Carbon from the atmosphere as a printing material

Hi dear people, how about lifting the goals of RepRap to include the eventual aim of using Carbon captured from the atmosphere as the printing material, maybe by transforming it to an artificial material made from carbon nanotubes or similar. We would of course need to print an energy capture component, maybe some form of solar energy capture to provide the energy to concentrate and capture the carbon from the atmosphere. Then the more we print, the more we would be helping to reduce global warming. And the raw material would be free.Trees do it!

On a less far out note, I feel that the speed of the current deposition method is too low, and we should be thinking about maybe creating standing waves in three dimensions using fourier transforms in a build volume containing settable material. It could set mechanically by vibration of very small units designed to lock together with the apporpriate frequency or frequency pattern or fluid to solid via heat or some other part of the electromagnetic spectrum. The standing waves could be emitted from the sides of the build area and calculated to create the appropriate hot and cold spots within the material.

Or some very fine flat extruder grid what only opened certain holes at any one time as it was raised up through the build area, so the whole target object is created by one upwards pass of the extruder grid.

Hi John,

this and other ideas were thoght (and some of them even tested) some ten years ago, but found too complex to realize with the then actual technology ... maybe in 20 to 30 years
