African teens come up with 'pee-powered' generator

London, November 12: In a breakthrough, four teenage schoolgirls in Nigeria have invented a ‘pee-powered' generator that converts one litre of urine into six hours of electricity.


Fourteen-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola presented their invention at the Maker Faire Africa entrepreneurs event, in Lagos, using a resource that is free, unlimited and easily obtainable.

According to the Maker Faire blog, urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and hydrogen.

The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder, the Daily Mail reported.

The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.

This purified hydrogen gas is pushed into the generator, and one litre of urine provides six hours of electricity.

Maker Faire blog described the generator as “possibly one of the more unexpected products” at the event.

While the system does have one-way valves for safety, more robust measures may be needed before it can be sold widely.

The report noted: “Let's be honest that this is something of an explosive device”.


Nigeria's economy is on the rise, however, more than half of the country's 162 million citizens have no access to electricity, and even those who do can't guarantee having power every day, the report said.

Langkawi, Jan 20: Malaysia will not take retaliatory trade action against India over its boycott of palm oil purchases amid a political row between the two countries, Prime Minister Mahathir Mohamad said on Monday.

India, the world’s largest edible oil buyer, this month effectively halted imports from its largest supplier and the world’s second-biggest producer in response to comments from Mahathir attacking India’s domestic policies.

“We are too small to take retaliatory action,” Mahathir told reporters in Langkawi, a resort island off the western coast of Malaysia. “We have to find ways and means to overcome that,” he added.

The 94-year-old premier of Muslim-majority Malaysia has criticised New Delhi’s new religion-based citizenship law and also accused India of invading the disputed region of Kashmir.

Mahathir again criticised India’s citizenship law on Monday, saying he believed it was “grossly unfair”.

India has been Malaysia’s largest palm oil market for the past five years, presenting the Southeast Asian country with a major challenge in finding new buyers for its palm oil.

Benchmark Malaysian palm futures fell nearly 10% last week, their biggest weekly decline in more than 11 years.

New Delhi is also unhappy with Malaysia’s refusal to revoke permanent resident status for controversial Indian Islamic preacher Zakir Naik, who has lived in Malaysia for about three years and faces charges of money laundering and hate speech in India.

Mahathir said even if the Indian government guarantees a fair trial, Naik faces the real threat of vigilante action and that Malaysia will only relocate the preacher if it can find a third country where he would be safe.

“If we can find a place for him, we will send him out.”

Washington, Feb 19: Sri Srinivasan, a prominent Indian-American judge, has created history by becoming the first person of South Asian descent to lead a powerful federal circuit court considered next only to the US Supreme Court.

Srinivasan, 52, became the Chief Judge of the United States Court of Appeals for the DC Circuit.

An Obama appointee who has already been considered for a Supreme Court seat twice, donned the mantle of the chief judge of the DC federal court circuit on February 12.

Srinivasan succeeded Judge Merrick Garland, who has been a member of the DC Circuit since 1997 and Chief Judge since 2013. He will remain on the bench, a press release said.

Notably, Garland's nomination to the Supreme Court by the then president Barack Obama was blocked by Senate Republicans in 2016.

Srinivasan, was appointed to the US Court of Appeals for the District of Columbia Circuit in May 2013.

He was the first ever Indian-American to be appointed to the second most powerful court of the US.

Neomi Rao, nominated by President Donald Trump, is the second Indian American on this powerful judiciary bench.

History being made on the DC Court of Appeals. Congratulations, Judge Srinivasan! Senator Mark Warner said.

Congratulations to Judge Sri Srinivasan on becoming the Chief Judge of the U.S. Court of Appeals for the D.C. Circuit! A milestone for the Indian-American/Kansan community (and yet another piece of evidence my family can use that I'm underachieving), US Federal Communications Commission Chair Ajit Pai said.

According to The Washington Post, Srinivasan spoke recently about his path to the bench at an event celebrating women in the law, a field where men still dominate leadership positions.

"Everybody doubts their belonging and worthiness in some measure. I definitely did and still do. This is just going to be a part of the thing when you're looking out in the world in which everyone isn't like you. It's natural to doubt whether you belong and whether you're worthy, he said, "but you do belong and you are worthy.

Born in Chandigarh, and raised in Lawrence, Kansas, he received a B.A. from Stanford University, a J.D. from Stanford Law School, and an M.B.A. from the Stanford Graduate School of Business.

Following graduation, he served as a law clerk to Judge J. Harvie Wilkinson III of the US Court of Appeals for the Fourth Circuit, as a Bristow Fellow in the Office of the US Solicitor General, and as a law clerk to US Supreme Court Justice Sandra Day O'Connor.

From 2011 until his appointment to the US Court of Appeals, Judge Srinivasan served as the Principal Deputy Solicitor General of the United States.

He has argued 25 cases before the US Supreme Court. He has also taught appellate advocacy at Harvard Law School as well as a seminar on civil rights statutes and the Supreme Court at Georgetown University Law Center.

