North American Carbon Program CH. Support long-term quantitative measurements of fluxes, sources, and sinks of atmospheric CO and CH, and develop forecasts for future trends. The North American Carbon Program was designed to help with the process of providing data needed to model the synthesis activities. The carbon cycle is subdivided into two sections, the rapid carbon exchange, and long-term cycling of carbon through the various geological processes. This carbon cycle occurs in our biological processes, including respiration, photosynthesis, and is generated by autotrophs. Autotrophs (usually photosynthetic) are plants or algae, which capture the carbon dioxide from the air. In water, the compounds removed
Supercritical carbon dioxide heat pumps are commercially marketed in Asia. EcoCute systems from Japan, developed by Mayekawa, develop high temperature domestic water with small inputs of electric power by moving heat into the system from the surroundings. Supercritical has been used since the 1980s to enhance recovery in mature oil fields. "Clean coal" technologies are emerging that could combine such enhanced recovery methods with carbon sequestration. Using gasifiers instead of conventional furnaces, coal and water is reduced to hydrogen gas, carbon dioxide and ash. This hydrogen gas can be used to produce electrical power In combined cycle gas turbines, is captured, compressed to
