Robots- need for research and use in India

14/01/2017

One often hears news about robots performing functions of human beings in countries like Japan, US, Germany, South Korea, China and even in small countries like Denmark, Sweden, Finland, Hong Kong in factories, restaurants, hospitals, transport equipments  etc and there is hardly any news about the manufacture or use of robots in India. It is true that in India there is high unemployment and introduction of robots will increase unemployment. But development of robotic science/technology cannot be neglected, and India should not lag behind even small countries. Indian government  should set up robot research institutes and fund research by private establishments including industry. Even if unemployment is high, there are areas where there  is danger to humans in working. India should think of immediately importing/ developing robots for use in fire fighting, rescuing people from floods, rivers and seas, use for certain works in mines, in matches, fireworks,  and chemical factories and other hazardous places including in factories like cement, thermal and atomic power stations et.


Desilting lakes and rivers

13/12/2015

Every year silt is deposited in the lakes and rivers. As the silt level increases  the quantum water the lakes and rivers hold decreases. This will naturally lead to floods if the rain is heavy. In the past, farmers and others used to remove soil from the lakes for use in fields and the lakes were  desilted without any effort  or expenses from the government. Now there are avoidable restrictions on removing silt from the lakes.  If restrictions are removed or reduced, many brick kilns will deepen the lakes enabling the lakes to hold more water, thus minimizing /preventing floods and providing more water for irrigation. As regards rivers, sand is deposited in the lakes by the water coming into the rivers. There are more restrictions on removal of sand from rivers.  Government should consider removing these restrictions or   selling the silt and sand to the consumers without any hassle.


RESEARCH ON CLOUDS,WIND AND RAIN

09/09/2014

Recently there were moderate to heavy rains in certain parts of Tamilnadu but in certain other parts like in many places in Dharmapuri district there were no rains. Hewever, one could see clouds every day. There are general theories on how clouds are formed and how it rains.

Cloud seeding is done by many countries including India for inducing rainfall. Now what is required is research on reducing the cost of cloud seeding.

There is also need for research on rainfall when there are no clouds over the area where rain is desired. There should be research on moving rain bearing clouds from where ever they are to where ever rain is required. The cost should be affordable. There are generally more clouds over sea than over land and rain is more required over land than over sea. During day time winds blow from sea to land and vice-versa during night time. But this does not happen some times and rain bearing clouds are not moved by winds to land during day time. Now the research should be on moving clouds from over sea to land at affordable cost.If the cost is affordable, then the clouds can be moved also from places where the rain is causing floods to dry areas. Considering the amount of time,energy, money needed to mitigate the effects and contain damages of heavy floods, expenditure on research on moving clouds is worth spending.


India- urgent need for water diversion project

12/12/2013

India-water diversion project

China has embarked on a water project costing about Rupees 4,00,000 crores for diverting annually about 45 billion cubic meters of water from water surplus southern province to water deficit northern provinces. This is only about 7- 8% of the annual discharge of water from Ganges river into the sea at the rate of about 650000cu.ft or about 18860 cu. meter of water per second.

India should undertake such large project for diverting about 50 billion cubic meters of water from Ganges river in the north to the southern states to minimize floods in the river and to irrigate the land in the water deficit states in the south. This project will widen and deepen the knowledge and engineering and technical skill of the officers. Since this is a huge project, it would be necessary to hire the services of experts from developed countries who have expertise in constructing long tunnels etc. There will be scope for hydro-electric power projects, the river/canal transportation, setting up projects requiring large quantity of water etc. The cost of the project will be very high and therefore should be undertaken as a joint project of the central and concerned state governments. However, as the project will take may years to be completed, the annual allocation for the project may be manageable.

This project was talked of sometime earlier but was not pursued. There was opposition to the project from leaders like Lallu Prasad Yadav of Bihar. Making all the stake holders to accept the project is a huge task. But there will be lesser problems if the project is taken up earlier.


