Solar Water Pasteurizer: The Answer to Preventable Illnesses and Deaths in Developing Countries?



Discover home solar today with solar water pasteurizer and lessen the staggering death due to contaminated water in third world countries. Many non profit organizations believe that lack of safe drinking water and sanitation facilities are the root causes of hunger, disease and poverty throughout these countries.

Pasteurization is the process of killing microorganisms in food or liquids by heat or radiation. The word “pasteurization” was named after the French doctor Louis Pasteur, who demonstrated that diseases are caused by microorganisms that can be killed by heating to 55ºC/131ºF for several minutes.

Pasteurization is a function of time and temperature.  If heat is applied for a long period of time, disinfection will occur at a lower temperature. At higher temperatures, disinfection occurs in shorter period of time.

The dreadful results of contaminated water according to the experts:
  1. An estimated 4.6 million children and adults die from diarrhea each year
  2. The leading cause of death for children under the age of five in developing nations is infection from waterborne diseases
  3. The primary cause of diarrhea is contaminated drinking water
  4. 1.2 billion people do not have access to drinking water free from disease-causing microbes
  5. 50% of hospitalizations in developing countries result from waterborne disease
Advantages of solar water pasteurizer:
  1. It is 99.999% effective in destroying water-borne pathogens like bacteria, viruses, protozoa and worms
  2. Uses only the heat of the sun; does not use electricity, chemicals or fossil fuels.
3.Superior alternative to chlorine treatment, which is rated “poor” at destroying worms & protozoa, may be bad for one’s health, and gives water a bad taste.

Boiling water to kill water borne pathogens is common in some third world countries. They use firewood, charcoal and other fuels. Families spend up to 25-30% of income on firewood or water purchases. Gathering firewood for cooking and boiling water takes family members 6-8 hours. This makes solar pasteurization a better alternative.

The World Bank states, "Despite decades of effort...and $30 billion of water investment in developing countries each year…an estimated 10,000 people…die every day from water and excreta-related diseases. Thousands more suffer debilitating illnesses. The tragedy is that these deaths and illnesses are entirely preventable.

The statement is an eye opener. Perhaps it is high time for local governments to take a serious look at the growing problem and institute meaningful reforms. Non profit organizations can likewise reevaluate  their programs and continue to work hand in hand with the government and non government organizations (NGO) in these countries.

Will Teaching Solar Alleviate Poverty in Developing Countries?



Discover home solar today is a message that should reach the developing countries. Efforts in this direction initiated by the local government and non profit organizations worldwide are mainly directed to the adult population for faster results. The efforts however, fell short of expectations so that these countries continue to be mired in poverty. No doubt there are difficult hindrances which can not be overcome at present.

This article will attempt to recommend teaching solar to children in grade school with ages ranging from 10 to 15 years to augment the programs now being implemented in these developing countries. Teaching solar is based on a premise that community problems like safe water, deforestation and food preservation are difficult to solve and need long range solutions.

The long range solutions should start with very young people.The young students should be taught solar in general with special emphasis on its thermal applications on the identified problems. The things that the students will learn are relevant, affordable, implementable and badly needed by the community.

These thermal applications should include solar cooker, solar pasteurizers and distillers and solar food dryer.. Adoption of these solar thermal devices will impact on health problems with safe drinking water, tree deforestation and preservation of excess harvest for the lean months ahead. 
  
The above topics should be included in the grade school curriculum like gardening and home economics. Because the technology is simple, a 15 year old boy can easily understand and build  solar cooker, distiller or dehydrator from locally available materials. Other aspects of solar energy can also be incorporated in the teaching.

Why should teaching solar emphasize thermal applications?


