Breathing Gas Processing: Overview

(Update 11.03.2023: structure renewed) This article is intended to define the concept for ensuring the appropriate habitat atmosphere to be used in the Calamar Park modules.

It is divided into the following sections:

Guide Value for Electricity Costs
Oxygen
Oxygen Demand of a Human Being
Oxygen Availability
Carbon Dioxide
Normoxic Gas Mixtures (Normox)
Air Supply from the Surface
Carbon Dioxide Scrubbing by Soda Lime
Carbon Dioxide Scrubbing by Monoethanolamine (MEA)
Carbon Dioxide Scrubbing by Sea Water
Photosynthesis
Water-Air Membrane
Oxygen by Electrolysis

Our extensive analysis and proposals are part of the design manual.

Vent Base Alpha

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.)

Underwater Navigation

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).

Bioversal Fire Extinguishers

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.

Leben und Arbeiten im Meer

(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”

The Gig on the Rig

If you have doubts whether concrete is an appropriate material for an underwater habitat then have a look at the supporting legs of Troll A, a condeep offshore natural gas platform in the Troll gas field (see Wikipedia en/de). The legs are air filled and reach 303m into the deep. In 2005 Katie Malua performed a concert on its basement setting a world record for the deepest underwater concert.

Living and Working in the Sea

(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.

Worst Case: Lightning

This chapter aims to find preventions and handling to reduce risks of a lightning strike.

It should be compatible with the Worst Case Scenario introduction and includes the following sections:

Coverage
Introduction
Critical Phase before and after a thunderstorm
Preventive Measures
Sources

Our extensive analysis and proposals are part of the design manual.

Hypodynamia of the Eyes

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”
