Monday 22 Feb Visiting Sardar Patel College

23 02 2010

After a weekend of acclimatization, Monday was the day of the first testing. The three of us, visited the Sardar Patel College of Mumbai, where Yash finished his bachelor. There, after meeting the director of the mechanical engineering faculty and some professors, we installed our prototype on the solar cooker owned by the college. We spent a full day on the terrace of the faculty, trying to get some measurements from our system.

We also painted the pressure cooker black, using a mat black spray to improve the heat conduction. However, at the end of the day, we couldn’t manage to get results, because the water didn’t reach boiling temperatures, and the system didn’t manage to pressurize. We thought that this was probably due to the not ideal weather conditions. The day was cloudy and slightly windy. We also figured out, that the solar cooker was old and the mirrors had deformed resulting to the change of the focal point. This was confirmed also from the manufacturer of the solar cooker, Mr Gadhia after a phone discussion we had with him.

Other small problems we encountered were leakages from the pressure valve as well as from the pipe connection between the two buckets, which we managed to solve until the end of the day.

During our staying on the terrace of the college, we had the opportunity to interact with many students, which visited our installation and were willing to learn about our product and technology.

Here, there are some photos of the first installation, more to come!





Namaskar from Mumbai!

23 02 2010

Its already the fourth day that we are here, but we have now realized how fast the time flies. The days in Mumbai run really fast, there is never enough time to do all these things that you would like to. A city of 13 million people which never sleeps. Anytime of the day roads are busy, people spring in the middle of the road from all possible corners, vehicles and mostly “rikshas” are moving like dodgems in a funfair and the shops seem that they never close. The extravagant honking from the vehicles reminds you that you are in a crazy place, or as indians prefer to refer to it: in “incredible” India. Every day we are getting more and more overwhelmed by the intensity of the images, sounds and smells we see when we are roaming around the streets. Rides in Mumbai can never be boring. It is always unsure when you will need to brake, close the car windows to avoid beggars, or be stunned from a cow that is walking or lying on the street. Mumbai is the city of contradictions. Two different worlds, the “high” and the “low” world, which manage to coexist, causing in the same time sad emotions when observing the social inequality and poverty. Photos are not enough to depict pictures, sounds and situations we experience every day and most importantly cannot illustrate our expressions and feelings after every cultural shock. Yash, patiently tries to explain everything we see around us, getting us every day a step deeper into the Indian culture. Surely, only now we fully understand the descriptions of Bauke, Anahi and Lisanne when they firt went to India, two months ago. Amazing experience as amazing is the country and the people here.

The second group is prepared for the trip!

18 02 2010

Tomorrow morning the second group, Yash, Valia and Johan will travel to India to test the design. We will keep you informed via this blog!

The main goal of our visit is testing the water device. The last days we decided to build up the system from scratch again to be able to make good improvements. So our days excisted of a lot of manufacturing in the working place of the TU and now everthing seems to be working! The system is qualitativly well build, so it should give trustworthy results. Now the system is being filled up with towels and socks, and put in our bags in parts.

We are looking forward to the two coming weeks and are thankful for this opportunity to test this device, learn a lot  and have a great fun experience.

You shall hear from us!

Product – Strength & Weaknesses

20 12 2009

In advance of the context research a product concept was made. In advance a concept was designed to fit the need of the rural areas of Konkan concerning clean drinking water.

With this concept in mind the context research was set-up to view if this product could fit the context.

A solar water still was designed. It is a double-staged distillation tower added on top of an pressure cooker. This pressure cooker is heated by a solar concentrator: the solar cooker.

[Picture]

As a result of the context research the product concept strength and weaknesses are concluded.

These strengths and weaknesses are only product focused, whether the product will fit the market is excluded from these as there is concluded there is no real problem concerning clean drinking water in the rural areas of Konkan.

Strength:

  • Desalination of seawater as an alternative drink water source.
  • Use of existing cooking products
  • High potential for cultural fitting, modular fitting.

Weakness:

  • Expensive
  • Not user friendly (students)
  • High maintenance (to keep high efficiency)
  • Lack of solar cookers (Bapat, students)




Health – Dr. Kanikav

20 12 2009

Dr. Kanikav is a prive family doctor for the village of Devrukh (rural area of Konkan) at the local public healthcentre.

