Kerala – Gods own Country ?

The 11th Kerala Environment Congress (KEC 2015) will be held at Kottayam, from 6th to 8th May, 2015.

The focal theme of this year’s Congress is “Climate Change and Sustainable Development

Climate change has now emerged as the biggest developmental challenge for the planet. The IPCC 5th Assessment Report, has clearly mentioned that the warming trends and increasing temperature extremes have been observed across most of the world over the past century. The report has provided compelling evidence that climate change is advancing rapidly as a global risk with impacts far beyond just the environment. Even though the climate change is affecting various development sectors, there is also scope for reducing emissions and deliver jobs and economic opportunity through wise use of resources. The KEC 2015 will be a thought provoking process in this direction, with the participation of people from all walks of life like scientists, researchers, policy makers, development managers, NGOs, media etc. The Congress will also identify the research and policy needs for developing viable programs to address climate change issues in the ongoing development process in India with particular reference to the State of Kerala.

Among the various topics on which Scientist would be presenting their papers the following above topics would be covered.

It’s estimated that in Kerala, forest is cleared at a rate of 60 to 100 sq km per year.  Several hundred species of trees, herbs and climbers are either endangered or vulnerable to extinction. 

Deforestation inevitably leads to loss in rainfall and attempts at reforestation have largely been ineffective due to the introduction of inappropriate species such as eucalyptus and acacia, which hinder rather than restore ecological balance. The famous backwaters are not immune to environmental damage.  The degradation in the mountains has resulted in rivers polluted by silt and industrial effluent also takes its toll; killing fish and presenting significant health risks.  Many wells have become waste tips, causing serious ground water pollution and leading to an inadequate supply of clean drinking water. The assessment of river such as Chalakudy, Periyar, Muvattupuzha, Meenachil, Pamba and Achenkovil indicates that the major quality problem is due to bacteriological pollution. The ground water quality problems in the coastal areas are mainly because of the presence of excess chloride.The chloride concentration >250mb/l was detected in the well water samples of Azhicode, Kakkathuruthy, Edathinjil, Kadalundi, Chellanum, Nallalam, Mankombu and Haripad. in Alappuzha district, flouride concentration in the pumbing wells was observed to be high.Open well of Kerala are under threat of bacteriological contamination.In Kerala about 60% of the population relies on ground water for drinking.At the same time studies have shown that faecal contamination is present in 90% of drinking water wells.

Coastal erosion is altering the seashore landscape and putting populations at risk. Over fishing, with the introduction of trawler fishing in the 1950s, is affecting the economy and health of the local fishing community. Kerala is one among the most thickly populated region in the world and the population is increasing at a rate of 14% per decade.As a result of the measures to satisfy the needs of the huge population,the rivers of Kerala have been increasingly polluted from the industrial and domestic waste and from the pesticides and fertilizer in agriculture.Industries discharge hazardous pollutants like phosphates, sulphides, ammonia, fluorides, heavy metals and insecticides into the downstream reaches of the river.The river periyar and chaliyar are very good examples for the pollution due to industrial effluents. it is estimated that nearly 260 million litres of trade effluents reach the Periyar estuary daily from the Kochi industrial belt

As one can read on the start of the article. We are having the 11th Kerala Environment Congress. That means the problems and issues which have been raise in the above paragraphs have been flagged as many as 11 times over!

How many chances would a boss give to his employee. A Father to his Son, to correct an error? Yet we keep mum on the abuses we have been meting to our Mother Earth.

The many of the problems and issues which Kerala is facing today would perhaps be very soon taking away the title of – God’s Own Country and make it..

God’s Forsaken Country ! Unless we make the changes Now !

And the changes must reflect in the life-style of the people of Kerala. Unless the Civic changes happen in the physiological level of the populace mere reports and laws would just not be adequate to improve the disasters which are soon to manifest in a much larger scale than presently perceived.

Water, Energy, Ecosystems and Biodiversity are affected directly by the way we create our Habitat.

