Mangalore Boy Uses Kites to Harness Wind Power & Generate Electricity…!!!

A young boy in Mangalore bagged the Gandhian Young Technological Innovation Award for his innovative project that harnessed the power of wind, through kites.

22-year-old Royston Vijay Castellino, who studied at the Srinivas Institute of Technology, Mangalore, looked into the impact of wind power systems, and concluded that they have limitations to produce electricity. However, his innovative model, which uses a kite to harness wind from high altitudes, wipes out those inefficiencies.

Calling it the “Winds of Change”, he has also applied for a patent.

In 2015, he had completed a project on this as part of his BE electronics and electrical engineering course in his final year. The aim of his project, according to Castellino, was to make wind power generation low cost, increase efficiency, and make it useful in generating electricity in rural areas.

When he experimented on kites, he discovered that the power is at its peak from a kite when it is rotated to make an infinity symbol in the sky. “I also observed that a four-line kite gives more power than a dual-line kite. So, I started to build a strong base with a four-line kite control system,” he said.

To work on the model, he said that he first ordered a four-line power kite from China. Then, he found bicycle parts, crank wheels and sprockets to use as materials. He modified a ceiling fan with permanent magnets, and then wound the rims of the bicycle wheel with threads. He used a wireless transmitter and receiver circuit to control the kite through a motor, and a chain drive to increase the speed. “The output can be improved by increasing the area of the kite,” he explained, “And the project can be made fully automatic by installing sensors on the kite which determine the position of the kite and send data to the base station.”

Since wind energy can be intermittent, he said that two similar kites can produce continuous power. “By installing two kites, energy can be transferred to the utility grid directly. This project can be made highly portable by using a vehicle as a base station which consists of a generator and control system.”

Last year, he was awarded the Project of the Year Award by Karnataka State Council for Science and Technology, at a competition organised by Indian Institute of Science in Bengaluru.

What Birds teach us….Learn from Them…Keep Singing….!!!

Life is tough, and if you thought that the lives of animals were any easier, you’re wrong. Nature itself brings a lot of challenges we all have to face – whether you’re human or not. But essentially, life is created in such a way so as to enable us to withstand the challenges and overcome the hardships they bring. If there’s one creature in nature that’s a perfect example of this -it’s undoubtedly the bird, with all its patience and perseverance. Here’s what this beautiful animal can teach us about life…

Message for the Day…” Have a sense of Gratitude …”

Sathya Sai Baba

All of you should earnestly investigate the presence of Divinity in human life. Awareness of your duty is equal to the awareness of Divinity in daily living. In the modern world, nobody has a sense of gratitude. Some of you fail to show gratitude even to doctors who heal you when you were sick. You argue that you need not be grateful to the Doctor because it is their duty to cure a suffering patient. But remember, as a patient, you too have a duty. Flagrant violation of duty leads you nowhere. It is your duty to show gratitude to the mother who nourished you in the womb and fostered your well being. Strange, but many even question why they should be grateful to the mother, who, in their opinion, is duty bound to take care of her children. Please internalise that it is your primary duty to take care of your mother who gave birth to you and raised you.

Message for the Day…” One should earnestly investigate the presence of Divinity in human life …”

When you become conscious of the light, acquire wisdom and realise the meaning of existence, you will be transported from agony to ecstasy. Light here does not signify the light of the Sun, the Moon or the lamp, but that of the heart. Wisdom does not refer to scientific wisdom, but enlightenment brought about by the transformation of the heart. What about existence? Awareness of your own true reality is the proper meaning of existence. The awareness of your reality lies in the realisation that you are not the body, the mind or the senses. True realisation lies in understanding the fact that you are based on a transcendental principle that goes beyond the boundaries of matter. One should earnestly investigate the presence of Divinity in human life. Awareness of one’s own duty is tantamount to the awareness of Divinity in human life.

How a Zero Rupee Note Can Help You Fight Corruption and Bribery in India….!!!

India has a unique tool meant for fighting corruption in a non-violent manner and to shame corrupt officials asking for bribes – it is called the Zero Rupee Note. Launched by 5th Pillar, an NGO working against corruption in the country, the Zero Rupee Notes are for people to use whenever someone asks for bribes.

It empowers common citizens with the knowledge that they are not alone in this fight, and also gives them a very strong weapon to say no to corrupt practices.

The Zero Rupee Note was conceptualised by Vijay Anand, the founder of 5th pillar, in 2007. The NGO’s volunteers started distributing the notes in market places, railway stations, bus stops, shopping malls, etc. It resembles a fifty rupee note but is larger than a thousand rupee note. The organization’s contact information is printed on it along with an anti-bribery message saying – “If anyone demands a bribe, give this note and report the case”.

It also carries a strong pledge for citizens to take – “I promise to neither accept nor give bribe.”

