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.

Paris, Aug 5: French President Emmanuel Macron on Tuesday said France will deploy a civil security detachment and several tonnes of medical equipment to Lebanon, whose capital was hit by an explosion that left over 70 people dead and thousands injured.

"Emergency doctors will also reach Beirut as soon as possible to strengthen hospitals. France is already engaged," the French President said in a tweet.

US Secretary of State Mike Pompeo, also extended his deepest condolences to all those affected by the "massive explosion at the port of Beirut."

"We are closely monitoring and stand ready to assist the people of Lebanon as they recover from this tragedy. Our team in Beirut has reported to me the extensive damage to a city and a people that I hold dear, an additional challenge in a time of already deep crisis. 

We understand that the Government of Lebanon continues to investigate its cause and look forward to the outcome of those efforts," he said in a statement.

UK Prime Minister Boris Johnson said his country is ready to provide support in any way it can.

"The pictures and videos from Beirut tonight are shocking. All of my thoughts and prayers are with those caught up in this terrible incident. The UK is ready to provide support in any way we can, including to those British nationals affected," Johnson said.

Israeli people share the pain of their Lebanese neighbours after a devastating blast in the port of Beirut and reach out to offer their aid, Israeli President Reuven Rivlin said on Tuesday.

"We share the pain of the Lebanese people and sincerely reach out to offer our aid at this difficult time," Rivlin said on Twitter.

Kuala Lumpur, Jul 28: Malaysia's ex-leader Najib Razak was found guilty Tuesday in his first trial over the multi-billion-dollar 1MDB scandal, two years after the fraud contributed to the downfall of his long-ruling government.

The former prime minister could now face decades in jail after being convicted on all charges in the case related to the looting of sovereign wealth fund 1Malaysia Development Berhad.

Billions of dollars were stolen from the investment vehicle and spent on everything from high-end real estate to pricey art, while investment bank Goldman Sachs also became embroiled in the scandal.

Anger at the looting played a large part in the shock loss of Najib's long-ruling coalition in elections in 2018, and he was arrested and hit with dozens of charges following his defeat.

The verdict was a test of Malaysia's rule of law. It comes about five months after Najib's scandal-plagued party returned to power as part of a coalition, development observers had feared could affect the outcome of the case.

About 16 months after it began, the Kuala Lumpur High Court delivered the verdict in Najib's first trial, which centred on the transfer of 42 million ringgit ($9.9 million) from a former 1MDB unit, SRC International, into his accounts.

Najib had vehemently denied wrongdoing.

But Judge Mohamad Nazlan Mohamad Ghazali took apart all the arguments put forward by his defence, and found him guilty on the seven charges he faced.

"In conclusion, after considering all the evidence in this trial, I find the prosecution has successfully proven the case," the judge told the court.

The charges were one of abuse of power, three of criminal breach of trust and three of money-laundering.

The counts of abuse of power and criminal breach of trust are punishable by up to 20 years in jail each, while the money-laundering charges are punishable by up to 15 years each.

Sentencing was not handed down straight away. The 67-year-old will likely appeal and he may not be sent to jail immediately. If his conviction is upheld, he will also be barred from political office for several years.

Najib had insisted he was ignorant of the transactions.

The defence team portrayed Najib as a victim and instead sought to paint financier Low Taek Jho, a key figure in the scandal who has been charged in the US and Malaysia, as the mastermind.

Low, whose whereabouts are unknown, maintains his innocence.

Prosecutors insisted Najib was in control of the 1MDB unit, SRC International.

The return of Najib's party to power as part of a coalition in March followed the collapse of Mahathir Mohamad's reformist administration.

Since then, 1MDB-linked charges were unexpectedly dropped against the ex-leader's stepson Riza Aziz, a producer of Hollywood movie "The Wolf of Wall Street", in exchange for him agreeing to return assets to Malaysia.

Prosecutors also dropped dozens of charges against Najib ally Musa Aman, the former leader of Sabah state.

The amounts involved in Najib's first case are small compared to those in his second and most significant trial, which centres on allegations he illicitly obtained more than $500 million.

Malaysia had charged Goldman Sachs and some current and former staff, claiming large amounts were stolen when the bank arranged bond issues for 1MDB.

But the two sides agreed to a $3.9 billion settlement last week in exchange for charges being dropped.

Minneapolis, May 31: The full Minnesota National Guard was activated for the first time since World War Two after four nights of civil unrest that has spread to other U.S. cities following the death of George Floyd, a black man shown on video gasping for breath as a white Minneapolis policeman knelt on his neck.

Minnesota Governor Tim Walz said the deployment was necessary because outside agitators were using protests over Monday’s death of George Floyd to sow chaos and that he expected Saturday night’s demonstrations to be the fiercest so far.

