Engineers hover over Tidal and Wave Energy

0
Water - A matter which is omnipresent in our blue planet has a very huge potential. It has a density almost 800 times more than air.

So Building a generator which could withstand the tremendous force generated by water has made it hard to develop the next generation of hydro power.

Till today the only way to obtain hydro energy is to build a dam across a river and harness it's energy. But building dams require huge amount of time and Money and they don't provide constant electricity and is dependent on rainfall.

Tidal Energy


Tidal energy one among the most predictable energy sources can be harnessed only through building massive dams which impend the flow of water till recently The Ocean Renewable Power Company (ORPC) developed a new type of Hydro Generator called the TidGen which can be placed at the bottom of a free flowing deep river or a ocean bay.

The Tid Gen sits at the bottom of the floor of a bay 60-150ft deep. It has Tear Foil Shaped turbines to rotate in single direction whatever may be the flow of water. A Magnetic Generator is connected to four of the turbines and generates upto a peak of  180 kW... But ORPC plans to build a 5 MW generator within next 2 - 5 years


2. Wave Energy

Wave energy are more stable than Tides and has a higher potential and are spread almost throughout the world. But they are more tougher and violent that a the generator and turbines has to be made with more stronger and tougher materials or else it will break. A London based company called 40South developed a new generator which smartly adjusts its positions to find the optimum conditions and will escape storms. The Generator's upper half is attached to a suspended platform and it's lower half is Fixed to the water bed.
40 South plans to build its first generator with 150kW capacity at Tuscany, Italy. Now they are developing a 2MW version to deploy at a Pilot - Wave Energy Park in India

Energy Tower

0
Energy Tower is a Energy Generation tower which uses the Heat of the external surrounding air to generate electricity in a Pollution Free manner.

So It's a way Generating green energy.

Energy tower is tall Hollow Cylindrical tower of 1000 metres high and 400m wide. It has provisions at the bottom to suck the hot air into it. A Water spraying system is located at the top of the tower. As Hot air is light denser moves up through the tower it is cooled at the top by spraying of water. The air now becomes cool and denser.
This Cool, denser and more weight air flows through the tower to the bottom it a small thunderstorm of air is created as the Hot air rises up at the same time.. This wind storm rotates the turbine at the bottom generating electricity. This Energy tower works well in a dry hot climate.


The Future of Wind Energy

Big rotors or bigger blades usually generate more power from low winds but are more difficult to transport

Engineers are on the way to re model the old existing wind blades which are larger, more bulkier with a new carbon Fiber made wind blades which can be splitted into smaller parts for ease of transport and later can be jointed to form the huge wind blades at the place of production



Blade dynamics fabricate the new blades splitted into multiple parts which can be hauled by standard trucks and can be assembled at a nearby location

Monsanto !!! Bad technology, endless greed and the destruction of humanity

Monsanto Company is a publicly traded American multinational agricultural biotechnology corporation headquartered in Creve Coeur, Missouri. It has it's Branches all over the world including INDIA .

Do you know why Monsanto is a Bio-hazard ?

1. They use genetically modified seeds called terminator technology. When a harvest happens, the seeds produced by the new crops are rendered useless. Although in 1999, Monsanto agreed to not commercialize terminator technology. This means farmers have to repeatedly purchase these seeds.


2. Most crops Monsanto grows are heavily fertilized. In essence your eating pesticides, fertilizer, antibiotics etc.

3. They have uprooted countless agricultural traditions in places like India, Mongolia, Vietnam. For example in India sesame seed oil was once the way people made their money and cooked their food cheaper. Monsanto lobbied the Indian government to use soy bean oil . This destroyed the economic stability of India's subsistence farmers. It is awful for our economy, but also for our health. Immediate heavy intakes of soy can be extremely harmful for the body.

4. Monsanto because of its recent growth by buying out its competitors is imposing a monopoly on the world grain trade, this largest agricultural market in the world. The grain trade feeds cows, pigs, chickens, us, everything we eat comes from grain food. Monsanto by having a monopoly kills smaller businesses, makes us unhealthy, uproots local agriculture etc.



