Michael Snow : Souffle solaire = Michael Snow : Solar Breath
No full text"This booklet contains a text by the artist along with a letter to him from Louise Déry on the subject of his Solar Breath (Northern Caryatids), executed in 2002. Michael Snow uncovers the links that sometimes grow between what exists and what is perceived, revealing through a consideration of his work various elements that continue to play a role in his art and enrich his relationship to the world. This publication accompanied the exhibition Michael Snow. Windows, presented at the Galerie de l’UQAM from September 9 to October 8, 2005." -- Publisher's website
Design and modelling of SOI-based solar thermoelectric generators
No full textIn this work, solar micro-thermoelectric generators are designed with a lens concentrating solar radiation onto the membrane of a thermoelectric generator (TEG). By focusing solar radiation, the input heat flux increases; leading to an increase in the temperature gradient across the device. Consequently, a significant improvement in the device efficiency can be achieved. The TEG design involves the use of the SOI wafer's device layer as the first thermoelement and aluminum as the second thermoelement. Isolation trenches are also added to the design for electrical insulation. Heat transfer simulations in COMSOL are performed to verify the viability of the proposed system and an analytical model based on energy balance and heat transfer equations is developed to investigate the performance of solar TEGs with varying geometries, lens parameters, and external conditions. It is found that efficiency is improved by increasing both the concentration factor and the absorptance of the TEG membran

All-Weather Snow Machine Driven by Solar Energy
No full text12 S.Technical snowmaking is the only solution to run ski slopes at the beginning and at the end of the winter season if natural snow is missing. However, technical snowmaking has several shortcomings e. g. high water and power consumption. Furthermore, with current snowmaking technology, snow can only be produced below wet-bulb temperatures of approx. -2.5 °C for compressed air and water guns or below approx. -4 °C for fan guns. This paper presents the concept of a snow machine which can be driven by renewable energy sources, able to produce high quality snow at temperatures above 0 °C, in all-weather conditions, and even in high summer season. The proprietary technology is based on a steam jet ejector chiller (SJEC) and uses the triple point of water. The thermal energy for the ejector can be provided by solar collectors or by a biomass steam boiler. Water is the only working fluid in the entire refrigeration system, which guarantees an ecologically friendly concept for the snow supply. Within the paper, the first operational experiences of the prototype as well as performance figures are presented. Furthermore, a concept for the solar circuit of a solar-assisted snow machine is presented. Subsequently, the system design and system performance of a solar-assisted machine will be evaluated for different scenarios. The evaluation is based on simulation results gathered with a model based on mass and energy balances
