Photovoltaic Power Without Batteries for Continuous Cathodic Protection

The objective of this project was to successfully demonstrate that renewable energy can efficiently and economically replace dedicated non-renewable power sources. The COASTSYSTA designed, installed, and started up on 20 Jan. 1990, a state-of-the-art photovoltaic powered impressed current cathodic protection system (PVCPSYS) for steel and iron submerged structures. This system does not require any auxiliary/battery backup power. The PVCPSYS installed on 775 ft. of steel sheet piling of a Navy bulkhead is continuing to provide complete, continuous corrosion protection. This installation is well documented by COASTSYSTA and was verified on-site by the U.S. Army Corps of Engineers. The PVCPSYS uses only renewable energy and is environmentally clean. A patent is pending on the new technology. Other possible PVCPSYS applications are mothballed ships, docks, dams, locks, bridges, marinas, and pipelines. The Department of Defense Photovoltaic Review Committee and Sandia National Laboratories consider this successful and cost effective system a major advance in the application of photovoltaics

Critical elements essential for exemplary educational leadership : a reflective essay

My core beliefs are very. strong when it comes to education. All students need effective staff members who are supportive of their endeavors. A supportive staff member is someone who is apart of the school community, they work well with others through effective communication, they support each other, and they all work toward the common shared vision of the school. My core beliefs match my goals to become an effective principal and the way I live my life. The cultivation of a supportive community within a school happens over a period of time. The principal is the captain that leads the staff in the direction that fosters the educational mission and benefits the students. The critical ways an effective principal pulls a staff together is through strong community relations, strong management skills, supportive mentor programs, and inclusive visionary skills. I am inspired to go out there to put forth my best effort to become a successful administrator

A Reading Classroom Isn\u27t Grimsville

Elementary perhaps, but during a 1967-69 compensatory program designed to increase communication skills for post-secondary but not fully qualified college students on a southern black university campus, we figured that to learn was to attend-in both a mental and a physical sense