More than 3 million notes have been distributed across the country so far and are being used well. One of the impact stories described by 5th Pillar on their website goes as follows –

“Mr. Ashok Jain went to retrieve his towed car from Chennai’s C1 police station. The police asked him to pay Rs. 800 (Rs. 150 fine + Rs. 650 bribe). Mr. Jain said he would pay in exchange for a receipt, which the police wouldn’t give. After much talking and pleading, Mr Ashok called his friend Vinod Jain, who came to the station and handed a Zero Rupee Note to the police. The police saw the note, withdrew their demand for the bribe, accepted the Rs. 150, and gave the receipt without question.”

“Many factors contribute to the success of the Zero Rupee Notes in fighting corruption in India. First, bribery is a crime in India punishable with suspension and jail time. Corrupt officials seldom encounter resistance by ordinary people that they become scared when people have the courage to show their Zero Rupee Notes, effectively making a strong statement condemning bribery,” Vijay told Zee News.

Anand Prakash saved a billion of Facebook users……

People think I do this for money, but I don’t. I do it because I value data privacy, says Anand Prakash.
Throwing a backpack casually over a table in a coffee house, Anand Prakash is completely in sync with his new-found popularity. “Ask me your questions,” says the 22-year-old who agrees that he is getting used to interviews.
Bengaluru-based Prakash’s name attracted attention after his blog post started seeing traction. Prakash wrote about how he had found a “simple vulnerability” on Facebook, for which the networking portal gave him a bounty of $15,000.
But this wasn’t the first time that Prakash, a security engineer at Flipkart, was rewarded for finding a bug. He has spotted 90 bugs for Facebook alone and about 30 for Twitter. Those who have given him bounties in the past for reporting security vulnerabilities include global web giants such as Google, Red Hat, Dropbox, Adobe, eBay and PayPal.
What was alarming about this particular bug was that it instantly allowed Prakash access to accounts of the billion users Facebook has — credit and debit card details, personal photos and more. Prakash’s friend and colleague Ankur Bhargava, also a security analyst, explains that Prakash got the bounty not for the bug itself, but because of the severe consequences that it could have.
“If this bug was sold in the grey market where hackers could have exploited it, Anand could have easily made millions of dollars,” says Bhargava. “He could have earned easy money, but he chose not to and waited till Facebook fixed the bug before making the bug public.” Similarly, when Prakash found a bug on Zomato and had access to all of its user accounts, he reported it straight to Zomato. There was no bounty for this one.
“People think I do this for money, but I don’t. I do it because I value data privacy,” says Prakash. His parents, back home in Rajasthan,

do not understand his work, but just know he has grown to spend a lot of time with computers now.

Once an intern with the cyber crime cell of the Gurgaon police, Prakash recalls seeing young girls walking into the police station to report harassment. “It was so disturbing to see them in tears. The main issue was of their private data being leaked. It was all happening in real time and I realised the importance of data security measures,” he says.
Prakash’s interest in website security dates back to pre-Facebook days in India, the days when Orkut was all the rage. “A friend bet that I couldn’t hack into his account; I didn’t even know how these things worked, so I just started looking things up,” he says. He went on to win the bet.
“Anand has found a lot of cool bugs on different websites; it’s his perspective and attitude towards things that makes him stand out against the rest. Hacking is a technique, but how you break things down and the way you think about it also matters,” says Bhargava.
Prakash doesn’t check in on Facebook, no matter where he goes, has no (private) messages online, or even a display picture on WhatsApp — Prakash is solely on social media to find and fix security vulnerabilities. “I never store my card details online, either — it’s just not safe,” he says.
In the days to come, Prakash has the tough task of sifting through his social media accounts. The morning after he first blogged about finding this particular bug, he had 500 new followers on Twitter and had hundreds of messages waiting for him on Facebook. Most of these were requests from those who wanted Prakash to hack into their girlfriends’ accounts.
Happy to be at Flipkart “because it’s a really cool and chilled-out place to work,” Prakash is also excited about what the future holds as he dreams of going the entrepreneurial way soon.

Message for the Day…” The day you realise the purpose of life, You undergo a total transformation …”

t is the foremost duty of students to transform every activity of life into one of strength and beauty. But unfortunately, the education system of today fails to nourish the qualities of wholesomeness, unity and love, which are the hallmarks of true education. Students must realise that their lifespan is fast melting away like ice, whether they care to improve or not. Students of today are blind to the goal of life; many do not even feel the pain of not knowing the purpose of life. Only one in a million strives to realise the essence of life. This striving is the steppingstone for the realisation of the purpose of life. Many people feel that the acquisition of food, clothing, shelter, wealth, conveniences, and comforts constitute the very purpose of life. Life remains a tragedy as long as people toil under this kind of delusion. The day you realise the purpose of life, you undergo a total transformation, from agony (vedhana) to freedom from pain(nirvedhana)

Dharavi…….. Redesigned !!!

