Solar energy dissipation and temperature control by water and plants

by Inderscience Publishers  (Feb. 25, 2011)

Ecosystems use solar energy for self-organisation and cool themselves by exporting entropy to the atmosphere as heat. These energy transformations are achieved through evapotranspiration, with plants as 'heat valves'. In this study, the dissipative process is demonstrated at sites in the Czech Republic and Belgium, using landscape temperature data ...

Development of optimum solar irradiation energy model for Iran

by Inderscience Publishers  (Mar. 19, 2009)

In this article, an optimal model for calculating the total solar irradiation is represented for Iran. Eight irradiation models are analysed based on the meteorology information of 22 synoptic stations. Afterwards, accuracy of these methods is compared using standard error criteria. Hence, Daneshyar and Modified Daneshyar are introduced as the ...

Integrated solar and wind energy powers oil recovery system

by USEPA - Technology Innovation and Field Services Division (TIFSD)  (Jul. 1, 2008)

Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) ...

Mobile systems provide solar energy in northern climates

by USEPA - Technology Innovation and Field Services Division (TIFSD)  (Jul. 1, 2008)

The Department of Transportation for Alberta, Canada, is examining innovative strategies to resolve environmental issues in remote areas of the province. Portable units for harnessing solar energy have been demonstrated over the past five years as a viable method for generating the electricity needed to drive remediation systems at several sites ...

Energy and exergy efficiencies of a solar box-cooker

by Inderscience Publishers  (Nov. 15, 2004)

A simple and low-cost box-type solar cooker (SBC) was designed and tested. The energy and exergy efficiencies of the SBC were experimentally evaluated. The energy output of the SBC ranges from 2.1 to 61.7 kJ, whereas the exergy output ranges from 0.4 to 6.2 kJ during the same time interval. The average daily energy and exergy outputs of the SBC ...
