A series of obstacles fell before the onslaught of a Penn State engineering graduate class as they tackled and found solutions to all the barriers preventing development of a hybrid fuel cell automobile using hydrogen fuel cells and battery storage.
“The professors asked the class to solve the problem of hydrogen odorization,” says Jamie Weston, graduate student in energy and geoenvironmental engineering. “We quickly came up with a solution and, took the rest of the course to develop our so
Using photon emissions from individual molecules of silver, researchers at the Georgia Institute of Technology have created what may be the worlds smallest electroluminescent light source.
Believed to be the first demonstration of electroluminescence from individual molecules, the work could lead to new types of nanometer-scale optical interconnects, high-resolution optical microscopy, nanometer-scale lithography and other applications that require very small light sources. And becaus
An enormous source of clean energy is available to us. We see it almost every day. Its just a matter of harnessing it.
The problem with solar energy is that it has not been inexpensive enough in the past. David Kelley, professor of chemistry at Kansas State University, developed a new type of nanoparticle — a tiny chemical compound far too small to be seen with the naked eye — that may reap big dividends in solar power.
Kelleys team is studying the properties and tech
New technology for generating power from coal mining waste was launched by the Federal Minister for Industry, Tourism and Resources, the Hon. Ian Macfarlane, at CSIRO in Brisbane today.
The revolutionary technology has the potential to significantly reduce greenhouse gases and bring big savings to mining companies operating coal mines.
The CSIRO-Liquatech hybrid coal and gas turbine system unveiled at the Queensland Centre for Advanced Technologies will generate electricity from wa
The kerosene that lights your heater or stove might be the same type of fuel powering the nation’s next space vehicle.
Kerosene — almost as common to American life as gasoline — is being considered as a fuel for two main engine candidates for a second generation reusable launch vehicle, now in development by the Space Launch Initiative. The Initiative is NASA’s technology development program to design a complete space transportation system with increased safety and reliability at a lower c
Siemens Automation and Drives (A&D) presents new electronic components in the Delta switches and socket outlets range for the retrofit market in the area of lighting and shutters. The new products include universal dimmer and shutter control inserts, conventional and wireless operator pushbuttons, and a battery-operated wall-mounted transmitter.
The “sys universal dimmer insert” is suitable for all types of lighting to 420 watts/volt-ampere connected load. The dimmer can be easily retrofitt
Photovoltaics is a science that examines light-electricity conversion. Conversion of solar energy carried by photons is transformed by solar cells into direct-current electrical energy. Interest in the use of photovoltaic (PV) solar technologies is growing rapidly, as it will permit the direct production of electricity from solar radiation without any harmful emissions or noise. Rising energy costs, the finite nature of fossil fuels and worries about climate change has renewed interest in making the
Researchers eager to use individual molecules as the components of ultra-small electronic circuits and computers have put a new spin on their ambitious goal.
They take advantage of a hitherto unexploited property of electric currents, called spin, to make molecular devices that operate under new rules. This fledgling form of electronics, called spintronics, could lead to computers that don’t forget anything when their
Two Basque companies, Enerlim and NECESA, have developed a new wind generator, a wind reservoir to make use of wind energy.
This wind reservoir is much lighter than ordinary three-arm wind generators; hence, it is more economical and easier to install. On the other side, the machine is completely modular, as columns, pulleys and plates can be divided in order to make easier the production, transport and installation. The largest piece to be transported and installed is 12 meters long and 2
The power for Hubble’s scientific discoveries comes from solar cells. Designing and constructing Hubble’s first two sets of solar cell arrays constituted a huge technological achievement for the European Space Agency and European industry. After an in-orbit life of more than 8 years, this example of pioneering space technology was this morning (European time) replaced by new, more powerful arrays.
For the last week a dedicated team of engineers, technicians and scientists from the European
