Seven configurations of Photovoltaic (PV) energy conversion systems were investigated and their performances compared to direct solar PV conversion. The systems involved use of filters, concentrator lens, fiber transport, and direct use of PV. Transmission of concentrated light onto PV cell...

Evidence on global climate change, being caused primarily by rising levels of greenhouse gases in the atmosphere, is perceived as fairly conclusive. It is generally attributed to the enhanced greenhouse effect, resulting from higher levels of trapped heat radiation by increasing atmospheric...

The field performance of thermal energy storage (TES) systems was compared to the “simulated field performance” of conventional systems. Field data for several TES sites, provided by the Electric Power Research Institute (EPRI), were analysed using a “mean-day” and “peak-day”...
