In 1839, French physicist Alexandre Edmond Becquerel discovered the “photovoltaic” effect, or the natural phenomenon which allows the conversion of solar into electrical energy. Over the next 150 years, this inexorably led to solar-powered satellites, solar cars, and solar-panel technology for domestic use. Among their many strengths, financial savings (after the initial investment), environmental conservation, and minimal upkeep, solar panels always suffered weaknesses inherent in a technology that relies on a giant ball of ionized gas 150 million kilometers away.
With soaring energy costs, all sectors are feeling the crunch, including the thermoelectrics industry. But Nextreme Thermal Solutions has a plan to stem the tide. One potential solution is to convert a system’s thermal energy byproduct into a functional resource. Using a grant from the North Carolina Green Business Fund, Nextreme plans to optimize their thin-film growth process with the goal of doubling the power output of a single device from 250mW to 500mW.
Researchers at TU Delft (Netherlands) and the FOM Foundation for Fundamental Research on Matter have found irrefutable proof that the so-called avalanche effect by electrons occurs in specific, very small semiconducting crystals.
It may have been a cold and damp morning in Manhattan, but that didn’t damp the passions of the participants in the Challenge X national collegiate engineering competition. This year’s challenge, sponsored by the US Department of Energy and General Motors, focuses on technology integration and full-vehicle development of advanced alternate-technology drivetrain and subsystems. By participating in the Challenge X program, the students gain real-world engineering skills and hands-on learning to better prepare them for a future career in engineering.
With the cost of energy approaching the insane, new and improved methods of creating better and more easily deployable solar power cells are very welcome. This advance in manufacture by Konarka Technologies promises to deliver cheaper power cells in large quantities. I hope they can commercialize the technology to the point we can use solar as a tricke-charge backup in every powered application exposed to the sun.
Improving the environment is always a good idea, but wireless companies are finding ways to go green while bringing more “green” to their bottom lines.
Wind power is breaking new records in Spain, accounting for just over 40 percent of all electricity consumed during a brief period last weekend. As heavy winds lashed Spain on Saturday evening wind parks generated 9,862 megawatts of power which translated to 40.8 percent of total consumption.
The goal is to inspire a new generation of viable, super fuel-efficient vehicles that offer more consumer choices.
GE Global Research announced the successful demonstration of “roll-to-roll” manufactured OLEDs. The company claims that this process is a key step toward lower costs of the technology.
Jim MacDonald, Zilker Labs, Inc. comments "The need for higher energy efficiency in embedded systems continues to rise on the priority list of systems developers and end users alike"
The concept of sustainable design started, not as a way of conserving the environment, but to prolong battery life in portable consumer goods such as cell phones, laptops and PDAs.
Researchers at MIT and Texas Instruments (TI) unveiled a new chip design for portable electronics that can be up to ten times more energy-efficient than present technology.
Energy News: IBM is leading a charge of freely available energy efficiency patents, as part of the World Business Council for Sustainable Development's new Eco-Patent Commons, officials said today. So far the commons has 31 patents, 27 being from Big Blue (not the football team). Nokia, Pitney-Bowes, and Sony also joined.
Productive Product: Sometimes technology ideas are so good and so obvious that we don't even dare to suggest them, for fear of being rebuffed with a sarcastic, "Yeah, right!" An example is the idea that all of life's gadgets could connect to a single universal power supply -- no more jumble
Productive Product: The Wall Street Journal (may require site registration) has a story about Aurora, Ohio's TCP Inc., the world's largest manufacturer of spiral compact-fluorescent light bulbs. TCP was the idea of a Chinese immigrant who is now benefitting from the Western energy-efficiency push -- they had sales of $300 million this year
