In the context of achieving a national set target of 60 GW by 2022, a study was carried out in Kayathar, Tuticorin district, Tamil Nadu, India on noise propagation from wind turbines. Acoustic and non-acoustic parameters were measured according to IEC 61400-11 at wind speeds of 4-13 and 0.7-8.6 m/s. The onsite measurements were compared with ISO 9613-2; this showed a difference of ± 5 dB(A) for every increment in the distance. An equation was derived to obtain sound pressure level (dB(A)) at the base of the tower for wind turbines at varying distance of measurement.Keywords

This work deals with the performance of a microbial fuel cell, focusing on the electrocatalytic activity of selected cathodes constructed by coating nanocomposites over graphite felt under neutral pH in a doublechamber configuration using paper-recycled waste water as a typical electrolyte. Among all cathodes, iron phthalocyanine (FePc) combined multiwalled carbon nanotubes (MWCNT) shows the highest power density (9.34 W/m2) compared to other two catalysts, FePc/Ketjan black (4.68 W/m2) and MWCNT (2.9 W/m2) under similar conditions of using a reference platinum/carbon (Pt/C) loading of 0.5 mg/cm2. The morphology of these catalyst coated electrodes was characterized by scanning electron microscopy. Their electrocatalytic activities were examined using cyclic voltammetry. This work provides an appropriate alternative for cathode catalysts in treatment as well as in electricity production as demonstrated by the high power density of the above catalysts compared to that using precious Pt metal catalyst in microbial fuel cells.Keywords
