> 1 tonne of CO2 gives ~137 kg of methane at 100% reaction yield, due to the molar weight ratio of CO2 to CH4.
I think it’s more like 363 kg given the ratio of molar weights: http://www.wolframalpha.com/input/?i=co2%20molar%20weight%2F...
(Looks like an extra factor of two, but I can’t figure out why, everything I play with in WolframAlpha is a factor of two in the wrong direction)