Visit to doctor

Common diseases in Devrukh he mentioned are the Cold and the Fever. Not different compared to the western society. Next to that he mentioned that there is some diria caused by bad food processing.

As Dr. Kanikav started 40 years a go in Devrukh without electricity, he said that a lot has changed. For the most the mindset of the people has changed. People take their symptoms more serious and therefore go sooner to the doctor.

According to Dr. Kanikav the water in Devrukh is clean enough to drink directly, though filtering is better. Because there are industries in the villager, there is also no source for contamination of the water.

Since 5-8 years the government of India has a new scheme. That supply potable water to everyone. This can be by grid, well, bore or if necessary by tanker.

Water – rural areas of Konkan

20 12 2009

Summary of our activities in the urban areas
We went to the rural areas of  Konkan for 5 days, to investigate the drinking water problems people have here. We were stationated  in the village devrukh to be precize. We have seen a lot in those days so fist a summary of our activities:

- We visited a ’Wadu’  (about 600 people) to see how these people get their water and how they use it.
- We spoke to one of the five members of the ‘Grandpatjati’ (that’s the council of wise men that every village has) about the way people use water.
- We visited a dam the goverment is making in this area. The goverment uses this water for the grid connections most people have in this region.
- We spoke to two poor woman who were working in the field, carring big pots of water on their heads.
- We visited a special village that is an great example of living in harmony with nature. We will wrote a seperate blog about that.
- we visited several wadus/houses close to the coast to see if living so close to the see gives water problems
- We visited a local public healthcare centre and we spoke to the doctor.

Summary of some interesting findings
Before we summarize the most important findings it is good to tell something about he housing situation in the rural areas. In the rural areas you have different types of villages. You have the ‘real’ villages (over 2000 people), you have the so called ‘Wadu’s’ small villages with a few hundred people and you have small settlements with just some houses. In the villages you mostly see real houses, on the farmland it is also seen that the small settlements exist out of cottages made out of plastic sheets, wood and stones.

Grid connection
In the real villages of Konkan all the people have a connection to the grid. Every month a fixed amount of money needs to be paid for this connection and you have to pay ones when you want the connection. This grid connection is a connection provided by the government and the water is coming from a big lake behind a dam the government has build here.

Private wells
You see that most of the people with some money also have there own well. The place we slept (Onest) had its own well for example and they used this water for everything. The grid water is only used for watering the garden. The cost for digging a well is between 20 and 40.000 rupees. If you want a well an engineer comes by to tell were to dig the well exactly and what dept it should be. Most of the time it’s around 300 feet deep.

Governemental wells
People with less money don’t have an own well. They use a public well made by the government. In the last 8 year the government provided a lot of wells in the rural areas so everybody has access to water. We have heard and seen that in the most unfortunate situation you have to walk for a bit more than 1km to reach a well, al the other people life closer to the well than that. When the ladies go to the well to collect water they bring water vessels with them. On the way back they carrie two of them on their head.

people drink the water directly from the well

We have seen two types of wells; old wells (called wells) and modern wells (called bore). The old ones are big open wholes (waterput) while the new ones exist out of a closed system (pipe and handpump)

Modern well (bore well)

Open well

Availability
In the konkan region the wells are filled with water all year long, they almost never dry up. This is because of two reasons. First of all there falls a lot of rain during the monsoon. Second, there are a lot of trees in this region that can hold the water for a long time. They make sure that the rain that falls in June and July will be kept.

There are many trees that can hold the water

There are some places in the konkan region with less trees and there the wells dry up some times. In that case the government comes with tankers filled with drinking water to solve the water shortage. So in general you can say that there is no problem in the rural areas of konkan if you look at availability of drinking water.

Quality
If we should believe the people in Konkan, the water from the wells is of really good quality. The ground filters the water naturally so it can be consumed directly from the well (no boiling or filtering). People avoid the use of parricides because they know it can contaminate the water. By accident we tested the quality of the water our selves as well. We drank a whole glass of water from the well of Onest (because we thought it was bottle water). We are still alive and kicking so we can say that the quality is good indeed.

