In 2016 deep sea technology developer Dr. Phil Nuytten had a TEDx speech about his vision of an underwater habitat called Vent Base Alpha. It would generate the necessary energy from the geothermal vent next to its location and would consist of a 1bar environment. (Video length 19:08 min.)
The danger of excursion divers getting lost have always been a major concern in underwater habitats. According to their webpage the Dive Tracker consists of a sender and a tracker. From a distance of up to 4000ft (≈1300m) divers can easily track the direction of the sender’s signal and return to their safe location. Costs: from 1200USD per set. (Homepage Dive Tracker).
(Updated 24.05.2018; added wet room configuration, scuba tank refilling installations and summarizing requirements list) Surely one of the most complicated area of an underwater structure for human occupation is the habitat entrance. It is the local water-air interface, vulnerable to changes in pressure by tidal movements on the surface of the sea; its hatches have to bare potential pressure differences between the habitat interior and the surrounding water; no object that is only a little bigger than the greatest diameter of the entrance can be brought into the habitat. It is constantly wet and humid and the only gateway for medical assistance. But to see in detail let’s have a look at the different sections of the entrance complex. Continue reading “Habitat Entrance”
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”
(For English please scroll down) (Update 17.01.) Nachdem wir uns mit Dr. Jim Miller und Ian Koblick auf eine Übersetzung ihres Buches ‘Living and Working in the Sea’ ins Deutsche und insbesondere vom anglo-amerikanischen ins metrische Maßsystem geeinigt haben, können wir nun bekanntgeben, dass die Übersetzung inzwischen abgeschlossen ist. Momentan arbeiten wir an der Durchsicht und hoffen, in Kürze die Veröffentlichung beginnen zu können. Mit letzterem ist innerhalb der nächsten zwei Monate zu rechnen.

In this category we would like to list potential “Worst Case Scenarios”, their prevention and handling. “Habitat Flooding” is the first of this series. Others are about to follow.
This chapter aims to find preventions and handling to reduce risks for the case of a habitat flooding. All proposals that may help to improve it are welcome. Continue reading “Worst Case: Habitat Flooding”
This chapter describes an estimation of probable hypodynamia/atrophy of the eyes as a potential health risk during long-term durations in an undersea habitat. Continue reading “Hypodynamia of the Eyes”
I know, it’s a bit off the topic, but if we succeed one day to have a kingsize underwater habitat, I want one of these !!! Get all information on the HiCan project on hi-can.com
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”
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. Continue reading “Augmented Reality Underwater”
Updated 06.03.2017 – The Digital Data Processing of the station will be of major importance. Beside the conventional functions of the IT systems we should use the opportunity to establish a completely new approach concerning the User Interface (UI) and the system’s interaction with the aquanauts. Continue reading “Undersea Station: Data Processing”
Here is an idea for a porthole where the structure of the underwater station does not allow to install one. For example on the ceiling, where penetrations of the shell should be strictly avoided in order to maintain the integrity of the emergency safety area in the upper part of the living area. The Virtual Porthole would consist of a camera on the exterior of the shell and a TV flat screen on same position inside the habitat. Continue reading “Underwater Station: Virtual Porthole”
To provide food to the Aquanauts might be more difficult than thought concerning changing weather, water/pressureproof transportation, as well as emerging odours and chemical compounds inside the habitats atmosphere. A complete or partial solution could be a meal replacement like Mana. MANA is a balanced food providing all nutrients the human body needs. It comes in the form of drink or powder being produced in Prague. Learn more on their webpage.
To stay in an underwater habitat longer than 12 hours means to stay under saturated conditions, which requires an aquanaut decompression sequence of at least several hours. This decompression procedure is very critical: if any of aquanauts gets into an emergency situation, there is no way to take him out of the chamber before the sequence is finished. If the procedure is badly designed there is no way to bring a paramedic into the chamber. For the period of several hours the aquanaut would be alone with his companion. Continue reading “Aquanaut Decompression”
Check out Wikipedia for all information about the history of Underwater Habitats. We just finished the preparation for the same article on the German Wikipedia and will continue to add the results of our investigations there.