MarchAgainstMonsanto , now trending everywhere .

Hybrid Fruits - Useless of its size

0
In recent days I noticed a thing while I went to market to buy some fruits. The fruits which were present there were almost more bigger in size than the usual ones. A guava was in the size of a Melon. When I was starring at that and amazed "Wow..." "This Much bigger..!!!!" The shopkeeper said " It's a Hybrid Guava from Thailand. Nearer to it was a seedless grape in the size of our original Guava, Reddish Kabul pomegranate and a soft glistening big Bengaluru Cavendish Banana. When I started moving the Shopkeeper said sir " All are of good taste and are more sweeter than the non hybrid ones". "Is sweetness is the only taste that a fruit is having...??"

These bigger and more sweeter fruits are how much safer for body and for agriculture..!!!???

The reason to prescribe the fruits to eat is that they contain the antioxidants, vitamins, minerals and all other stuffs we need in a tasty, juicy combination. But these giant sized hybrid fruits contain how many nutrients. The answer is that they only contain more fibre and fruit juice with a very little amount of nutrients.

Grapes which are grown near my home town has seeds. But even these seeds are highly nutritious. They reduce the risk of Heart attack. They contain a compound called "Risvetrol" which reduces the risk of Heart attack. But without knowing these medicinal properties of seeds we keep throwing them. Here emerged the activities of foreign countries. They started to exchange our seeded grapes with seedless bigger sized grapes to a high rate. Then they extracted the grape seed oil, integrated in a capsule and started to sold them as nutritional tablets. So, we lost our natural heart attack reducer and now buying a synthetic one which does the same at higher price.

Hybrid Vs Original


Already almost most of the fruits now we having are hybrid varieties and more and more hybrid varieties are being imported which makes me to fear that whether it'll affect the usual healthiness of all fruits. Another bad side effect of these hybrids are they need huge amount of fertilizers which potentially spoils the land.

On seeing this some may comment that think practically how can we make food for this huge population with these small amount of land we have, If we keep on having farms were to have houses for us to live. But probably the answer is with them. We can do "sky farming". So, please avoid these overgrown useless fruits and let's change back to our old traditional healthy fruits and lead a healthy life

Biography




Wangari Muta Maathai (born April 1, 1940 in Ihithe village, Tetu division, Nyeri District of Kenya) is a 


Kenyanenvironmental and political activist. She was educated in the United States at Mount St. Scholastica and 


the University of Pittsburgh, as well as the University of Nairobi in Kenya. In the 1970s, Maathai founded the Green 


Belt Movement, an environmental non-governmental organization focused on the planting of trees, environmental 


conservation, and women's rights. In 2004 she became the first African woman to receive the Nobel Peace Prize 


for “her contribution tosustainable development, democracy and peace.” Maathai was an elected member of 


Parliament and served as Assistant Minister for Environment and Natural Resources in the government of 


President Mwai Kibaki between 





Studies in America and Germany


Maathai received a scholarship to study at Mount St. Scholastica College (now Benedictine College), in 


Atchison, Kansas. At Mount St. Scholastica, she majoredin biology, with minors in chemistry and 


German.[11] After receiving her bachelor of science degree in 1964, she was accepted to the University of 


Pittsburgh to study for a master's degree in biology. Her graduate studies at the University of Pittsburgh 


were funded by the Africa-America Institute.[12] During her studies inPittsburgh, Maathai first experienced 


environmental restoration, as environmentalists in the city pushed to rid the city of air pollution.[13] In 


January 1966, Maathai completed her studies at the University of Pittsburgh, earning a Master of Science 


in Biological Sciences,[14] and was appointed to a position as research assistantto a professor of zoology at 