Human errors
So if you ask us there are no big problems in relation to drinking water in the rural areas of Konkan. The only improvement we see is increasing the changes of human errors. As the picture showed, all the old fasion wells are big wholes in the ground. None of them is properly covered so all kinds of things can easily fall in. When an animal falls in for example the water will get contaminated. When something like this happens, the people will use chlorine drops to clean the water again. (the government has given all the villagers a bottle with chlorine for cleaning contaminated water)





Water – Example village

18 12 2009

On Thursday December 18th we went to ‘Dweger’. A village which is able to totally run on its own. We were shown around by Mr. Sadannand Bondre, which is an local agriculture expert. He helped to rearrange the village into an eco-village.

320 people
65 houses

The first impression of Dweger is its the immense greenness of the place. By a smart combination of water resources, vegetation and irrigration, the villages manages to stay green throughout the year. This system is fed by a river crossing all trice lands. Little dams here and there will stop the water for a sudden time to let it float into the rice lands. Next to that there is a natural pawn, which is groundwater which can be reached directly. This is the village’s source for drinking water. It can be consumed directly, though at the school they learn to filter it before drinking it.

Children are going to school 6 days a week, to learn about: history, personal hygiene, water, trees (they sang I beautiful song about not cutting down the trees) and all the rest that keeps the village into perfect eco-balance.

Water collection from natural source

This village is a good example of how to live a balanced life with nature.  Be a part of it and don’t destroy it. Vegetation is the key for keeping the ground hydrated. Though reality is different, even in this little town the population grew with 50% the last 10 years. Population growth is causing big changes on a national level.

Still this village is really inspiring, the way they treat their environment by for example learn the children to not cut down the trees. Next to that mr. Sadannand Bondre in cooperation with COL (Commonwealth of learning) helped to write a booklet about the village, with the subject of how to achieve this yourself.

Preliminary Conclusions

18 12 2009

Straight from the Rural areas of Konkan we bring you the preliminary results of the context research. The context research findings are concluded in 6 statements, each connected to a specific topic:

  1. There is a fresh drinking water problem in the urban areas of Konkan, but there are no significant problems in the rural areas. (water/healthcare)
    N.B. Coastal Areas of Konkan will be visited tomorrow, to get a better view. An local agriculture specialst described that salt water is coming more in land, with a growth of 100 meter each year due to the rise of the seawater level 

 

a.) Availability
        Due to overpopulation there are not enough water sources. (prof. bapat, students IDC, villagers)
b.) Quality 
        Illegal housing -> illegal taping -> cause for contamination (KEM Hospital)

Why is there no significant problems in the rural areas?
a.)  Just enough availability (hotel owner)
     1. Wells
     2. Governmental Grid (Dams)
     3. Suplly by Tankers (trucks)
b.) Quality is good enough 
     1.  Short connections (home sources of close by) Small chance of contamination: storage in closed pots. (villagers)
      2. Little chance for contamination -> no use of pesticides (Agriculture specialist)
      3. If there is awareness of an form of contamination, then chlorine drops will be used (freely provided by the government). (villagers)
     4. Boiling/Filtering is not a must due to natural filtrations. (villagers)

  1. There is a need for other fresh drinking water sources in Konkan (water) (Mumbai Times, Prof. Bapat, Agriculture specialist
  2. To make a product successful in India it needs to be ‘cheap’ (lifestyle)
         a.) Most of the people in India have little to spend: 140 Rp a day for a worker. (villagers)
         b.) People make a lot of things themselves. (photos) c. In relation to water people prefer to walk for some time for free well water, instead of buying it. Labour is cheap. (prof. Bapat)
  3. To make a product successful in India it needs to be functional & simple (lifestyle)
         a.) No rocket science (form follows function)
              i.) People do not use products they do not understand. (Prof. Bapat IT, Students) 
              ii.) Photo portfolio of products used in and around the house. (photos)
  4.  To decrease the contamination of drinking water the chance of human errors needs to be minimalized (healthcare) (Source: KEM Hospital)
  5. The use of solar cookers is rare in Konkan. (lifestyle)
         a.) Does not fit the Indian cuisine (Students, Prof. Bapat)
         b.) There is not enough space nor sunlight in the Urban areas (Students)
         c.) It is too expensive (villagers) N.B. Government has a subsidy policy on solarcookers, but the villagers do not know how to subscribe for it.




Lifestyle – mini Slum

15 12 2009

Very close to the main gate of the IIT campus you can find a mini slum. It is so strange to see that rich and poor live and work so close together.

Imagine this being your grand parents…

Very sustainable; rubish gets a 2nd (or 3th, 4th) life

keep smiling
