One of the differences to other previous stations is the fact that it is not only available for a small group of scientists, but to a large group even of private participants. Of course, it still requires a very strict program to enter the station. The idea is to settle the station inside a park (The Calamar-Park) and make it available for all sport divers. For this touristic purpose a row of activities and attractions has to be designed. These attractions will follow a chronological program to maintain continuous popularity. That means that when an attraction reaches its half-time period another attraction should be already on its way as seen in the following graph: Continue reading “Undersea Station: Event Plan”
For a long time we favoured the shape of a sphere mainly because there were ready structures available used as pressure resistant LPG tanks. It would have measured 12m in diameter, the lower half would be filled with sand just before lowering while the upper half would contain two floors of living space. After discussing the idea with different engineers we had to accept that a LPG tank would need so many modifications that building a new one would be even cheaper. After receiving the first cost estimations we were pretty sure that it would be impossible to find funding for a civil structure of that scale.
Keeping an air filled structure on the sea-floor is more difficult than expected. Especially while descending and landing the station major difficulties occurred on previous stations. We can calculate about one kilo of weight (negative buoyancy) per litre of air inside the station (positive buoyancy). The dimensions are huge: imagine a space of 50 m² with a height of 2m, which equals 100 tons of counterweight. At the same time it has to be considered, that these weights have to be lifted again in the end of the mission. For ecological reasons we should find a way to leave the weights on the site and to use a material that would not harm the environment. Continue reading “Undersea Station: Ballast”
In our undersea station one of the ways to absorb Carbon dioxide from the air and to produce oxygen instead might be beside classic scrubbers the Biocoil reactor that was first introduced by a science class of Cascade High School in the US. It looks like a quiet simple system based on Chlorella algae and it was used in Lloyd Godson’s ‘BioSub’ project.

One of the reasons why the first generation of underwater stations came to an end in the 80’s was the conlusion that it is more effective to use decompression chambers on board of a support vessel instead of placing divers on the bottom of the sea. The oil industry just did not see any reason for undersea stations. Therefore it was surprising that China announced in 2012 that they planned to build an undersea mining station of 60 meters length Continue reading “Chinese Underwater Station”
