SYDNEY, Australia (AP) – An Australian scientist emerged Wednesday after spending nearly two weeks underwater in a steel box, pedaling a stationary bicycle to generate his own electricity and growing algae to convert carbon dioxide into oxygen.
Marine biologist Lloyd Godson spent 13 days at the bottom of a lake in the bright yellow capsule he calls the BioSUB to fulfill a lifelong dream and make a point about sustainable living.
Godson used a system of solar panels and a pedal-powered generator to create electricity and recharge his laptop, and kept an algae garden to absorb carbon dioxide and release oxygen for breathing.
