Researchers at the Technical University of Denmark have turned to nature in search of a renewable source of energy that can light up cities at night but without guzzling any electricity.

Bioluminescent microalgae, which like solar cell stores sunlight during the day and releases this energy in form of light at night, could be ideal for developing bio-lamps for sustainable cities of tomorrow, notes

For the idea to turn into a reality, scientists must first isolate the genes for bioluminescence and transfer them to larger plants that can emit light more efficiently and for longer durations than algae does in its natural state, writes Tree Hugger.
