Power and Electrical Engineering

This topic covers issues related to energy generation, conversion, transportation and consumption and how the industry is addressing the challenge of energy efficiency in general.

innovations-report provides in-depth and informative reports and articles on subjects ranging from wind energy, fuel cell technology, solar energy, geothermal energy, petroleum, gas, nuclear engineering, alternative energy and energy efficiency to fusion, hydrogen and superconductor technologies.

Improving the efficiency of hydropower stations

Hydroelectric power provides 16 per cent of Europe’s electricity, but most of the plants and their turbines were designed many years ago. By redesigning the runner – the propeller-like component that transfers energy from the water to the drive shaft in the turbine – EUREKA project FLINDT enables operators to harness more power from their turbines.

According to Professor François Avellan, Director of the Swiss main project partner, Laboratoire de Machines Hydrauliques de l’ EPFL, Ecole poly

Hydrogen vehicle won’t be viable soon, study says

Even with aggressive research, the hydrogen fuel-cell vehicle will not be better than the diesel hybrid (a vehicle powered by a conventional engine supplemented by an electric motor) in terms of total energy use and greenhouse gas emissions by 2020, says a study recently released by the Laboratory for Energy and the Environment (LFEE).

And while hybrid vehicles are already appearing on the roads, adoption of the hydrogen-based vehicle will require major infrastructure changes to make compres

Commission presents the state of play of ITER project

Today in Brussels European Research Commissioner Philippe Busquin presented the status of the international negotiations relating to the ITER (International Thermonuclear Experimental Reactor) research project on nuclear fusion energy.

A significant step has been achieved with the entry into negotiations of the People’s Republic of China and the comeback of the United States of America. Participants to the negotiations will have to identify the ITER site from among the four current c

Tiny computing machine fueled by DNA

The device was awarded the Guinness World Record for “smallest biological computing device”

Fifty years after the discovery of the structure of DNA, a new use has been found for this celebrated molecule: fuel for molecular computation systems. The research, conducted by scientists at the Weizmann Institute of Science, will appear in this week’s issue of Proceedings of the National Academy of Sciences USA (PNAS).

Whether plugged in or battery powered, computers need energ

Self-powered appliances–no batteries needed

Appliances that need no cables or batteries but operate purely on power generated from their surrounding vibrations could save manufacturers and consumers large sums of money, according to scientists at the University of Southampton.

Professor Neil White and his colleagues at the University’s Department of Electronics and Computer Science realised three years ago that sensors were being used in increasingly diverse application areas where physical connections to the outside world were d

It pays to convert food processing wastewater to energy source

In laboratory tests, Penn State environmental engineers have shown that wastewater from a Pennsylvania confectioner, apple processor, and potato chip maker can produce hydrogen gas worth $80,000 a year or more. Steven Van Ginkel, doctoral candidate, and Dr. Sang-Eun Oh, postdoctoral researcher in environmental engineering, conducted the tests.

“In addition to hydrogen, which can be used as a fuel and industrial feedstock, methane, the main component of natural gas, can be generated from the
