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.

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

Battery power

Consumer demand for lighter, more powerful handheld devices such as laptop computers and mobile phones is growing year on year. The EUREKA project 3D STRUCTURES has addressed one of the key requirements – cheaper and lighter batteries that last longer.

French lead partner SCPS (Societé de Conseil et de Prospective Scientifique S.A.) has developed a new kind of conductive metallic foam capable of replacing heavy metallic parts. A cylindrical block of foam is immersed in an aqueous solution t

Jefferson Lab technology takes center stage in the construction of SNS accelerator

Jefferson Lab is once again taking center stage, as Lab scientists, engineers and technicians mobilize to provide 81 niobium cavities for 23 cryomodules for the Spallation Neutron Source under construction in Oak Ridge, Tennessee

Thermos bottles usually don’t weigh nearly five tons or measure almost 26 feet end-to-end. But these aren’t run-of-the-mill containers for soup or coffee. Rather, they’re the complex, state-of-the-art supercooled components in which particle beams are

Jefferson Lab experiment generates THz radiation 20,000 times brighter than anyone else

An experiment conducted by the Department of Energy’s Jefferson Lab generates THz radiation 20,000 times brighter than anyone else; breakthrough lights way for application development

Experiment generates THz radiation 20,000 times brighter than anyone else; breakthrough lights way for application development

An experiment conducted with Jefferson Lab’s Free-Electron Laser has shown how to make a highly useful form of light — called terahertz radiation — 20,000 times brigh

Kaixo, classifier of photoelectric cells

Currently there is great talk of renewable energies and, amongst these solar energy is highly important. In order to harness and utilise this form of energy there are many technologies available of which one is solar panels. These panels are made up of photoelectric cells (the 80-100 little square units in any one panel).

Photoelectric cells are classified according to the power they produce, given that total power production of any panel can be limited by just one photoelectric cell of lowe
