Revision as of 16:25, 2 October 2015

This article is speculative. It covers topics that are not straightforwardly derivable from current knowledge. Take it with a grain of salt. See: "exploratory engineering" for what can be predicted and what not.
There's plenty of building material in the atmosphere. SVG
(variable atmospheric humidity omitted)

Two motivations must be seperated:

  • greenhouse gas reduction
  • carbon extraction for productive use

Carbon dioxide collectors have the potential to fulfill the global energy needs and remove the the excess CO2 that had accumulated due to burning of fossil fuels along with other unwanted gasses of industrial origin.

Devices for the removal of CO2 from the atmosphere do not need and probably should not be able to do self replication. Making such devices macroscopic seems to be a better alternative than making them in the micro- to nanoscale. It makes handling them easier (even collectible by hand) allows for more control and less environmental spill.

  • Carbon extraction must stop at a certain level - otherwise all plants on earth may be in severe danger.
  • Every conscientiously designed mobile (airborne/seaborne) device must care about its fate after their end of service.

Medium

Sub-classes:

  • stationary carbon dioxide collectors
  • mobile carbon dioxide collectors
    Locating solar cells for CO2 recuperation sparsely distributed in the air or on the sea instead of placing them concentrated in one place on the ground may be good for environmental (no pave-over) and political reasons.

Land (more or less stationary)

  • Nanofactories that use air directly as building material.
  • devices looking slightly akin to trees (TODO: what are the benefits of this shape vs flat solar cells)
    placement in inhabited areas - environmental issues!

Water (seaborne)

Concept art of buoy for collection of atmospheric CO2. SVG - mobile carbon dioxide collector buoys

Seaborne mobile carbon dioxide collector buoys of a size that is easy to handle. Swimming units have the benefit of easier access to wind power and easier propulsion. They can easily be kept stationary. They need only plain air as lifting medium can use the wind for propulsion and are easier to collect manually (skimming) if something goes wrong.

Air (airborne)

Micro airships:

  • have a very lightweight bubble as main body in a size range between 10um and 100.000um
  • use depending on size thermal heating or hydrogen for lift
  • use their surface for harvesting of solar energy
  • are capable of water capture and splitting for compensation of hydrogen diffusion loss
  • may be capable of carbon dioxide capture and splitting
  • may be capable of self replication
  • may (if malicious) create some nasty gasses

Extraterrestrial application

Questions

  • packing and shipping CO2 or preprocessing it right away?

To investigate: If replicative how fast could they replicate (doubling time) depending on their diameter?
What is the limiting factor: solar-power for hydrogen generation, diluteness of CO2 or something else?

To investigate: Can they be made to actively propel themselves? Their high volume to mass ratio makes this rather difficult when there's even the slightest bit of wind. Flattening the bubbles drops the aerodynamic resistance significantly.

To investigate: AP manufactured solar cells & mechanosynthetic carbon dioxide splitting