A potter in Dharavi

Museum is not exactly the word that comes to mind when you step into this little square of open land near the Kumbharwada (Potters’s Colony) signal in Dharavi, Mumbai’s much coveted real estate that sprawls over nearly 600 acres, houses families cheek-by-jowl in tiny one-room homes that lean into each other, accessed by everything from roads to very, very, very narrow lanes bisected by vein-like gutters though which flows sludge-like, smelly dark liquid… the amalgamated refuse of the thousands of people who inhabit this patch of land once infamously known as Asia’s largest slum and then made famous by Danny Boyle’s Slumdog Millionaire.

In front of you is a bright white 8 feet by 4 feet cart, a little like the one you see pushed vegetable vendors all over Mumbai. Only, it is larger, made of metal, brightly lit, with brick-coloured panels that open welcomingly to 24 feet, can bear the weight of almost 1,000 kgs and looks quite out-of-place.

It is this dichotomy that, hope Amsterdam-based artists Jorge Mañes Rubio and Amanda Pinatih, will draw the people of Mumbai in. And inspire the people of Dharavi, many of whom stand around stoically, wondering what was happening.

“Museum,” say best friends Akansha, Ayesha and Riya, bright eyed 10-year-old Class 6 students who stay nearby. They explain that museums normally “carry things about the past” but this one is different. This one, they proudly say, showcases “Dharavi ki kala (the creativity of Dharavi).”

That, says 31-year-old Rubio, is the museum’s very purpose. Both Rubio and Pinaith admire the way the denizens of Dharavi have found ways to earn a living. “You can bring a purse here,” says Rubio, “or a jacket, or hand over a design for shoes, and they will replicate it for you.”

What they hope this museum will do is help the citizens of Dharavi tap into their creativity.

Looking around him, says Rubio, is motivation enough, as he recalls his first visit to Dharavi four years ago. Crammed into tiny spaces, where you would believe a nuclear family could live, hundreds of cottage industries flourish, making everything from earthen lamps to designer rip-off to food products to even soaps.

With a dash of creativity, they hope these entrepreneurs — from those who maintain their generations old family trade to those who are using the latest technology to set up new business — will be able to expand the scope of what they do, reach wider audiences and make more money.

To break the communication barrier, and earn the trust of the residents of Dharavi, they turned to URBZ, an experimental urban research and action collective. It was here that they met Shyam Kanle, who lives in Dharavi and has been working to improve the condition of its residents. Kanle, who belongs to a family of basket weavers and broom makers, stepped in as facilitator.

On February 18, the museum launched in Kumbharwada with exhibits made by the potters, given a design and colour spin by Rubio and his team, whose effort is being supported by the Creative Industries Fund NL and The Art of Impact.

The museum, says Rubio, who has bundled up his hair in a bun to beat the heat, is interactive and will include workshops and, like a few days ago, even a cricket match. Each of the items in the museum, emphasises Rubio, is made by local talent.

Yes, those are bats and you are supposed to play with them. To add some more change, Design Museum Dharavi offers modified gloves and stumps too.

Twenty-seven hand-crafted bats, made from recycled wood in different shapes, sizes and designs, are tested by four teams from across Dharavi. Each has a brightly coloured grip. The leather gloves, too, are handcrafted and features different styles. Each team had its own uniquely designed tee shirt.

Now that the bats and gloves had been designed, it was time for some intense concentration and a game of cricket. Even the pink stumps did not distract the players.

While some of the bats worked, others shattered in a matter of minutes.

Pots and brooms at the Design Museum Dharavi.

The launch exhibit celebrated matkas (pots used to store water and keep it cool), brooms and tea cups.

Pots, that were generally stacked one top the other to save space, were given an exotic design spin.

Tea cups at the Design Museum Dharavi.

Why should a cup look like a cup? “Why indeed?” asks Rubio as he spotlights the exotic shapes of the cups, with handles shaped like the human ear, triangles or even rectangles, all inspired, he solemnly assures, from the varied ways in which he has watched the Dharavi residents pick up a hot cup of chai.

Resting on a pristine white block placed on a brightly coloured reed mat are still more exotic tea cups even more exotic handles. A couple look like diyas and we wonder how useful they would be while sipping a hot beverage.

Experiment is everything, seems to be the motto. So there are more cup; some with saucers. “Sharing a cup of tea or sipping it from a saucer,” says Rubio is something he has noticed as he watched endless cups of chai make their way down thirsty throats.

Design samples at the Design Museum Dharavi

These exhibits grabbed a lot of attention. Not only were they bright and colourful, nobody seemed to know what they actually were.

“Diaries?” somebody ventured. Touching them put paid to that idea.

“Tiles?”

“Door-stoppers?”

“Coasters?”

“Design samples,” says Rubio, “that the potters can offer as options to their clients.”
