News and Recent Developments
- January 2013: Parabolic community solar cookers used for midday meals in rural schools - WORT is a nonprofit organization that has been operating in five Indian states since the early nineties. They have untaken a unique solar cooking project targeting Zilla Parishad primary schools in the Sangamner and Akole taluka of the Ahmadnagar district. The objective was to find ways to help prepare their midday meal. Currently, twenty-three solar cookers are in service. After a careful study of all options, it was decided to deploy the PRINCE - 40 parabolic solar cooker, designed by Ajay Chandak, for the pilot installation in fifty-three villages across three states – Maharashtra, Andhra Pradesh, and Madhya Pradesh. Most of the schools where these cookers are installed are using them as main source of energy for the mid-day meals.

- 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. The March edition of CNN’s Eco Solutions program highlights the Shirdi Saibaba temple solar steam cooking system.

- 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.

Contact: Fair Fabricators
- 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.

Upon winning the award, the Gadhias acknowledged Dr. Dieter Seifert and Wolfgang Scheffler, whose solar concentrator cooking technologies are promoted by Gadhia Solar.
- August 2006: Solar Alternatives and Associated Programmes (SAAP) is a nonprofit, charitable society committed to environmental protection and empowerment of the downtrodden through solar energy applications, particularly solar thermal technologies. Run by the Jesuits, and led by Fr. M.M. Mathew, SAAP conducts research, development, fabrication and installation of a variety of solar devices, including household solar cookers, community solar cookers, solar steam cooking systems, and solar food dryers. They have even developed a solar chapatti cooker. Many of SAAP's devices rely on solar concentrator technologies developed by Dr. Dieter Seifert and Wolfgang Scheffler, and the Solar Bruecke organization. SAAP empowers socially and economically depressed groups through employment opportunities as fabricators, as well as vocational training programs affiliated with the National Institute of Open Schools.

- 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
The History of Solar Cooking in India
India, Asia's second largest country, next to China, has also the second largest number of solar cookers. The situation in India is more complex than that of China. More is also known about Indian programs. The Third World Conference on Solar Cooking was held in India, permitting the history and progress of solar the technology's uses to become better known around the world.
An official government report informs the reader that the Ministry of Non-Conventional Energy Sources (MNES), Government of India, was established in 1982, first as a Department and later as a Ministry. The Ministry's mandate extends well beyond solar cooking, including fuel efficient wood and charcoal stoves, power from other renewable sources, energy from industrial wastes, research and development in a number of related fields (photovoltaics, biogas, and pollution prevention, for example). MNES began seriously to promote solar cooking in the early 80s, with an initial focus almost entirely on the box cooker.
The population of India is roughly 70% rural. MNES states that "cooking accounts for a major share of the total energy consumption in rural homes (Singhal, correspondence, 2003, p. 1). Sources of that energy are largely fuelwood, animal dung, or crop residues, all of which emit smoke, pollute the atmosphere, and are deterimental to health and safety of family members, particularly women. Fuelwood is become scarcer each year. FAO data show that 21.6% of the Indian land mass is forested, and conservation efforts are in place to reverse previous loss. The effort is affected by the large and dense population and a slowing but still substantial birth rate (continuing to increase at 1.7% per annum, or 17% in a decade). Solar cooking has been viewed as one way to alleviate a number of India's problems and as such was supported by government efforts.
The Press Bureau of the Government of India reported in 2007 that there are 525,000 solar cookers installed in India. The Press Bureau also reported in 2003 that, "The solar cooker programme has been expanded by introducing new designs for community use. Three solar steam cooking systems based on automatic tracking concentrating collective technology for cooking food for 600-3,000 people per day, and one system based on ‘Solar Bowl’ technology, have been installed. World's largest solar steam cooking system has been installed at Tirumala Tirupati. The system is designed to cook two meals for 15,000 persons in one day. Another system for 2,000 people was erected at Brahmakumaris Ashram in Gurgaon in July, 2002. Three community cookers for indoor cooking have been installed at a training hostel and an NGO’s establishment in Leh. In all, six such systems have been installed under the MNES demonstration scheme. A total of 500 dish solar cookers and 60 community solar cookers have been installed so far."
Climate, Culture, and Special Considerations
Solar Cookers International has rated India as the #1 country in the world in terms of solar cooking potential (See: The 25 countries with the most solar cooking potential). The estimated number of people in India suffering from fuel scarcity but with ample sunshine in 2020 is 157,400,000. In December 2007 the Indian Government instituted a program of rebates on various renewable energy devicesincluding solar cookers. Solar cooking has been recommended even in the Rig Veda which says: "All edibles ripened or cooked in the sun’s rays change into super medicine, the amrita."
The Economic Times of India reports:
- While 300 million people live below poverty line, making do with energy inefficient dung cakes, twigs and branches and occasional bits of coal, the urban middle class and the rural rich are splurging on cheap petrol, cheaper diesel, even cheaper kerosene, and absurdly cheap LPG.
- The subsidy is massive - hidden by a disingenuous device called oil bonds. Here are some rock solid facts. IOC, HPCL and BPCL are currently losing $137 million a day (i.e., Rs 582 crore per day at Rs 42.50 = $1). They lose Rs 16.34 for each litre of petrol, and Rs 23.49 for each litre of diesel sold in Delhi.
- The subsidy on kerosene at Rs 28.72 per litre is over three times the current retail price; and the subsidy on a cylinder of cooking gas at Rs 306 per cylinder exceeds the retail price. The total under-recovery for the oil marketing companies for 2006-07 was over $19 billion. With oil prices touching $135, under-recoveries can be $50 billion this year, unless retail prices are substantially increased.
In a report presented during the Asian Clean Energy Forum in June 2008, Soma Dutta, Asia regional network coordinator for the Amsterdam-based ENERGIA International Network on Gender and Sustainable Energy, says that only 45 percent of India’s 70 percent rural population have access to electricity, and over 80 percent still rely on firewood as their main cooking fuel. The long hours and big effort spent just gathering firewood give these women little time for education or employment, she adds.
Another take on the social acceptance of solar cooking in India:
Technologies have been failing in the villages for many reasons, but most commonly for lack of market knowledge on the part of the innovator. One example is the solar cooker, which was first developed about 20 years ago. This technology never caught on despite the purported cost savings because it was not created in a way that suited the lifestyles of the individuals using it. The solar stove was most powerful at the times of the strongest sunlight, which was mid-day and early afternoon. The population it was made for were largely village farmers who consumed their big meals by early to mid-morning and then again late at night, after the sun had gone down. In addition to this the stoves were not made in a way that was conducive to Indian-style cooking. The stove had four separate chambers which could boil or slow cook food. Indian cooking is mostly with oil (with the exception of rice) and requires frequent temperature manipulation and flipping and turning which was not possible with the solar stove.
There does however, appear to be references of solar cooking written in ancient Vedic texts:
Sun cooked food improves cellular health and longevity of life. It strengthens health and mind removes three major physical disorders to do with digestion, blood and respiratory system, balances inner body temperatures, life, glows aura and keeps various obstacles away. Sun cooked food has great medicinal value. It enhances intellect, genius. : ' Rig Veda'. - Reference from the princeindia.org website. See: PRINCE
