Lloyd's next adventure

We extensively covered Australian Lloyd Godson's underwater Biosub expedition. He spent 2 weeks earlier this year in an underwater habitat that used a bio-regenerative life support system. Since then he has been busy preparing his next adventure. From their website:

The Australian marine biologist Lloyd Godson and his Greek partner Carolina Sarasiti, will 'migrate' 500km through the Ionian Sea off the west coast of mainland Greece during September - October 2008. They will do so in two custom-built human powered fish shaped submarines designed by pioneering Greek engineer, Alex Sarasitis. The submarines, 'Ulysses' and 'Penelope', will explore the secrets of the ocean in a unique and unusual way.

The submarines will be using some unique technology:

The scientific and technological part of our mission is true innovation. The submarines will be designed and built by project Engineer Alex Sarasitis and will utilise a hydrofoil tail fin attached to the pilots legs for propulsion. The foil angle will change automatically producing an 'automatic transmission' effect making it the most efficient way of swimming. This new fin technology will be used by Herbert Nitsch, "The Flying Fish", during a Constant Weights World Record attempt in 2008. Alex's designs will be based on the motion and shape of fast swimming fishes such as tuna and mako sharks, giving them the fastest form possible. The “dry” submarines will be built from carbon fibres, giving rise to a new species of fish: the Carbon Fin Tuna. They will be capable of diving to approximately 50m with a clear polycarbonate dome serving as the viewing port. Both submarines will be equipped with video cameras for observation and research, as well as an advanced communication system and sophisticated diving equipment for safety
This is an exciting and worthwhile project and we will provide further reports in the future.
