An ocean iron fertilization (OIF) method and system for electrochemically controlled release of iron in an ocean to stimulate growth of phytoplankton to increase CO.sub.2 sequestration by the ocean. The system includes a cathode submerged or floating in the ocean; an iron or iron-producing anode submerged or floating in the ocean spaced apart from the cathode; and a power supply unit connected to the cathode and the anode. The power supply unit drives electric current between the cathode and the anode such the anode generates oxygen (O.sub.2) and ferrous iron through electrolysis to be released in the ocean, and the cathode produces hydrogen (H.sub.2) and hydroxide (OH—) species through an electrochemical reaction at the cathode.

A method of chemical extraction from an aqueous solution includes receiving an aqueous solution including dissolved inorganic carbon. The method also includes increasing a pH of a first portion of the aqueous solution to form a basic solution. The basic solution is then combined with a second portion of the aqueous solution to precipitate calcium salts. The calcium salts are then collected.

A method of making building materials from an aqueous solution includes receiving the aqueous solution with dissolved ions and increasing a pH of the aqueous solution so the dissolved ions precipitate from the aqueous solution as salt. The method also includes collecting the salt precipitated from the aqueous solution and forming the building materials from the salt.

A solar powered sediment capture system is disclosed for collecting sediment at environment sites such as lakes and rivers. A mechanical pump directs water from a containment basin to an upper tank and an antistatic pressure tank, both which are elevated. Gravity flow from the upper tank generates vacuum to establish a syphon for drawing a flowable sediment slurry from an environmental borrow site to a filter. Effluent from the filter passes down to the containment basin, which has water level at a lower elevation than that of the borrow site. Anti-static and driller conduits permit gravity flow from the anti-static tank to suspend the sediment and to maintain the slurry at the syphon inlet in a flowable state.

Embodiments provide methods and strictures for purification or volume reduction of a brine by an advanced vacuum distillation process (AVMD) to achieve higher flux by passage of vapors through an AVMD distillation unit. In one example, brine is circulated in a tank. The tank may include one or more membrane pouches that are submerged in the circulating brine or placed above the water level of the hot circulating brine. In other embodiments the membrane pouches are outside of the tank that includes the hot circulating brine but still in communication with it. The circulating brine is heated, allowing creation of water vapor. Using a vacuum, the water vapor is drawn through the membrane, where it may be condensed and subjected to further beneficial use. This process can concentrate to levels to generate crystals or solids, which can be separated and utilized.
