Not bioluminescent: "Cajella’s lamps consist of algae-filled water along with a light and battery system. During the day the algae produce energy from sunlight that is then stored in the batteries. Then at night the energy is used to power the light. However, as the algae can also produce energy from carbon, sunlight isn’t required for the process to work." Sunlight/carbon -> Energy -> Light if I'm reading this correctly. Also: "However, the good news is algae can also act as a biofuel once separated from the water, so even if the lights need a water change out every so often, the waste algae just forms another type of fuel where as the water can be recycled." So once it sequesters all that CO2, it can be released back into the atmosphere by burning it?
