This paper presents a summary of the mechanical features and the medium term operating experience from three small horizontal axis wind energy conversion systems covering a range of 500 to 5000 Watt, intented for rural and isolated communities. These turbines have a new regulator which reduces...

Daily irradiation images over Spain – area that embraces a highly heterogeneous landscape, climatic conditions and relief – are calculated from the down-welling surface short-wave radiation flux (DSSF) product derived from the MSG SEVIRI images. Their analysis and validation is carried out...

To assess the effects of mass transfer and hydrogen pressure on the oil yield and quality from cellulosic biomass, fixed-bed pyrolysis (atmospheric pressure) and hydropyrolysis experiments at temperatures between 400 and 650°C have been conducted on sunflower bagasse and pure cellulose. The...