Upon her return to Kenya, Maathai dropped her Christian name, preferring to be known by her birth name, Wangari 
Muta.[16] When she arrived at the University of Nairobi for her new job as a research assistant to the professor of 
zoology, she was informed that her job had been given to someone else. Maathai believes this was because of 
gender and tribal bias.[17] After a job search lasting two months, Professor Reinhold Hofmann, from the University 
of Giessen in Germany, offered her a job as a research assistant in the microanatomy section of the newly 
established Department of Veterinary Anatomy in the School of Veterinary Medicine at University College of 
Nairobi.[18]

In April 1966, she met Mwangi Mathai, another Kenyan who had studied in America, who would later become her 
husband.[19] She also rented a small shop in the city, and established a general store, at which her sisters 
worked. In 1967, at the urging of Professor Hofmann, she traveled to the University of Giessen in Germany in 
pursuit of a doctorate. She studied both at Giessen and the University of Munich.

[edit]Return to Kenya


In the spring of 1969, she returned to Nairobi to continue her studies at the University College of Nairobi as an 
assistant lecturer. In May, she and Mwangi Mathai were married.[20] Later that year, she became pregnant with 
her first child, and her husband campaigned for a seat in Parliament, narrowly losing. During the course of the 
election, Tom Mboya, who had been instrumental in founding the program which sent her overseas, was 
assassinated. This led to President Kenyatta effectually ending multi-party democracy in Kenya. Shortly 
afterward, her first son, Waweru, was born.[21]

In 1971, she became the first Eastern African woman to receive a Ph.D., when she was granted a Doctorate of 
Anatomy[14] from the University College of Nairobi, which became the University of Nairobi the following year. She 
completed her dissertation on the development and differentiation of gonads in bovines.[22] Her daughter, Wanjira, 
was born in December 1971. She continued to teach at the university, becoming a senior lecturer in Anatomy in 
1974, chair of the Department ofVeterinary Anatomy in 1976 and associate professor in 1977. She was the first 
woman appointed to any of these positions in Nairobi.[1] During this time, she campaigned for equal benefits for 
the women working on the staff of the university, going so far as to attempt to turn the academic staff association 
of the university into a union, in order to negotiate for benefits. The courts denied this bid, but many of her 
demands for equal benefits were later met.[23]







Green Belt Movement


Maathai moved into a small home she had purchased years before, and focused on the NCWK while she 
searched for employment. In the course of her work through the NCWK, she was approached by Wilhelm Elsrud, 
executive director of the Norwegian Forestry Society. He wished to partner with the Green Belt Movement and 
offered her the position of coordinator. Employed again, Maathai poured her efforts into the Green Belt Movement. 
Along with the partnership for the Norwegian Forestry Society, the movement had also received "seed money" 
from the United Nations Voluntary Fund for Women. These funds allowed for the expansion of the movement, for 
hiring additional employees to oversee the operations, and for continuing to pay a small stipend to the women who 
planted seedlings throughout the country. It also allowed her to refine the operations of the movement, paying a 
small stipend to the women's husbands and sons who were literate and able to keep accurate records of 
seedlings planted.[35]

In 1985, the UN held the third global women's conference in Nairobi. During the conference, Maathai arranged 
seminars and presentations to describe the work the Green Belt Movement was doing in Kenya. She escorted 
delegates to see nurseries and plant trees. She met Peggy Snyder, the head of UNIFEM, and Helvi Sipilä, the first 
woman appointed a UN assistant secretary general. The conference helped to expand funding for the Green Belt 
Movement and led to the movement's establishing itself outside of Kenya. In 1986, with funding from UNEP, the 
movement expanded throughout Africa and led to the foundation of the Pan-African Green Belt Network. Forty-five 
representatives from fifteen African countries traveled to Kenya over the next three years to learn how to set up 
similar programs in their own countries to combat desertification, deforestation, water crises, and rural hunger. The 
attention the movement received in the media led to Maathai's being honored with numerous awards. The 
government of Kenya, however, demanded that the Green Belt Movement separate from the NCWK, believing the 
latter should focus solely on women's issues, not the environment. Therefore, in 1987, Maathai stepped down as 
chairman of the NCWK and focused her attention on the newly separate nongovernmental organization.[36
