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.

Jun 4: Mahatma Gandhi’s statue outside the Indian Embassy in Washington DC was vandalised with graffiti and spray painting by unknown persons allegedly involved in the ongoing protests in the US against the custodial killing of African-American George Floyd.

This has prompted the mission officials to register a complaint with the local law enforcement agencies.

The incident is reported to have taken place on the intervening night of June 2 and 3 in Washington DC.

The Indian embassy has informed the State Department and registered a complaint with local law enforcement agencies, which are now conducting an investigation into the incident.

On Wednesday, a team of officials from Metropolitan Police in consultation with the Diplomatic Security Service and National Park Police visited the site and are conducting inquiries.

Efforts are on to clean up the site at the earliest.

Vandalism of the statue of the apostle of peace comes during the week of nationwide protests against the custodial killing of African-American George Floyd in Minneapolis on May 25.

Several of these protests have turned violent which many times has resulted in damage of some of the most prestigious and sacred American monuments.

In Washington DC, protestors this week burnt a historic church and damaged some of the prime properties and historic places like the national monument and Lincoln Memorial.

One of the few statues of a foreign leader on a federal land in Washington DC, the statue of Mahatma Gandhi was dedicated by the then Prime Minister Atal Bihari Vajpayee, in the presence of the then US president Bill Clinton on September 16, 2000, during his state visit to the US.

In October 1998, the US Congress had authorised the government of India to establish and maintain a memorial “to honour Mahatma Gandhi on Federal land in the District of Columbia."

According to the Indian Embassy website, the sculpture of Mahatma Gandhi is cast in bronze as a statue to a height of 8 feet 8 inches. It shows Gandhi in stride, as a leader and man of action evoking memories of his 1930 protest march against salt-tax, and the many padyatras (long marches) he undertook throughout the length and breadth of the Indian sub-continent.

The statue, the design of which was created by Gautam Pal, is a gift from the Indian Council for Cultural Relations (ICCR). The pedestal for the statue of Mahatma Gandhi is a block of new Imperial Red also known as Ruby Red a block originally weighing 25 tonnes reduced to a size of 9'x7'x3'4". It now weighs 16 tonnes.

Beijing, Mar 24:  China reported 78 new confirmed cases, including 74 imported infections, while the death toll from the novel coronavirus increased to 3,277 after seven more fatalities were confirmed from the COVID-19, health officials said on Tuesday.

The overall confirmed cases on the Chinese mainland have reached 81,171 by the end of Monday. This included 3,277 people who died of the disease, 4,735 patients who were still being treated and 73,159 patients discharged after recovery, the National Health Commission (NHC) said on Tuesday.

The NHC said, 78 new confirmed COVID-19 cases were reported on the Chinese mainland on Monday, of which 74 were imported from abroad taking the number of overseas cases to 427.

Also on Monday, seven deaths and 35 new suspected cases were reported on the mainland with all the deaths in Hubei Province.

The total COVID-19 cases in Beijing climbed to 522 with eight deaths prompting local governments of Beijing as well as Shanghai to announce that all overseas arrivals will be subjected to nucleic acid tests to ensure proper detection.

Of the 74 newly imported cases, 31 were reported in Beijing, 14 in Guangdong, nine in Shanghai, five in Fujian, four in Tianjin, three in Jiangsu, two in Zhejiang and Sichuan respectively, and one in Shanxi, Liaoning, Shandong and Chongqing respectively, the NHC said.

Beijing is already diverting all international flights to different cities where the passengers will be quarantined for 14 days before arriving in the city.

The NHC said 132 people were still suspected of being infected with the virus.

Coronavirus epicentre Wuhan has reported one confirmed case after a gap of five days prompting officials to begin to ease restrictions.

Wuhan also reported seven new deaths, bringing the total number of deaths in the city and Hubei province for which Wuhan is the capital to 3,160.

The province also saw 444 patients discharged from hospital after recovery on Monday. Among the 4,200 patients being treated in hospital, 1,203 were still in severe condition and another 336 in critical condition, the local health commission said.

By the end of Monday, 356 confirmed cases, including four deaths have been reported in Hong Kong, which has restricted the entry of foreigners into the city. Also a total of 25 confirmed cases were reported in Macao and 195 in Taiwan including two deaths, state-run Xinhua news agency reporrted.

After days of decline in coronavirus cases, China on Monday said that COVID-19 has effectively been "stemmed" in the country and it started easing severe restrictions imposed on Wuhan's 11 million people who were under lockdown since January 23.

The authorities began relaxing restrictions in Wuhan as it reported no new case for the fifth consecutive day on Monday.

Significantly, the Central Leading Group (CLP), headed by Premier Li Keqiang which is coordinating efforts to contain the virus since January 23, said the virus has been curtailed in the country as well as in Wuhan.

"The meeting noted that the spread of the virus nationwide, particularly in the epicentre of Wuhan, has been effectively stemmed," an official statement said on Monday.

The meeting, however, warned that the risks for sporadic infections and localised outbreaks have not gone away. With the pandemic rampaging across the world, the situation remains complex and challenging.

"Wuhan city and Hubei province should stay focused on medical treatment and community-level containment as the two key priorities. They should continue to treat the severe cases, promptly admit new cases, and advance epidemiological investigations," the meeting said.

In Wuhan, officials said people are allowed to go back to work while restrictions on the public transport are gradually being eased.

The Hubei province and its capital Wuhan with over 56 million people were under lockdown since January 23. The vicious virus broke out in city, reportedly at a live animal market in December last year and became virulent inflicting thousands of people in the city and province catching the government off guard.

As the country saw a surge in imported infections, the Chinese government announced that all international flights scheduled to arrive in Beijing will be redirected to airports in 12 other Chinese cities from Monday.

International passengers flying to Beijing will instead land at airports in 12 cities including Shanghai, Tianjin, Nanjing and Shenyang as their first points of entry, the Civil Aviation Administration of China (CAAC) said in a statement.

On Monday, China said international travellers should "think twice" about choosing Beijing for flight transfer in view of the restrictions.

Starting from Monday, all international flights scheduled to arrive in Beijing will be redirected to airports in 12 other Chinese cities, Liu Haitao, an official with China's National Immigration Administration said.

Passengers would go through entry procedures and quarantine measures at the designated cities' airports before they continue their flights to Beijing, Liu said, urging travellers to reserve enough time for their next flights to make sure that they do not miss their outbound flights.

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.