Haphazard Urbanization of sleepy villages, with copy-cat Buildings as designed in the West and Middle East which are not Climate Responsive in the vernacular context, compounded by setting up of Industries; in hereto Agricultural and Forest lands makes Disaster Management during Weather Extremes a severe challenge. Due to weak implementation of Education & Communication skills there lack of understanding of Legal and Policy Aspects. The continued failings of which would impact the Tourism Industry, Marine and Coastal Ecosystem and most importantly on Agriculture and Food Production!

Food is the primary source of Energy for Human. Without Energy life can’t exist. So let us probe into the ways we can tap into creating of Energy – Electrical & Mechanical; which is the primary driver of  civil development while maintaining the ecological balance to have the perennial source of food with is a life source !

Kerala is blessed with a few unique backwater system, which makes it a prime area to use the latent energy this has. That is micro-hydle systems. But we shall come to this later as there would be challenges to this. Moreover we need to stitch together a basket of solution to arrive at an optimum solution by inclusion of Wind and Solar!

Let us therefore explore through data that is available from various sources and start with the least used one –Geothermal

Estimation of geothermal gradients and heat flow from Bottom Simulating Reflector along the Kerala–Konkan basin of Western Continental Margin of India ( by Uma Shankar, N. K. Thakur* and S. I. Reddi of National Geophysical Research Institute, can be read here).

Geothermal power plants operated in at least 24 countries in 2010, and geothermal energy was used directly for heat in at least 78 countries. These countries currently have geothermal power plants with a total capacity of 10.7 GW, but 88% of it is generated in just seven countries: the United States, the Philippines, Indonesia, Mexico, Italy, New Zealand, and Iceland. The most significant capacity increases since 2004 were seen in Iceland and Turkey. Both countries doubled their capacity. Iceland has the largest share of geothermal power contributing to electricity supply (25%), followed by the Philippines (18%).  ….

India has reasonably good potential for geothermal; the potential geothermal provinces can produce 10,600 MW of power (but experts are confident only to the extent of 100 MW). But yet geothermal power projects has not been exploited at all, owing to a variety of reasons, the chief being the availability of plentiful coal at cheap costs. However, with increasing environmental problems with coal based projects, India will need to start depending on clean and eco-friendly energy sources in future; one of which could be geothermal. – (See more at: )

The Costs of a geothermal plant are heavily weighted toward early expenses, rather than fuel to keep them running. Well drilling and pipeline construction occur first, followed by resource analysis of the drilling information. Next is design of the actual plant. Power plant construction is usually completed concurrent with final field development. The initial cost for the field and power plant is around $2500 per installed kW in the U.S., probably $3000 to $5000/kWe for a small (<1Mwe) power plant. Operating and maintenance costs range from $0.01 to $0.03 per kWh. Most geothermal power plants can run at greater than 90% availability (i.e., producing more than 90% of the time), but running at 97% or 98% can increase maintenance costs. Higher-priced electricity justifies running the plant 98% of the time because the resulting higher maintenance costs are recovered. – (See more at:

Next, let’s look at Micro-Hydle-

A study sponsored by the Science, Technology and Environment Department (STED) and conducted by the Centre for Rural Management (CRM) has found that a whopping 870 households in the district are served by micro-hydel projects. The study also brings out some interesting features of this unique initiative as also underscores the need to develop a support base to improve the efficiency and efficacy of these units. A typical micro-hydel project consists of a source of water, often a stream, or a storage tank or a check-dam made of either jungle stone or concrete, a plastic or PVC flexible hosepipe and a rewound bike or cycle dynamo which acts as the generating system. The average installed capacity of the large majority of them remains below 150 Watts an hour. This is enough to meet the lighting needs and also for operating a radio, tape recorder or television set. Nearly half of these units provide power to the consumers for 12 hours a day and one-fourth of them ensure round-the-clock power supply. Moreover, 52 per cent of these units provide round-the-year power supply. (read more)

While Solar and Wind have already stabilized in the state, what is required is that the Building industry adopts Renewable Energy in toto. The method should governed by sound scientific advice which should be the guiding principle of framing the Development Control Rules of each zone in the Urban planning.

