Wind Tower Uses Sun’s Heat To Generate Electricity

Wind generators are great for producing electricity But lack of wind isn’t an insurmountable problem, according to a group of UA Engineering students. They’ve been experimenting with a design that doesn’t depend on the vagaries of natural wind. Instead, their design produces its own airflow by trapping heat from the sun and then allowing the heated air to escape through a chimney-like tower to an area of lower pressure and cooler a

Repeatable low-breakdown voltage antifuses enabled through a Sandia-developed dielectric thin film

Researchers at Sandia National Laboratories have developed an inexpensive, reliable and easy-to-manufacture class of dielectric films that have the capability of enabling programmable antifuses on integrated circuits (IC) at less cost and using easier-to-manufacture methods.

The new Sandia films enable single-mask level sub 5 Volt write antifuses that are compatible with leading-edge IC specifications.

Antifuses are nonvolatile, one-time programmable memories fa

Siemens to Supply 17 Wind Turbines for Repowering Projects in Germany

After the boom for new wind turbines in Germany in the past years, the repowering of these turbines gains more and more importance today. In the future, larger units will replace the smaller and older wind turbines, especially at sites with strong wind conditions. Siemens Power Generation (PG) is to supply a total of 17 wind energy turbines for three repowering projects in Germany. Of these, seven wind turbines will be for the Marienkoog project, and seven will be for the Norderhof Wind Park in t

Potential Energy – fuelling the nuclear energy debate

With the threat of climate change and decreasing supplies of fossil fuels, the UK is going to have to find new ways to fuel our future to avoid an energy crisis. But with so much information out there, how can ordinary people find out more about what options there are? To help tackle this, the Institute of Physics today launches Potential Energy, a web log where three journalists will investigate the science of nuclear new-build for ten weeks.

The government white paper on the future possib

Rising price of oil highlights affordable energy alternatives

The Earth Institute at Columbia University — With oil prices reaching near near-record highs in recent weeks, calls have grown louder for the U.S. to develop new sources of affordable, domestic energy. Work by experts from The Earth Institute at Columbia University suggests that relatively low-cost alternatives already exist to meet the country’s’ growing energy demand that would at the same time reduce the need to rely on oil supplies from the Middle East and Latin America.

VTT to Improve Information Security of European Electricity Distribution

Safe distribution of electricity has been set as objective

Multifarious intentional and unintentional situations – ranging from short circuits and human errors to hackers and terrorists exploiting security vulnerabilities in control systems – can paralyse Large Critical Complex Infrastructures (LCCIs). VTT is playing a key role in an EU project aimed at protecting the critical infrastructure of European society. The project focuses on, e.g. preventing information security threa
