Thin Film Absorbers for Solar Cells

Oregon State University researchers have made an important breakthrough in the use of continuous flow microreactors to produce thin film absorbers for solar cells - an innovative technology that could significantly reduce the cost of solar energy devices and reduce material waste.

Should broadband providers be required to provide network neutrality?

This week's question concerns "net neutrality" -- providing equal treatment to all Internet traffic flowing over networks. Supporters of net neutrality argue that a policy is necessary to prevent providers from favoring or discriminating against certain Web sites and online services; however, broadband providers contend that they should be able to sell premium services and manage their systems to prevent certain applications from sucking up capacity.

What do you think? Should broadband providers be required to provide network neutrality?

Paving the Way for Electromobility

Fraunhofer researchers are engineering wheel hub motors, which are integrated into a car's wheels, and could become the accepted drive concept for electric vehicles. The scientists are testing these and several other components on the "Frecc0," their demonstration vehicle.

LED Power Supply With Dimming Control

New from Power Partners (Hudson, MA) is the PIL40U-C LED power supply, which provides 40W in a compact, IP66 wateproof case. Highly efficient (up to 88%) and with a high power factor rating (0.99 at 110VAC), the supply also includes comprehensive overvoltage, overload, lightning, and short circuit protection.

Electrical Current Stemming From Algae

Stanford scientists have harnessed a tiny electrical current from algae cells. They found it at the very source of energy production – photosynthesis - and it may be the first step toward generating high-efficiency bioelectricity that doesn't give off carbon dioxide as a byproduct.

Should human genes be patentable?

This week's question concerns the issue of gene patents. While some in the scientific community believe that human genes should not be exploited for commercial gain, others argue that a patent is a reward for years of expensive research that moves science forward.

What do you think? Should human genes be patentable?

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.
