Moving Toward a Carbon-based Solar Cell

To make large sheets of carbon available for light collection, Indiana University Bloomington chemists have attached what amounts to a 3D bramble patch to each side of the carbon sheet. The scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, which is a first.

LED Bulb Replaces Incandescent Bulb

A 40-watt GE Energy Smart® LED bulb from GE Lighting (Cleveland, OH) will be available later this year or early 2011. The new LED bulb is expected to consume only 9 watts, provide a 77 percent energy savings, and produce nearly the same light output as a 40-watt incandescent bulb - while lasting more than 25 times as long.

LED Edge-Lighting Solution

Global Lighting Technologies (GLT), Inc. (Brecksville, OH) now offers LED edge-lighting solutions that focus light into a high-performance backlight, or light guide. Because the LEDs are located on the edge of the light guide, there is better optical control for color and uniformity, fewer LEDs, better repeatability, and the thinnest possible lighting solution.

Electrochemical Double Layer Capacitors

New large cell prismatic electrochemical double layer capacitors (EDLC) from Ioxus (Oneonta, NY) are for transportation and utility applications and are lower in cost for the overall system design. The 1,000-, 3,000-, and 5,000-Farad (F) ultracapacitors are smaller in size, with increased energy and power density, compared to products of other industry players.