Consider these facts and observations:

1.       The World Bank states, "Despite decades of effort...and $30 billion of water investment in developing countries each year…an estimated 10,000 people…die every day from water and excreta-related diseases. Thousands more suffer debilitating illnesses. The tragedy is that these deaths and illnesses are entirely preventable.”
2.       1.2 billion people do not have access to drinking water free from disease-causing microbes.
  1. 80% of all illnesses in the developing world result directly from waterborne pathogens.
  2.  Approximately one billion people suffer from diseases contracted by consuming contaminated water.
  3. 50% of hospitalizations in developing countries result from waterborne disease.
6.       Research has found that 36% of the world's fuel wood needs (or 350 million tones of wood per year, according to UNICEF) could be replaced by solar box cookers, saving 500 kg of wood per family per year, equivalent to millions of trees.
7.       The search for fuel consumes the time, energy and health of women and their children. As local wood supplies grow scarce, women risk spinal column damage and uterine prolapsed from carrying heavier loads over longer distances.
8.       Half the inhabitants of Earth cook over wood fire. Nearly half the world's wood supply is used as fuel. But there's not enough of it to go round -- more than 2 billion people now face shortages of fuel wood.
9.       Nutritionally, dried food is ranked by the USDA as better than canning, just under freezing.
10.   Solar food preservation is a simple low cost way to preserve food that might otherwise spoil. It is one of the oldest ways of preserving the harvest, and lets you save food without using electricity.

The need of developing countries is immediate relief from the burden of cooking, deforestation, access to safe drinking water and simple ways of preserving excess harvest. Efforts must continue and be maintained in these directions.

But we should not discount long range solutions which would provide effective and long lasting relief. The long range solution include teaching solar must be studied carefully to fit a particular developing country.

Will teaching solar alleviate poverty and why thermal applications? Yes, solar will help ease poverty because of practicality of its application and simplicity of implementation. Thermal uses should be emphasized because of its affordability and availability to everyone.

When a beginner thinks of acquiring a home solar system, the inevitable question comes up:  Can I build it myself or do I have to get the services of a professional? Will I have the time to work or is fund available for outside services.
There are a number of factors to consider and eventually it is only the beginner who can decide whether to build or hire a professional. This article will attempt to explain why many solar users favor getting a professional to build their home solar power. 

9 Advantages of hiring a professional installer:

1.       Professional installers have undergone extensive training. They are experienced people who have dealt with many problems in solar energy installation. You can always rely on their years of solar installation experience for a functioning and trouble free home solar system.

2.       Their work will be guaranteed.  They will use higher quality, name brand solar panels with good warranties because customers will hold them responsible for anything that goes wrong. Their expertise will also be available for any needed repairs or upgrades.

3.       Professional installers will do additional work which does not include direct installation.  A good solar installer will include site evaluation, system design, parts, labor, and interconnection in his quote. He can also help you through the mountain of paperwork and permits necessary to install your system.  He knows the ins and outs of the building codes and ordinances in your area,

4.      These professionals know the incentives and rebates in your area and will ensure that your solar system meets the proper requirements.  A number of these incentives are available only for professional solar installation. They will also help you file for solar rebates because they are intimately familiar with the programs.

Do-It-Yourself (DIY) Home Solar System: Find out the Main Drawbacks before Building One


Much has been written about Home Solar System and the homeowner doing the building himself (DIY).  At a glance of the manual, it looks like a piece of cake with the homeowner gathering the materials and finishing the System in 1 or 2 weekends.

The Solar DIY manual boasts it’s so simple the homeowner does not need any basic knowledge of electricity. It raves of a System that costs less money than a professionally installed one. This is true but what the manual fails to mention is the attendant difficulties for a homeowner doing the work for the first time.

Here some of the drawbacks and unfortunate experiences of some homeowners who took the DIY route:

·         Here’s the story of one DIYer:  With high hopes, I searched around for a good guide to help me. I bought one guide after another, hoping each guide can help me build my DIY project.  My bookshelf and hard drive were replete with instructional guides. But none of them helped. All I found were nothing but rehashed material from textbooks and many of them simply copied each other’s work. Some were so difficult and too time consuming to understand. Others lack crucial information that left me high and dry. Yet others lacked customer support. Lesson of the story: request from DIY Manual promoter for names of people who have  installed their DIY Home Solar System and hear their story.

·                    *          If you have done DIY projects in the past, you might be aware of the hidden costs in time and frustration. Remember that every time you make a mistake you pay for it.

