How much perflourocarbones we will need to warm up Mars to Earthlike temperatures?
Offline
Using this calculator ; http://www.users.globalnet.co.uk/~mfogg … raSim.html ; I calculated that only 1 microbar of PFCs will be needed to warm up Mars to an average temperature of -1.5 degress Celsius and create a 314.62 milibar primarily CO2 atmosphere from sublimation of polar caps and regolith.
A good start.
How much PCF you will need to create 1 microbar of it in the Martian atmosphere?

About 4 billion tonnes.

I did a web search, Dupont projects to a need for 68,000 tons of R-22 refrigerant in 2010. That's an HCFC but it gives you an idea. However, if you look at the oil industry instead of the fluorocarbon industry you get different results. Canada produced 4 million barrels of oil per day in 2005. There is 6.15 barrels of bitumen per metric tonne, that's the stuff that comes from tar sands. So that means 650,000 tonnes per day. At that rate it would only require 6150 days, or 16 years and 10 months. So, can Mars produce as much PFC per day as Canada produces oil? You would need a major deposit of fluorine mineral.
