Text speak is never a good idea if you want to be clear!

You have 3 choices - a CO2 powered rocket - see cork rocket on the right.

OR the CO2 must drive some kind of piston based engine. See http://www.john-tom.com/html/Engines.html

OR Drive some kind of turbine. Much depends on how much CO2 you get and how much pressure you can generate.

Not a clue: try again in English ?

Chemicals in the bottom of the reaction vessel, gas exits near the top.
