Coastal tourism: the response of Indian Ocean island tourism destinations to climate change
No full textThis research examines tourism within developing island states in the Indian Ocean that will be at extreme risk from the impacts of climate change. Many have a high economic reliance upon tourism and yet will be adversely affected by both higher sea levels and raised water temperatures. However, many developing islands utilise tourism as a vector for economic growth and ironically they too tend to be some of the first destinations to observe possible impacts of climate change like the disappearance of beaches and the greater intensity of storms. Destinations in the developing world are extremely concerned that tourists from developed countries will reduce the number of long haul flights they take to ameliorate their carbon footprint
Análisis energético de una planta CSP basada en CO2 supercrítico aplicada en Colombia
No full textThermo-solar energy technology offers a promising potential for future sustainable power generation, especially those ones based en central tower receivers which can achieve higher temperatures for a higher thermal efficiency. Currently, these power plants still have obstacles and limitations which difficult its competition against fossil fuel based systems. For this reason, more efficient thermodynamic cycles are essential for the future of this installations, since this reduces the Levelized Cost of Electricity (LCOE) and facilitates the adoption of these new production methods. In the present work, a recompression cycle based on supercritical CO2 is adapted for its implementation in CSP plan with a central tower receiver exposed to the weather conditions in the Guajira region, in northern Colombia. The plant operation is evaluated according to the first law of thermodynamics and theoretical results obtained show the performance, thermal efficiency, annual energy produced and its availability during 3 years. For start, they indicate an improvement in the amount of energy per area produced and present the critical components which behaviour can be adapted for the production optimizationIngeniero MecánicoPregrad