India’s role in world affairs

03/10/2012

India is at present the second largest country in the world with every sixth person in the world being an Indian.In the next 10-15 years India will be the largest country with over 20% of the world i.e every fifth person in the world will be an Indian. At present India’s contribution to the world GDP is about 6-7%,being the third largest economy in the world. In the next 10-15 years,India’s share in the world GDP may go upto 10-12%, though it may continue to be the third largest economy. In this position,India should not contiue to take the stand that it does not want to interfere in the internal affirs of other counries. It should take active interest and major role in ensuring peace in the world and in helping poor countries not with materials but by giving consultation, technology, and if necessary loans.In particular, in consultation and cooperation with large countries like China,USA,Indonesia, Brazil etc India should strive for:

i.dissuading counries like Iran, Israel and North Korea to give up plans even for developing nuclear technology even for peaceful purposes,as this is the first step in the efforts for nuclear weapons

ii.persuading countries to take full responsibility for dismantling terror outfits and eliminating terror from the world. Terrorism has been one of the causes for world economic recession, as a lot of manpower is wasted in trying to preven terrorist activities

iii. being the largest country,it has to take responsibity to contribute to the health of the world population. towards this,India has to spend more, on medical research and spend more on establishing super speciality hospitals,so that small countries which cannot afford to establish the same can utulise the facilities in India

iv.India should increase its food production by 200-300% so that countries affected by natural calamities like floods, drought, earth quakes etc. can be assisted.

v.India should take initiative in brokering peace between warring countries or groups of coutries

vi.India should be the one which tables a large number of resolutions in UN organs like General Assembly, Security Council, specialised agencies etc.(It is taken for granted that by that time India would be a permanent member of the UN)

vii.India should spend much more on and expand its aciviies in the space, nuclear, ocean,heavy materials, renewable sources of energy, nano and emerging sciences as small countries will not be able to spend manpower and money on large projects and allow other countries to benefit from its activities in these spheres.


Forum for fair share of international rivers water

29/07/2012

China has a very large number of long rivers. A few of these rivers flow into other countries before joining the sea or other rivers. These countries are India, Bangladesh, Pakistan, Kazakhstan, Russia, Myanmar, Thailand, Laos, Cambodia and Vietnamt. The rivers include Brahmaputra and Indus. Every year China faces heavy floods and large scale destruction of lives and properties. Still China wants to build dams to divert water from flowing into other countries thus denying the neighbouring countries of their traditional share. There is no water sharing agreements between these countries and China is not likely to agree to enter into any such agreements.Therefore India, Bangladesh and Pakistan being large countries and are likely to suffer more if dams are constructed on the rivers coming to India and then to Bangladesh and Pakistan, should take initiative to form a forum of countries mentioned above to persuade China and also force them through international organizations and other countries to desist from diverting water flowing through their countries and to enter into water sharing agreements.


India- Land and Density of Population

13/08/2011

Excerptfrom “Simple Alternate Development Strategy” 1997

“Land and Density of Population

While in population India is the second largest, according to FAO statistics, in total area of land it is only the 7th largest… …However….. in 1991’…..India had 77% more ARABLE LAND than China, the most populous country…..It is seen from the above table that while density per hectare of arable land in India at 5.27 is higher than the world averge of 3.99 by about 32%, it is less than the Asian average of 7.51 by about 30%. Compared to more populous China,whose density is 12.39 per ha of arable land India’s density is just 32% of China.. In less poulated countries of Egypt Bangladesh,, Indonesia, Japan, South Korea, Malaysia Pakistan, former West Germany, UK, Italy and Netherlands, density per ha of arable land is higher than in India.Thus it is apparent that India’s density per ha of arable land is not at all high and hence reduction in population growth should not be a high priority issue for the planners at the moment. The high priority concern should be to provide employment to all able bodied ersons… However, as the land available for cultivation is limited, at some stage or the other the populaton growth has to be curtailed-if the growth continues at the present rate.But that stage will come not in 5 years or 10 years but in 50 years or 100 years i.e. when the population doubles/trebles but then, it is possible that new methods would have been evolved to increase the yield of foodgrains by 100% oe 200% or even higher…

As of now it is clear from the foregoing that India is not over populated …..If China with 93 mllion ha of arable land can feed 1.15 billion people, India with an arable land of 165 million ha should be able to feed 2.00 billion people, but the present population is less than one billion.

India should not treat the population as a liability. It is an asset which should be fully utilized. The casualness with which the authorities treat deaths due to disasters like floods, diseases, accidents can ultimately be traced to the attitude that lives of human beings are not very important……”

Though the figures have changed since 1991, the conclusion that India is not overpopulated remains correct. In fact it is supported by omythe fact that almost every sector of the economy faces shortage of labour. Of course, this is not due only to expansion of the economy but also to the fact that a sizable section of the population manage to live with working for 5-10 days a month with the free things they are getting from govenment.