What is true for the Goose may not be for the Gander. Thus when market forces especially the copy cats with baser understanding solicit business within the RE basket; in their enthusiasm, they spoil the market for serious players either by under delivery or corruption in methods. The problem is further compounded when “hobby builders” {a one-time player, usually with lot of disposable money and zero discipline; usually plays a spoiler for developers} with zero scientific understanding opt for L1 (lowest one) all products. As the specifications of such products do not and can’t match the originals; they fail.

This not only leaves Kerala with badly designed buildings, with ugly façade completely in contrast to its serene backwater surrounding; but also energy intensive with falling products over-time. The common man, un-schooled in the methods and confused with the constant pull of identifying more to an imported Western Culture than the sound vernacular life-style are ending up as the final looser in the game.

And the biggest loss is to Sustainable Energy methods. Which could be very well possible if laws are legislated to utilize hybrid RE solutions with sound building materials and design.

Green Business Idea : Using Manpower & Ox-power to generate rural electricity

Green Business Ideas needn’t be about multimillion dollars of earnings. Although that kind of money does impact lives and can bring in sea-change in thoughts and actions much faster; simple things which look towards the rural landscape should also matter where the earning may be more if the latent advantages are explored. It is also important to indigenise them to the local needs. We would discuss  ideas which belong to different countries but each can work in various Nations. Perhaps it would be the best BASIC country collaboration ever towards sustainable living.

Beginning by mentioning the superlative program hosted by CNN on sustainable living especially the Eco-Solutions  program where it was shown that, water hyacinth a bane for Africa ( & Asia) could be exploited to created products one would usually associate with bamboo or jute. Although weaving with water hyacinth would be natural in the South American countries, attempting to find its commercial use in Africa is indeed wonderful. While the botanists and environmentalist may not agree, citing the commercialization as a bane to their effort to eliminate the evasive weed; one while agreeing to their line of thought could differ in the approach.

English: Water hyacinth

Water hyacinth (Photo credit: Wikipedia)

The reason water hyacinth does not grow uncontrolled in the South American continent is because it has natural enemies which keeps it in check. Without such natural control available in the Asian & African continent the water hyacinth has wrecked havoc to the water-bodies. But now the biggest “natural” enemy to everything natural in this planet the honourable homo sapien; once they taste the commercial possibilities of any living or non-living material on Earth, one can bet their last dime that ‘extinction’ is not far away. Therefore one should not worry too much in supporting the poor African women in their attempt to commercialize the water hyacinth. Given the right incentive within a span of 10 years it would become less of a menace; not requiring grants from the UN to keep it under control and more of an opportunity to uplift the poor. If we attempt to think out of the box, sustainable solutions would be easier to come by. And the much needed grants could then go into attempt to rectify wrongs for which easier answer are yet to be found. It is therefore encouraging to see the USA come up with a process to produce Ethanol form water hyacinth at Lake Victoria in East Africa ( vindicating my article –The USA has given some of the top inventions to abate Climate Change.)

It is known to very few that Water Hyacinth can be used to produce Bio-fuel, which can then run a generator to produce electricity. Research on this has been happening across Nations including India, yet not enough media focus and awareness is created to bring it to the grass root level, where it would start to make a difference.

Recently, Oxfam has claimed that the lifestyle of the Maasai tribe in Africa should be embraced as a response to climate change because of their ability to farm in deserts and scrublands.Many Maasai tribes throughout Tanzania and Kenya welcome visits to their village to experience their culture, traditions, and lifestyle. In these tribe cattle plays a very important role too.

