Debra Fiakas is the Managing Director of , an alternative research resource on small capitalization companies in selected industries. The U.S. Navy is laying claim to the first electric grid connected wave power generator in the country.  A test site has been set up near military facilities at Kaneohe Bay in the Hawaiian Islands, where wave activity is known to be exceptional.  Yes, Hawaii is part of the United States.  The project consists of two wave-power generation systems or ‘power buoys’ anchored about a half-mile off shore.  The two buoys are connected by undersea cable to the Marine Corps base at Kaneohe and ultimately to Oahu’s electric power grid.The first of the two buoys is produced by Northwest Energy Innovations .  Itswave energy device was first deployed at the Hawaii test site in June 2015.  The buoy sits atop the ocean with about 12 feet rising above the waves and another 50 feet extending below the surface.  The system weighs 45 tons and uses both up and down as well as side to side motions to generate electricity.  Northwest got help installing the Azura in Hawaii from a contractor, Sea Engineering, which also helped with the assembly and launch.  The Azura was developed in collaboration with Callaghan Innovation , a government agency of New Zealand and Energy Hydraulics Ltd ., also located in New Zealand.It seems that ‘takes a village’ to put a wave power buoy into the ocean.  The corrosive conditions of salt water and the dangers presented by the unpredictable waves and currents present significant challenges for engineers.  Device design, materials, anchoring and grid connections each present unique hurdles.The second buoy was developed by Fred. Olsen Ltd. based in Great Britain.  Its Lifesaver wave power system is a 50-foot wide and 3-feet thick doughnut-shaped device, which is anchored to the ocean floor by cables.  It is the action of the cables as the ocean moves that turns the generator.  The Lifesaver was put in place at the Hawaii site in April 2016, with help from Healy Tibbitts Builders and Sea Engineering, Inc. The smaller of the two buoys, the Lifesaver is expected to generate about 4 kilowatts.The Kaneohe projects is a first for the U.S., but not a first for the world.  The first grid-connected wave power station in the world was turned on in early 2015 of the coast of Western Australia by the device developer Carnegie Wave Energy Ltd CWE :  AUS or CWGYF:  OTC/QB).  There are limited ocean power grid connections in the United Kingdom and Norway as well.  The U.S. has remained behind developers in these areas where the engineering community has been quicker to embrace innovation and where public policy has been supportive of alternative energy development.  Over the past decade the U.S. military has invested about $300 million in hydrokinetic research and development, well behind investments in the United Kingdom, Australia and northern Europe.  The Hawaii project has been made possible by financial support from the U.S. Navy, which has interests in reducing energy costs at Hawaii military installations.The Navy will collect performance data from the Hawaii project in the coming months, which will be used to make adjustments to the power buoys installation as well as to the grid connections.  Northwest Energy Innovations also plans changes in its Azura power buoy to increase electric output from 20 kilowatts to 500 kilowatts.For now the companies involved in the Navy’s project in Hawaii are all privately held and are beyond the reach of most individual investors.  Wave power is still in the nascent stages and few ocean power projects underway anywhere have reached the point of generating power on a consistent basis.  Some investors might remember solar energy in the 1980s, when solar cells had been proven capable of generating electricity but had not consistently generated profits for any company.  With practical knowledge of system design, construction and operation accumulated, the early companies were eventually able to achieve scale and then began generating consistent income streams.The realization of a full and complete grid connection in Hawaii makes ocean power more certain for U.S. coastal markets.  In a study commissioned by the U.S. Department of Energy, RE Vision Consulting estimated that the theoretical ocean wave energy resource potential in the U.S. could satisfy more than 50% of the country’s annual demand.  This is a resource that cannot be ignored no matter how challenging the engineering work.

Maximum entropy inference can be used to find equations for the critical currents (Jc) in a type II superconductor as a function of temperature, applied magnetic field, and angle of the applied field, θ or φ. This approach provides an understanding of how the macroscopic critical currents arise from averaging over different sources of vortex pinning. The dependence of critical currents on temperature and magnetic field can be derived with logarithmic constraints and accord with expressions which have been widely used with empirical justification since the first development of technical superconductors. In this paper we provide a physical interpretation of the constraints leading to the distributions for Jc(T) and Jc(B), and discuss the implications for experimental data analysis. We expand the maximum entropy analysis of angular Jc data to encompass samples which have correlated defects at arbitrary angles to the crystal axes giving both symmetric and asymmetric peaks and samples which show vortex channeling behavior. The distributions for angular data are derived using combinations of first, second or fourth order constraints on cot θ or cot φ. We discuss why these distributions apply whether or not correlated defects are aligned with the crystal axes and thereby provide a unified description of critical currents in superconductors. For J//B we discuss what the maximum entropy equations imply about the vortex geometry. © 2013 by the authors.

Spotty diffraction rings arise when the size distribution of crystallites illuminated by the incident beam includes crystallites that are large compared with the size of the beam. In this article, several statistical measures are used in conjunction to quantify spottiness and relate it to a crystallite size distribution: the number of peaks, the normalized root mean square intensity variation and the fractal dimension. These are demonstrated by way of example using synchrotron X-ray diffraction patterns collected during in situ corrosion of mild steel in carbon dioxide-saturated aqueous brine. © 2014 International Union of Crystallography.

A cable winding machine for winding transposed cable from multiple serpentine subconductors such as in particular Roebel cable from such 2G HTS tape, without damaging the tape through edge-wise bending, comprises a conductor supply stage carrying subconductor supply spools to move the supply spools about a machine axis and maintain the supply spools in a common orientation as the subconductors unwind and move through the machine in a machine direction, and a cable forming stage after the conductor supply stage in the machine direction, arranged to bring together the subconductors and at which the subconductors interleave to form the transposed cable.
