Deep water plan seems

It turns out that the specific gravity of CO2 in liquid state is higher than that of water. Even seawater. And the ocean is deep enough that if you pump it way down, the pressure will put the CO2 in liquid state. So it's technically possible to sequester CO2 that way. But there was a lake in Africa that used to have a lot of CO2 in it, and one day for whatever reason it was suddenly released and the village on the shore died. Not something that would be good to have happen on the kind of scale it would take to affect climate. And perhaps not healthy for the Badass and Delicious things on the bottom. --------------------------------------- Badass! (and delicious)

These ferns still exist all over the north central part of the continent, and are considered major pests interfering with recreational use of lakes and streams. Eradication efforts have not succeeded. They grow very fast and guzzle CO2 like nobody's business.

There was a well regarded documentary some while ago about how carbon moves around in the world and it touched on the industry in the Gulf. I can't seem to find it, unfortunately, as I seem to have mis-remembered the unusual scientific term for the intense level of CO2 dissolved, but there is CO2 sequestration happening. ISTR it wasn't planned; it was "just happening". Wade. Static Scribblings http://staticsan.blogspot.com/

To try and stem the build up... they have a pipe that goes to the bottom of the lake with a dome on the bottom (3-4 ft in diameter) They pressurized all the water out of the pipe and then "let go" the pressure. This caused the liquefied CO2 to decompress and begin a process that continues to this day. The GAS IS light and travels with great speed towards the surface, in the pipe. It carries CO2 laden water and other gases with it and spews about 70 feet above the water surface from the pipe. Its not enough to eliminate the build up, but evidently based on some estimate, it should help with the frequency of these massive out-gassing. There is another lake in Africa that also has Methane build up of same proportions... They are doing a similar thing but using the gas to power Electrical turbines and other items.