There is a great debate in the west about GHG emission form cattle, which is mostly reared for production of beef. With many becoming vegetarians and vegans the debate on consumption and rearing of cattle is still on with respect to their contribution to Global Warming. Those who may not know, in India  practising Hindus consider cattle as sacred. The word “Panjerpol” means an old home for cattle. While the word “Gaushala” denotes a dairy farm. Panjerpol is where devout Hindu’s like to see the cows to go, when their useful life as a milch cow or an Oxen ends, so that they can spend the remainder years in comfort. The charitable trust which I visited is run by some of the most successful businessmen in Pune, Maharashtra,India whose vision is exemplary. Considering every cow as Kamdhenu and all bulls as Nandi the teachings of sustainable living is practised even now.

In the day and age of increased awareness of the benefits of natural fertilizers,using  Cow Manure Fertilizer For
Growing Vegetables, – supply the best bulk form of organic matter to the garden. The fantastic soil conditioning ability of cow manure due to the amount of quality organic matter, that no processed fertilizer can match, is reason enough to use cow manure fertilizer whenever possible to the garden. The soil amending properties of this really great natural fertilizer has to be used to be properly appreciated. In another article Cow Urine Can Cure Many Diseases, the author an Ayurvedic Physician, from Gujrat goes on to say – …The analysis of cow urine has shown that it contains nitrogen, sulphur, phosphate, sodium, manganese, carbolic acid, iron, silicon, chlorine, magnesium, melci, citric, titric, succenic, calcium salts, vitamin a, b, c, d, e, minerals, lactose, enzymes, creatinine, hormones and gold acids.Cow urine treatment and research centre, in Indore (Madhyapradesh, India) has conducted a lot of research in the past few years and reached at the conclusion that it is capable of curing diabetes, blood pressure, asthma, psoriasis, eczema, heart attack, blockage in arteries, fits, cancer, aids, piles, prostrate, arthritis, migraine, thyroid, ulcer, acidity, constipation, gynecological problems, ear and nose problems, abortion and several other diseases. Cow is a mobile dispensary. It is the treasure of medicines. The cow urine therapy is capable of curing several curable and incurable diseases. The holy texts, like atharva veda, charak samhita, rajni ghuntu, vridhabhagabhatt, amritasagar, bhavprakash, sushrut samhita contain beautiful description about these things. It must be noted the late Prime Minister of India Shri Morarji Desai advocated Ayurvedic treatment similar to the one mentioned.

The above sets the stage across two continents on the importance of cattle and hyacinth as two factors which can play an important role in sustainable living in rural areas and thus advocates one of the agendas of the UNFCCC charter.

OX-Driven Electric Generator

The same amount of difference it would make, should the poor and marginalised farmer in India use his oxen to produce electricity. This is yet another aspect I understood on my visit to the Panjerpol near Pune. The article Ox-driven generators set to solve power crisis- BIT Mesra’s non-conventional energy gadget promises to steal show at Udyog Mela reads – An oxen-driven generator set, developed by BIT Mesra’s mechanical engineering department, is set to draw crowds to the forthcoming Jharkhand Udyog Mela 2008 at Morabadi grounds.BIT Mesra has booked a stall in the 11-day fair slated to start from November 15. The fair promises to be a good platform to inform the rural masses, NGOs and, most importantly, agencies working in the field of non-conventional energy about the importance of pollution-free power generating machines. A single unit of such a machine would be able to provide power to at least eight households.

This actually complements an article in another blog Engineering for Change which has devised the same idea by using bicycles –This innovation is one of our Promising Prototypes of IEEE’s Global Humanitarian Technology Conference in Seattle. Bike-powered electricity generators are a practical solution for Indian households. Surveying the country’s energy landscape, with its tight living spaces, expensive land, and far too many people for the power the country produces, bike generators make sense. Venkat Natarajan and his team at Intel Technology India in Bangalore came to that conclusion and they are testing their own low-cost designs.

