Best option would be to get the CO2 from the atmosphere as we are all aware, let's see the implications:
=> extensive growing surfaces with ample water, nutrients and sunlight => the oceans provide all that, as discussed before => it occurs to me we could use the natural ocean streams as "conveyor belts" => a closed loop conveyor belt running around, or even constituting, the growing surface would be nice => how about using the Gyres ( http://en.wikipedia.org/wiki/Gyre ), for example the North Atlantic Gyre (you know, that current aka Gulf Stream in some places which makes winters so cold on US Atlantic coasts and so wonderfully temperate here ;-) which circles the Sargasso Sea: Let's see what Wikipedia says on our putative "NATO" (North Atlantic Turning Oilfield ;-) at http://en.wikipedia.org/wiki/Sargasso_Sea : "The Sargasso Sea is an elongated region in the middle of the North Atlantic Ocean, surrounded by ocean currents... Portuguese sailors were among the first to discover this region in the 15th century, although it may have been known to earlier mariners, as a poem by the late 4th century AD author Rufus Festus Avienus describes a portion of the Atlantic as being covered with seaweed. Christopher Columbus and his men also noted the Sargasso Sea, and brought reports of the masses of seaweed on the surface." (emphasis is mine) We might be able to harvest the native seaweed and/or grow better suited algae ... what do you think Vorts, shall we farm the Sargasso Sea and push the harvest onto the North Atlantic Gyre for cheap transportation? Or would it be better to simply farm the Gyre? Or is this a "sea lea" idea? ;-) Michel
