For the future hydrogen economy, a tiny, self-powered sensor

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

Here comes the sun: New solutions for world’s energy woes

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

Strong Focus on Energy at CSD-14

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 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