ISCKON ideas

Developing Green Business Ideas which actually impact the lives of the Undeveloped or the Least Developed Nations must be given priority and WRI, CAN-International, Greenpeace and the likes  should try to make this as an agenda to be showcased at the next UNFCCC meet in Europe. As I have advocated always, it is not important whether we are aware of the possibilities, it is important that the poor and the needy are given the opportunity to exploit so. Water hyacinth covers the serene Vembanad Lake,is as recent a news as October 2012 whereas Biotech Students to Produce Alternate Source of Energy in Surat, published in June 1, 2011 pre-dates the problem taken up by the Times of India news. While BIT Mesra’s Ox-power electricity was showcased in 2008. Actually if one researches further this concept was already in place way back in 1985 and finds mention in Prabhupada News. Had it been encouraged and popularised by the Union and State governments in India, THE GREAT INDIAN BLACKOUT OF 2012 might have been averted. But sensible thinking and foresight is not an Indian thing. We are conditioned for lethargic and knee-jerk administrative reactions.

It is important for the UN to seriously consider taking up a dedicated media space to beam down relevant news and information, as mentioned above on a  24x7x365 basis around the world much like the popular Discovery or National Geographic TV programs. This would at least enable a ground-swell which may see some change for the better in the Developing and Under-developed countries where administrative apathy is rife.

How difficult is it for the media moguls to partner with the UN to launch such ground breaking idea? Something that would benefit the world and encourage people to people contact, thus bringing unto fore new ideas which could perhaps have commercial value? In many of the You Tube links attached to this article one can see so many home-grown ideas which can not get much traction due to want of audience. Some die out simply because the immediate society has no need of it, while it could have been a game changer a continent across; it may perhaps save lives. It can happen even now, in fact it must.

Most of India’s 20 nuclear reactors are on the list of the most unreliable 50 in the world, and villagers near the Tarapur plant have been bearing the brunt of after-effects of radiation. In spite of their complaints, all they’ve got from the govt is assurance of reduced exposure, which is no less risky, finds Dilnaz Boga. Poonam Hambire, a resident of Ghivali village, 12km from Boisar in Thane district, is at the forefront of the anti-nuclear agitation against the Tarapur Atomic Power Station (TAPS). “Women have to come forward as false cases are slapped against the male protesters in Tarapur,” she alleges. Her village lies within the 1.6km radius around one the country’s oldest nuclear reactors built by General Electric in the 1960s. It’s the same model as Japan’s Fukushima reactor. The effects of radiation are obvious in every home not only in Ghivali but also in the neighbouring villages.At Hambire’s home, her eight-year-old nephew’s garlanded photo adorns the wall. “He died of lung cancer, but we couldn’t get his medical reports from the government heath centre. It’s hard to talk about it as his father who is employed at the plant will lose his job. None of the sick villagers get their medical papers,” she claims.

The very argument that India needs to develop and maintain costly Nuclear plants, pales in comparison to the fact that using simple tools, the country under its NEREGA mission can utilize only a fraction of the allocated Nuclear development money and yet bring about enormous social benefit. The most telling; India has unemployed youth in villages who could if given a chance, pedal for 24 hours a day in shifts to continuously produce electricity. Which not only could then be stored and then evacuated into the grid for transmission and distribution but the labour could be paid for by the power companies.

As per the survey conducted by Labour Bureau of the Government of India, 40 Million are unemployed with an Unemployment Rate of 9.4%. The survey was conducted in 28 States/UTs spread across the country in which about 99 per cent of the country’s population reside. It estimates that the population of the country is 1182 million with 63.5% in the working age of 15 – 59 years, however, not everyone who is in the working age is interested in joining the work force, so the worker population ratio is much lower. There are an estimated 238 million households, of which 172 million are rural and 66 million are urban. Out of the total population of the States/UTs covered, 872 million persons (73.8 per cent) live in rural areas and 310 million persons (26.2 per cent) live in urban areas.As per The-Pedal-A-Watt-Bicycle-Generator an average rider will produce between 125 and 300 watts. So even if we consider one-third of 872 million people, the mathematics works out to be a decent amount of power generation + employment scheme wrapped into one. Will the Governments listen ?

Renewable Energy – Empowering Women & Saving Forests.(Redux)

During the recently concluded UNFCCC , COP 17 at Durban, that Climate change is a clear and present danger with Humankind pushing the limits of the Earth’s ability to cope with man-made pollution, was well documented by each Nation which spoke at the Plenary. And it was underscored with a grim report by the IPCC -4th assessment draft.

