PC – Phone
[25]
During 2001 to 2004, I worked for a company called n-Logue Communications Pvt. Ltd. The company was focused on bringing internet based services to rural areas of India using indigenous low cost wireless technologies. Part of the National e-Governance Plan is to put 100,000 Common Service Centres (CSCs) in villages of India. The CSC is meant to be internet enabled to deliver a variety of services to rural areas. See http://www.csc-india.org/
For these CSCs to be exceptionally successful it really requires the Government to have a very strong, powerful and reliable information technology based backend to deliver all services to rural communities.
However what I learned during that period and subsequently is that the internet and Personal Computer (PC) are the real stumbling blocks for the success of information technology in rural areas of India.
This my list of 9 things that can go wrong
1) Connectivity today is much better than it was in 2004, but speed is still an issue.
2) Electrical power availability is a show stopper
3) The initial cost of all hardware, PC, UPS, connectivity, furniture is high
4) Most softwares require knowledge of English
5) Vernacular content is largely urban centric
6) There is no mechanism for rural needs/content to show up on the internet
7) Hardware malfunctions need specialised skills not available in rural areas
8) Software problems especially virus attacks cripple the PC on a regular basis
9) The keyboard is the worst interface for rural people to use.
If you consider the mobile phone, you will find that it is a solution for all the problems listed above. The greatest part of the solution is the voice interface. There are social enterprises using voice recognition technologies to act as the interface between the mobile phone user and a server at the other end of the line. Speech recognition in local language is the most advanced technology that can be used to serve rural folk. It does not require any pushing of buttons to choose number options. Customers don’t receive text messages, they receive voice messages. Complexities of illiteracy and innumeracy are removed by the most natural of interfaces, speech.
Mobile Health
[18]
The mobile phone has found its way into all corners of the world and very remarkably even to the poorest people in India. The mobile is now the platform of choice for almost every conceivable application. One of the latest gives regular updates on patients’ blood pressure.
“The HP Mobile Health Monitoring Solution offers just that, but without the need for users to visit clinics or hospitals to get their vital statistics read. Instead, it deploys a mobile device to monitor and record patient blood pressures around-the-clock and then shares that information in near-real time with healthcare professionals, wherever they’re located. Any anomalies in the users’ health data trigger alerts to the healthcare service provider.”
“In the trial, 100 patients from Frontier Healthcare are wearing HealthSTATS’ wireless BPro® watch-like monitoring device. HealthSTATS software translates the patient data into meaningful clinical readings, including 24-hour blood pressure and heartbeat patterns. The information is then relayed wirelessly to a centralized healthcare data repository powered by SingTel’s cloud infrastructure.”

This is just the beginning. A lot of research work is going on to develop a reliable and non-invasive blood sugar measurement system. Thus, two of the most prevalent causes of death (diabetes and heart attack) will be monitored and controlled in real time by health professionals.
Health- ECG for the poor
[13]
I worked for the Byrraju Foundation, Hyderabad between 2007 and 2008. During that time I met with many professionals in the Satyam Group of companies. B Swaminathan was one such professional whose dream was to bring complex medical diagnostics to the village in an affordable way.
Swami and I sat and thought about this and looked at all the resources available to us. This included 30 internet kiosks set up by the Foundation in 30 villages of East and West Godavari districts of Andhra Pradesh, Electro Cardio Gram (ECG) kits provided along with ISRO Village Knowledge Centre programme and a good enthusiastic team of medical professionals. Swami told me that he could get a tie up done with Narayana Hrudayalaya at Bangalore. Narayana Hrudayalaya would be able to look at an ECG output, make a diagnosis, suggest over the counter medication if required and what further action the patient should take. All of this within 15 minutes of receiving the ECG and for free.
We had to convince the management at Byrraju that we could make this happen at an extremely low cost to the patient and they agreed to let us do a pilot. The pilot was successful and we had pegged the cost of the test at Rs. 25/-.
Swami and I were delighted. Using the connectivity available in the internet kiosk, the low cost ECG kit supplied by ISRO, medical technicians available at the Foundation health clinics we were able to take the ECG readings of patients and send them to Narayana Hrudayalaya. Within 15 minutes we would get the response from Narayana Hrudayalaya. Rural people were at that point of time getting an expert opinion on their heart at a cost cheaper than any urban person.
The programme got Byrraju Foundation the Computer World Honors Program Award.

Why electric heating is silly
[7]
It is always annoying for me to see electric water heaters. The annoyance comes because in India we produce most of our electricity using coal. The overall thermal efficiency of a power plant running on coal wont exceed 30%. The electricity is transported over hundreds of kilometers (with a 20% loss during transmission and distribution). Then after many step down transformers (each with its on loss of heat) the electricity comes to your home. Now you attach a device that converts the electricity back to heat and that is your electric water heater. If you are not able to see that conceptually this a waste of a “good” resource like electricity, then I am afraid you wont like what I am about to say next.
There should be a move to ban electric water heaters across the country and the world. Electric water heaters waste electricity. They also waste a lot of good quality water as you wait for the hot and cold water to mix till it is the right temperature for you. In my house we have not installed electric water heaters. We heat up a small vessel with good quality water over a gas stove and then mix this in a bucket with cold water and get our desired temperature. It may be a bit inconvenient when there are many guests at home but it helps regulate water use as well. In Chennai good quality water is always to be conserved.
