DOE outlines research needed to improve solar energy technologies

To help achieve the Bush Administration’s goal of increased use of solar and other renewable forms of energy, the Department of Energy’s (DOE) Office of Science has released a report describing the basic research needed to produce “revolutionary progress in bringing solar energy to its full potential in the energy marketplace.” The report resulted from a workshop of 200 scientists held earlier this year.

“The tax credits contained in the historic energy bill signed by President Bush

Technology holds promise for infrared camera

New technology developed at Northwestern University has the potential for broad application in the detection of terrorist activities such as missile attacks on U.S. troops. Scientists at the Center for Quantum Devices (CQD) have demonstrated, for the first time, uncooled infrared imaging using type-II superlattice technology. This significant development could lead to smaller, faster and less expensive hand-held infrared imaging devices.

High-speed infrared (IR) imagers are capable of se

Fastnet yacht runs faster with space technology

Space has come down to Earth for this week’s legendary Fastnet regatta. Competitor Marc Thiercelin’s 20-metre Pro-Form yacht boasts lighter batteries, more efficient solar cells and advanced energy management systems – all spin-offs from Europe’s space programmes.

On Sunday 7 August 283 boats took off from Cowes in the Rolex Fastnet 2005 race, sailing along the south coast of England before crossing the Irish Sea to round the Fastnet Rock off Ireland’s south we

Cleaner transport through engine ‘neurosurgery’ and recycled cooking oil

The next generation of motor vehicles could be powered by engines that are cleaner, greener and smarter, thanks to research at two South West universities.

Engineers at the University of Bath are carrying our research described as being like ‘neurosurgery on diesel engines’ to find ways of making them even more efficient than their petrol-driven equivalents.

Meanwhile, researchers at the University of the West of England are experimenting with the production of fuel ma

Sensor could detect concealed weapons without X-rays

A new sensor being patented by Ohio State University could be used to detect concealed weapons or help pilots see better through rain and fog.

Unlike X-ray machines or radar instruments, the sensor doesn’t have to generate a signal to detect objects – it spots them based on how brightly they reflect the natural radiation that is all around us every day.

There is always a certain amount of radiation – light, heat, and even microwaves – in the environment. Every objec

Italian research opens new possibilities for the hydrogen production and for the purification of polluted gases

The next issue of Science will report a study that explains the mechanism for oxygen release by cerium oxide. This material is an important catalyst that favors many fundamental reactions that have profound implications for energy storage and environmental issues. These reactions include, for example, the purification of polluted gases and the production of hydrogen as new energy vector for fuel cells. The present study could inspire the design of new efficient catalysts for producing a large va
