“…Heliostat fields' efficiency is affected by the heliostat design, the field layout, the tracking and control system. In spite of the advanced design concept and high efficiencies, the solar power tower technology still requires more research and development efforts and demonstration to be ready for commercial use [3].…”

“…Heliostat field performance is a function of: cosine efficiency, shadowing and blocking effect, mirror reflectivity, atmospheric transmittance, and receiver spillage [2,3]. It is well known that the heliostat field represents the largest single capital investment in SPT systems; though R&D in technology are needed to improve the field design and reduce the capital cost and to improve the overall efficiency of the power plant [4].…”

Solar Power Tower systems have attracted the worldwide interest since the early 1980s and heliostat fields have been an area for development due to their high cost and important function. This paper presents a mathematical model to design a small heliostat field with 3 dual-axis heliostat units located in Universiti Teknologi PETRONAS, Malaysia. The model mainly relies on the sun position and tower and heliostat geometrical relations, namely, tower height and the ground distance of the concerned heliostats. The heliostat field layout is configured according to radial staggered pattern then varying the tower height and heliostat ground distance to calculate the facing and target angle of each heliostat. TRNSYS software was used to simulate the power output for the proposed heliostat field. The modeled heliostat field could deliver 10 kW for 12.4 m2 reflective area for latitude 4.3̊ N. A solar power tower testing facility will be built according to the design specifications produced in this paper and TRNSYS simulation results are required to estimate the power input to the receiver system for sizing purpose in the future.

“…It can be observed that, almost until after the Second World War, the CO 2 emissions (and the consumption of fossil fuels) were relatively small. After a large growth in the period 1945-1975 (basically, associated to petroleum) and a certain moderation in the following years(1975( - 2000, emissions associated to coal register a strong recovery in the last few years(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008) as a consequence of the massive growth of the consumption of this fuel in China, and in less proportion, in India.…”

Recursos energètics i crisi : la fi de 200 anys irrepetibles

Els recursos de la natura són finits, especialment les energies no renovables, un fet que no sembla que tinguin en compte molts dels responsables polítics i empresarials. L'autor es pregunta si serà possible mantenir el sistema de desenvolupament industrial iniciat ara fa 200 anys, amb l'explotació del carbó i, més tard, del petroli, del gas natural i de l'urani. Aquesta anàlisi es basa en dades de les grans agències de l'energia (l'Energy Information Administration, EIA, del Govern dels Estats Units, i l'Agència Internacional de l'Energia, IEA-AIE, de l'OCDE), com també en altres fonts estadístiques reconegudes a escala internacional, convenientment contrastades i reelaborades. Els resultats contradiuen moltes argumentacions oficials. Mostren que la crisi energètica serà profunda i que es manifestarà ja en la dècada actual: els recursos no s'acabaran immediatament, però l'escassetat de l'oferta davant de l'augment de la demanda qüestionarà el paradigma del creixement continu. Se suggereix que la crisi financera n'ha estat un preludi. La reducció energètica començarà amb el petroli, fet que comportarà la crisi del transport, el fre de les produccions globalitzades i, en darrera instància, la crisi alimentària (també als països desenvolupats!). El canvi climàtic -imparable, segons les tendències analitzades- serà una dificultat afegida a les readaptacions necessàries. Quin paper podria fer Europa en el futur, amb els recursos energètics ja exhaurits?
