KOA Speer Electronics has introduced two new current sensing resistors, the zero ohm SLZ and the 1W/2012 SLW07. The high current SLZ1 jumper chip offers a rated current of 44A in a 2512 size. The SLW07 has an enhanced high power rating of 1Watt in a smaller package size of 2010. KOA Speer’s SLZ1 and SLW07 both feature a wide

As an outcome from the continuous hybrid renewable energy research, an innovative outdoor lighting system powered by a shroud-augmented wind turbine and a solar panel was installed in the KL campus of University of Malaya (UM). This hybrid green energy system is a compact design that harmoniously integrates a vertical-axis-wind-turbine (VAWT) with the novel omni-direction-guide-vane (ODGV), solar panel and LED

Linear Technology Corporation has added the LT8620, a 2A, 65V input capable synchronous step-down switching regulator. Synchronous rectification delivers efficiency as high as 95% while Burst Mode® operation keeps quiescent current under 2.5µA in no-load standby conditions. Its 3.4V to 65V input voltage range makes it ideal for automotive (single and dual battery) and industrial applications. Its internal high efficiency

San Diego, California – Impatience drives the materials science research of Shyue Ping Ong. The professor of nanoengineering says the world cannot afford to wait for a slow trial and error approach to discover new materials that could be used to build more energy-efficient technologies. The crisis of global climate change demands a faster and better answer. Ong was recently

While its light weight helps raise fuel economy in vehicles, carbon fiber has its critics. An often-long supply chain has led some to question the material’s environmental benefit. Recently, BMW defended the carbon footprint of carbon fiber in a recent WardsAuto article. The German carmaker is betting heavily on carbon fiber. It recently announced that it will triple production at

You know Top Gear, right? The UK car show with a trio of presenters who hate fuel-efficient cars, think electric cars are useless and like to scream around airfields in gas-guzzling supercars? James May has always been a little different. He often drives to the studio in a 1.2-liter Fiat Panda minicar, for instance, and last year he circumnavigated the

In an example of just how wrong stereotypes can be, the recent move by the Ohio State Senate to freeze the state’s renewable standard, along with its energy efficiency program, at 2014 levels for the next two years, is being strongly opposed by a number of (very possibly Republican) faith leaders in the region. Not really a surprise to anyone

Can you really call any activity that happens in the world of business “bullying”? I’m not too convinced that’s ever the right term — after all, business is business, as the phrase goes. And apparently Tesla Motors is all about business — at least according to Ecotricity’s founder Dale Vince. The Ecotricity head recently made the comment that the very

Yesterday, an almond grove in California’s Central Valley hosted the opening of the world’s largest iron-chromium redox flow battery. Originally pioneered by NASA, these flow batteries are emerging as a promising way to store many hours of energy that can be discharged into the power grid when needed. Traditionally, electric generation follows the demands of the daily load cycle. But

It turns out General Motors is a leader when it comes to patent filings, be they for regular or clean technology. The results of two leading studies from the Patent Board and Clean Energy Patent Growth Index show that General Motors (GM) is a leader in overall patent filings and those focused on clean energy technology. GM said it finished
