Indian teen discovers cheap way to make saltwater drinkable

February 5, 2017

San Francisco, Feb 5: An Indian-American student has found a cheaper and easier method to turn salt water into drinkable fresh water and his research has caught the attention of major technology firms and universities.

Chaitanya Karamchedu from Portland, Oregon, is turning heads across the country all because of a science experiment that began in his high school classroom.

The Jesuit High School Senior told KPTV that he has big plans of changing the world.

"1 in 8 people do not have access to clean water, it's a crying issue that needs to be addressed," said Karamchedu.

He made up his mind to address the matter himself.

"The best access for water is the sea, so 70 per cent of the planet is covered in water and almost all of that is the ocean, but the problem is that's salt water," said Karamchedu.

Isolating drinkable water from the ocean in a cost effective way is a problem that has stumped scientists for years.

"Scientists looked at desalination, but it's all still inaccessible to places and it would cost too much to implement on a large scale," Karamchedu said.

Karamchedu figured it out, on his own, in a high school lab.

"The real genesis of the idea was realising that sea water is not fully saturated with salt," he was quoted as saying.

By experimenting with a highly absorbent polymer, the teen discovered a cost effective way to remove salt from ocean water and turn it into fresh water.

"It's not bonding with water molecules, it's bonding to the salt," said Karamchedu.

"People have been looking at the problem from one view point, how do we break those bonds between salt and the water? Chai came in and thought about it from a completely different angle," said Jesuit High School Biology Teacher Dr. Lara Shamieh.

"People were concentrated on that 10 per cent of water that's bonded to the salt in the sea and no one looked at the 90 per cent that was free. Chai just looked at it and said if 10 per cent is bonded and 90 per cent is free, then why are we so focused on this 10 per cent, let's ignore it and focus on the 90," Shamieh said.

It is a breakthrough that is estimated to impact millions of lives if ever implemented on a mass scale.

"What this is compared to current techniques, is that it's cheap and accessible to everyone, everyone can use it," said Shamieh.

Scientists across the country are taking note. He won a USD 10,000 award from the US Agency for International Global Development at Intel's International Science Fair and second place at MIT's TechCon Conference where he won more money to continue his research.

"They were very encouraging, they could see things into it that I couldn't, because they've been working their whole lives on this," said Karamchedu.

Back in January, Karamchedu was also named one of 300 Regeneron Science Talent Search Semifinalists. The STS is thought to be one of the most prestigious competitions in the country for high school seniors.

Nestle (Pepsi, Coca Cola, etc.) certainly won't like this! It was Nestle Chairman, Peter Brabeck-Letmathe, who said '?ccess to water is not a public right.'?

I expect this breakthrough discovery will 'somehow' go nowhere, and this smart young man probably needs to start watching his back. Too much profit stands to be lost with this....

Feb 27: With the window to submit comments on India's proposed personal data protection law closing on Tuesday, a period of anxious wait for final version of the Bill started for social media firms.

This comes even as global Internet companies have called on the government for improved transparency related to intermediary Guidelines (Amendment) Rules and allay fears about the prospect of increased surveillance and prompting a fragmentation of the Internet in India that would harm users.

As per the proposed amendments, an intermediary having over 50 lakh users in the country will have to be incorporated in India with a permanent registered office and address.

When required by lawful order, the intermediary shall, within 72 hours of communication, provide such information or assistance as asked for by any government agency or assistance concerning security of the state or cybersecurity.

This means that the government could pull down information provided by platforms such as Wikipedia, potentially hampering its functioning in India.

In the open letter to IT Minister Ravi Shankar Prasad, leading browser and software development platform like Mozilla, Microsoft-owned GitHub and Cloudflare earlier called for improved transparency by allowing the public an opportunity to see a final version of these amendments prior to their enactment.

According to a Business Insider report, Indian users may lose access to Wikipedia if the new intermediary rules for internet and social media companies are approved.

Since the rules would require the website to take down content deemed illegal by the government, it would require Wikipedia to show different content for different countries.

Anusha Alikhan, senior communications director for Wikimedia told Business Insider that the platform is built though languages and not geographies. Therefore, removing content from one country, while it is still visible to other country users may not work for the company’s model.

India is one of Wikipedia’s largest markets. Over 771 million Indian users accessed the site in just November 2019.