English: Adapted from a portion of Figure 1 in...

The year 2017 from where Human Economic progress will be trapped into a high carbon growth, which would compound and complicate the situation into a series of worst case situations year on year, each year causing great socio-economic suffering. The Stern Review details it for those who want to know more.

It is also mentioned, the worst of Climate change, caused due to unprecedented pollution the Human race produced in its quest to find a “safe – healthy – prosperous” life style; would affect those who neither had/has the means nor the thought process to live such life-styles; the indigenous people in the Brazilian rain-forest, the ethnic groups in wild and still  beautiful  and untouched Africa and the “poor” Nations and  economically weaker class of the societies.

While it is true that when one measures “development”  through the all-pervasive Capitalist Economic theory the World follows in its trade; the definition of poor would be a Man or Nation with no “money”, “cash” or whatever the experts like to call it. However today, one must pause and think on the terms “Rich” & “Poor” in the Climate change context.

Fresh Air, Clean & Sparkling Rivers, Beautiful Blue Sky, Lush Green Meadows, rich and varied Flora & Fauna are (strangely! – they don’t have the money to pay for such nice things, one might say ) with the POOR and UNDEVELOPED or UNDERDEVELOPED Nations, States, Provinces.

And what is most striking is that the RICH just don’t have it around them anymore. They need “treated & bottled”  Water, “filtered and air-conditioned” Air;  Zoos, which one needs to drive down ( provided one is in town/ else a planed tour itinerary during holiday season ) and an “all expenses paid” incentive ticket  to fly to these very underdeveloped/undeveloped  provinces & Countries to have a glimpse of the Blue Sky. Even virgin snow is hard to come by as by morning layer of sooth from Car exhaust ruins its colour.

It’s perhaps time that the UN & IMF, World Bank and those snooty Credit rating Companies, redefine which are the Bankable and Rich Nations.

Having said that, let the present so-called “Rich & Developed Nations“, be pressured by the right thinking citizens of those countries to save the very things they all want – Safe, Healthy & Prosperous life-style. And we just have SIX years  left to move the clock back-wards to meet that.

So what is it, in my opinion that needed to be done ? Simple, help the poor with their livelihood . Each day thousands of Women & Girl Child walk miles to fetch potable water & fire-wood. This happens in almost all South Asian & African Countries. It perhaps true for parts of South America too.

Many sea /river societies in Africa find sustenance through trade in Fish. The big and fresh catch is usually traded with the agents of Multi Nationals for pittance. The smaller catch is then sold in the local market, where it’s “smoked”  over burning wood. This practice over the years has decimated the forest around these societies. And many such examples have been documented across nations. Soon even these Least Developed Nations and societies would have no tree cover, being poor and economically weak finding the right solution would not be  easy. It would be next to impossible and the first of Climate Change Refugees would be getting ready for exodus, creating further aggravation.

But among all these gloom, there is hope. A ray of hope and a whiff of opportunity – Renewable Energy; namely Solar & Wind.

With the Green Climate Fund, a nascent reality; the LDC’s must create Program of Activities which is similar to what is now on going in India. TERI the think- tank institute headed by Dr. Rajendra Pachauri himself, has a program called “lighting a billion lives”. Here Solar powered lanterns are given to villages across India.

Gaushala, Goshala run in Nabha and its attache...

Earlier on India has/had a program under which Bio-gas which is produced from cattle manure ( Gobar -gas ) and piped  into homes for cooking. Now this is a finite resource because it is quantity dependent. It is therefore successfully implemented in villages which have cattle rearing as their primary business. In the State of Gujrat, India; its a great success, as AMUL created a business revolution around dairy and animal husbandry is a roaring business there.  However not every village can have cattle which would be producing to fulfill the requirements of energy for the entire village. Therefore the use of RE mostly Solar, or a Wind + Solar Hybrid could be the solution for each and every village. Not only in India but in Africa &  other countries too. By devising a Solar Tree ( roof top if applicable or possible  ) and drawing cables to each and every house hold in the village, electricity could be provided. Add cheap yet sturdy induction stoves and you are giving these societies a chance.

