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.

London, Feb 19: UK Home Secretary Priti Patel today announced the launch of the Britain's new points-based visa system, aimed at attracting the "brightest and the best" from the world, including from India, and cutting down numbers of cheap, low-skilled workers coming to the country.

The new system will come into force from January 1, 2021 at the end of the transition period after the UK's exit from the European Union (EU) last month, which will formally end free movement of people within the economic bloc for the UK as a non-member.

The new post-Brexit system, which will apply equally to the EU and non-EU countries like India, is based on assigning points for specific skills, qualifications, salaries and professions, with visas only awarded to those who gain enough points.

"Today is a historic moment for the whole country. We're ending free movement, taking back control of our borders and delivering on the people's priorities by introducing a new UK points-based immigration system, which will bring overall migration numbers down," said Ms Patel, the senior-most Indian-origin Cabinet minister.

"We will attract the brightest and the best from around the globe, boosting the economy and our communities, and unleash this country's full potential," Ms Patel, in charge of the UK's visa and immigration system, said.

The UK Home Office said the new system is a direct response to the 2016 referendum in favour of Brexit, which was seen as a vote to end the country's reliance on cheap migrant labour and reduce overall levels of migration with tighter security.

"The new single global system will treat the EU and non-EU citizens equally. It will give top priority to those with the highest skills and the greatest talents, including scientists, engineers and academics," the Home Office said.

The Global Talent Scheme, a fast-track visa to be in operation from Friday, will also apply to the EU citizens from next year to allow highly-skilled scientists and researchers to come to the UK without a job offer.

Professor Alice Gast, President of Imperial College London, said: "British science is global. The new post-study work and Global Talent visas will help us to attract the world's brightest students and researchers, wherever they come from."

"From the race to develop a coronavirus vaccine to clean energy, British science's international collaborations drive innovation and excellence."

The government said the points threshold for the new system will be carefully set to attract the talent the UK needs. Skilled workers will need to meet a number of relevant criteria, including specific skills and the ability to speak English, to be able to work in the UK. All applicants will be required to have a job offer and, in line with the Migration Advisory Committee''s (MAC) recommendations, the minimum salary threshold will be set at 25,600 pounds - lower than the previous 30,000 pounds level for Tier 2 work visas.

The new points-based system will also expand the skills threshold for skilled workers.

Those looking to live and work in the UK will need to be qualified up to A-level or equivalent, rather than degree-level under the current system. This will provide greater flexibility and ensure UK business has access to a wide pool of skilled workers, the Home Office said.

In line with the British Prime Minister Boris Johnson's manifesto commitment in the December 2019 General Election, there will be no specific route for low-skilled workers.

"It is estimated 70 per cent of the existing EU workforce would not meet the requirements of the skilled worker route, which will help to bring overall numbers down in future," the Home Office said.

Student visa routes will also be points-based and be opened up to EU citizens from next year.

Those wishing to study in the UK will need to demonstrate that they have an offer from an approved educational institution, that they can support themselves financially and that they speak English.

To address the specific labour concerns of the agricultural sector reliant on seasonal workers from the EU, the Seasonal Workers Pilot will be expanded in time for the 2020 harvest from 2,500 to 10,000 places.

EU citizens and other non-visa nationals will not require a visa to enter the UK when visiting the UK for up to six months.

However, the use of national identity cards will be phased out for travel to the UK and the Home Office highlighted that as part of its post-Brexit offer, those EU citizens resident in the UK by December 31 2020 can still apply to settle in the UK through the EU Settlement Scheme until June 2021.

Jan 7: Body of the senior Iranian military commander, Qasem Soleimani killed in a U.S. drone strike in Iraq last week, has arrived in his home town of Kerman in southeast Iran for burial, the official IRNA news agency said on Tuesday.

State TV broadcast live images of thousands of people in the streets of the town, many of them dressed in black, to mourn Soleimani's death.

Soleimani was widely seen as Iran’s second most powerful figure behind Supreme Leader Ayatollah Ali Khamenei, 80, who wept in grief along with hundreds of thousands of mourners who thronged the streets of Tehran for Soleimani’s funeral on Monday.

Khamenei led prayers at the funeral in the Iranian capital, pausing as his voice cracked with emotion. Soleimani, 62, was a national hero even to many who do not consider themselves supporters of Iran’s clerical rulers.

He was killed while leaving Baghdad airport last Friday. Mourners packed the streets, chanting: “Death to America!” - a show of national unity after anti-government protests in November in which many demonstrators were killed.

The crowd, which state media said numbered in the millions, recalled the masses gathered in 1989 for the funeral of the Islamic Republic’s founder, Ayatollah Ruhollah Khomeini.

The killing of Soleimani has prompted fears around the world of a broader regional conflict, as well as calls in the U.S. Congress for legislation to keep President Donald Trump from going to war against Iran.

Paris, Jun 29: More than half a million people have been killed by the novel coronavirus, nearly two thirds of them in the United States and Europe, according to an news agency tally at 2200 GMT Sunday based on official sources.

The official death count for the disease now stands at 500,390 deaths from 10,099,576 cases recorded worldwide. The United States has suffered the highest death count (125,747), followed by Brazil (57,622) and the United Kingdom (43,550).

The tallies, using data collected by AFP from national authorities and information from the World Health Organization (WHO), probably reflect only a fraction of the actual number of infections.

Many countries are testing only the most serious cases.
