Electricity supply problems solved with wind-powered energy

The University of the Basque Country, IBERDROLA (an electricity utility supplying the Basque Country), the enterprises INGETEAM and INDAR and innovative energies company EHN have participated jointly in this research project. The project has put forward an innovative use of wind-sourced energy to control fluctuations on the grid. The research site where measurements were made was the Salajones wind park in Sanguesa (Navarre).

In recent years the electricity utilities have shown much greater

Space Station crew, scientists fine-tune zeolite experiment

The Zeolite Crystal Growth (ZCG) experiment got off to a successful start this week aboard the International Space Station.

Hard as a rock, yet able to absorb liquids and gases like a sponge, zeolites form the backbone of the chemical processes industry. Virtually all the world’s gasoline is produced or upgraded using zeolites. Improving zeolites could make gasoline production more efficient or lead to ways of storing clean-burning hydrogen for fuel. Zeolites can also be applied to

Energy network launches international web survey

A European website designed to stimulate informed debate on future energy sources this week launches a multi-lingual survey to gauge public attitudes to, and knowledge of, crucial energy issues.

The INTUSER website (www.intuser.net) is a new on-line forum for both the general public and energy experts to communicate about energy issues – from nuclear power and global warming to alternative energy sources such as solar and wave power.

Renewable energy expert Robin Saunders, of the Un

Silicon transistors will encounter pressure from nanoelectronics

The future of nanoelectronics looks promising. Built with nanotubes and various self-assembling molecular structures, this technology may revolutionize the electronic world by replacing the silicon transistor in approximately ten years.

Chemically synthesized nano building blocks are expected to replace semiconductor logic and memory devices and target niche applications over the next decade.

“In 20 to 50 years, we will likely see wide-ranging use of self-assembly,” says Technical I

An unexpected discovery could yield a full spectrum solar cell

Researchers in the Materials Sciences Division (MSD) of Lawrence Berkeley National Laboratory, working with crystal-growing teams at Cornell University and Japan’s Ritsumeikan University, have learned that the band gap of the semiconductor indium nitride is not 2 electron volts (2 eV) as previously thought, but instead is a much lower 0.7 eV.

The serendipitous discovery means that a single system of alloys incorporating indium, gallium, and nitrogen can convert virtually the full spectru

Alberta Research Council reaches major milestone in the development of micro fuel cell technology

A first in Canada, the Alberta Research Council (ARC) reached a milestone in the technical development of its own version of solid oxide fuel cell (SOFC) technology. ARC scientists are developing a proprietary micro solid oxide fuel cell (µ-SOFC) source of energy for small-scale portable applications such as laptops or personal digital assistants (PDAs).

“This is an important milestone as we pursue our strategic initiative in fuel cell technologies,” says John Zhou, manager, Advanced Materi
