The $50,000 first prize winner is WaterSHED (@watershedasia), an NGO that engages local enterprises and governments to develop sustainable, market-based approaches to effective water and sanitation provision in Cambodia, Laos and Vietnam. 

An estimated 1.8 million households in rural Cambodia do not have access to safe sanitation. WaterSHED's research demonstrates that Cambodians desire a shelter for sanitation facilities and will not purchase a latrine without an appropriate accompanying structure. Prize money will be used for WaterSHED's "Introduction of improved toilet shelter for increased sanitation coverage" project, developing shelters for sanitation facilities which are acceptable to local communities.

The $25,000 second prize winner is Gadgil Laboratory at the University of California, Berkeley, for its "Sustainable and scalable arsenic remediation of groundwater in South Asia" project.  Deaths and disease are linked to high levels of naturally occurring arsenic in untreated groundwater throughout South Asia. Through their invention, Electro-Chemical Arsenic Remediation, Gadgil Laboratory will bring safe water to local communities in West Bengal, where arsenic contamination of groundwater is rife. 

The technology uses ordinary steel plates and low DC voltage. Prize money will be used to establish a 15 month field trial for approximately 2,500 school children, with excess arsenic-free water sold to the village community.

This year also saw the award of the first-ever WASH Alliance prize of $15,000 for the third place project. The WASH Alliance is a consortium of six Dutch NGOs promoting hygienic use of sustainable water and sanitation. The WASH Alliance is providing all three winners with relevant training and professional development up to $ 2,500 each. They also get access to Elsevier's ScienceDirect database, with over 57,000 articles on Environmental Sciences, for one year.The recipient was Text to Change (@texttochange), an NGO that produces innovative mobile solutions for development, for its "WaterMonitor: Managing water supply and engaging communities at scale" project.

The UN Joint Monitoring Programme has estimated that water points in Africa fail between 30 percent to 60 percent of the time. Text to Change will use smartphone technology to map Uganda's water points and alert experts when repairs are needed in order to extend the life of the country's water points. The prize money will be used to map water points and educate 15,000 people on issues related to safe water, hygiene, and sanitation.

From 140 original applications, a shortlist of five candidates was chosen; the winning projects are replicable, scalable, sustainable and innovative; emphasizing solutions with practical applicability.

"We are proud to support this year's important winning projects, which harness advanced thinking in design, technology and community involvement, to address the need for reliable sanitation and water for thousands in the developing world," said Youngsuk "YS" Chi, Director Corporate Affairs at Reed Elsevier and Chairman of Elsevier, at the ceremony in Stockholm. "At Reed Elsevier, we produce scientific material which we are making available to the winners to progress their work.  We are delighted the Environmental Challenge adds three powerful new water and sanitation initiatives to four great projects we've supported over the last three years."

The Challenge's distinguished panel of judges includes Dr. Sarah Bell, Senior Lecturer in Environmental Engineering, University College London; Professor Mark van Loosdrecht, Department of Biochemical Engineering, Delft University of Technology; Dr. Prasad Modak, Executive President, of India's Environmental Management Centre; Professor Gang Pan, Research Center for Eco-environmental Sciences, Chinese Academy of Sciences; and Engineer Hanny Maas, Programme Manager of the Dutch WASH Alliance. The projects will be featured in the Elsevier Journal of Water Research.Reed Elsevier Environmental ChallengeReed Elsevier is Elsevier's parent company. The RE Environmental Challenge was launched in 2011 to contribute to the Water for Life Decade, established by the UN General Assembly between 2005 and 2015 in order to reduce by half the proportion of the population without sustainable access to safe drinking water and basic sanitation.Learn more on the RE Environmental Challenge website.

<p>Dear sir,</p>


<p>I am suresh kumar, an income tax officer in chandigarh.

