Linking Solar Energy With Agriculture In India

a week ago
  India is aggressively pushing for solar power with a 100 GW target for 2021-22. The installed capacity crossed 20 GW in 2017, with 18.4 GW in the form of ground-mounted projects and 1.6 GW on rooftops. This provides us with the opportunity to innovate in terms of systems design and link solar power to India’s labour-intensive agriculture sector. The trend in India is the promotion of large solar parks with capacities more than 250 MW, at each location, in bigger states. The official solar park target has been increased to 40 GW. Recent tenders for these parks have driven the tariff down to less than Rs 2.50/unit, making solar cheaper than coal. However, ro...

“CENTRES IN VILLAGES TO HELP SPREAD SCIENCE LITERACY”

2 weeks ago
Science and technology communication can help spread scientific way of thinking among people and make science accessible to them. Establishing science centres in villages can help achieve this, said Y Joykumar Singh, Deputy Chief Minister of Manipur, while addressing the 11th Science Communicators’ Meet at the Indian Science Congress.  He said science communicators play a vital role in communicating the basic understanding of science. “Virtual museums and interactive programmes are tools in the arsenal of science communication. Television, radio, webcasting, use of satellites, blogging are gifts of techno...

The moon will have its first 4G cell phone network in 2019, the network builder Vadafone has said. The German branch of the multinational telecommunication company has teamed up with Nokia to do the mission, London-headquartered Vadafone said in a statement. The network is to support a private lunar rover mission by PTScientists, a private space company based in Berlin, which plans to launch a lander and two small rovers to the moon on a SpaceX Falcon 9 rocket, Xinhua news agency reported. The PTScientists said their team is committed to bringing down the cost of space exploration and democratising access to the mo...

A team of archeologists at Indian Institute of Technology Gandhinagar, conducted a survey of an unexplored area of around 12,276 square meter at Dholavira using Ground Penetrating Radar (GPR) technique which helps scanning of the ground and reveals objects buried underground. The GPR data suggests existence of a set of small and shallow reservoirs possibly connected with the existing Eastern Reservoir. The depth of these reservoirs has been estimated to be around 2.5 meter below the present ground level. In addition, some structures have been found containing rubble with some features. These findings suggest the possible ...

VIDEO GAMES FOR STROKE RECOVERY

8 weeks ago
Video games, popular among kids in the 1990s, have made a comeback with the advent of virtual reality (VR) which gives users a sense of touch when augmented with add-on instruments. A group of Indian engineers and neuroscientists has put these advances to use in a field which is not entertainment– recovery of stroke patients. Stroke is one of the leading health problems and causes of disability in India. It affects muscle weakness and movement disabilities related to the upper limb. The rehabilitation of such patients usually involves physiotherapy involving repetitive exercises, but this has to be carried out by tr...

NEW TECHNOLOGY FOR UPSCALING MEMORY

8 weeks ago
Silicon-based memory devices such as hard drives and flash drives are in high demand for gadgets that require storage. Conventional semiconductor material-based memory devices have limited scale-up ability to increase their storage capacity.  Hence, there is a quest in developing new memory technologies with superior characteristics. In this direction, a group of Indian researchers has developed a new type of resistive random access memory (RRAM) device that can be controlled with magnetic fields. Researchers at Indian Institute of Technology Hyderabad have demonstrated the control of resistive switching characterist...

 Dinesh C Sharma If anybody can become a dancer as depicted in 2013 Bollywood dance drama, Anybody Can Dance (ABCD), directed by choreographer Remo D’Souza, why can’t anybody become an astronomer and make new discoveries?  Yes, says Dr Ananda Hota, radio astronomer at the Centre for Excellence in Basic Sciences (University of Mumbai-Department of Atomic Energy) in Mumbai, and he has shown how. He is the founder of a unique citizen science project, RAD@home Astronomy Collaboratory, which trains lay citizens to analyse radio astronomy data from professional telescopes so that they can make discoveries.  Members of this project have made ...

As the incidents of  accidental explosions and fires caused by domestic gas cylinders keeps increasing,  two Bengaluru youngsters , both teenagers, have designed a sensor which can detect gas leaks and alert people in advance. Purushottam N (14), a Class 9 student of Government High School, Uttarahalli, and his sister Shravani N (16), a first-year Pre-university Commerce student of Dayanand Sagar College, have designed the sensor to exhibit it at the college’s talent search competition. Purushottam says , “To solve the problem of accidental fires and explosions of gas cylinders, we used Arduino ...

SpaceX successfully launched the world’s most powerful rocket, a towering behemoth known as the Falcon Heavy that tore through the sky with the thundering force of 18 Boeing 747 jetliners. The maiden flight marked the first time a privately financed venture ever attempted to launch a rocket so powerful that it was capable of hoisting a payload out of Earth’s orbit. As a promotional stunt, SpaceX founder Elon Musk loaded the Falcon Heavy with his own cherry-red Tesla Roadster carrying a spacesuit-clad mannequin named “Starman” in the driver’s seat. Lifting off at 3.45 p.m., on Fe...

Weeds are a persistent problem for farmers. A recent assessment by the Directorate of Weed Research shows that India loses crops worth US $11 billion dollar every year to these farm intruders. This study, published in journal Crop Protection, was carried out on 14 major crops and utilized data from 1581 on-farm research trials covering various districts of 18 states in the country. The study evaluated yield loss in three types of field plots  - plots where weeds are left uncontrolled; where weeds are managed by manual or mechanical weeding practice and plots where weed control was done by both manual weeding and herbicide a...

The use of ultraviolet lamps in water purifiers is common but the presence of mercury in these lamps could be potentially hazardous. Now a group of Indian scientists have developed a mercury-free ultraviolet lamp that can be used in water purifiers. Scientists have engineered an optimized dielectric discharge based mercury-free Vacuum UV/UV light source for water sterilization. The lamp can produce desired level of wavelengths for deactivation of bacteria within ten seconds without the use of mercury. The lamp has been developed by scientists from two CSIR labs -  Central Electronics Engineering Research Insti...
