The mass of co2 injected can be quite high.

however using sublimation of co2 is retarded. the work one can extract from exanding gasses, which draw in heat is near nothing. it is for sure an energy losing process.

co2 is a "dead" molecule, no more energy can be extracted from it.

sheesh.

/thanks for the laugh tho. storing energy as sublimated co2.
//and what about the heavier than air vapours?
///everyone following such a vehicle would probably hyperventalate and pass out, maybe die if the conc. gets high enough

Hi - Gilgamesh , you say:

co2 is a "dead" molecule, no more energy can be extracted from it

(I know what U mean ... BUT)

CO2 - is the most important thing actually ... and I therefor disagree 111%

for one -CO2 is "food" for all the green suff around , included algae .. hocus-pocus- there we have meat and fish

-secondly - the byproduct from the photosynthesis in "our dear" oxygen

CO2 is not dead at all - "what is dead though, are the braincells inside the US governmentals heads - or maybe they are throughoutly boneheads over there (?)", I dont know really.

=> this message hereinafter is mentally beamed to the US Senate - and not for TODers, because U are among us nice thinkers :)

I must say quite frankly- that I am very fed up and provocated over the US attitude on climate - and also over the idea of not embedding politics concerning peak-oil and beyond (today)
Remember- you 4% of world population grab and burn 25% of the oil- goods and U flash wars over it and threatens all over the place - it really scares me , and it should also scare the am_voters!

Let history be history - the overwhelming content in the IPCC-report is only understood,acknowledged and "approved" recently by most UN countries -
BUT the US...Australia and a few other "bad" parties does not comply - WHAT do you say ... ? .... You will find YOUR OWN SOULUTIONS ... HAAhhhh? I bet you will, as YOU roll out new SUVs and take the "bio-hal-lelujahs"...and the more "cartoonish hydrogen-hal-lelujah "...

Can americans be re-programmed to skip the idea of car ?
( or at f**** least go fore small tiny-cars. Fro starters..)
