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.

Beijing, Jun 16: The coronavirus situation in China's capital is "extremely severe", a city official warned Tuesday, as 27 new infections were reported from Beijing where a new cluster has sparked a huge trace-and-test programme.

The COVID-19 resurgence -- believed to have started at the sprawling Xinfadi wholesale food market in the capital -- has sparked alarm as China had largely brought its outbreak under control through mass testing and lockdowns imposed earlier in the year.

The new cases took the number of confirmed infections in Beijing over the past five days to 106, as authorities locked down almost 30 communities in the city and tested tens of thousands of people.

"The epidemic situation in the capital is extremely severe," Beijing city spokesman Xu Hejian warned at a press conference.

The World Health Organization had already expressed concern about the cluster, pointing to Beijing's size and connectivity.

Officials in the capital have said they will test stall owners and managers at all of the city's food markets, restaurants and government canteens.

Beijing's coronavirus testing capacity has been expanded to 90,000 a day, according to China's official news agency Xinhua.

On Tuesday, the capital's transport commission banned taxi- and ride-hailing services from driving out of the city, Xinhua reported, in another move to try and contain the new outbreak.

All indoor sports and entertainment venues in Beijing were ordered to shut on Monday, and some other cities across China warned they would quarantine those arriving from the capital.

The National Health Commission also reported four new domestic infections in Hebei province, which surrounds Beijing, and a case reported in southwestern Sichuan province was linked to the Beijing cluster.

Authorities were also racing to track people from Beijing who had travelled to other parts of China, and those who visited the capital have been encouraged to get tested.

Beijing spokesman Xu said: "High-risk people who have left Beijing must inform local authorities immediately."

Market inspections

Authorities shut down another market on Tuesday -- Tiantaohonglian in the central Xicheng district -- after one employee there was diagnosed with COVID-19, state broadcaster CCTV reported.

Seven residential estates surrounding that market were also locked down.

In total, Beijing officials said Tuesday they have disinfected 276 agricultural markets, closed 11 markets, and disinfected more than 33,000 food and beverage businesses in a bid to stamp out the new cluster.

Officials had warned Sunday that since May 30, 200,000 people had visited the Xinfadi market -- the original site of the new outbreak.

More than 8,000 workers from Xinfadi have been tested and sent to centralised quarantine facilities.

Until this recent outbreak, most of China's cases in recent months were nationals returning home as the pandemic spread to other countries.

China's Center for Disease Control and Prevention said Monday that the virus strain found in the Beijing outbreak was a "major epidemic strain in the European countries".

While the virus was detected on chopping boards used to handle imported salmon at Xinfadi, "it does not clearly or definitely indicate it's from imported seafood", Wu Zunyou, the body's chief epidemiologist, said in an interview with state broadcaster CCTV.

"Ever since new cases suddenly emerged in Beijing, we have tried to figure out the reasons for the outbreak since there were no COVID-19 cases found over the past two months," Wu Zunyou said.

"We came up with several possibilities, and the most likely one is that the carrier of the novel coronavirus comes from outside China or other parts of China and brought it here."

On Tuesday, another eight imported cases were reported.

New York, Jan 11: The United Nations Security Council (UNSC) on Friday renewed a six-year-long cross-border humanitarian aid deliveries mechanism into Syria.

According to Sputnik, the Security Council voted in favour of a resolution on Friday that allows cross border deliveries to be conducted via Turkey, preserving two checkpoints and excluding the Al-Yarubiyah border crossing with Iraq and the Al-Ramtha crossing with Jordan, until July 10, 2020.

Russia proposed to amend the adopted resolution by replacing a part of the draft which stipulates that humanitarian assistance into Syria should be delivered based on the principles of humanity, neutrality, impartiality and independence by the phrase that such aid should be provided "in accordance with the guiding principles of humanitarian emergency assistance, as contained in UNGA resolution 46/182."

The agreement was reached after Belgium and Germany decided to amend the original version of their joint resolution, which proposed keeping three points for cross-border deliveries into the Arab republic.

In December last year, the United Nations had said that over 235,000 people fled the Idlib region in the last two weeks after Russia and Syria launched airstrikes in a bid to take over the last major opposition bastion.

Russia backed Syria government launched a fresh assault to capture the province.

Syrian Bashar al-Assad regime, backed by Iran, has reportedly promised to take back the rebel-controlled area and broke a ceasefire that was announced in August.

They have since December 19 seized dozens of towns and villages from armed fighters amid clashes that have killed hundreds on both sides.

Islamabad, Feb 17: Prime Minister Imran Khan on Monday warned that Pakistan may face another refugee crisis if the international community failed to take notice of the current situation in India.

Speaking at the two-day refugee summit in Islamabad on 40 years of hosting Afghan refugees in Pakistan, he said India’s "ultranationalist ideology going unchecked could lead to destruction and the region could become a flashpoint", The Express Tribune quoted him as saying.

Khan said if the international community does not take notice of this situation, it will create another refugee crisis for Pakistan as Muslims of India will move to Pakistan.

"This is not the India of Jawaharlal Nehru and Mahatma Gandhi. The United Nations (UN) must play its role otherwise it will become a very big problem in the future," Duniya News quoted Khan as saying.

He said said that Prime Minister Narendra Modi’s statement that India can destroy Pakistan in 11 days is not a responsible statement by a premier of a nuclear state with a huge population, the paper reported.

Khan made the statement in the presence of visiting UN Secretary General Antonio Guterres, who was also attending the summit.

He said because of the "Hindutva" ideology, Kashmiris have been lockdown for over 200 days. He alleged under the same ideology, the BJP-led government passed two discriminatory nationalistic legislations, targeting 200 million Muslims in India.

Khan was referring to India's Citizenship (Amendment) Act and the revocation of the special status to Jammu and Kashmir.

The new citizenship law passed by the Indian Parliament in December 2019 offers citizenship to non-Muslim persecuted religious minorities from Pakistan, Bangladesh and Afghanistan.

The Indian government has maintained that the CAA is an internal matter of the country and stressed that the goal is to protect the oppressed minorities of neighbouring countries.

India revoked Jammu and Kashmir's special status on August 5. Reacting to India's move, Pakistan downgraded diplomatic ties with New Delhi and expelled the Indian High Commissioner.

India has always maintained that Jammu and Kashmir is its integral part and ruled out any third party mediation, including either from the UN or the US, saying it is a bilateral issue with Pakistan.
