Abstrakt:

Conversion of the gaseous system CO2-N2-H2O into solid mixture of amino acids and other products appears to be important technology for several reasons.This process may contribute to lowering of CO2 abundance in the atmosphere. Carbon dioxide annual emissions produced by human activities in burning coal, oil, and natural gas and by transport, amount to over 7 billion tons of carbon or almost 1% of the total CO2 mass in the atmosphere. Carbon dioxide emissions are responsible for over 60% of the "enhanced" greenhouse effect, which is influencing climate changes. If nothing is done to reduce CO2 emissions, current climate model predicts a global warming at about 1 to 3.5 oC by 2100. The Earth's average see level is predicted to rise from 15 to 95 cm due to the global melting of glaciers in Greenland and Antarctica. The frequency and intensity of extreme events such as storms and hurricanes may change. The altering in ocean circulations, such as is the Gulf Stream, can also take place. So, carbon dioxide enter the natural CO2 cycle, in which many billions of tons are exchanged naturally each year between the atmosphere, oceans and land vegetation. This exchange must be precisely balanced. However, after industrialization since 1800, the free CO2 levels have increased by almost 30% and they continue to increase by almost 10 % every 20 years.