I am working in a building which is centrally A/C .I got the idea of using the exhaust wind of Air conditioning plant to rotate the turbine for producing energy .If my idea of producing electricity from windmill which can be rotated by the exhaust of A/c plant comes true ,then there will be an Energy revolution in the areas where there is no wind mill due to lack of constant flow of wind. Till date the wind mill works in only coastal areas and not in places away from coastel regions .</p>

<p>The A/c plant works for at least 12 hours and that means the the wind mill can generate energy daily for twelve hours without need of natural wind . In off duty hours if there is natural wind ,the wind mill can produce energy, but for at least twelve hours the exhaust air can rotate the wings of windmill and the air can be utilised for energy production which is otherwise going waste.</p>

<p>This is an idea to produce energy by using the exhaust air from Air conditioner in A/C buildings which is otherwise going waste.I just want to let the world know about the utility of Air from Exhaust of Air conditioner which is going waste.By my calculations we can produce energy equal to 12-15% of the total energy consumption in a building having an A/C plant . The cost of Wind mill turbines can be recovered in three years and after that the energy is produced free of cost . In this way we can produce energy in the places far off from coastal areas where till date no wind mill energy is working due to lack of constant flow of wind .</p>


By implementing this technique of horizontal wind turbine we can produce 26% cost of the energy of the investment which is needed to start this project and the production is totally green , there is no carbon emmission,no smoke,no pollution and we are only using the wind that otherwise is going waste all over the world.</p>

<p>The wind turbine is not going to effect the efficiency of the A/C plant,rather it helps the A/c plant as can be seen from the lab experiments.</p>


1.Benefits of the exhaust air energy recovery system

The energy recovery system is designed in a way that the released waste energy from any exhaust air system is converted to useable energy. As the wind from the exhaust air is readily available and concentrated every time the exhaust air system is operating, the energy generated from the system is predictable and constant in value. With constant rotational speed of turbine, over speed control is not required as only small rotational speed fluctuation is experienced. This feature can increase the longevity of the turbine due to less fatigue experienced. Besides, wind blown by the exhaust‘s fan has a better quality compared to natural wind. Thus, the statistical analysis of wind characteristic over a period of time is not required before deployment of the turbine. In addition to that, selection of the wind turbine for the system would be simpler because the rated speed of the turbine is based on the exhausted wind and power output generated from the system is easily predictable.</p>


<p>Parameter Cooling tower without wind turbine /Cooling tower with windturbine /Cooling tower with wind turbine and diffuser 0 ..85 00mA 0.85 mA 0.85 mA

206.3222206.377 W 204.38 W 203.78 W

Average intake air velocity 1.97m/s 2.28m/s 2.14m/s

Intake air flow rate 1.05m/s 1,22m/s 1.14m/s

Motor current consumption 0.85mA/ 0.85mA 0.85 mA

Motor power consumption 206.37 w 204.38w 203.78w</p>

Turbine speed – 464rpm 501rpm 514rpm

<p>An exhaust air energy recovery system without resulting in negative impact is designed. The performance of the( Wind turbine-)WTs are efficiently boosted by integrating with an enclosure. Diffusers mounted at an optimum angle created venture effect and the exhausted air flow was improved. Besides, common safety mishaps such as blade failure problem are eliminated with the installation of the enclosure. It could act as a protective cover to protect the entire system. -Due to the simplicity of the design, this energy recovery system is retrofit-able to any existing exhaust air system with minimum visual impact.</p>

<p>From the laboratory test conducted, installed WT is able to generate electricity without pulling down the original performance of the cooling tower. Instead, the cooling tower’s performance was enhanced as air volume flow rate to the cooling tower is raised 8.6% higher. By integrating the WT with an enclosure to the design, the WT’s performance is improved where the rotational speed is raised from 463.72 rpm to 500.98 rpm. On site testing was conducted to further confirm the actual performance and reliability of this system. It was observed that the released air speed from the cooling tower increased by 0.4% more compared to the conventional cooling tower. In terms of the motor’s power consumption, there was no significant difference observed for both test cases (7.0~7.1 kW). The implementation of this energy recovery system is possible to conserve power consumption from the cooling tower by up to 13%. By turning what was a wasted energy to useable energy like electricity, this energy recovery system has a high market potential and fast payback period as there are numerous usages of exhaust air system globally. It can be used as supplementary power for building lightings or fed into the electricity grid for energy demand in urban buildings.</p>

<p>Hope the above will be sufficient for making my point clear.</p>

<p>If you so desired ,i can send my project report .It is for all and i want to implement it for the benefit of mankind.</p>

<p>Thanks and regards,</p>
