CO2 membrane filters
Cheap mineral membrane filters have been developed to seperate CO2 from N2. The mineral membranes acts as a sieve, filtering the smaller CO2 molecules from the larger N2 molecules. They work at temperatures of up to 200°C and, once made, require no additional energy. The mineral membranes are made from zeolite: a mixture of Aluminium and Silicon oxides.

This technology could be used on Venus, after it has cooled down. The membranes would seperate CO2 and N2, allowing the gases to be stored or released seperately, with no additional energy requirements.
Botanists have discovered 15 self-composting plants species. Until now it was thought only soil microbes could convert organic Nitrogen into nitrates and nitrites. It has now been discovered that some plants generate nitrates and nitrites in their tissues as they die.

Self-composting plants will accelerate the build up of nutrient-rich soil on a newly terraformed planet.
Australian scientists have successfully carried out the teleportation of a light beam. The light beam was deconstructed in one location and reconstructed a short distance away. The theory confirms the theory of teleportation is possible for sub-atomic particles, but the question still remains as to whether or not it can be achieved with larger objects.
