(Guest article by user Mike, thanks for contributing) By common definition, Branch & Bound is a mathematical algorithm to solve integer optimization problems. But simplified versions of Branch & Bound are also applied to find best fitting technical solutions manually. It is a useful tool for making fundamental decisions, such as the selection of a synthesis route during the project development of a new chemical factory complex.
In the context of CalamarPark, the design of the underwater habitat is such a fundamental decision: Should it be small or large? To operate at what depth? Ambient or atmospheric pressure? A certain design might be perfect at one location, but only second choice at another. Continue reading “Branch & Bound”
(Update 29.08.2018: Added water air membrane; oxygen by electrolysis. Dieser Artikel steht unter “Atemgas” auch auf Deutsch zur Verfügung) This article is intended to define the concept for ensuring the appropriate habitat atmosphere to be used in theCalamar Park modules.Continue reading “Breathing Gas Processing: Overview”
(Update 29.08.2018: Wasser-Luft-Membran und Sauerstoff durch Elektrolyse hinzugefügt; the english version of the following chapter is available under “Breathing Gas Processing“) Dieser Artikel soll das Konzept zur Gewährleistung der geeigneten Habitat-Atmosphäre festlegen, das in den Calamar-Park-Modulen verwendet wird.

(Update 22.06.2018: Expanded list of proposed scenarios) In this category we would like to list potential “Worst Case Scenarios”, their prevention and handling. The results of each scenario naturally link to two different applications:
structural measures of the habitat (to be considered during planning and construction of the habitat)
emergency procedures (to be considered before accommodation)
The kind of fire extinguishers for an underwater habitat is an important issue. It should be effective, but must not contaminate the entire atmosphere. A considerable solution might be the Bioversal technology represented by Gröschl Brandschutz GmbH (former Bioversal Umwelttechnik und Handels GmbH) in Austria. Continue reading “Bioversal Fire Extinguishers”
BIOSMHARS was a 2-year (2011-2013) research project co-funded by the European Commission under FP7. It was the first phase of a joint EU-Russia research effort to develop the scientific and technical tools for a comprehensive approach to the challenging issue of biocontamination inside manned spacecrafts. (project page; final report as pdf)
Update 27.04.2018: added new renderings) So far the final draft follows the hangar shape. Having a look at the evaluation list in the ‘Structural Shape‘ chapter it seems like the ideal shape for the undersea station.
Because of the sand used as variable ballast and the space under the station the structure is easily removable by just releasing the sand. No harmful materials or items would be left behind which serves the ecological idea. Continue reading “Undersea Station Draft No.4: Hangar”
(updated 25.04.2018; added preliminary renders)Project CalamarPark Undersea Station aims the development of a new generation of undersea settlements. Technically based on experiences of prior stations there will be several new considerations concerning expandability, size and usage. All results will be open-source (except some marketing details necessary for continuous popularity) and anybody who is interested has the chance to contribute his ideas. Until the minimum financial frame is completed we will go on collecting as many information as possible, implement them to a realistic blueprint and constantly improve the final design. Ultimately the final goal is the actual building of the habitat. Continue reading “‘Project Undersea Station’ Introduction”
(For English please scroll down) Zur Erinnerung: Ich hatte mich mit Dr. Jim Miller und Ian Koblick auf eine Übersetzung ihres Buches ‘Living and Working in the Sea’ (‘Leben und Arbeiten im Meer‘) ins Deutsche und insbesondere vom anglo-amerikanischen ins metrische Maßsystem geeinigt. Die Übersetzung und erste Durchsicht ist abgeschlossen und alle notwendigen Kontakte geknüpft. Der ursprüngliche Plan, die Veröffentlichung über Crowdfunding zu finanzieren, hat jedoch einen Dämpfer erhalten, weil alle Crowdfunding-Plattformen Projekte aus dem Land, in dem ich seit langer Zeit lebe, nicht akzeptiert. Ich brauche da also eine andere Lösung. Continue reading “Leben und Arbeiten im Meer”
Several years ago Benjamin proposed a system of sensors inside the habitat measuring all necessary parameters like oxygen, carbon dioxide etc. and communicating among each other. Last days we talked about it again and found out, that it would still be a good solution. So we decided to publish it here again. Below you find the original thread, translated from German: Continue reading “Wireless Sensor Network (WSN)”
(Updated 07.06.2017; added crowdfunding, daily turnover by educational institutions and underwater archaeology) The most professional underwater habitat so far is still the Aquarius habitat in Florida. This quality comes to a certain price of $1.2 to $3 million per year. Due to budget cuts, NOAA ceased funding Aquarius habitat after September 2012, with no further missions scheduled after a July 2012 mission. It was a very exciting period having the facility on risk. It took until January 2013 when a proposal to keep Aquarius running under Florida International University administration was accepted. What could we do in future projects to avoid sooner or later close-downs by lacks of financing? Continue reading “Financing an undersea station”
While talking with Mart about the funding of a simple underwater habitat for a first proof-of-concept, I wondered what would be the cheapest way to bring a subsea station in operation. In other words, what is the rock-bottom price for a simple solution that would allow at least two divers to spend a couple of days below the water surface? Continue reading “Guest Article: Cheapest Habitat”
(Updated 04 April, 2017) 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 in 2007.
The Biocoil and BioSUB Projects on ABC’s Behind The News (BTN):
The Calamar Park Digital Library is updated. There you will find all kind of relevant images, articles, manuals and reports about underwater stations and related subjects. For access contact Mart by mail.
Solar power and an undersea habitat does not seem to fit each other. But in 2012 I had the idea of a device that opens its harvesters only if the conditions are appropriate just like a hibiscus blossom at dawn. I called it a Solar Lily. Continue reading “Solar Lily to power undersea station”
How helpful would it be to have Augmented Reality underwater in a closed environment like an Undersea Station? NASA experimented with Augmented Reality (AR) or Mixed Reality (MR) by using Microsofts HoloLens at the Aquarius Reef Base off the coast of Key Largo, Florida, in late July/August 2015. Potential astronauts used the device for tasks like checking emergency breathing equipment. Therefore they were going through a series of steps ranging from turning valves to finding and plugging in equipment, and setting up equipment to support an undersea robot.
