Elementary process identification of solar carbon dioxide (CO2) fueling

With the respect to the negative roles of carbon dioxide on our climates, it is
obvious that it is the time for the development of processes that convert CO2 into useful
products. Many processes have been discovered by the researchers to crack and
convert the CO2 into fuels, hence completing the fossil fuel cycle. Yet, most of these
advanced processes are requiring a large amount of energy because carbon dioxide is
very stable. Therefore, solar energy which is freely available has been selected as the
major source of energy for the process of CO2 cracking.
