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.

New Delhi, May 28: Twitter CEO Jack Dorsey today reinforced his stance on pointing out "incorrect or disputed information about elections globally", a day after US President Donald Trump threatened to shutter social media over Twitter's actions on his posts.

Mr Dorsey appealed to "leave our employees out of this" as the face-off with Mr Trump is likely to escalate.

"Fact check: there is someone ultimately accountable for our actions as a company, and that's me. Please leave our employees out of this. We'll continue to point out incorrect or disputed information about elections globally. And we will admit to and own any mistakes we make," Mr Dorsey tweeted.

"This does not make us an 'arbiter of truth.' Our intention is to connect the dots of conflicting statements and show the information in dispute so people can judge for themselves. More transparency from us is critical so folks can clearly see the why behind our actions," said the Twitter CEO.

"Per our Civic Integrity policy (https://help.twitter.com/en/rules-and-policies/election-integrity-policy), the tweets yesterday may mislead people into thinking they don't need to register to get a ballot (only registered voters receive ballots). We're updating the link on

@realDonaldTrump tweet to make this more clear," Mr Dorsey tweeted.

Twitter had tagged two of Mr Trump's tweets in which he claimed that more mail-in voting would lead to what he called a "rigged election" this November. There is no evidence that attempts are being made to rig the election, and under the tweets Twitter posted a link which read: "Get the facts about mail-in ballots."

Five states in the US already conduct elections primarily by mail-in vote: Utah, Colorado, Hawaii, Washington and Oregon.

For years, Twitter has been accused of ignoring the US President's violation of platform rules with his daily, often hourly barrages of personal insults and inaccurate information sent to more than 80 million followers, news agency AFP reported.

But Twitter's slap on the wrist was enough to drive Mr Trump into a tirade - on Twitter - in which "Republicans feel that Social Media Platforms totally silence conservatives voices. We will strongly regulate, or close them down, before we can ever allow this to happen," Mr Trump said.

He said that an increase in mail-in ballots - seen in some states as vital for allowing people to avoid crowds during the COVID-19 pandemic - will undermine the election.

"It would be a free for all on cheating, forgery and the theft of Ballots," wrote Mr Trump, whose re-election campaign has been knocked off track by the coronavirus crisis. His torrent of angry tweets earned a top-10 trending hashtag: #TrumpMeltdown.

Facebook chief Mark Zuckerberg also waded in to the row, telling Fox News that his social network - still the biggest in the world - has a different policy. "I just believe strongly that Facebook should not be the arbiter of truth of everything that people say online," Mr Zuckerberg said in a snippet of the interview posted online Wednesday by Fox.

"I think, in general, private companies, especially these platform companies, shouldn't be in the position of doing that," he said.

Berlin, Mar 28: The number of confirmed coronavirus infections worldwide topped 600,000 on Saturday as new cases stacked up quickly in Europe and the United States and officials dug in for a long fight against the pandemic.

The latest landmark came only two days after the world passed half a million infections, according to a tally by John Hopkins University, showing that much work remains to be done to slow the spread of the virus. It showed more than 602,000 cases and a total of over 27,000 deaths.

While the U.S. now leads the world in reported infections — with more than 104,000 cases — five countries exceed its roughly 1,700 deaths: Italy, Spain, China, Iran and France.

“We cannot completely prevent infections at this stage, but we can and must in the immediate future achieve fewer new infections per day, a slower spread,” German Chancellor Angela Merkel, who is in quarantine at home after her doctor tested positive for the virus, told her compatriots in an audio message. “That will decide whether our health system can stand up to the virus.”

The virus already has put health systems in Italy, Spain and France under extreme strain. Lockdowns of varying severity have been introduced across Europe. Merkel's chief of staff, Helge Braun, said that Germany — where authorities closed nonessential shops and banned gatherings of more than two in public — won't relax its restrictions before April 20.

As the epicenter has shifted westward, the situation has calmed in China, where some restrictions on people's lives have now been lifted. Six subway lines restored limited service in Wuhan, where the virus first emerged in December, after the city had its official coronavirus risk evaluation downgraded from high to medium on Friday. Five districts of the city of 11 million people had other restrictions on travel loosened after their risk factor was downgraded to low.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. But for others, especially older adults and people with existing health problems, the virus can cause more severe illness, including pneumonia, and lead to death.

More than 130,000 people have recovered, according to Johns Hopkins' tally.