·                    *     Remember also that the panels and other devices you make do not carry any warranty. If anything goes wrong you are on your own. Panels built by reputable companies carry warranty.

*         Even solar panels with good warranties (20+ years) may have their warranties invalidated by unprofessional installation. Find out before you buy.

*      Any project involving electricity requires you to know what you’re doing. Any mistake may prove costly and dangerous.

·                       *   Since you are doing it alone, you also will have to contend with licenses from the state, secure permit and arrange inspection by the utility grid. 

·                        *   You also will have to find out what federal, state and private incentives are available to you and the requirements to avail of these incentives.

·                         *        Professional and experienced installer can provide you with sound advice on all aspects of solar installation saving you dollars in the process.

On the other hand, installing your own home solar panels is a challenge if you're a handy man who is willing to do the research and has the skills to work on the project. In the process you will acquire a clear understanding of how solar energy works in your household and be prepared for problems that may come.You can surely enjoy considerable savings with DIY solar.

Solar Food Dehydration: Sunlight’s Practical Way of Preserving the Harvest with Zero Fuel Cost




 Solar food dehydration is the process of removing water from fruits and vegetables by circulating hot air through it, thus preventing the growth of enzymes and bacteria. These organisms cause the food to deteriorate. This process is a simple low cost way to preserve food that might otherwise spoil. 

It is one of the oldest ways of preserving the harvest, and lets you save food without using electricity. Solar food drying can be used in many areas.  How fast the food dries is affected by many factors such as the amount of sunlight and relative humidity. 

General guidelines
  • Wash fresh fruits and ripe vegetables thoroughly.
·          Cut  into thin pieces, not more than about 1/4 to 3/8 inch thick)
  • Spread thinly on trays initially giving an allowance of a third to a half of the screen area clear for the passage of air. It can be made more compact after the first moisture is gone.
  • Typical drying time ranges from 1 to 3 days, depending on sun, air movement, humidity, and type of food.
  •  Remove 80 to 90% of moisture from the food.
  • Once the drying process has started it should not be interrupted, do not allow freezing.
  • Direct sunlight is not recommended.
  • To test if food is sufficiently dried, remove a piece and let it cool. Vegetables should be brittle. Fruits because of their sugar content may never get beyond a firm bend or leather quality.
  • Allow food to cool completely before storing.
  • Store food in air tight jars or plastic containers, and do not expose dried food to air, light or moisture.
How to acquire one

Solar Cooker International (SCI) is one of the leading proponents in the use of solar cookers especially in third world countries. Cookit, the simplest cooker is being promoted as a diy device very popular in depressed areas. Many ready to use food dehydrators are also available in the internet.

 Some dried foods can be eaten as-is after dehydrating but many are soaked in water again to improve their texture and flavor before cooking. Most foods are allowed to stand for 15 minutes (equal parts packed food and water) before being added to standard recipe.

 Stored dried food is prepared every growing season. Food prepared this way should be used within the next months as the nutritional value slowly drops over time. By preserving food the solar way you become a part of the generation who has trusted the sun for efficient consumption of food.

Beginners Take Note: Sun Energy Increases Home Value


Increase in home value is desired by everyone who makes changes and invests in the home. Home value can come in many forms.  It maybe comfort added as in constructing an adjoining room or a patio. It maybe something of aesthetic value as in a beautiful landscaped garden.  Or it can be an increase in monetary value especially when a homeowner thinks of savings and selling the property in the future. Increase in property value of homes powered by the sun is one of the benefits that entice homeowners to go solar.

What do the experts say?

1.       According to the U.S. DOE’s office of Energy Efficiency & Renewable Energy, a home with solar will sell twice as fast as a home without solar – even in depressed markets1.
2.       The real estate appraisers said that for every $1 of electricity you offset through solar, the value of your home increases by $20. In other words, saving $1,000 per year increases your home’s value by $20,000. 
 
