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.

Wireless Sensor Network (WSN)

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)”

Undersea Station: Biocoil

(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.

What happened to the artificial gills?

© CalamarPark.com The Triton is a sort of artificial gill that would extract oxygen from the water for you in an on-demand fashion as you swim, obviating the need for bulky SCUBA gear. Is this really possible? Find the answer on Deep Sea News.

CO2 Scrubber

Longer stays in an underwater station require systems to filter out Carbon Dioxide (CO₂) from the air that is exhaled by the aquanauts. These CO₂ scrubbers generally consist of a fan that pulls air through a canister filled with Carbon Dioxide (CO2) adsorbent, such as Sodasorb or Sodalime. To get a rough idea about CO₂ scrubbers and their prices visit the webpage of AMRON International.

About CalamarPark.com

CalamarPark.com is an independent ‘Initiative for Studies on Aquanautic‘. Our aim is to develop a new generation of modular, serial underwater habitats for human occupation with emphasis on human scale and habitability. The facility and its mobile module will be open to several interdisciplinary applications, such as underwater archaeology, specialized tourism, space training missions etc.

Within this scope we are convinced that this is the best approach to attract attention for the marine habitat and increase interest to its environmental issues.