In one way or another, the effects of the COVID-19 outbreak have been felt by the powerful and the poor alike.

On Friday, British Prime Minister Boris Johnson became the first leader of a major country to test positive for the virus. He said he would continue to work from self-quarantine.

Countries are still scrambling bring home some citizens stranded abroad by border closures and a near-shutdown of flights. On Saturday, 174 foreign tourists and four Nepali nationals on the foothills of Mount Everest were flown out days after being stranded on the only airstrip serving the world's highest mountain.

In neighboring India, authorities sent a fleet of buses to the outskirts of the capital to meet an exodus of migrant workers desperately trying to reach their home villages during the world's largest lockdown.

Thousands of people, mostly young male day laborers but also families, had fled their New Delhi homes after Prime Minister Narendra Modi announced a 21-day lockdown that began on Wednesday and effectively put millions of Indians who live off daily earnings out of work.

In a possibly hopeful sign, the U.S. Food and Drug Administration cleared a new rapid test from Abbott Laboratories, which the company says can detect the coronavirus in about 5 minutes. Medical device maker Abbott announced the emergency clearance of its cartridge-based test Friday night, saying the test delivers a negative result in 13 minutes when the virus is not detected.

While New York remained the worst-hit city in the U.S., Americans braced for worsening conditions elsewhere, with worrisome infection numbers being reported in New Orleans, Chicago and Detroit.

New Orleans’ sprawling Ernest N. Morial Convention Center, along the Mississippi River, was being converted into a massive hospital as officials prepared for thousands more patients than they could accommodate.

In New York, where there are more than 44,000 cases statewide, the number of people hospitalized with COVID-19 passed 6,000 on Friday, double what it had been three days earlier.

Gov. Andrew Cuomo called for 4,000 more temporary beds across New York City, where the Jacob K. Javits Convention Center has already been converted into a hospital.

The struggle to defeat the virus will take “weeks and weeks and weeks,” Cuomo told members of the National Guard working at the Javits Center.

President Donald Trump invoked the Defense Production Act on Friday, ordering General Motors to begin manufacturing ventilators. Trump had previously rejected Cuomo's pleas for tens of thousands more of the machines and the governor's calls to implement the Korean War-era production law.

Trump signed a $2.2 trillion stimulus package, after the House approved the sweeping measure by voice vote. Lawmakers in both parties lined up behind the law to send checks to millions of Americans, boost unemployment benefits, help businesses and toss a life preserver to an overwhelmed health care system.

Dr. John Brooks of the U.S. Centers for Disease Control and Prevention warned Americans remained “in the acceleration phase” of the pandemic and that all corners of the country were at risk.

"There is no geographic part of the United States that is spared from this," he said.

Islamabad, Feb 26: Islamabad on Tuesday declared former Prime Minister Nawaz Sharif an absconder while simultaneously denying extending bail to him.

The federal cabinet presided over by Prime Minister Imran Khan, cited that Sharif failed to provide required medical reports and has violated the bail terms.

The government has also decided to freeze gas and electricity tariffs for the next four months, The Dawn reported.

"After Nawaz Sharif failed to submit his medical report of any hospital in London, the medical board rejected a medical certificate sent by him and [the government] declared him an absconder. From today, Nawaz Sharif is an absconder according to the law of land and if he does not return to the country he will be declared a proclaimed offender," said Dr Firdous Ashiq Awan, Special Assistant to the Prime Minister on Information, in a press conference.

She further asserted that the Punjab government, which was authorized by the Islamabad High Court (IHC) to decide Sharif's case on medical grounds, had written several letters asking him to submit his medical report from any hospital in London. However, he failed to do so and only sent a certificate that was not accepted by the medical board.

"If he (Nawaz Sharif) is seriously ill then why a comprehensive medical report is not being submitted to the medical board," Firdous added.

Further, she said that the office of the opposition leader was also waiting for his younger brother and Leader of the Opposition in the National Assembly Shahbaz Sharif, who was also staying in London for 'no reason'.

"He is getting a monthly salary and enjoying luxurious offices and other perks and privileges but not performing his duties required by his office and the people. Shahbaz Sahib, return to the country and justify your salary and other benefits being given from taxpayers' money," Firdous added.

On October 29 last year, the IHC granted bail for eight weeks to Sharif, who was convicted and disqualified in corruption cases, on medical grounds.

Sharif left Pakistan for London along with Shahbaz on November 19, 2019, for his medical treatments there.
