Cooking in the kitchen at Shirdi

• April 2010: Gadhia Solar Energy Systems Pvt. Ltd. recently completed installation of an enormous solar steam cooking system, capable of cooking 40,000-50,000 meals per day. It is located at Shirdi Saibaba temple in Shirdi, Maharashtra, India. With nearly 30,000 visitors each day, the temple’s dining halls are some of the largest in India. The solar steam cooking system is comprised of 73 rooftop-mounted reflective dishes of 16 square meters each. The dishes concentrate sunlight on receivers that contain water, generating steam that is piped down to the kitchen for cooking purposes. To maintain constant focus with the sun, the dishes automatically rotate throughout the day after being manually aligned once each morning. The solar steam cooking system is retrofitted to existing liquid petroleum gas-powered steam boilers that are still used in the evening and during prolonged periods of inclement weather. Though the solar steam cooking system cost nearly $300,000, government subsidies reduced the temple’s portion to about $170,000. Liquid petroleum gas use has been cut by roughly 100,000 kilograms each year, for an annual savings of approximately $45,000. The temple should recoup its investment in three to four years. According to company founder Deepak Gadhia, the solar steam cooking technology was originally developed in Germany. However, the equipment does not contain imported components and is manufactured with local machinery and labor, creating much-needed jobs. Gadhia has adapted the system for use in India, and has installed 50 such systems of varying sizes over the past two decades.

• March 2008: A March 2007 white paper — by Dr. Veerabhadran Ramanathan, distinguished professor of climate and atmospheric sciences at the Scripps Institution of Oceanography, University of California, San Diego (USA), and Dr. Kalpana Balakrishnan, head of the Environmental Health Engineering department at Sri Ramachandra University, Chennai, India — outlines a project to reduce air pollution and global warming with community-wide use of solar cookers and improved biofuel cooking devices. The authors provide many referenced details about the negative health and environmental impacts of biomass burning and biofuel cooking, which they say are “the major sources of elemental carbon (EC) in India and other developing nations.” Carbon dioxide and EC, or soot, are the “two largest agents of global warming.” In India, where a reported 90 percent of cooking is done over wood- and dung-fueled fires, several studies have documented that “indoor air pollution leads to 400,000-550,000 premature deaths … from lower respiratory infections and chronic obstructive pulmonary disease. … The burden falls disproportionately on women and children, who inhale soot and other particles from smoke released by the burning of biofuels.” This soot combines with outdoor air pollution to form atmospheric brown clouds (ABCs) that “envelope most of India and the Indian Ocean … [leading] to a large reduction of sunlight at the ground and … atmospheric solar heating.” Since EC and other particles in ABCs have relatively short lifetimes compared to carbon dioxide in the atmosphere, the authors believe global EC reductions can “give us a decade or two to come up with viable and sustainable alternatives for fossil fuel combustion.” In the proposed “Project Surya,” solar cookers will be distributed in 65 villages in the Periyar PURA region in the Thanjavur and Pudukkottai districts of Tamil Nadu, benefiting approximately 6,500 households that currently use about 5 kilograms of firewood per day. Other fuel-efficient cooking devices will be available for use at night or on inclement days. The region has a strong base of local nongovernmental organizations and social networks, including women’s self-help groups, that will be useful for project implementation. Input and feedback from the communities will be gathered and used in a number of ways. Surveys of eating habits and estimated cooking fuel requirements will be conducted. Meetings with local leaders will be used to demonstrate a range of solar cooking technologies and to solicit feedback on their suitability and probability of acceptance in the communities at large. Educational outreach and incentives will be used to maximize use of clean cooking technologies. Installation, operation and maintenance training programs will be offered for those interested. Data collection will begin six months before the project launch, and will continue for at least a year after. Using special instrument towers, researchers will measure concentrations of particulates and soot content, as well as surface solar radiation. If feasible, indoor air pollution will be monitored using special equipment installed in select homes. (Alternatively, a mobile laboratory may be used.) Children will be involved as well, collecting data on cooking fuel use and cooking times, among other things. This data will help quantify the reduction in biofuel use and soot emissions. Though the authors state “it is difficult and costly to [accurately] quantify the disease burden due to indoor air pollution,” they “propose to build the evidence for expected health improvements … through documentation of exposure reduction and subsequently through reduction in incidence and severity of diseases.” The stated goals of the project, in order of importance, are: 1. To eliminate the detrimental health effects of indoor smoke; 2. To reduce the negative effects of EC in ABCs on the summer monsoon rainfall, Himalyan glacier retreat and agriculture; 3. To mitigate the global warming effects of CO2 and elemental carbon. Contact: Vanessa A. Balta Cook, Center for Clouds, Chemistry and Climate at SIO-UCSD.

The new 2.3 meter parabolic Community cooker ready for operation

• November 2007: Professor Ajay Chandak, of Promoters and Researchers in Non-Conventional Energy (Prince India), reports completion of an ambitious project to manufacture, transport, install and commission over 300 large parabolic solar cookers at tribal schools in the Indian state of Maharashtra. The project was coordinated by Chandak, with manufacturing by PRINCE trainees M/s Essential Equipments and three contractual manufacturers. Twenty-five trained teams carried out installation and testing of the cookers. The entire process took just 45 days, and resulted in 100 schools being equipped. The Community solar cookers, as Chandak refers to them, are 2.3 meters in diameter and powerful enough for a 22-liter pressure cooker. Each cooker cost around Rs. 26,000 ($650) and comes with a large pressure cooker and other accessories.

