Retrofittable Device Converts The Water Heater Into A Smart, Networked And Energy-Efficient Appliance
Devin Coldewey for TechCrunch: An experimental solar cell created by MIT researchers could massively increase the amount of power generated by a given area of panels, while simultaneously reducing the amount of waste heat. Even better, it sounds super cool when scientists talk about it: “with our own unoptimized geometry, we in fact could break the Shockley-Queisser limit.” The Shockley-Queisser limit, which is definitely not made up, is the theoretical maximum efficiency of a solar cell, and it’s somewhere around 32 percent for the most common silicon-based ones. You can get around this by various tricks like stacking cells, but the better option, according to David Bierman, a doctoral student on the team (and who is quoted above), will be thermophotovoltaics — whereby sunlight is turned into heat and then re-emitted as light better suited for the cell to absorb.

Kinetic energy is power that is gained from motion, and this motion can involve vehicles, individuals, and any other object.
When customers can make choices in the energy market with their own dollars, the end result is that they are not only more aware of the market, but also able to direct future investment in energy infrastructure.
Axion Power International, Inc. (OTCQB: AXPW), created the PowerCube™, a 0.5 megawatt battery energy storage system using Axion's PbC® Battery, and began utilizing it as the first fast acting battery system to take part in the PJM network frequency regulation program.
Polysilicon prices plummeted mildly as strong dollar against RMB. The polysilicon price in China has stabilized in RMB term this week amid unwound frenzy. However, as affected by the strengthened dollar, polysilicon price in China translates to a drop in the USD term. Furthermore, the rinsing production in the top manufacturers spurred concern global supplies are once again topping demand. On the other hand, the price uptrend in the overseas market has been halted by the cooling sentiment in China. As the result, the drop in spot price of polysilicon this week is mainly resulted from the appreciation of the greenback, but the halted rallies in China and overseas implies the weakening sentiment after the production retrieval introduced by REC Silicon.
Renewable energy jobs continue to rise even as employment in the broader energy sector falls
Radian Generation (RadianGEN), an independent asset management and O&M firm providing comprehensive software and services to solar project owners, has closed a new round of investment with Solar Plus International (Solar Plus).
The North American Board of Certified Energy Practitioners (NABCEP) announced today that it has launched a national search for a new Executive Director.
Dr. Dan M. Ionel - Professor of Electrical Engineering and L. Stanley Pigman Chair in Power at the University of Kentucky - used his seminar at the recent CWIEME Berlin exhibition to highlight record-breaking developments in the design and materials for brushless PM machines.
Growing demand for highly-efficient yet lightweight transformers has opened up a new application for Wickeder Westfalenstahl's proven cold-rolled cladding. When used in the coil winding, the company's copper-clad aluminium can dramatically reduce the weight of a transformer without compromising on performance.
CWIEME seminar highlights how latest evaluation software ensures specifiers get the electric motor they need
Fabrice Marion, expert electrical engineer in CEDRAT's application team with responsibility for motor and generator solutions, used his seminar at the recent CWIEME Berlin exhibition to highlight how the FluxMotor software makes the task of evaluating electric rotating machine performance easy - for experts and non-experts alike.
On May 23rd, 2016, representatives from Ballard attended a ceremony to unveil the first zero-emission fuel cell bus to provide service for the Orange County Transportation Authority (OCTA).
