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.

Washington, Apr 5: US President Donald Trump on Saturday said that he has requested Prime Minister Narendra Modi to supply Hydroxychloroquine tablets that can be used to treat COVID-19 patients.

"After call today with Indian Prime Minister Narendra Modi, India is giving serious consideration to releasing the hold it put on a US order for hydroxychloroquine," Trump announced at the White House Coronavirus task force briefing that he requested PM Narendra Modi for more Hydroxychloroquine tablets.

President Trump did not shy away from saying he too will take a tablet of hydroxychloroquine after announcing that he has requested Prime Minister during his telephonic conversation earlier today to lift a hold on the US order of the medicine.

"I may take it too, will have to talk to my doctors," he added.

"India makes a lot of it. They need a lot too for their billion-plus people. 

The hydroxychloroquine, the anti-malaria drug will be released through the Strategic National Stockpile for treatment," he said.

"I said I would appreciate if they would release the amounts that we ordered" of hydroxychloroquine, he said.

The Indian government has put on hold the export of anti-malarial drug hydroxychloroquine and its formulations.

Prime Minister Narendra Modi said on Twitter, "Had an extensive telephone conversation with President @realDonaldTrump. 

We had a good discussion, and agreed to deploy the full strength of the India-US partnership to fight COVID-19."

Beijing, May 25: China has reported 51 new coronavirus cases including 40 asymptomatic infections, majority of them in the contagion's first epicentre Wuhan, where over six million tests have been conducted in the last 10 days, health officials said on Monday.

The country's National Health Commission (NHC) said that 11 new imported cases were reported on Sunday.

While no new domestically-transmitted COVID-19 cases were reported in China on Sunday, 11 imported cases including 10 in the Inner Mongolia Autonomous Region and one in Sichuan province were reported, the NHC said in its daily report.

Out of the 40 new asymptomatic cases, 38 were reported in Wuhan, which is currently undergoing mass testing of its over 11.2 million people after a spike in the asymptomatic cases.

Currently, 396 people with asymptomatic symptoms are under medical observation in China, including 326 in Wuhan, according to the health authority.

Asymptomatic cases refer to the patients who have tested COVID-19 positive but develop no symptoms such as fever, cough or sore throat. However, they pose a risk of spreading the disease to others.

Wuhan, which earlier had over 50,000 cases between January and March, started a campaign on May 14 to expand the nucleic acid testing in order to better know the number of asymptomatic cases or people who show no clear symptoms despite carrying the virus.

According to the latest figures released by the Wuhan municipal health commission, the city conducted more than 6 million nucleic acid tests between May 14 and 23.

On Saturday, the city carried out nearly 1.15 million tests, state-run Xinhua news agency reported on Monday.

Nucleic acid testing is a molecular technique for screening blood donations to reduce the risk of transfusion transmitted infections.

As of Sunday, a total of 82,985 confirmed COVID-19 cases have been reported in China with 4,634 fatalities, the NHC added.

Jan 23: Pakistan's Prime Minister Imran Khan called on Wednesday for the United Nations to help mediate between nuclear armed India and Pakistan over the disputed territory of Kashmir.

"This is a potential flashpoint," Khan said during a media briefing at the annual meeting of the World Economic Forum in Davos, Switzerland, adding that it was time for the "international institutions ... specifically set up to stop this" to "come into action".

The Indian government in August revoked the constitutional autonomy of Indian-administered Kashmir, splitting the Muslim-majority region into two federal territories in a bid to integrate it fully with the rest of the country.

Kashmir is claimed in full by both India and Pakistan. The two countries have gone to war twice over it, and both rule parts of it. India's portion has been plagued by separatist violence since the late 1980s.

Khan said his biggest fear was how New Delhi would respond to ongoing protests in India over a citizenship law that many feel targets Muslims.

"We're not close to a conflict right now ... What if the protests get worse in India, and to distract attention from that, what if ..."

The prime minister said he had discussed the prospect of war between his country and India in a Tuesday meeting with US President Donald Trump. Trump later said he had offered to help mediate between the two countries.

Khan said Pakistan and the United States were closer in their approach to the Taliban armed rebellion in Afghanistan than they had been for many years. He said he had never seen a military solution to that conflict.

"Finally the position of the US is there should be negotiations and a peace plan."

In a separate on-stage conversation later on Wednesday, Khan said he had told Trump in their meeting that a war with Iran would be "a disaster for the world". Trump had not responded, Khan said.

Khan made some of his most straightforward comments when asked why Pakistan has been muted in defence of Uighurs in China.

China has been widely condemned for setting up complexes in remote Xinjiang province that Beijing describes as "vocational training centres" to stamp out ""extremism and give people new skills.

The United Nations says at least one million ethnic Uighurs and other Muslims have been detained.

When pressed on China's policies, Khan said Pakistan's relations with Beijing were too important for him to speak out publicly.

"China has helped us when we were at rock bottom. We are really grateful to the Chinese government, so we have decided that any issues we have had with China we will handle privately."