The Personal Data Protection Bill, 2019, which was introduced in Lok Sabha in the winter session last year, was referred to a Joint Parliamentary Committee (JPC) of both the Houses.

The government last month decided to seek views and suggestions on the Bill from individuals and associations and bodies concerned and the last date for submitting the comments was on Tuesday.

Prasad, while introducing the Personal Data Protection Bill, 2019, in the Lok Sabha on December 11, announced that the draft Bill empowers the government to ask companies including Facebook, Google and others for anonymised personal data and non-personal data.

There was a buzz when the Bill's latest version was introduced in the Lok Sabha, especially the provision seeking to allow the use of personal and non-personal data of users in some cases, especially when national security is involved.

Several legal experts red-flagged the issue and said the provision will give the government unaccounted access to personal data of users in the country.

In their submission to the JPC, several organisations also flagged that the power to collect non-personal and anonymised data by the government without notice and consent should not form part of the Bill because of issues regarding effective anonymisation and potential abuse.

"Clauses 35 and 36 of the Bill provide unbridled access to personal data to the Central Government by giving it powers to exempt its agencies from the application of the Bill on the basis of various broad worded grounds," SFLC.in, a New Delhi-based not-for-profit legal services organisation, commented.

The Software Alliance, also known as BSA, a trade group which includes tech giants such as Microsoft, IBM and Adobe, among others said that the current version of the privacy bill pose substantial challenges, including the sweeping new powers for the government to acquire non-personal data, restrictions on data transfers, and local storage requirements.

"We urge the Joint Parliamentary Committee, as it considers revisions to the Bill, to eliminate provisions concerning non-personal data from the Personal Data Protection Bill and to remove the data localisation requirements and restrictions on international data flows," said Venkatesh Krishnamoorthy, Country Manager-India, BSA.

The Personal Data Protection (PDP) Bill, 2019 draws its origins from the Justice B.N. Srikrishna Committee on data privacy, which produced a draft of legislation that was made public in 2018 ("the Srikrishna Bill").

The mandatory requirement for storing a mirror copy of all personal data in India as per Section 40 of the Srikrishna Bill has been done away with in the PDP Bill, 2019, meaning that companies like Facebook and Twitter would be able to store data of Indian users abroad if they so wish.

But the bill prohibits processing of sensitive personal data and critical personal data outside India.

What is more, what constitutes critical data has not been clearly defined.

As per the proposals, social media companies will have to modify their application as they are required to have a system in place by which a user can verify themselves.

So legal experts believe that some system to upload identification documents should be there and something like the Twitter blue tick mark should be there to identify verified accounts.

"The 2019 Bill introduces a new category of data fiduciaries called social media intermediaries ('SMIs'). SMIs are a subcategory of significant data fiduciaries ('SDFs') and will be notified by the Central government after due consultation with the DPA, or the Data Protection Authority. Clause 26(4) of the Bill defines SMIs as intermediaries who primarily or solely enable online interaction between two or more users," SFLC.in said.

"On a plain reading of the definition, online platforms like Facebook, Twitter, YouTube, TikTok, ShareChat and WhatsApp are likely to be notified as SMIs under the Bill," it added.

New Delhi, Jul 15: The employees union of state-run telecom operator BSNL will stage protests across the country on Thursday on a host of issues including the cancellation of its 4G tender and non-payment of salaries.

All major unions are organising ‘lunch-hour black-flag' demonstrations throughout the country under the banner of All Unions and Association of BSNL (AUAB), said a statement by AUAB. These demonstrations will be organised, by maintaining social distancing and by taking other precautions, like wearing of masks. The BSNL employees will also wear black-badges the whole day on July 16.

The employees body would demand that BSNL should immediately be allowed to roll out its 4G services and the tender should be issued immediately. Further, they want that in the matter of procuring new equipment and upgradation, there should not be any discrimination between BSNL and other private telecom service providers.

Recently, the Centre cancelled the 4G upgradation tender for BSNL as it had decided to come up with fresh specifications for the upgrade process, in a move to keep Chinese technology companies at bay as the border tussle escalated with the northern neighbour.

The Department of Telecommunications (DoT) would issue a fresh tender for the same, and people in the know said that Chinese companies may not be allowed to participate.

