The well-known answer to this question is that it stops being a motor and becomes a generator. Instead of using electricity to turn a propeller and drive the…
As gas prices soar and greenhouse gases continue to blanket the atmosphere, the need for a clean, safe and cheap source of energy has never seemed more pressing.
Scientists have long worked to meet that need, exploring alternative energy technologies such as wind and solar power. But, after decades of quiet progress, the spotlight is now on another potentially inexhaustible energy source.
Seven countries signed an agreement in Brussels last week (May 24) to launch cons
Hydrogen has been called “the fuel of the future.” But the gas is invisible, odorless and explosive at high concentrations, posing a safety problem for hydrogen-powered cars, filling stations and other aspects of the so-called hydrogen economy.
Now, a team of more than a dozen University of Florida engineering faculty and graduate students has found a way to jump that hurdle: a tiny, inexpensive sensor device that can detect hydrogen leaks and sound the alarm by wireless com
FSU research could bring electricity to millions who now have none at all
The number is staggering: Approximately 2 billion of the world’s people — nearly one-third of the human population — have no access to electricity. Consequently, they do without many of the amenities that people in the developed world take for granted — everything from air conditioning and refrigeration to television, indoor lighting, and pumps that supply drinking water. And without electricity
Human Security and Institutions also Crucial
At the 14th Session of the Commission on Sustainable Development (CSD-14) that took place in New York from 1 to 12 May 2006, the energy theme occupied the top position in the discussions. The pressing need for debate and action – with oil prices nearly tripling in the last two years – turned the spotlight on this UN event. Politicians and energy experts used this platform to address the energy challenge and accompanying security concerns
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
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
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
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
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.

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
Engineers at the UCLA Henry Samueli School of Engineering and Applied Science are announcing a critical new breakthrough in semiconductor spin-wave research.
UCLA Engineering adjunct professor Mary Mehrnoosh Eshaghian-Wilner, researcher Alexander Khitun and professor Kang Wang have created three novel nanoscale computational architectures using a technology they pioneered called “spin-wave buses” as the mechanism for interconnection. The three nanoscale architectures are not only power
