For a while, 2007 looked to be the year when organic photovoltaic (PV) technology would finally come into its own. Reports from leading research labs claimed record-setting breakthroughs in performance. Meanwhile, the U.S. Department of Energy (DOE) began welcoming investigators working on organic PV to compete for its mainstream solar-research grants, and venture capitalists invested tens of millions of dollars in organic PV development firms like Konarka Technologies, in Lowell, Mass., and Plextronics, in Pittsburgh.

Electric utility infrastructure habitually falls prey to overgrown Right-of-Way, high winds, and harsh weather. Impactful events causing outages are increasing in frequency, and need to be endured without major disruptions in electric service. This webinar will discuss the application of covered aerial conductor to "harden" the electric utility grid so that unpredictable events don't result in unsustainable outages.
