that is literally “green.”
