Glowing Algae Striplight
Luminesce is a carbon-negative off-grid modular lighting system.
The light is emitted by bioluminescent algae, which lives in saltwater and feeds off carbon dioxide. During the day it drinks sunlight, and at night it glows blue. Since it casts little light, but still does glow quite clearly, it is used as an alternative to neon, for backlit signage, or for wayfinding. Working off the existing model for farming algae, which is currently done for biofuel, Luminesce houses the algae in clear tubes and a small pump keeps a steady flow of carbon dioxide flowing through.
