Chandelier containing living microalgae to "purify the air"

Artist, inventor, and bio-hacker Julian Melchiorri created "Exhale, the Bionic Chandelier," a hanging electric light that "purifies the air indoors through photosynthesis performed by living microalgae enclosed into leaf modules." Exhale is now part of the Victoria and Albert Museum's permanent collection. From the project page:

Exhale is also the first living object which continuously grows while performing biologically-driven depurative functions. The light of the chandelier illuminate the space but also stimulates photosynthesis performed by tiny microalgae, this living microorganisms feed on carbon dioxide while releasing breathable oxygen into the room. This biological process performed by the chandelier establishes and explores a new symbiotic relationship between object and people where life-giving resources are constantly exchanged, and where each other waste enables respective metabolic processes. This exchange recalls how biospheric systems work, where waste ultimately doesnt exists but is a valuable resource for other elements in that system.
