New nanotube coating enables novel laser power meter
The U.S. military can now calibrate high-power laser systems, such as those intended to defuse unexploded mines, more quickly and easily thanks to a novel nanotube-coated power measurement device developed at the National Institute of Standards and Technology (NIST). view more (2009-05-11)
Renewable energy wrecks environment
Renewable does not mean green. That is the claim of Jesse Ausubel of the Rockefeller University in New York. Writing in Inderscience's International Journal of Nuclear Governance, Economy and Ecology, Ausubel explains that building enough wind farms, damming enough rivers, and growing enough biomass to meet global energy demands will wreck the... view more...

Is the sky the limit for wind power?
In the future, will wind power tapped by high-flying kites light up New York? A new study by scientists at the Carnegie Institution and California State University identifies New York as a prime location for exploiting high-altitude winds, which globally contain enough energy to meet world demand 100 times over. view more (2009-06-16)
'Grow your own electricity' says City University
A solid oxide fuel cell, placed in the domestic gas boiler, should generate electricity from the gas every time the boiler is activated. The electricity, if not used around the house, could then be sold back into the national grid - running the electricity meter backwards! view more (1998-11-10)
Renaturation of waterbodies does not have to be expensive
The water landscape in many countries has many deficiencies. The ecological consequences of this are poor water quality as well as a deterioration and a shift of the naturally occurring species spectrum. The Fraunhofer Institute for Systems and Innovation Research ISI, Germany, has examined the existing morphological water structure deficiencies... view more... (2002-08-20)

Solar Energy: Electricity Out Of A Helicopter Turbine
The mountains of Armenia seem to have been created for electric power stations working on solar energy. The scientists at the Radio Physical Research Institute have chosen a ground on Aragats mountain, which is 40 km to the west of Yerevan and situated 1750m above sea level. Southern mountain Sun is a good source of cheap energy. It rises 73... view more... (2001-08-24)
New light detector
A novel prototype light meter has been developed by researchers in New York. Published today in the Institute of Physics journal, Measurement Science and Technology, this new retinal flux density meter will provide an affordable tool for measuring light at all levels and might ultimately lead to new standards to improve both energy efficiency and... view more...

University of Nevada professor demonstrates new hydrogen fuel system
Northern Nevada energy consumers can be excused if they have a sense of "sticker shock" when their power bills come due following the holiday season. Or, that they have a feeling of powerlessness as the price of gasoline climbs to $3 per gallon. view more (2007-02-23)
Genetic hearing loss may be reversible without gene therapy

Remarkable new clothing may someday power your iPod
Nanotechnology researchers at the Georgia Institute of Technology are developing a shirt that harvests energy from the wearer's physical motion and converts it into electricity for powering small electronic devices worn by soldiers in the field, hikers and other users. view more (2008-02-14)
Global glacier melt continues
Glaciers around the globe continue to melt at high rates. Tentative figures for the year 2007, of the World Glacier Monitoring Service at the University of Zurich, Switzerland, indicate a further loss of average ice thickness of roughly 0.67 meter water equivalent (m w.e.). Some glaciers in the European Alps lost up to 2.5 m w.e. view more (2009-01-29)
Electricity and gas consumption at a glance
People who want to save energy should always keep an eye on their consumption. The EWE Box offers customers a neat solution: It enables private households to monitor their electricity and gas consumption whenever they want - and save costs thanks to new pricing models. view more (2008-04-09)
PTB Terahertz calibration satisfies US laser manufacturer
Terahertz radiation still lies in a metrological no man's land - a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. view more (2009-11-06)
UCI scientists first to predict air quality impact of small-scale power sources
As California searches for more sources of power, researchers at UC Irvine have created the first scientific method for predicting the impact of small-scale generators on air quality - a tool that could help the state develop environmentally sound policies to regulate and promote their use. view more (2006-08-22)
Continuous electricity cable monitoring now a reality: Greater reliability at reduced cost
In collaboration with KEMA, two postgraduate students from Eindhoven University of Technology have developed a device that continuously monitors cables to localize weak points in distribution networks. Data on weak point development and location enables an electricity company to pre-empt problems by timely intervention. This in turn enhances... view more... (2005-05-09)
