Italian architect Carlo Morsiani would like to take Amsterdam's canals from dark, dank and filled with old bikes, to brilliant, blue, and presumably still filled with old bikes. Morsiani recently proposed adding bioluminescent members of Photobacterium to the city's waterways. With the canals stocked with motion-sensitive bacteria, any passing boats or accidental swimmers would leave a hazy blue trail in their wake.
The idea is not entirely untenable – bioluminescent organisms congregate in such density in Vieques, Puerto Rico, that the bay has become a tourist attraction. Since these tropical organisms produce only weak light, Morsiani has a lot of genetic modification to work out before these bacteria can adjust to life in Europe. Add glowing canals to buildings coated with Photobacterium and transgenic streetlight trees, and we might never have to change a lightbulb again.
