Clean Coal Construction Cleared
Clean coal has some support — you might call it a change of hearth. But in Indiana, the utility regulatory commission recently approved a Duke Energy Indiana 630 MW Integrated Gasification Combined Cycle (IGCC) power plant. Regulatory approval was eased because IGCC is one of the cleanest ways to burn coal. What forms of energy do you think we should pursue?

Drought Threatens Hydro Power
Drought in North America is drastically reducing some lake levels and hydro power capacity. T&D World describes how one utility copes with lower lake levels by upgrading transmission lines to import power. Expect other utilities to follow or come up with other creative solutions for the problem of shrinking lakes.

Optical Connector Couples Cores
Industry journal Optics Express reports on a promising development that may replace copper wires with a new type of optical connectors for communication among processor cores. The optical connector is called a silicon Mach-Zehnder electro-optic modulator. Researchers claim it is many times smaller than previously produced devices.

RFID Prevents Accidents
RFID has been used extensively to track parts, but the technology has many other manufacturing applications. This white paper, presented at the World Batch Forum, is titled RFID Based Solution for Asset Tracking, Location Awareness and Safety Management. It tells how RFID can control employee access to hazardous locations.

See the Light
Light sensors are used in applications including optical-absorption spectroscopy, infrared detection for thermography, and two-color pyrometry. A major problem found when applying light sensors is eliminating influences from DC or very-low-frequency background light. This EDN article shows how to eliminate interference and measure the correct parameters.

Fuel Cells Go Nano
This Small Times article describes how Nanotechnology is being used in fuel cells to significantly reduce size and costs. Initial designs improve conventional methanol polymer electrolyte membrane fuel-cell technology with Nanostructured catalytic layers and MEMS-based micro reformers. Other prototypes use designed molecules that self-assemble into membranes with targeted properties.

Car Catalyst Cuts Costs
An automotive catalyst developed by Mazda uses single-nanotechnology to reduce required amounts of platinum and palladium by 70-90%while maintaining performance and durability. Technology News Daily reports that single-nanotechnology uses even smaller particles than Nanotechnology, which greatly increases the catalyst precious metal surface area.