• October 2007: Finally the awareness to harness Solar energy and use it to cut costs and save money has arrived in Mumbai. Cut Cost Technologies have introduced the Fuel-Free Cooker in Mumbai, INDIA. Surprisingly its use, in Mumbai, is going to be pioneered by an NGO which is already at the fore-front of adopting renewable energy Sources. The Fuel Free Cooker is an addition to their other renewable energy exploitation. They already have in place solar water heaters and a bio gas plant. Surely more will follow the example of this NGO and save money by cutting costs....because the money saved will be used for the larger good of the society.

• April 2007: Sankha Subhra Datta has designed a solar box cooker that is suspended at two points within a support frame, allowing for rotation of the entire cooker around a horizontal axis from 5 to 70 degrees with respect to the ground. The cooker can therefore maintain a nearly 90-degree angle to the light as the sun's position in the sky changes. The cooker is rotated around a horizontal axis by repositioning a bar that is attached to the lower front corners of the box between any of 14 slots spread across the base of the frame. Datta says this system has advantages over solar box cookers with tilt-adjusting rear legs — a greater range of rotation can be achieved, and the cook can rotate the unit smoothly without having to lift its entire weight and risk food spillage. Another design feature that helps to prevent food spills is the weighted, rotating cooking tray that keeps the pot horizontal at all times. Regardless of cooker rotation, the pot is always at the center of the cooker because the tray rotates on the horizontal axis of the pot. "This tray holding arrangement is designed for proper utilization of top and bottom reflectors at every inclination … which is not possible in simply suspended tray arrangements [because] shifting of pot location from the central position of the inner box due to the rotation of pot around pivots," Datta says. The cooker frame sits on casters for easy rotation around the vertical axis. The outer box is constructed of galvanized iron and the inner box is aluminum, with glass wool insulation in between. The glazing is double-paned glass with a two-centimeter air gap.

• November 2006: An article by M.A. Siraj, appearing in the November/December 2005 issue of Refocus magazine, highlights a solar cooking system installed by Gadhia Solar Energy Systems for the Indian Army. Here is an excerpt: "The Indian Army has commissioned a giant solar cooking system at Leh in the state of Jammu and Kashmir. Located in the Ladakh region at 4,000 meters, it is said to be the world’s highest altitude solar cooking system with the capacity to prepare food for 500 army personnel. Mr. Deepak Gadhia of Gadhia Solar Energy Systems … [said] this was one of the most challenging projects undertaken by his company as the team had to work in extremely adverse climate conditions such as snow, cold winds and sub-zero temperatures. … Prior to solar cooking being introduced, the army kitchen at this base was using nearly 50 kilograms of liquefied petroleum gas and 70 liters of diesel each day to cook food. Described as an icy desert, the region has no vegetation and hence no firewood. Diesel and gas cylinders are transported by air for the Army and the tribal population. The solar cooking system has halved the consumption of these fuels. Gadhia says the heat is generated by five pairs of 9.5 square meter parabolic reflectors which produce steam that is piped down to the kitchen for cooking purpose." Due to the cold climate, the system requires thick pipe insulation, and must be regularly drained of water when not in use.

Solar steam cooking system mounted atop Tirumala Tirupati Devasthanam

• March 2006: Representatives from hotels and educational institutions gathered recently in Tirupati, Andhra Pradesh, to learn about solar concentrating systems for steam generation that can cook thousands of meals daily. Representatives from other industries that could benefit from solar steam generation also attended. The meeting was organized by the Non-Conventional Energy Development Corporation of Andhra Pradesh (NEDCAP) and sponsored by the Ministry of Non-Conventional Energy Sources (MNES). Mr. Deepak Gadhia, Managing Director of Gadhia Solar, detailed how solar concentrating systems work and mentioned several industrial uses in addition to cooking: incineration, waste water evaporation, solar desalination, solar air conditioning and solar space heating, to name a few. Two testimonials were provided. First, Mr. Malliah, Vice President of Sanghi Employee Welfare Association, told of how he attended a lecture by Mr. Gadhia a few years earlier and was convinced that his organization needed to install such a system, given that they are always looking at ways to reduce costs, improve efficiencies and protect the environment. Their system, which cost about $12,500 after a 50% government subsidy, is working well. Costs were recouped within two years. Next, Mr. Kachwaha told of a system that was installed in a silk processing plant. Not only did this system reduce energy costs, but it also reduced noise and air pollution within the plant, resulting in a better work environment and greater productivity. The system has since been repurposed from solar steam generation to solar water heating, with a daily capacity of 1600 liters. After the gathering, participants toured the world’s largest solar steam cooking system at Tirumala Tirupati Devasthanam. The system is comprised of 106 rooftop-mounted parabolic concentrators that generate steam for cooking up to 30,000 meals daily. The gathering was covered in a number of newspapers and appeared on television news stations. Contact: Jagadeeswara Reddy

• January 2006: Professor Ajay Chandak of Promoters & Researchers In Non-Conventional Energy (PRINCE) led a workshop titled “Manufacturing Parabolic Solar Cookers and an introduction to renewable energy technologies.” Twenty people from eight states participated in the workshop, mostly renewable energy professionals. Mr. Chandak hopes that several of them will consider manufacturing parabolic solar cookers in their own states. Large community-size cookers, two meters or more in diameter, proved quite popular. These cookers can cook meals for 30-50 people. Smaller, family-side cookers were also shown, as were related technologies like solar food dryers. Contact: Ajay Chandak, Prince India
