Carnegie Mellon researcher leads team working to create methanol fuel cell

Tiny fuel cells may provide power to many consumer goods

Carnegie Mellon University’s Prashant Kumta will discuss his novel methanol-powered fuel cell research from 8 to 9:30 a.m., Feb. 18, during the annual meeting of the American Association for the Advancement of Science at the Renaissance Grand Hotel in St. Louis, Mo.

Kumta, a professor of materials science and biomedical engineering, is developing microscale fuel cells that use methanol instead of expensiv

SensorNet prototype system in boot camp at Fort Bragg

Fort Bragg could be the model for the nation when it comes to protecting the public through a network that integrates a 911 dispatch system with sensors, alarms and video surveillance.

Oak Ridge National Laboratory’s SensorNet, a collection of systems for the detection, identification and assessment of chemical, biological, radiological and nuclear threats, has been installed as part of a project with the Fort Bragg Directorate of Emergency Services. The military base, locat

MIT powers up new battery for hybrid cars

Researchers at MIT have developed a new type of lithium battery that could become a cheaper alternative to the batteries that now power hybrid electric cars.

Until now, lithium batteries have not had the rapid charging capability or safety level needed for use in cars. Hybrid cars now run on nickel metal hydride batteries, which power an electric motor and can rapidly recharge while the car is decelerating or standing still.

But lithium nickel manganese oxide, descri

As Much Hot Water As Your Need Or The Sun In Trap

A unique solar collector was developed by specialists of the Moscow “ALTEN” company under the guidance of Boris Kazandzhan, Professor, Doctor of Science (Engineering), Moscow Power Engineering Institute. Originality of the novelty lies in its extremely high efficiency. The collector not only manages to entrap the heat of solar beams falling on its surface, but also to utilize it to a great extent for direct purpose – for water heating.

Evidently, the idea of water heating in sunlight is

UF engineer develops tiny, easily mass-produced motion sensor

A University of Florida engineer is the latest researcher to design a tiny, easy-to-manufacture motion sensor, a development that could help popularize the sensors as standard equipment in personal electronics, medical devices and other applications.

The sensor, which measures about 3 square millimeters or one-tenth of an inch, is not the smallest motion sensor ever invented. But it is extremely sensitive, draws only a tiny amount of electrical power and — most important – is one of a

Titania nanotubes create potentially efficient solar cells

A solar cell, made of titania nanotubes and natural dye, may be the answer to making solar electricity production cost-effective, according to a Penn State researcher.

“Solar cell technology has not changed very much over time and is still predominantly silicon solar cells,” says Dr. Craig Grimes, professor of electrical engineering and materials science and engineering. “It takes a great deal of energy, 5 gigajoules per square meter, to make silicon solar cells. It can be ar
