Dear Readers & Friends,

This just came down the wire: The Indian energy group Reliance has awarded the French multinational Areva a contract to build the two  125 MW (so total of 250 MW) Concentrated Solar Power (CSP) plants in Rajasthan (in northwestern India), using the French company’s Compact Linear Fresnel Reflector (CLFR) technology.  This 250 MW CSP project in India is scheduled to come online in May of 2013 and will be the largest of its kind in Asia.  The first phase of the project has already begun and it will represent a reduction of around 557,000 tons of CO2 emissions annually compared with a coal-fired plant, according to Areva. India aims to build an additional 20 GW of solar capacity by 2022.  The chief executive of Reliance Power JP Chalasani hinted that this may/will be the first of many solar projects to be built by the two companies, “Today’s announcement is just the beginning. We look forward to working with Areva in helping to meet India’s clean energy goals through this project.”  CLFR (Compact Linear Fresnel Reflector) technology uses reflected sunlight to heat liquid-filled tubes which generate high-pressure steam that produces electricity via turbines. The CLFR solar steam generators are simple, durable, and scalable, and relatively quick to install;they are also able to generate 1.5- to 3-times more power per acre of land than other competing solar technologies, making CLFR solar steam generators the most land-efficient renewable energy technology in operation now. Here is a short video clip on how Areva Solar’s Compact Linear Fresnel Reflector (CLFR) solar steam generators can augment fossil-fired power plants without added emissions, below:

This Reliance contract with Areva solidifies Areva Solar’s position as a leading global supplier of CSP (Concentrated Solar Plant) for large-scale standalone power plants, power augmentation of fossil-fired power plants and solar hybrid applications. Areva has about 500MW of CSP capacity in operation under construction in advance development at the moment. The deal with Reliance is part of a major push by the French engineering company Areva to set up its activities in the solar sector around the world: in Australia, it has been contracted to build a 44 MW solar thermal in addition to the coal-fired Kogan Creek power station;in USA,it has secured a partnership with Tucson Electric Power to develop a solar augmentation project in Arizona.  Apparently solar is not the only area of Areva’s interest; just days before, Areva had won a key deal to supply turbines to a 500 MW offshore wind project in northern France;Areva will also produce 100 of its 5 MW turbines at a new factory in the French port of Le Havre through a working partnership with Spanish utility Iberdrola and UK’s wind developer RES.  Yes, one can see that solar and renewable energy world are full of efforts through cooperation and that Areva will be leaving much of its renewable energy footprints throughout our planet earth.

The Challenge of Designing a Solar Cookstove That Works at Night

Dear Friends and Readers,

Do you remember our January posts (Jan. 5, 6, 7, 9, 2012) regarding solar cookers ?  Take a look/read of them to refresh your memory.  Then, I will discuss a new challenge with you.  As some of you may have tried and  found out, solar cookers only work for a few hours in the middle of a sunny day, but not at night or in the mornings when people actually want to cook.  If we can use solar cookers any time of the day and night, it could replace open fires, solve dire deforestation, and indoor air pollution problems in developing countries.  So, last year, the Climate Healers, an international development technology organization, issued a design challenge after their traditional solar cookers failed to catch on in mountain villages in Rajasthan, India.  The Climate Healers is designing a new cooker that stores the solar energy by day to release it at night.  Students at the University of Iowa, working with Climate Healers, surveyed the women (who would use such a cooker) and found that they were enthusiastic about a new design that will enable them to use solar cooking during nights.

The starting point is a modified Blazing Tube solar cooker that serves as a baseline,

but it needs improvement. So, the Climate Healers has turned to the E4C (Engineering for Change) for help.  The baseline design places a three-gallon glass cylinder in the crook of a compound parabolic reflector-basically a tube on the bottom of a half pipe.  The tube filled with one gallon of oil and an air bubble, warms throughout the day and releases heat at night or the next morning through a heat pipe that the chef controls.  Climate Healers replaced the oil and air with three gallons of table salt.  The salt heated to 626F (330C) at the center of the tube, enough to yield 1KW hour of energy, enough to cook flat bread and lentils for about an hour.

 

The head of Climate Healers, Sailesh Rao, feels more needs to be done before reaching the final design because of the requirement for transporting large, fragile tubes to remote regions and the need to store adequate energy without leaks all need to be met.  So these three aspect need to be considered: 1. Energy capture 2. Energy storage 3. Energy delivery.

Just think that these designs have the potential to contribute to better health and healthier forests in India and many parts of the world.  Since early 2011, many teams of people have accepted the challenge of making a solar cookstove that works at night.  By Dec. 25, 2011, ten designs meeting this challenge had surfaced.  I would like to invite you to visit these ten designs of solar cookstove that works at night . These ten designs are: iHawk Cooker, Heat delivery system, PETE induction cookstove, CARES stove, Scheffler cooker, Solar box cooker, Parabolic cooker with steam, Box cooker with steam, Molten-salt solar cooker, Solar cooker with oil.

My hat off to Climate Healers and Engineering for Change (E4C) !  Again, we see the importance of the cooperative effort in solving our world’s problems, meeting our world’s challenges.
