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.

May 12: Several Indians in the US, either on the H-1B work visa or Green Card having children who are American citizens by birth, are being prevented from travelling to India aboard the special repatriation flights being run by Air India amidst the coronavirus-linked global travel restrictions.

According to the regulations issued by the Indian government last month and updated last week, visas of foreign nationals and OCI cards, that provide visa-free travel privileges to the people of Indian-origin, have been suspended as part of the new international travel restrictions.

For some of the Indian citizens like the Pandey couple in New Jersey (name and place changed at request), it's a double whammy. Having lost their H-1B job, they have to go back to India within the stipulated 60 days as required by law. The couple has two kids aged one and six years who are American citizens.

In the wee hours of Monday, they had to return from Newark airport as Air India refused to give their kids a ticket to fly to India along with them, despite them having a valid Indian visa. The young mother and father are Indian citizens.

They said that the officials from Air India and (Indian) Consulate (in New York) were very cooperative.

But they could not do anything as their hands were tied by the latest regulation issued by the Indian government, a shocked Ratna Pandey told PTI.

"I would like to urge the Indian government to reconsider their decision on the humanitarian basis," said the Indian national who has lost her job but could not leave the US within the stipulated 60 days to avoid any future visa complications.

She now plans to make an appeal to the US Citizenship and Immigration Services (USCIS) to extend their stay.

Last month, H-1B visa holders, mostly Indians, launched a White House petition urging US President Donald Trump to extend their permissible stay from 60 to 180 days after job loss. However, there has been no decision from the White House so far.

While there is no official statistics of how many Indian H-1B visa holders have lost their jobs, it is believed to be substantial.

The US, due to the coronavirus pandemic, is experiencing an unprecedented unemployment rate and more than 33 million Americans have lost their jobs in the last two months. Given this massive job loss, Indians, who have lost their jobs, are unlikely to get one and thus many would have no other option but to travel back home.

In the case of single mother Mamta (name changed), the situation is graver as her son is just three-month old. Only she was given the ticket and the infant was not allowed to fly along with her because he carried an American passport.

"I would like to request the Indian government to let us fly back home. I don't want to stay in the US any longer," she told PTI hours after being prevented from boarding her hometown Ahmedabad-bound flight from Newark on Sunday.

"I am alone here. I don't have a relative here. It's a difficult situation," she said.

"Vande Bharat Mission is a humanitarian mission. But this is certainly inhuman," said Rakesh Gupta (name changed) from Washington DC.

An H-1B professional, Gupta has lost his job and needs to return to India within the stipulated 60 days. He and his wife, Geeta (name changed) being Indian citizens, received the confirmation of their seats in the flight but have been told that their two-and-a-half-year-old daughter cannot travel with them as she carried an OCI card.

"I don't believe this," he said.

Unlike the Pandey couple and Mamta, who had made the payment of USD 1,361 per ticket for their flight back home, Rakesh has not made the payment. Air India has said that the money would be refunded.

All the three Indian citizens requested the Indian government to help them travel back home by making necessary changes in the current regulations.

As per a recent government notification, all existing Indian visa holders, and visa-free travel facility, granted to OCI card holders who are not in India, have been suspended till restrictions on international air travel remains.

New York-based community leader Prem Bhandari said that the May 5 travel advisory has created multiple painful issues for the OCI card holders in the US and also to Indian citizens who are either on Green Card or H-1B visas and want to travel back home, but cannot leave their kids who are Americans by birth.

"We would like to express our disappointment with the discrimination between OCIs and citizens in respect of entering India at this critical stage when many OCIs have lawfully built their homes, families and businesses in India," Bhandari said in a letter to Union Home Secretary Ajay Kumar Bhalla on Monday.

New Delhi, Mar 24: Reports of a person in China dying due to a virus called hantavirus have spread panic at a time when the world is battling the pandemic of novel coronavirus, which began in China.

The novel coronavirus has killed over 16,000 people around the world and the outbreak is yet to be brought under control.

This morning, hantavirus became one of the top trends on Twitter after the Chinese state media tweeted about one person in the country dying due the virus. However, it turns out, hantavirus is not a new virus and has been infecting humans for decades.

Global Times, a state-run English-language newspaper, wrote on Twitter on Tuesday, "A person from Yunnan Province died while on his way back to Shandong Province for work on a chartered bus on Monday. He was tested positive for hantavirus. Other 32 people on bus were tested."

Global Times's hantavirus report on Twitter has been shared over 6,000 times.

On Tuesday, hantavirus was one of the top trends on Twitter.

WHAT IS HANTAVIRUS?

Some people are calling it a new virus but so is not the case. United States's National Center for Biotechnology Information (NCBI) in a journal writes that currently, the hantavirus genus includes more than 21 species.

"Hantaviruses in the Americas are known as 'New World' hantaviruses and may cause hantavirus pulmonary syndrome [HPS]," CDC says. "Other hantaviruses, known as 'Old World' hantaviruses, are found mostly in Europe and Asia and may cause hemorrhagic fever with renal syndrome [HFRS]."

Any man, woman, or child who is around mice or rats that carry harmful hantaviruses can get HPS.

People get HPS when they breath in hantaviruses. This can happen when rodent urine and droppings that contain a hantavirus are stirred up into the air. People can also become infected when they touch mouse or rat urine, droppings, or nesting materials that contain the virus and then touch their eyes, nose, or mouth. They can also get HPS from a mouse or rat bite.

In the US, 10 confirmed cases of hantavirus infection in people who visited Yosemite National Park in California, US, in November 2012, were reported. Similarly, in 2017, CDC assisted health officials in investigating an outbreak of Seoul virus infection that infected 17 people in seven states.

WHAT ARE THE SYMPTOMS OF HANTAVIRUS?

If people get HPS, they will feel sick one to five weeks after they were around mice or rats that carried a hantavirus.

At first people with HPS will have:

Fever
Severe muscle aches
Fatigue

After a few days, they will have a hard time breathing. Sometimes people will have headaches, dizziness, chills, nausea, vomiting, diarrhoea, and stomach pain.

Usually, people do not have a runny nose, sore throat, or a rash.
