ARC solar thermal building product demonstrates energy savings of 48 per cent

Researchers at the Alberta Research Council Inc. (ARC) have completed a pilot study identifying a more efficient technology to insulate homes, reducing space heating costs for homeowners. Researchers proved by combining direct solar collection and heat storage technology with existing structural insulated panel system (SIPS), energy consumption for space heating could be reduced by 48 per cent.

The study focused on measuring energy consumption during a peak energy load perio

Solid-State Lighting Sources Getting More Energy Efficient and Smart

Rensselaer Researchers Detail Potential for Smart Lighting in Science

“Smart” solid-state light sources now being developed not only have the potential to provide significant energy savings, but also offer new opportunities for applications that go well beyond the lighting provided by conventional incandescent and fluorescent sources, according to E. Fred Schubert and Jong Kyu Kim of Rensselaer Polytechnic Institute.

In an article published May 27, 2005 in the journal S

Engineers develop low-cost, highly sensitive underwater listening device

Ocean-going acoustic sensor array to aid in national security, ocean research efforts

Jason Holmes, a mechanical engineering graduate student at Boston University and guest researcher at Woods Hole Oceanographic Institute, has devised a low-cost, highly sensitive array of underwater ears that is perking up interest in both homeland security and ocean research circles. Holmes’ device — an underwater hydrophone array designed to be towed by a small, autonomous submarine — c

Flexible tactile sensors could help robots work better

A robot’s sensitivity to touch could be vastly improved by an array of polymer-based tactile sensors that has been combined with a robust signal-processing algorithm to classify surface textures. The work, performed by a team of researchers at the University of Illinois at Urbana-Champaign, is an essential step in the development of robots that can identify and manipulate objects in unstructured environments.

“We are developing artificial tactile sensors that will imitate the

NIST method improves timing in oscilloscopes

A new method for correcting common timing errors in high-speed oscilloscopes has been developed by researchers at the National Institute of Standards and Technology (NIST). The method improves the accuracy and clarity of measurements performed in the development and troubleshooting of components for wireless and optical communications, military radar and other technologies.

Oscilloscopes display graphical representations of electrical and optical signals as waves, showing how the

Making the big step from electronics to photonics by modulating a beam of light with electricity

Much of our electronics could soon be replaced by photonics, in which beams of light flitting through microscopic channels on a silicon chip replace electrons in wires. Photonic chips would carry more data, use less power and work smoothly with fiber-optic communications systems. The trick is to get electronics and photonics to talk to each other.Now Cornell University researchers have taken a major step forward in bridging this communication gap by developing a silicon device that allows an el