Houston, Jun 10: George Floyd was fondly remembered Tuesday as “Big Floyd” — a father and brother, athlete and neighborhood mentor, and now a catalyst for change — at a funeral for the black man whose death has sparked a global reckoning over police brutality and racial prejudice.

More than 500 mourners wearing masks against the coronavirus packed a Houston church a little more than two weeks after Floyd was pinned to the pavement by a white Minneapolis police officer who put a knee on his neck for what prosecutors said was 8 minutes and 46 seconds.

Cellphone video of the encounter, including Floyd’s pleas of “I can’t breathe,” ignited protests and scattered violence across the U.S. and around the world, turning the 46-year-old Floyd — a man who in life was little known beyond the public housing project where he was raised in Houston’s Third Ward — into a worldwide symbol of injustice.

“Third Ward, Cuney Homes, that’s where he was born at,” Floyd’s brother, Rodney, told mourners at the Fountain of Praise church. “But everybody is going to remember him around the world. He is going to change the world.”

The funeral capped six days of mourning for Floyd in three cities: Raeford, North Carolina, near where he was born; Houston, where he grew up; and Minneapolis, where he died. The memorials have drawn the families of other black victims whose names have become familiar in the debate over race and justice — among them, Eric Garner, Michael Brown, Ahmaud Arbery and Trayvon Martin.

After the service, Floyd’s golden casket was taken by hearse to the cemetery in the Houston suburb of Pearland to be entombed next to his mother, for whom he cried out as he lay dying. A mile from the graveyard, the casket was transferred to a glass-sided carriage drawn by a pair of white horses. A brass band played as his casket was taken inside the mausoleum.

Hundreds of people, some chanting, “Say his name, George Floyd,” gathered along the procession route and outside the cemetery entrance in the mid-90s heat.

“I don’t want to see any black man, any man, but most definitely not a black man sitting on the ground in the hands of bad police,” said Marcus Brooks, 47, who set up a tent with other graduates of Jack Yates High School, Floyd’s alma mater.

In the past two weeks, amid the furor over Floyd’s death, sweeping and previously unthinkable things have taken place: Confederate statues have been toppled, and many cities are debating overhauling, dismantling or cutting funding for police departments. Authorities in some places have barred police from using chokeholds or are otherwise rethinking policies on the use of force.

Dozens of Floyd’s family members, most dressed in white, took part in the four-hour service. Grammy-winning singer Ne-Yo was among those who sang.

The mourners included actors Jamie Foxx and Channing Tatum, J.J. Watt of the NFL’s Houston Texans, rapper Trae tha Truth, Rep. Sheila Jackson Lee, Houston Police Chief Art Acevedo and Houston Mayor Sylvester Turner, who brought the crowd to its feet when he announced he will sign an executive order banning chokeholds in the city.

“I know you have a lot of questions that no child should have to ask, questions that too many black children have had to ask for generations: Why? Why is Daddy gone?” former Vice President Joe Biden, the Democratic presidential candidate, said, addressing Floyd’s 6-year-old daughter in a video eulogy played at the service. “Now is the time for racial justice. That’s the answer we must give to our children when they ask why.”

Biden made no mention of his opponent in November. But other speakers took swipes at President Donald Trump, who has ignored demands to address racial bias and has called on authorities to crack down hard on lawlessness.

“The president talks about bringing in the military, but he did not say one word about 8 minutes and 46 seconds of police murder of George Floyd,” said the Rev. Al Sharpton, the civil rights activist. “He challenged China on human rights. But what about the human right of George Floyd?”

Most of the pews were full, with relatively little space between people.

“So much for social distancing today,” the Rev. Remus Wright told mourners, gently but firmly instructing those attending to wear face masks.

Texas has no limit on how many people can gather in places of worship during the pandemic, though Republican Gov. Greg Abbott has encouraged churches to follow federal health guidelines.

Although the church service was private, at least 50 people gathered outside to pay their respects.

“There’s a real big change going on, and everybody, especially black, right now should be a part of that,” said Kersey Biagase, who traveled more than three hours from Port Barre, Louisiana, with his girlfriend, Brandy Pickney. They wore T-shirts printed with Floyd’s name and “I Can’t Breathe.”

Floyd served nearly five years in prison for robbery with a deadly weapon before becoming a mentor and a church outreach volunteer in Houston. He moved to Minnesota several years ago through a program that tried to change men’s lives by helping them find work in new settings.

At the time of his death, Floyd was out of work as a bouncer at a Minneapolis club that had closed because of the coronavirus outbreak. He was seized by police after being accused of passing a counterfeit $20 bill at a convenience store.

Four Minneapolis officers were arrested in his death: Derek Chauvin, 44, was charged with second-degree murder. J. Alexander Kueng, Thomas Lane and Tou Thao were charged with aiding and abetting. All four could get up to 40 years in prison.

Some of the mostly peaceful demonstrations that erupted after Floyd’s death were marked by bursts of arson, assaults, vandalism and smash-and-grab raids on businesses, with more than 10,000 people arrested. But protests in recent days have been overwhelmingly peaceful.
