IBC SOLAR, a leader in photovoltaic (PV) systems, will be attending the PV EXPO 2015, Japan’s largest international exhibition for the PV industry. From February 25 to 27, the German solar expert presents its services at a joint booth (E27-5) with the Japanese company Yokohama Kankyo Design (YKD). Besides,
The Energy Department's SunShot Initiative launched the largest-of-its-kind, 60-day online hackathon to quickly build prototype solutions and products that address barriers to greater solar energy deployment and drive down the costs of solar energy. Approximately 700,000 coders, developers, and data scientists
This wind tunnel constructed by NREL engineers will test the small wind turbines designed by 10 university teams competing in DOE's Collegiate Wind Competition.
Ten small wind turbines will go blade-to-blade in wind tunnel tests at the inaugural DOE Collegiate Wind Competition (CWC) that runs concurrently with the AWEA 2014 WINDPOWER Conference, May 6-7, at the Mandalay Bay Conference Center in Las Vegas, Nevada. Designed by university teams, these wind turbines will
Inverter load rejection overvoltage (LRO) tests completed by the Energy Department's National Renewable Energy Laboratory as part of a cooperative research agreement with SolarCity have proven so successful that a testing partner, Hawaiian Electric Companies (HECO), has proposed to double its hosting capacity

Ultra-precision, high-side current sensing is crucial in applications where one must measure the current entering or leaving a battery. Today many digital multimeters feature four-lead Kelvin sensing to eliminate the series resistance of the multimeter leads and give an accurate voltage drop across a given resistor.
Similarly,

Switch-mode battery chargers are popular choices in applications due to their topology flexibility, multi-chemistry charging, high charging efficiencies which minimize heat to enable fast charge times and wide operating voltage ranges. Nevertheless, some downsides of switching chargers include relatively high

The easily discerned lines separating cyberspace and the “real world” are disappearing. With the advent of the Internet of Things (IoT), physical objects are increasingly integrated in information systems and individuals are interacting with vast distributed networks dozens of times a day. Clearly, the IoT

In today’s increasingly hyperconnected world, it is essential that all new designs minimize power consumption and are protected from being cloned, reverse engineered, or tampered with in order to protect embedded intellectual property, system data, and the system itself. FPGAs play a key role in meeting
Dave Freeman, Texas Instruments
The Internet of Things (IoT) has been the topic conferences, articles, and blogs. Much of this has focused on the standards for communication and security of the information and devices. Just as important is powering the myriad of devices that comprise the IoT. It is worthwhile to first describe what makes up
According to the New York City government, buildings within its five boroughs are the single largest source of greenhouse gas emissions. New York-based clean energy company Bonded Energy Solutions concluded that the biggest compliance challenge that building managers faced involved how much energy their properties
Brian Williams of 3D Designs
In this podcast Brian Williams of 3D Designs talks to Alix Paultre of Power Systems Design about the next generation of energy generation, and a novel power-generation technology 3D Designs has developed. 3D Design's subsonic bladeless turbine (SBT) technology takes a working fluid from a reservoir in a vapor
Recently the first class of Marine trainees at Camp Pendleton will graduate from the Energy Department’s solar job training pilot program, which is aimed at preparing service members for careers in the solar industry as solar photovoltaic system installers, sales representatives, system inspectors, and other
In accordance with Governor Andrew M. Cuomo’s NY-SUN initiatives that are expanding New York’s clean energy industry and the US Department Of Energy’s (DOE) Sunshot Initiative to reduce solar energy installation costs to 6 cents per kWh by 2020, the US Photovoltaic Manufacturing Consortium (PVMC) has successfully

People have been wearing clothes almost since we began walking erect, and one thing we’ve learned over the millennia in our evolution in both ourselves and in our habiliments is that people have funky, dirty bodies. We have been strapping technology about ourselves and stuffing tools and devices into our clothes
Desert Sunlight Solar Farm
Secretary of the Interior Sally Jewell and Director of the Bureau of Land Management Neil Kornze joined California state and industry leaders to “flip the switch” on the Desert Sunlight Solar Farm, the nation’s largest solar project on public lands that is now delivering clean, renewable energy to American
QUANT F four-seater e-sports saloon with nanoFlowcell drive technology
nanoFlowcell, maker of the QUANT F, will have its world premiere at the 2015 Geneva International Motor Show on 3 March 2015. The four-seater e-sports saloon with nanoFlowcell drive technology is a further development of the QUANT E from 2014, the first automobile with flow cell drive to be approved by the German
In this podcast Ali Hajji of SEWT (Sun Energy and Water Technologies) talks to Alix Paultre of Power Systems Design about the technical and infrastructure challenges involved in deploying alternate energy technology in the developing world, in this case, Morocco. IBC
The Energy Department announced $13 million in funding to help communities across the country reduce market and policy barriers to solar deployment and recognize communities for taking the initiative to go solar. This investment will make it faster, cheaper, and easier for Americans to install affordable solar
