Nancy Pfund, the founder of DBL Investors, has supported some of the most successful modern clean energy companies, including Tesla, SolarCity, Powerlight and BrightSource. And unlike many other venture capital firms, DBL isn’t backing down from some of the riskier, capital-intensive investments. Other portfolio investments include CIGS manufacturer Siva Power, and storage companies Primus Power and PowerGenix. The firm is now in the process of raising a third fund worth $300 million. In this podcast, we’ll talk with Pfund about what she looks for in company strategies, why Tesla and SolarCity have been so successful, and how she’s trying to bust political myths about cleantech. Later in the show, we’ll debate a controversial new working study from Georgetown University economist Arik Levinson that concludes California’s energy efficiency policies did little to lower the state’s energy use. We discuss that study and counter-arguments from efficiency advocates. Finally, we’ll look at what’s behind SunEdison’s acquisition of Solar Grid Storage. This podcast is sponsored by Kaco New Energy, a leading manufacturer of solar PV inverters for every size and module type. The Energy Gang is produced by Greentechmedia.com. The show features weekly discussions between energy futurist Jigar Shah, energy policy expert Katherine Hamilton and Greentech Media Editor Stephen Lacey.

Canadian companies should learn from the past, and take full advantage of Canada's great fiber and the talented people working in the domestic industry to leverage their competitive advantage. Canada's unique fiber characteristics can compete with lower cost alternatives provided we are delivering good value. The impossible goal is to always be prepared to further improve the country's high quality products and enhance the value chain by finding innovative ways to make the customers more successful.

Profiles of tensile strength along bleached kraft fibrelines have a common shape - a relatively steep decrease between pilot-plant reference pulp and its corresponding mill-made brownstock, then a much shallower one in bleaching, and a steeper one again across the pulp drying machine. The absolute level of tensile strength at any mill location depends primarily on original wood fibre morphology and on the mill's equipment and fibreline operations. Alone, pulp drying causes a loss of 1 km or more of breaking length in softwood kraft pulps, and is located in final drying. In a Flakt dryer, sheet solids content and tensile strength are inversely and linearly related through all but the first few decks. The best ways to counteract this phenomenon are to begin with as slender fibres as possible (e.g. by wood species, and by maximizing juvenile wood and earlywood), and to produce the pulp in a digester system known to preserve tensile strength during pulp-making.

A noninvasive scheme for real-time and online detection of interturn winding faults in single-phase transformers has been proposed. A terminal measurement-based transformer modeling technique is central to the fault detection scheme. First, with the experimentally acquired primary line voltage and line current data of the healthy transformer, a healthy no-load model of the transformer is generated. Next, a healthy estimated indicator value, computed from this model under the given input voltage condition, is compared with the actual indicator value for detecting the presence of an interturn winding fault. Experiments have shown that the proposed scheme is not only capable of detecting incipient levels of interturn winding faults on primary and secondary windings under any load conditions, but also can estimate the fault severity level. In the end, a procedure to determine a suitable tripping threshold to de-energize the transformer under incipient fault has also been outlined. © 1986-2012 IEEE. Source
