| Abstract | The highest demonstrated efficiencies in solar power systems are achieved in Concentrated Solar Power (CSP) systems using a two-axis tracking parabolic dish collector (PDC) with a Stirling engine mounted at the focal point (CSP-Stirling System). Such systems have demonstrated 25% efficiency in converting solar energy to electricity. Unfortunately, such systems are also very costly. An alternative system makes use of an array of small (20cm diameter) parabolic collectors with inexpensive mirrors each directing the sunlight to a single optical fiber. The optical fibers from each mirror in the array transport the light to a central receiving unit that converts the light energy to heat for use with the Stirling engine. In addition to the solar heating element, there is also a propane or natural gas heating element that can augment the solar energy when clouds come by or during the evening hours. This system combines the advantages of a CSP-Stirling system with a much less costly solar collection system achieving about 20% solar to useful power (electric plus hot water) conversion in practice. The addition of the propane/natural gas system allows for 24-hour operation and the addition of batteries for electrical storage can serve as an interface to the home or to the grid. Such a system is appropriate for both remote off-grid operation and for on-grid integrated systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