3.   All other things being equal, a home with a lower electric bill will sell faster. 
4.       Electricity demand is increasing in most major markets and this increase combined with projected higher fuel costs for utilities will probably lead to higher electric bills for most consumers. A solar system installed will help insulate consumers from these potential price shocks
5.       A solar home’s value goes up faster. According to Shea Homes, the value of California homes with solar went up 55% while non-solar homes went up 45% during the same time period3.
6.       All 257 homes in one Clarum Homes development sold within a year of being put on the market, 2 years faster than planned. Plus, homes originally priced at $379,000-$499,000 were selling for as much as $600,000.
7.       The faster increase in a solar home’s value and the increase in its resale price are a result of the value the solar electricity will bring to the homeowner in the future. In other words, minus any maintenance and repair costs, solar adds value to a home because it means the homeowner will save more and more over time on electricity.
8.       While payback periods will vary, in most installations where a system is justifiable, the system will indeed pay for itself in a reasonable amount of time.
9.       It’s a great thing knowing that you're doing your part to lessen dependence on foreign oil and improving the environment.

It has been established that of all home improvements, installation of solar electricity gives the best return of investment. It recovers 100% of the cost. The benefits experienced by established solar users confirmed that through solar power, they make themselves solutions to the ever increasing energy demand and global environmental pollution problem.

Cooking with Sunlight: Simple Solution to Complex Tree Deforestation Problem?



 Will cooking with sunlight in lieu of firewood make a dent in the loss of forest trees? It is known that tree deforestation had been a problem for decades and continues unabated up to this day. Will solar cooking make a difference in the efforts of various sectors to halt or slow down forest destruction?

Tree deforestation is markedly visible in third world countries where forests are lost continuously at the rate of millions of hectares every year. The impact of this loss is reflected in lives of people who continue to wallow in poverty, poor health and difficulty in pursuing a sustainable livelihood. For this reason alone, promotion and adoption of solar cooking must be pursued.

This article will attempt to explain how solar cooking can help preserve the forest and immensely improved life in the third world countries.

Relevant observations and facts.

1.      Forests in the developing countries are shrinking by millions of hectares per year partly because nearly half the world's wood supply is used as fuel.
2.      Indoor smoke pollution (from fire wood) now ranks 8th in health burden worldwide (lost years of healthy life), and ranks fourth in the "least-developed" countries (which make up about 40% of the world population) according to the World Health Organization's World Health Report 2002
3.      UNICEF estimates that 60% of rural families and 23% of urban families in developing countries are without safe water. Boiling guarantees safe drinking water and this cannot be done because of scarce firewood fuel
4.        In some villages in the third world countries, people depend on their livelihood from selling fire wood collected from the forest. Gradually they find shortage of fire wood and forest resources are fast being depleted.
5.     Studies reveal that the poorest urban households spend 20-40% of their income meeting daily cooking requirements, and the poorer the home, the higher the percentage of income spent. Currently with a total of more than 1.4 million sets of solar cookers in use, China is the number one country in the world promoting solar cookers.

 How solar cooker can help ease tree deforestation

1.      Solar cookers can replace fire wood for cooking food. Research has found that 36% of the world's fuel wood needs (350 million tones of wood per year, according to UNICEF) could be replaced by solar box cookers, saving 500 kg of wood per family per year, equivalent to millions of trees. Solar cookers saved an estimated 50 -60% of firewood the poorest urban household use.
2.      Promotion of solar cooker should be widespread with emphasis on poor countries. Efforts in this direction are already very visible but more is still to be done.
3.      Research on solar cooking must be intensified. Unfortunately, growing access to cheap coal and petroleum has overshadowed this solar research in the last century. Fossil fuel subsidies in the poorest countries have also slowed the development of solar cooking technology. There was little incentive for serious research on solar technology for cooking until recent decades when firewood became a rapidly diminishing resource and an increasingly expensive commodity.

During the last decades solar cookers have been increasingly used as a solution to the firewood problem. And because of this, fewer trees are chopped down, thus reducing deforestation and the advance of desertification, while at the same time guarding against global warming.

The rapid deforestation in many areas and the expanding of carbon-based atmospheric cloud are good reasons for a massive global effort to spread this technology. Hundreds of millions of families who still cook using wood, dung and charcoal should be encouraged to use solar cookers.

 Did you know that the world’s largest solar kitchen is located in India and serves approximately 20,000 people a day?
