An improved, cost-effective catalyst for water-splitting devices
Solar energy appears to be the only form of renewable that can be exploited at level that matches the world’s growing needs. However, it is equally necessary to find efficient ways to store solar energy in order to ensure a consistent energy supply when sunlight is scarce. One of the most efficient ways to achieve […]
In-Depth: Cleantech at the National Labs
To see that the clean energy economy is creating jobs in communities across the United States, look no further than the Energy Department’s recent Revolution Now report – which shows rapidly falling prices and rising deployment of clean and renewable technologies. Thanks to federal and private sector investments, clean energy technologies like wind power, solar, […]
RAMBO a small but powerful magnet
Rice University system allows high-magnetic-field experiments on a tabletop HOUSTON – (Jan. 6, 2014) – Rice University scientists have pioneered a tabletop magnetic pulse generator that does the work of a room-sized machine – and more. The device dubbed “RAMBO” – short for Rice Advanced Magnet with Broadband Optics – will allow researchers who visit […]
Tesla station to bring electric cars to Wyoming
LUSK, Wyo. (AP) — In the least populated county in the least populated state, old Ford and Chevy pickup trucks roam — and rule — the roads. Finding a Tesla, the sleek and pricey all-electric car, around these ranching towns is about as likely as spotting the mythical jackalope. And yet, one day last month, […]

Ex-BP Engineer: Juror Misconduct Tainted Verdict
Defense attorneys for a former BP engineer convicted of trying to obstruct a federal investigation of the company’s 2010 Gulf oil spill claimed Thursday that jurors engaged in misconduct that warrants a new trial. Kurt Mix’s attorneys asked U.S. District Judge Stanwood Duval Jr. to throw out the jury’s Dec. 18 verdict convicting Mix of […]
Finding Ways to Minimize Power Grid Disruptions from Wind Power
Researchers from North Carolina State University and Johns Hopkins University have found that an increase in the use of wind power generation can make the power grid more fragile and susceptible to disruptions. But the researchers didn’t just identify the problem – they have also devised a technique for coordinating wind power generation and energy […]
One-Watt DC/DC converter targets industrial applications
Murata announced the MEF1 Series of 1-W regulated DC/DC converters. Suitable for use in industrial, automation and instrumentation applications, these tightly regulated single output converters, rated to better than 1 percent of nominal output voltage, are packaged in a fully encapsulated single-in-line through-hole format occupying less than 1.17 cm squared footprint. The MEF1 converters are […]
Opto-less, wide input range DC/DC converter extends operating life to 30 years
Absopulse’s DRH-150 wide input range, long-life DC/DC converter for rugged industrial environments is designed for an operating life of up to 30 years. By eliminating optocouplers in the feedback loop and significantly reducing component count, the MTBF of the unit is greatly improved over conventional designs, according to the company. Large design headroom, full electronic […]
