The emission of carbon dioxide (CO 2 ) and other pollutants which result from burning fossil fuels has been identified as the major contributor to global warming and climate change. However, for the immediate term, over the next 10 -20 years at least, the world will continue to rely on fossil fuels as the source of primary energy. The challenge for the fossil fuel industry is to find cost-effective solutions that will reduce the release of CO 2 and other pollutants into the atmosphere.The focus of this paper is on the ability to treat the exhaust gas from fossil fuel power plants in order to capture and store the CO 2 and remove other pollutants such as SO x and NO x which are released in the atmosphere.In summary, capture/separation costs represent the largest financial impediment for these types of plants. Hence, efficient, cost-effective capture/separation technologies will need to be developed to allow their large-scale use.
In comparison with the Stirling machine, the thermoelectric generator (TEG), based on the Seebeck effect, allows the direct transformation of thermal energy into electric energy. TEG has no moving parts and it does not pollute. Unfortunately, its performance is much under the Stirling machine's efficiency, the main disadvantage being the low voltage of TEG. An important feature of TEG usage in space applications is that the heat exhausting is made only by radiation. This paper argues the use of TEG's pulsed operation, the main effect being an increased working voltage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
