A significant amount of work goes into the complex process of designing and planning a photovoltaic (PV) power plant, whether on the rooftop of a building or ground-mounted on the field. This then translates into an efficient, working PV power plant in situ. With the rapid uptake of PV, it Read more
Pasteurization is a process involving heating liquids rapidly to kill harmful organisms. Interestingly, the liquid does not have to be heated to boiling point for pasteurization to occur. Task You need to work in a small group to build a solar pasteurizer. It must be made from recycled materials and Read more
As the reserves of nonrenewable sources of energy are falling down in the nature we need to look for some other alternatives in place of these sources. Some of the renewable sources of energy are wind, solar, small hydro, etc., but these sources are distributed, hence if we could find Read more
For Lighting up Households in Slums and Rural Areas A low-cost and energy-efficient device has been developed to capture sunlight and light up households, particularly in urban slum or rural areas which lack electricity supply. Micro Solar Dome (MSD) has been developed by the Department of Science and Technology in collaboration Read more
Solar energy as an education subject normally involves physical science and engineering, but sometimes depending on the student category, also economics and social science. It is necessary to introduce solar energy concept from the very early stage of education. For primary level, the courses demonstrate the principle of solar energy Read more
Solar water disinfection has been explored and many types of small and big gadgets have been developed. It is the UV-A ray component that kills bacteria of different types. Although glass is considered to be impervious to the UV rays, but it was confirmed that ordinary soda-lime–silica type (window or Read more
In this article, we shall explain the fabrication of a small aircraft fly on solar power. The aircraft is radio controlled using the usual transmitter-receiver pair used in aeromodelling. The aircraft has a wing of span 2.5 m and chord of 30 cm with no tapering or sweep angle. The Read more
Solar cells based on perovskites reach high efficiencies as they convert more than 20 per cent of the incident light directly into usable power. On their search for underlying physical mechanisms, researchers of the Karlsruhe Institute of Technology (KIT) have now detected strips of nanostructures with alternating directions of polarization Read more
Humans need food and water for survival. Cooking is ubiquitous in human life as a daily ritual. It is considered to be an important influence in human evolution for survival and sustenance. Charles Darwin considered ‘the art of making fire’ as probably ‘the greatest discovery’, except language, ever made by Read more
The project was put up by the Group as a Demonstration Project for the clients intending to install biomass gasifiers for their electricity needs. Ownership towards ‘Green India’ is a one of the motivating factors for the investment. The Company further plans to install such demonstration projects in East Africa and Western Read more