My work took me away from Chennai to Hyderabad and I was staying in a gated community that had ensured the houses had solar water heaters on the roof tops and also built a pressurized water system rather than one based on overhead tanks. The 16 months that I lived in that house were like being in heaven. The high pressure shower that very quickly adjusted its temperature meant an extremely refreshing start to the day and an excellent tonic before going to sleep. Our electricity bill would come to around Ts. 300/- per month since it was also fitted with Compact Fluorescent Lamps.
Biodynamic Chromatogram as an Analytic Tool
[6]
The use of chromatograms in Biodynamic Agriculture was supposed to show the presence of a spiritual component a “formative force”. The chromatogram is an image developed from an extract of substances like soil, dung or food using simple commonly available chemicals. (see http://www.biodynamics.in/chrom.htm )
I first saw the chromatograms at a Biodynamic workshop held at Kodaikanal, Tamil Nadu, by C Jeyakaran and friends. I was accompanied by Dr. K Perumal and we were both representing Shri A M M Murugapa Chettiar Research Centre (MCRC), Chennai. Perumal and I, were both fascinated by the chromatograms and we discussed the similarity of the technique with conventional chromatography. I suggested to Perumal it would be good to see how important soil nutrients like Nitrogen (N), Phosphorous (P) and Potassium (K) looked like with this technique.
Perumal kept working on this and a couple of years later after I had left MCRC we met again and discussed the technique. By then I was with n-Logue Communications Private Limited. n-Logue was putting up internet kiosks in villages and I was searching for special applications to put on the internet for the kiosks set up in the villages.
I suggested that Perumal should create a library/database of chromatograms. The IIT Madras had a bunch of researchers working on pattern recognition. If the chromatogram kits could be standardized then a chromatogram of the soil at a farmers field could be compared with images in the database using pattern recognition software through an internet connection at the village. The comparison and subsequent interpretation would be used to give guidelines on the quantity and type of nutrient the soil needed to become healthy.
These were just ideas we were throwing around at that time but Perumal continued to work on it and he even got research funding from Department of Science and Technology, Government of India. He worked and built a kit that gives repeated and reliable results. He also created a vast library of images. Validation of results used conventional techniques as well.
Today this technology is to be used to advise farmers on their soil nutrient requirements. Fo more information contact Dr. K Perumal (perumalk@mcrc.murugappa.org) at Shri AMM Murugappa Chettiar Research Centre. (http://www.amm-mcrc.org/)
Technology Challenges in Dairy
[5]
About 20 years ago my guru Dr. C. V. Seshadri was approached by a young and enthusiastic NRI who wanted to set up Institutes of excellence similar to the IIT’s (Indian Institute of Technology). These institutes would focus on information technology and were to be named IIIT (Indian Institute of Information Technology). The young NRI asked my guru what would be the pressing challenge facing Indian farmers that these Institutes could address. Without batting an eyelid my guru said every farmer wanted to know when his cow would enter estrous.
Much later I understood how useful and really important this piece of technology could be. Farmers who keep small number of cattle need many sources of income to make keeping cattle viable. Chief source of income is the milk. The milk is available as long as the cow is nurturing a young calf. For a farmer it is important to keep getting a yield of milk from the first calving. This means that after the birth of the calf and within a 2 month window the farmer would want the cow to be pregnant again. This is the tricky part. The estrous cycle is about 21 days long. There is a window of less than 6 hours and upto (sometimes) 24 hours within which insemination should take place. Otherwise the farmer has to wait for another 21 days. That means a 21 day loss of milk yield. (see http://beefrepro.unl.edu/pdfs/estrouscycle.pdf for technical details).
The first technology revolution for cattle was pioneered in India by Bharatiya Agro Industries Foundation (BAIF). “Dr. Manibhai Desai, a freedom fighter came to Urulikanchan near Pune with Mahatma Gandhi in 1946 to manage the Nature Cure Centre to promote community development and sustainable livelihood. Based on the successful experience, he established the Bharatiya Agro Industries Foundation (BAIF) and motivated small farmers to take up agro-based development, as their business enterprise with sound management. Later in 1989, BAIF was renamed as BAIF Development Research Foundation to re-focus on development research for rural prosperity. Cattle development was the initial preference to serve small farmers effectively.” (see: http://dev.ikf.in/baif/about_us_about_baif.asp )
BAIF is most well known for their Livestock Development programme. “This flagship programme, launched in early 70’s, is presently serving over 4.4 million families through a network of over 3500 cattle development centres spread over 70,000 villages in the states of Maharashtra, Karnataka, Gujarat, Rajasthan, Punjab, Uttar Pradesh, Uttarakhand, Madhya Pradesh, Andhra Pradesh, Bihar, Orissa, Jharkhand and Chhattisgarh. Each centre covering 15-20 villages in a radius of 10 km, is operated by a local youth, trained to provide services such as artificial insemination, pregnancy diagnosis, vaccination, minor veterinary care, forage production, good feeding and management practices. BAIF’s Central Research Station at Urulikanchan provides frozen semen produced from elite bulls of foreign and Indian breeds to these centres, apart from conducting applied research, technology development, training and supply of critical inputs such as cattle feed, mineral mixture and seeds of elite forage varieties.” (see http://dev.ikf.in/baif/our_programmes_livestock_development.asp)
With establishment of these centres, artificial insemination of cattle has allowed farmers to get their cows pregnant in the shortest time. However they must recognize that their cow is ready to be inseminated. A technology that would inform a farmer that his cow is ready for insemination would go a long way in reducing the loss of revenue from milk, and this is what Dr. C V Seshadri had said was critical to farmers. Any technologists readyto take up the challenge?
