View Full Version : Biologist emerges after two weeks in urine-fuelled sub

BREATHING air provided by algae watered with recycled urine, and pedalling a bike for electricity, an Australian aquanaut emerged today after 13 days living underwater in a "biosub".

Lloyd Godson entered the 2m by 3m yellow biosub capsule, submerged in a former quarry on wetlands near the southeastern town of Albury, on April 5.

His survival at a depth of 5m hinged on a coil of green algae which provided air in return for Mr Godson urinating on the plants each day.

"I will be glad to get out in the sunshine and fresh air again. I have even had thoughts of running like Forrest Gump, and just not stopping!" Mr Godson said before surfacing.

Godson, 29, a marine biologist, got funding for the project after winning a "Wildest Adventure" competition run by nature journal Australian Geographic.

A team of divers provided meals to the capsule through a manhole in its base, while some electricity came from the bike and some through a bank of onshore solar cells.

A single daily blast of fresh air was also provided from above, after trial and error with levels provided by the algae "biocoil", Ms Sarasiti said.

"It's never been done before using air from the plants," she said.

The experiment had been designed to prove whether an underwater environment could be self-sustaining.

Entertainment in the capsule came from a drum kit which Mr Godson could use at all hours without upsetting neighbours other than fish.

I wouldn't mind living there for a couple of weeks. What an interesting concept...I wonder how much of that could be adapted for land, to make our lives a little greener...

And pedaling the bicycle for electricity? That might solve a lot of health issues too.

I really liked the notion of entertaining yourself with a drum kit. Most of us would settle for an iPod and a paperback.

I wonder whether they were spotted drums?

No, don't start. Must...resist....

Terry, it was a quarry, therefor must have been freshwater drum.

He'd have to stay well-hydrated to make sure he produced enough urine to keep the algae alive... sounds like an interesting concept, overall. Just think, in a few years we'll have new submarines powered by the sun and navy boys pedalling really hard ;)

I wonder how much air was in that "blast".

So, algae + urine = air? I'm coming up with this new idea for a spare air device. I'd tell you about it, but I need to get a patent first.

I guess that means that if you piss while diving in the St. Lawrence after July, you should be able to breath without a reg?

You first.

So to a minor extent, Sci-Fi hits home again. I don't know how many Sci-Fi flicks featured ships with hydroponics that were used to both grow food and produce breathable air.

Pissing on algea though???

Weird science indeed.
