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.

Washington, Aug 4: US President Donald Trump gave popular Chinese-owned video app TikTok six weeks to sell its US operations to an American company, saying Monday it would be "out of business" otherwise, and that the government wanted a financial benefit from the deal.

"It's got to be an American company... it's got to be owned here," Trump said. "We don't want to have any problem with security."

Trump said that Microsoft was in talks to buy TikTok, which has as many as one billion worldwide users who make quirky 60-second videos with its smartphone app.

But US officials say the app constitutes a national security risk because it could share millions of Americans' personal data with Chinese intelligence.

Trump gave the company's Chinese parent ByteDance until mid-September to strike a deal.

"I set a date of around September 15, at which point it's going to be out of business in the United States," he said.

Whatever the price is, he said, "the United States should get a very large percentage of that price because we're making it possible."

Trump compared the demand for a piece of the pie to a landlord demanding under-the-table "key money" from a new tenant, a practice widely illegal including in New York, where the billionaire president built his real estate empire.

"TikTok is a big success, but a big portion of it is in the country," he said. "I think it's very fair."

But Trump also threw a surprise new condition in any deal, saying the sale of TikTok's US business would have to result in a significant payout to the US Treasury for initiating it.

"A very substantial portion of that price is going to have to come into the Treasury of the United States, because we're making it possible for this deal to happen," Trump told reporters.

"They don't have any rights unless we give it to them," he said.

Sell or shut down

The pressure for a sale of TikTok's US and international business, based in Los Angeles, left the company and ByteDance facing tough decisions.

Trump has made TikTok the latest front in the ongoing political and trade battles between Washington and Beijing.

The app has been under formal investigation on US national security grounds because it collects large amounts of personal data on all its users and is legally bound to share that with authorities in Beijing if they demand it.

Both its huge user base and its algorithm for collecting data make it hugely valuable.

But being forced by the US government to sell at least its US business or be shut down -- and to then split the sale price with the US Treasury as Trump is demanding -- was an almost unheard-of tactic.

Shutting down could force users to switch to competitors, and many content creators are already encouraging followers to follow them on other social media platforms.

"The most obvious beneficiaries are Snapchat, Facebook and Twitter, with Snapchat likely being the biggest beneficiary," said investment analysts at Lightshed Partners.

Earlier Monday, ByteDance founder Zhang Yiming acknowledged the hefty pressure and said in a letter to staff, reported by Chinese media, that they were working around-the-clock "for the best outcome."

"We have always been committed to ensuring user data security, as well as the platform neutrality and transparency," Zhang said.

However, he said, the company faces "mounting complexities across the geopolitical landscape and significant external pressure."

He said the company must confront the challenge from the United States, though "without giving up exploring any possibilities."

According to Britain's The Sun newspaper Monday, as a possible consequence of the pressure, ByteDance is planning to relocate TikTok's global operations to Britain.

Pushing back

China's foreign ministry pushed back Monday, calling Washington hypocritical for demanding TikTok be sold.

"The US is using an abused concept of national security and, without providing any evidence, is making presumptions of guilt and issuing threats to relevant companies," said spokesman Wang Wenbin.

"This goes against the principle of market economy and exposes the hypocrisy and typical double standards of the US in upholding so-called fairness and freedom," he added.

Washington, Jan 3: US President Donald Trump ordered the killing of Iran Revolutionary Guards commander Qasem Soleimani, who died in Baghdad "in a decisive defensive action to protect US personnel abroad," the Pentagon said Thursday.

"General Soleimani was actively developing plans to attack American diplomats and service members in Iraq and throughout the region. General Soleimani and his Quds Force were responsible for the deaths of hundreds of American and coalition service members and the wounding of thousands more," the Department of Defense said.

Following Soleimani's death, Trump tweeted an image of the US flag without any further explanation.

"US' act of international terrorism, assassinating General Soleimani—the most effective force fighting Daesh (ISIS), Al Nusrah,Al Qaeda, is extremely dangerous & foolish escalation. US bears responsibility for all consequences of rogue adventurism." said Iran Foreign Minister Javad Zarif.

Jul 3: China under President Xi Jinping has stepped up its "aggressive" foreign policy toward India and "resisted" efforts to clarify the Line of Actual Control that prevented a lasting peace from being realised, according to a report released by a US Congress appointed commission.

The armies of India and China have been locked in a bitter standoff at multiple locations in eastern Ladakh for the last seven weeks, and the tension escalated after 20 Indian soldiers were killed in a violent clash in the Galwan Valley on June 15.

“Under General Secretary of the Chinese Communist Party (CCP) Xi Jinping, Beijing has stepped up its aggressive foreign policy toward New Delhi. Since 2013, China has engaged in five major altercations with India along the Line of Actual Control (LAC),” said a brief issued by US-China Economic and Security Review Commission.

"Beijing and New Delhi have signed a series of agreements and committed to confidence-building measures to stabilise their border, but China has resisted efforts to clarify the LAC, preventing a lasting peace from being realised,” said the report and was prepared at the request of the Commission to support its deliberations.

Authored by Will Green, a Policy Analyst on the Security and Foreign Affairs Team at the Commission, the report says that the Chinese government is particularly fearful of India’s growing relationship with the United States and its allies and partners.

“The latest border clash is part of a broader pattern in which Beijing seeks to warn New Delhi against aligning with Washington,” it said.

After Xi assumed power in 2012, there was a significant increase in clashes, despite the fact that he met Prime Minister Narendra Modi several times and Beijing and New Delhi have agreed to a series of confidence-building mechanisms designed to mitigate tensions.

Prior to 2013, the last major border clash was in 1987. The 1950s and 1960s were a particularly tense period, culminating in 1962 with a war that left thousands of soldiers dead on both sides, according to the records of China's People's Liberation Army, the report said.

“The 2020 skirmish is in line with Beijing’s increasingly assertive foreign policy. The clash came as Beijing was aggressively pressing its other expansive sovereignty claims in the Indo-Pacific region, such as over Taiwan and in the South and East China seas,” it said.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Several weeks before the clash in the Galwan Valley, Chinese Defence Minister Wei Fenghe called on Beijing to “use fighting to promote stability” as the country’s external security environment worsened, a potential indication of China’s intent to proactively initiate military tensions with its neighbours to project an image of strength, the report said.