From Minneapolis to several other major cities including New York, Atlanta and Washington, protesters clashed with police late on Friday in a rising tide of anger over the treatment of minorities by law enforcement.

“We are under assault,” Walz, a first-term governor elected from Minnesota’s Democratic-Farmer-Labor Party, told a briefing on Saturday. “Order needs to be restored. ... We will use our full strength of goodness and righteousness to make sure this ends.”

He said he believed a “tightly controlled” group of outsiders, including white supremacists and drug cartel members, were instigating some of the violence in Minnesota’s largest city, but he did not give specific evidence of this when asked by reporters.

As many as 80% of those arrested were from outside the state, Walz said. But detention records show just eight non-Minnesota residents have been booked into the Hennepin County Jail since Tuesday, and it was unclear whether all of them were arrested in connection with the Minneapolis unrest.

The Republican Trump administration suggested civil disturbances were being orchestrated from the political left.

“In many places, it appears the violence is planned, organized and driven by anarchic and left extremist groups - far-left extremist groups ... many of whom travel from outside the state to promote violence,” U.S. Attorney William Barr said in a statement.

In an extraordinary move, the Pentagon said it put military units on a four-hour alert to be ready if requested by Walz to help keep the peace.

Activists staged another round of protests on Saturday in at least a dozen major U.S. cities coast to coast, including Seattle, Los Angeles, Chicago, Cleveland, Dallas, Atlanta, New York and Atlanta.

In the nation’s capital, hundreds of demonstrators assembled near the Justice Department headquarters, then marched toward the U.S. Capitol, chanting, “Black lives matter,” and “I can’t breathe,” a rallying cry echoing Floyd’s dying words.

Many later ended up near the White House, where they faced off with shield-carrying police, some mounted on horseback.

The streets of Minneapolis were largely quiet during daylight on Saturday, though several National Guard armoured personnel carriers were seen rolling through town.

On Friday, in defiance of a newly imposed curfew, Minneapolis protesters took to the streets for a fourth night - albeit in smaller numbers than before - despite the announcement hours earlier of murder charges filed against Derek Chauvin, the policeman seen in video footage kneeling on Floyd’s neck.

Three other officers fired from the police department with Chauvin on Tuesday are also under criminal investigation in the case, prosecutors said.

The video of Floyd’s arrest - captured by an onlooker’s cellphone as he repeatedly groaned, “please, I can’t breathe” before becoming motionless - triggered an outpouring of rage that civil rights activists said has long simmered in Minneapolis and cities across the country over persistent racial bias in the U.S. criminal justice system.

‘PAINS ME SO MUCH’

The mood was sombre on Saturday in the Minneapolis neighbourhood of Lyndale, where dozens of people surveyed the damage while sweeping up broken glass and debris.

“It pains me so much,” said Luke Kallstrom, 27, a financial analyst, standing in the threshold of a fire-gutted post office. “This does not honour the man who was wrongfully taken away from us.”

Some of Friday’s most chaotic scenes were in the New York City borough of Brooklyn, where police armed with batons and pepper spray made more than 200 arrests in sometimes violent clashes. Several officers were injured, police said.

In Washington, President Donald Trump said on Saturday that if protesters who gathered the night before in Lafayette Square, across from the White House, had breached the fence, “they would have been greeted with the most vicious dogs, and most ominous weapons, I have ever seen.”

CHAOS IN ATLANTA

In Atlanta, Bernice King, the youngest daughter of slain civil rights icon Martin Luther King Jr., urged people to go home on Friday night after more than 1,000 protesters marched to the state capitol and blocked traffic on an interstate highway.

The demonstration turned violent at points. Fires burned near the CNN Center, the network’s headquarters, and windows were smashed at its lobby. Several vehicles were torched, including at least one police car.

Rapper Killer Mike, in an impassioned speech flanked by the city’s mayor and police chief, also implored angry residents to stay indoors and to mobilize to win at the ballot box.

“But it is not time to burn down your own home.”

Floyd, a Houston native who had worked security for nightclubs, was arrested on suspicion of trying to pass counterfeit money at a store to buy cigarettes on Monday evening. Police said he was unarmed. An employee who called for help had told a police dispatcher that the suspect appeared to be intoxicated.

In a striking coincidence, Floyd and Chauvin had both worked security at the same Latin nightclub in Minneapolis, though it was unlikely they ever interacted, former owner Maya Santamaria, who sold the El Nuevo Rodeo club in January, told Reuters.

Santamaria said Floyd worked inside the club on certain nights, supporting other staff with security. She said Chauvin, who worked outside the club as an off-duty cop for 16 years, had a reputation for roughing up customers, but she considered him responsible and a friend.
