This chandelier does more than just light up a room—it also purifies the air. The eco-friendly lamp is made up of 70 glass “leaves” filled with water and algae. These tiny, plantlike creatures use light from the chandelier’s LED lights and carbon dioxide from the air to create their own food. This process, called photosynthesis, releases oxygen as a by-product. The lamp helps produce clean, fresh air indoors just as trees and plants do in nature.

London artist and engineer Julian Melchiorri designed the chandelier, named Exhale. He says that it shows how biotechnology—technology that uses biological processes for industrial purposes—can improve our quality of life.
