I hope you're sitting down and try not to laugh too hard.
Terraform@home
This would be a project to find the most effective and efficient method to terraform a planet. In this case we'll use Mars as an example. The end result should be a habitable planet to support human life in comfort. No domes, no bulky space suits, just a place you can walk around like here. It should be able to support food production and biodiversity. Using computer modeling to determine the long term effects of changes to the planet. As an example, I'm no scientist but I know that carbon dioxide causes a planet to warm up. Instead of carbon capture and storage what would happen if we captured it and sent it to Mars. An atmosphere would start to form and as a greenhouse gas it should start to warm the planet. As the planet warms the frozen water deposits thaw and then you can start to send in things (plants) to convert carbon dioxide to oxygen.
The modeling would probably be similar to CPDN and I'm sure there are enough scientists out there with ideas and enough planets that would keep the project going forever. Is it a pratical or usefull project? I don't know but you have to admit I've given you a unique idea for what to do with this worlds excess carbon dioxide.
I'm starting to get the idea that I'm the only one here that reads science fiction.
