An Australian scientist emerged Wednesday after spending nearly two weeks underwater in a steel box, pedalling a stationary bicycle to generate his own electricity and growing algae to convert carbon dioxide into oxygen.
Marine biologist Lloyd Godson spent 12 days at the bottom of a lake in the bright yellow capsule he calls the BioSUB to fulfil a lifelong dream and make a point about sustainable living.
His 10-foot long sub, which was submerged in a lake in the eastern Australian town of Albury.
"It's a pretty amazing feeling, 12 days underwater it went by pretty quickly. I thought it was going to drag on and on and on," Godson said.
Godson used a system of solar panels and a pedal-powered generator to create electricity and recharge his laptop computer, and kept an algae garden to absorb carbon dioxide and release oxygen for breathing.
Godson had to recycle his own urine and waste, but a team of divers delivered food and drinking water to the sub.
For entertainment, Godson watched videos on his laptop and used a wireless Internet connection to communicate with schoolchildren from around the world.
The 29-year-old scientist won funding for the project by winning a 50-thousand Australian dollar (41,840 US dollar) contest called "Live Your Dream" sponsored by a nature magazine, Australian Geographic.
