Bioaluminecent lights are wanting to be used to light up the streets of Paris. The take a bacteria gene that produces light in an animal such as a lightning bug or squid. In my opinion this isn't going to work there are way to many problems. The light needs to be intensified the bacteria will only last 3 days and to start it you have toad the liquid solution that will react and produce the light. Also the cost of putting all the equipment in to hold the liquid will be a ton. Not only the equipment, but it will be really difficult to mass produce that many bacteria molecules for the city. I think this type of light should only be used in a house hold for a nightlight or for display.
