How To make a bioluminescent Lightbulb from dead Squid

Tolles Tutorial auf Instructables für die Zucht von Bakterien, die auf Oktopussen wachsen und mit denen man biolumineszierende Glühbirnen bauen kann. Mein Traumhaus ist durchzogen von einem Aquarium-Röhrensystem (das man niemals saubermachen muss) und wird beleuchtet von Bakterien und lebenden Energiesparlampen. Es gab vor 'nem halben Jahr eine Designstudie eines Elektronikherstellers nach demselben Prinzip und das kann man sich jetzt nachbasteln.

This instructable will show you how to grow and culture your own glowing bacteria […] from fresh sea fish (squid work well) and culture it onto special agar gel that you can make at home or simply buy ready-to-pour. The gel can be formed inside all kinds of things that you want to make glow a cool greenish/blue color!

The glowing vibrio bacteria are marine life forms that live alone or in a symbiotic relationships with fish and squid inside their light organs or as parastites. Alone the bacteria don't really glow but in groups of large enough number something amazing happens called quorum sensing. The bacteria upon realizing they have enough of each other around turn on genes that allow them to GLOW! The light that is emitted is super efficient around 98 % meaning that only 2 % is lost through heat, thus the light is cool and that's very COOL.
