High Efficiency Solar Thermal Cooling System


Recently world’s highest efficiency solar thermal cooling system was inaugurated at the Solar Energy Centre in Gurgaon in Haryana. The new 100 kW Solar Air-Conditioning System works at 30 % higher efficiency than the current available systems and has several unique features. It is based on the new triple effect absorption cooling technology. The system has indigenously built medium temperature high efficiency parabolic troughs for collection of solar energy and effective solar thermal energy storage in the form of Phase Change Materials.

The present system will cater to air-conditioning needs of 13 rooms of Solar Energy Centre. To achieve this, 288 sq meter of Solar Collector area has been installed which generates nearly 60 kW of 210 o C Pressurized hot water. This heat is used in Vapour Absorption Machine to generate 7 o C Chilled water which in turn circulates through the Fan coil unit installed in the thirteen rooms. The major attraction of this system is that the hottest days have the greatest need for cooling and simultaneously, offer the maximum possible solar energy gain

कर्ण और कृष्ण का संवाद - रामधारी सिंह 'दिनकर'

Following is excerpt from poem Rashmirathi written by Ram dhari singh dinkar. Karna reply to Krishna when he told story of his birth and ask him to join pandava side. सुन-सुन कर कर्ण अधीर हुआ, क्षण एक तनिक गंभीर हुआ,  फिर कहा "बड़ी यह माया है, जो कुछ आपने बताया है  दिनमणि से सुनकर वही कथा मैं भोग चुका हूँ ग्लानि व्यथा  मैं ध्यान जन्म का धरता हूँ, उन्मन यह सोचा करता हूँ,  कैसी होगी वह माँ कराल, निज तन से जो शिशु को निकाल  धाराओं में धर आती है, अथवा जीवित दफनाती है?  सेवती मास दस तक जिसको, पालती उदर में रख जिसको,  जीवन का अंश खिलाती है, अन्तर का रुधिर पिलाती है  आती फिर उसको फ़ेंक कहीं, नागिन होगी वह नारि नहीं  हे कृष्ण आप चुप ही रहिये, इस पर न अधिक कुछ भी कहिये  सुनना न चाहते तनिक श्रवण, जिस माँ ने मेरा किया जनन  वह नहीं नारि कुल्पाली थी, सर्पिणी परम विकराली थी  पत्थर समान उसका हिय था, सुत से समाज बढ़ कर प्रिय था  गोदी में आग लगा कर के, मेरा कुल-वंश छिपा कर के  दुश्मन का उसने काम किया, माताओं को बदनाम किया  माँ का पय भी न पीया मैंने, उलटे अभिशाप लिया मैंने  वह तो यशस्विनी बनी रह

Scheme for creation of National Optical Fiber Network for Broadband connectivity of Panchayats

The Union Cabinet recently approved a scheme for creation of a National Optical Fiber Network (NOFN) for providing Broadband connectivity to Panchayats. The objective of the scheme is to extend the existing optical fiber network which is available up to district / block HQ’s level to the Gram Panchayat level initially by utilizing the Universal Service Obligation Fund (USOF). The cost of this initial phase of the NOFN scheme is likely to be about Rs.20,000 crore. A similar amount of investment is likely to be made by the private sector complementing the NOFN infrastructure while providing services to individual users. In economic terms, the benefits from the scheme are expected through additional employment, e-education, e-health, e-agriculture etc. and reduction in migration of rural population to urban areas. As per a study conducted by the World Bank, with every 10% increase in broadband penetration, there is an increase in GDP growth by 1.4%. NOFN will also facilitate implemen

किसको नमन करूँ मैं भारत? - Kisko Naman Karu Mein Bharat?

A poem dedicated to the nation written by Ramdhari Singh "dinkar"... तुझको या तेरे नदीश, गिरि, वन को नमन करूँ, मैं ? मेरे प्यारे देश ! देह या मन को नमन करूँ मैं ? किसको नमन करूँ मैं भारत ? किसको नमन करूँ मैं ? भू के मानचित्र पर अंकित त्रिभुज, यही क्या तू है ? नर के नभश्चरण की दृढ़ कल्पना नहीं क्या तू है ? भेदों का ज्ञाता, निगूढ़ताओं का चिर ज्ञानी है मेरे प्यारे देश ! नहीं तू पत्थर है, पानी है जड़ताओं में छिपे किसी चेतन को नमन करूँ मैं ? भारत नहीं स्थान का वाचक, गुण विशेष नर का है एक देश का नहीं, शील यह भूमंडल भर का है जहाँ कहीं एकता अखंडित, जहाँ प्रेम का स्वर है देश-देश में वहाँ खड़ा भारत जीवित भास्कर है निखिल विश्व को जन्मभूमि-वंदन को नमन करूँ मैं ! खंडित है यह मही शैल से, सरिता से सागर से पर, जब भी दो हाथ निकल मिलते आ द्वीपांतर से तब खाई को पाट शून्य में महामोद मचता है दो द्वीपों के बीच सेतु यह भारत ही रचता है मंगलमय यह महासेतु-बंधन को नमन करूँ मैं ! दो हृदय के तार जहाँ भी जो जन जोड़ रहे हैं मित्र-भाव की ओर विश्व की
