The ultimate green light: an algae-powered lamp


Inspired by a recent experiment in which scientists at Stanford University and Yonsei University in Seoul generated an electrical current from algae during photosynthesis, Netherlands-based designer Mike Thompson has created a prototype for an algae-powered lamp, Designboom reports.

Thompson described the energy-efficient Latro lamp as a "living, breathing product," much like a pet. Algae needs only sunlight, carbon dioxide and water. "Breathing into the handle of the lamp provides the algae with CO2, whilst the side spout allows the addition of more water and release of oxygen," Thompson writes on his website.

Energy is stored in a battery, ready to be used when the sun goes down. For further details, go to www.miket.co.uk.

This is great. But how exactly is the power converted from the algae to the battery?
