Bioluminescence is a living organisms’ ability to emit light. It has inspired Pani Jurek to create eco lamps. Together with Stanisław Łoboziak, a biologist designer created a lighting fixture that can emit light without the necessity of supplying them with electricity. In nature, bioluminescent diatoms can be observed, when waves full of diatoms hit the shore and the water flares blue magical light. Diatoms do not emit light during the day, it occurs only during the night and when they are in motion. The energy needed to produce the light is gained during photosynthesis. The lamp enriched in the diatoms can emit light for six to nine months depending on the pace of the diatom’s growth. The process may be prolonged by simply diluting the cultivation to renew the whole process.
