Solar Water Disinfection Studies With Supported TiO₂ and Polymer-Supported Ru(II) Sensitizer in a Compound Parabolic Collector
Solar water disinfection was performed using TiO2 and a Ru(II) complex as fixed catalysts located in a compound parabolic collector photoreactor. Studies were performed in the laboratory as well as at...

Solar Concentrating Systems Using Small Mirror Arrays
The cost of solar tower power plants is dominated by the heliostat field making up roughly 50% of investment costs. Classical heliostat design is dominated by mirrors brought into position by steel st...

A1-kW small horizontal-axis wind turbine “Airdolphin,” capable of high windoperation up to 50 m/s without pitch control system, isnow under global round robin tests. The present paper reportsa series of technical approach including design/analysis, track tests, andfield tests conducted in support to the design process. Onewindy site “Erimo” and one offshore site “Fukushima” were chosen.For example, at “Erimo,” a record of one-day generation was8.831 kWh on November 13, 2006 (day-averaged wind speed; 11.8m/s) with 36.8% of capacity factor. An operation data underan attack of typhoon with 50 m/s maximum wind speeddemonstrated the technical concepts of high wind operation and safety.A new term “capatureability” as an indicator of WT performancewas proposed.