"The agitational programme is being organised to express the deep anguish and resentment of the employees against cancellation of BSNL's 4G tender, cancellation of BSNL's proposal for upgradation of its 49,300 BTSs to 4G, abnormal delay in issuing ‘Add on Order' for 4G equipments, inordinate delay in the implementation of BSNL's Revival Package and against the non-settlement of the burning problems of the employees," said the statement.

The umbrella body of BSNL's employees' unions noted that rolling out of 4G services is the backbone for the revival of this telecom PSU, but the recent cancellation of the tender floated by BSNL for procuring 4G equipment at a cost of Rs 9,300 crore, has brought the company back to square one.

It said that BSNL is already having 49,300 base transceiver stations (BTS), which are 4G compatible and through minor upgradation, all these equipment can be converted into 4G BTSs with an investment of about Rs 1,500 crore.

In addition to this, BSNL could have added another 15,000 BTSs, by placing an Add on Order to the existing mobile tender, it added.

Noting that in October 2019, the PSU could have rolled out pan-India 4G services, AUAB said: "Being the sole owner of the company, the Government of India also cannot shirk its responsibility in this matter."

"Adding insult to injury, the tender floated by BSNL to procure 4G equipment, has been cancelled by the government, based on a complaint from the Telecom Equipments and Services Promotional Council (TEPC)," it said.

AUAB said that BSNL is already lagging four years behind the private operators, in terms of 4G and the cancellation of the tender is going to inordinately delay the company's 4G launch.

Saying that TEPC's contention has been to bar foreign companies from participating in BSNL's tender, AUAB statement pointed out that when private operators are procuring equipment from multinationals, "why BSNL alone should be compelled to procure 4G equipments from domestic vendors, whose 4G technology is not tested or proven so far."

It alleged a conspiracy to destabilise BSNL by disrupting its rolling out of 4G services.

AUAB further said that even after the lapse of nine months, the implementation of the much publicised BSNL's Revival Package is moving at a snail's pace.

"Except the swift retrenchment of 79,000 BSNL employees under VRS, all other assurances given in BSNL's Revival Package have been put in cold storage."

The management should ensure that the salary payment of the employees is made on the last working day of every month. Deductions made from employees' salary, on account of "society dues", should immediately be remitted, it said.

Regarding the monetisation of the company's assets under the revival package, the organisation said that the land asset should not be handed over to corporates, at "throwaway" prices.

"These lands should be sold in a transparent manner and at the prevailing market rates. They should not be sold at book value or at circle rates. The AUAB will strictly monitor these dealings," it said.

Claiming that e-commerce giants like Amazon import as much as 80 per cent of the items sold on their platforms, small manufacturers' body has said that their business models do not benefit local industry and are creating jobs of delivery boys only.

"Neither manufacturers nor traders are getting any benefit from the business models of Amazon and Flipkart because they largely import their products from China and Korea and sell here. Nearly 80 per cent of their products are imported," said Anil Bhardwaj, Secretary General, Federation of Indian Micro and Small & Medium Enterprises (FISME).

Bhardwaj said that the global e-commerce players generally source and sell products through their own preferred suppliers and as a result a large number of local manufacturers and traders get crowded out.

He listed out deep discounting and buying products from preferred companies as unfair practices.

"Even if they buy products from local suppliers the commission charged is very high," Bhardwaj said adding that the issues related to unfair practices have been raised with Commerce Ministry on multiple occasions.

FISME maintains that the technology-driven retail is way forward and one cannot be oblivious of the benefits it brings to consumers but at the same time the local industry can also not be ignored given its role in job creation.

"If both traders and local manufacturers are crowded out then how would the local industry survive and employment be generated?" asked Bhardwaj.

As Amazon Founder and CEO Jeff Bezos is currently on his three-day visit to India, the local traders are up in arms against the "unfair" trade practices of the tech giant. Delhi-based Confederation of All India Traders (CAIT) has launched a countrywide protest against the company and has organised protests across 300 cities.

In a setback to Amazon and Walmart-backed Flipkart, the fair market watchdog Competition Commission of India (CCI) has ordered probe into the business operations of both the companies on multiple counts including deep-discounts and exclusive tie-up with preferred sellers.

"For the first time some concrete step has been taken against Amazon and Flipkart who are continuously violating the FDI policy in indulging in a vicious racket of controlling and monopolising not only the e-commerce but even the retail trade as well," CAIT National Secretary General Praveen Khandelwal said after the CCI order.
