soda heat engine

water moving from cold to hot area releases co2 bubbles
  [vote for,

which power a turbine.

a. Water is cooled by pumping it through ice, created at off peak electric prices. b. Air in a cylinder with piston receives heat from solar panels and expands, pushing piston.
c. Piston compresses other air in pressure chamber, which is in contact with cooled water from section (a).
d.the water is pumped back to heating chamber where it is heated by solar panels to 45C +
e. co2 bubbles are released and heated further, pushing another piston which runs a generator.
f. water is pumped back to ice cooler after passing geothermal / wind cooler, and cycle starts again.

       I forgot about this idea, and just found it again. Why the [-1] and why no annotations.   

       Soda is known to give off CO2 bubbles when heated, and to absorb CO2 when cooled, or is my assumption off?

       Not my fishbone, but this seems like an unlikely candidate for Most Efficient System.

       gotta admit the "pumping it through ice" doesn't do much for me, and I don't think you'd be carrying enough CO2 to do more than vaguely annoy any self-respecting turbine.   

       But it might work: you'd have a low-temperature and low-output "steam engine".

       Maybe if I use high pressure at the input (by putting in electric energy to an electric powered air compressor) and leaving the system in a closed circuit (i.e. a tightly closed bottle) Would I then have a type of "Stirling Engine"? Seems to me a coke bottle given a good shake has quite a nice amount of power in it. Would easily throw a toast high into the air...