Why induction stove one may ask. Simple, as per the report from the Department of Energy United States, an induction stove is nearly 90% efficient in sending the heat where it is required the most – to cook the food. Whereas in a butane / propane , the gas we find in LPG cylinders, only 40% is efficiently used for the purpose of cooking. The rest heats up the stove, pan and the air around the flame.

Now considering that 1 kiloliter of LPG = 7.4 KWHr ( kilo watt hour) of energy and 1 kilogram of LPG = 12.68KWHr. And BTU ( British Thermal Unit ) a measure to calculate heat. Lets look at an example given below to support my idea of a “Solar Stove”.

Domestic gas in India contains – 14.2 kilogram = 180.05 KWh of energy

BTU/Hr = 180.05 x 3412= 614330.60 BTU/Hr

Gas heating efficiency is 40% only. Therefore 40% of 614330.60  =  245732 BTU/hr is actual usage from one LPG cylinder.

Induction heating efficiency is 90%.

Say  a SPV of 2kWp x 5 solar hour  = 10kWh, of energy. ( In India we have an average of  5 hour of good Sun-shine ) which can be stored.

Now if we use an induction stove of 2.2Kw rating and draw the solar energy

Induction of 2.2 kW= to a gas burner rated at almost 16,000 BTU/hour; ( Refer:Induction Cooking:Selecting a Unit )

Therefore total energy received per hour = 10 /2.2 = 4.5455 x 16000 = 72,728 BTU / Hour is actual usage.

Now any expert would tell you 72,7288 BTU is a lot of cooking heat with a very nominal drawing of energy.

a 30-inch four-element induction unitThe rule of thumb from gas-energy values: induction-element kW times 7185 equals gas in BTU/hour.

This is just with a 2.2 Kw induction stove, naturally a higher rated induction hob would provide far more energy.

The least-expensive 30-inch (four-element) induction cooktop has:

  • a 1.3-kW small element (between 9,000 and 9,500 BTU/hour),
  • two elements of 1.85 kW each (well over 13,000 BTU/hour), and
  • one element of 2.4 kW (over 17,000 BTU/hour).

The least-expensive 36-inch (five-element) induction cooktop has:

  • a 1.2-kW small element (8,500 BTU/hour),
  • a medium element of 1.8 kW (13,000 BTU/hour),
  • a larger element of 2.2 kW (16,000 BTU/hour),
  • and two elements of 2.4 kW (over 17,000 BTU/hour).

The very highest-power gas burner to be found in the residential market is 22,000 BTU/hour, and that’s a sort of freak monster, whereas a 3.6-kW and 3.7-kW element–which is around 26,000 BTU/hour of gas!–is found in many induction cooktops.

From the above calculation one can see that at village level where food is only cooked for sustenance, the energy used by each house hold would be at a minimum. If the Solar panel & stove is sized properly as per the societal needs in each society  across Nations, two most important changes would perhaps take place.

1. The Girl child & Woman would no more need to chop down trees for fire-wood, thus help heal the immediate environment.

2. No smoke from fossil fuel would be emitted into the atmosphere.

So this concept if implemented rightly, might just begin to turn the tide as Worldwide some 2.7 billion people rely on traditional biomass for cooking and heating, and 1.4 billion have no access to electricity.

So what’s with the electricity? Well if the 1.4 Billion were never introduced to the  oil and coal based electricity we would to Earth that much good. And now that we know the effective use of a new kind of Solar Stove; with cooking time reduced and need a minimum, may be some of that Solar power from the solar tree could light up a LED lamp in the village home.

And if we bring it to the cities, with the price of commercial LPG at Rupees 1600 / cylinder of 19kg. We may find some economics in this too, while reducing the subsidy burden for the Government.

Are the signatory of Kyoto  Protocol listening?
