The Emerging Power of Microgrids

by GLOBE Foundation  (Jul. 3, 2014)

Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions. But in recent years the system’s shortcomings have become increasingly ...

Break It Down, Build It Up - Sustainable Science Has Roots in ASTM Standards Development

by ASTM International  (Jun. 30, 2014)

It was back in the 1980s,” Richard Wool, Ph.D., recalls. “A lot of waste management sites were running out of space. Barges full of garbage were plowing up and down the East Coast with no place to dock. The idea of having biodegradable plastics would address a number of issues like getting rid of the trash and cleaning up marine waste, ...

5 Reasons to Perform a Consequence Modeling Analysis for Your Facility

by BREEZE Software and Data / Trinity Consultants  (Apr. 23, 2014)

The potential for accidental release of toxic chemicals to the environment is a daily threat for many industrial facilities and plants. These releases can occur very suddenly and unexpectedly, putting employees and the public at risk of injury or death, and the surrounding environment at risk of damage or destruction. A consequence modeling ...

2nd Generation Wind Turbines

by SolarPanels4u  (Jan. 16, 2014)

2nd generation wind turbines are better, more effective, than its predecessor, and succeed in generating more electricity with smaller wind volumes. These wind turbines incorporate two newer technologies, that make them more efficient. Self starting vertical blades and magnetically suspended bearings, which makes them superior to any other. The ...

Influence of exogenous and endogenous factors on the exergy analysis of 3–column array wind farm

by Inderscience Publishers  (Feb. 28, 2014)

Influence of exogenous and endogenous factors on the exergy analysis of 3 column array wind farm for two different layouts are highlighted in this paper. Nine turbines were placed in two different layouts to analyse the influence of exogenous factors such as wind velocity, wind direction, wind distribution and distance between turbines. Endogenous ...

Wind power prefeasibility study for agricultural applications in Kerman, Iran: a case study

by Inderscience Publishers  (Mar. 6, 2014)

In the present paper, wind characteristics have been analysed for three agricultural sectors in Kerman (30°15'N,56°58'E), Iran. Wind data collected from three synoptic stations for the period of July 2006 to June 2011 at the height of 40 m has been used to study the monthly and annual wind energy potential. Two statistical methods (Meteorological ...

Sea wave propagation from offshore to Maputo's coast. Application to longshore sediment transport assessment

by IWA Publishing  (Jun. 25, 2014)

This study aims to characterize the wave climate near the coastal region of Maputo (Mozambique), and to provide a first assessment of the sediment transport load in this area. A time-series of 13 years' worth of offshore wave data, obtained from reanalysis products, was propagated to the coast. Wave propagation was performed using Linear ...

Hourly NOx concentrations and wind direction in the vicinity of a street intersection

by Inderscience Publishers  (Oct. 13, 2012)

This study relates NOxconcentrations and wind (speed and direction) measured inside an asymmetric street canyon, with ambient wind. The monitoring site is located near a street intersection. The wind measured at the domestic airport located in the city, near the coast, has been considered as ambient wind. Wind direction at the monitoring site ...

The Developing Role of Permanent Magnets in Renewable Energy

by Stanford Magnets  (Jun. 25, 2014)

The developing role of Permanent Magnets in renewable energy production along with the environmental protection is a very worthy topic. An upright permanent magnet should produce a high magnetic field with a near to the ground mass, and should be constant against the inspirations which would demagnetize it. The desirable properties of such magnets ...

ADMS 5 Buildings Validation Lee Power Plant Wind Tunnel Study

by Cambridge Environmental Research Consultants (CERC)  (Jun. 15, 2013)

1 Introduction The Lee Power Plant wind tunnel study1 [1] featured releases from steam boiler stacks with a common height of 64.8 m affected by a building tier with a height of 42.6 m. The world's largest fluid modelling study chamber at Monash University in Australia was used for these experiments (see plan view in Figure 1). Stable ...
