Earlier this year, an Australian entrepreneur and marine biologist spent 13 days living at the bottom of a lake near Albury, Australia. Llyod Godson, 29, spent this time in an 8-by-10 foot box. Inside were batteries, a bicycle, a bathing suit, algae to create oxygen, and sandwich delivery. He hopes that his time spent underwater will help he and others learn more about sustaining life in a closed ecological system.

His home was made of recycled scrap metal, mostly steel, welded together to make it airtight. It sat on 28 tons of concrete which at on the lakebed. Inside he stored a “biocoil” full of water and algae to absorb carbon dioxide and supply oxygen. His primary source of oxygen, however, were dive compressors, 12-volt compressors floating on the surface above the shelter. A generator made from a modified exercise bike powered a laptop and the biocoil pump. He also used power from onshore methane fuel cells and solar panels.

Godson broadcasted live video to students and experimented with different activities while underwater. He hoped that his stunt would inspire future aquanauts to do the same. The most time ever spent underwater was by Rick Presley who lasted 69 days in 1992. Godson’s next project is to aid Dennis Chamberland in an 80-day stay onboard the Leviathan Habitat off the coast of Florida. This project is set to take place in 2009. With a growing increased in aquatic living, this may be the location of future homes and communities.
