Power and Electrical Engineering

In the June 2004 issue of Mechanical Engineering, a publication of ASME, the magazine reports on a fuel cell that cleans domestic wastewater while producing electrical energy.

This new type of microbial fuel cell, which is in the early stages of research at Pennsylvania State University, takes the high concentration of organic matter found in wastewater and coverts it to energy. “Where a typical fuel cell runs on hydrogen, a microbial fuel cell relies in the anaerobic oxidation of organic ma

Marriage of quantum well, quantum dots could produce white light

A wireless nanodevice that functions like a fluorescent light – but potentially far more efficiently – has been developed in a joint project between the National Nuclear Security Administration’s Los Alamos and Sandia national laboratories.
The experimental success, reported in the June 10 issue of Nature, efficiently causes nanocrystals to emit light when placed on top of a nearby energy source, eliminating the ne

The University of North Dakota (UND) Energy & Environmental Research Center (EERC) has begun a demonstration project to determine the economic viability and environmental advantage of generating power using a 30-kilowatt microturbine fueled with sour (impure) natural gas often produced along with oil.

The project is being demonstrated at an oil field in Newburg, North Dakota, operated by Amerada Hess Corporation, an international petroleum company with 461 active wells in North Dakota. A Cap

“Nanodumbells” – gold-tipped nanocrystals which can be used as highly-efficient building blocks for devices in the emerging nanotechnology revolution – have been developed by researchers at the Hebrew University of Jerusalem.

The technology, developed by a research group headed by Prof. Uri Banin of the Department of Physical Chemistry and the Center for Nanoscience and Nanotechnology of the Hebrew University, is described in an article in the current issue of Science magazine.

By carving specks of single crystal silicon from a bulk wafer and casting them onto sheets of plastic, scientists at the University of Illinois at Urbana-Champaign have demonstrated a route to ultrahigh performance, mechanically flexible thin-film transistors. The process could enable new applications in consumer electronics – such as inexpensive wall-to-wall displays and intelligent but disposable radio frequency identification tags – and could even be used in applications that require significant

This is the PVNET Roadmap for European Research and Development for Photovoltaics, a network, which brought together representatives of relevant research and development (R&D) and production areas in photovoltaics. Their main task was to stimulate communication within the whole PV community by organising expert meetings, workshops and symposia, and disseminating the information gathered therein. This Thematic Network was carried out in the framework of the specific research and technological develop
