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.

Mar 6: UK stocks fell again on Friday as growing economic risks from the coronavirus outbreak shattered investor confidence, with Britain recording its first death from the pathogen.

A 1.5% fall for the FTSE 100 erased the blue-chip index's gains from earlier this week. Export-heavy companies have now lost over $230 billion in value since the epidemic sparked a worldwide rout last week.

The domestically focussed mid-cap index was down 1.9%.

Cruise operator Carnival dropped 4.2% to its lowest level since 2012, a day after its Grand Princess ocean liner was barred from returning to its home port of San Francisco on virus fears.

Britain said an older person with underlying health problems had succumbed to the flu-like virus on Thursday, while the number of infections jumped to 115.

In company news, drug maker AstraZeneca fell 1% after it said its treatment for a form of bladder cancer failed to meet the main goal of improving overall survival in patients in a late-stage study.

Tokyo, Jul 27: Gold hit an all-time high on Monday as tit-for-tat consulate closures in China and the United States rattled investors, boosting the allure of safe-haven assets, although sentiment was mixed with tech gains supporting some Asian stocks.

MSCI's ex-Japan Asia-Pacific index rose 1.3 percent as Taiwan's TSMC, Asia's third-largest company by market capitalisation, rose almost 10 percent.

The chipmaker's gains boosted other tech stocks in the region and came after rival Intel signalled it may give up manufacturing its own components due to delays in new 7-nanometer chip technology.

Also soothing sentiment, Chinese shares eked out gains after big falls late last week, with CSI300 index rising 0.5 percent.

S&P500 futures were last up 0.4 percent in choppy trade while Japan's Nikkei fell 0.5 percent, resuming trade after a long weekend and catching up with falls in global shares late last week.

Global shares had lost steam last week after Washington ordered China's consulate in Houston to close, prompting Beijing to react in kind by closing the US consulate in Chengdu.

US Secretary of State Mike Pompeo took fresh aim at China last week, saying Washington and its allies must use "more creative and assertive ways" to press the Chinese Communist Party to change its ways.

"US President (Donald) Trump used to say China's President Xi Jinping is a great leader. But now Pompeo's wording is becoming so aggressive that markets are starting to worry about further escalation," said Norihiro Fujito, chief investment strategist at Mitsubishi Securities.

Gold rose 1.0 percent to a record high of $1,920.9 per ounce, surpassing a peak touched in September 2011, as Sino-US tensions boosted the allure of safe-haven assets, especially those not tied to any specific country.

The yellow metal is also helped by aggressive monetary easing adopted by many central banks around the world since the pandemic plunged the global economy into a recession.

Some investors fret such an unprecedented level of money-printing could eventually lead to inflation.

MORE STIMULUS

Hopes of a quick US economic recovery are fading as coronavirus infections showed few signs of slowing.

That means the economy could capitulate without fresh support from the government, with some of earlier steps such as enhanced jobless benefits due to expire this month.

Investors hope US Congress will agree on a deal before its summer recess but there are some sticking points including the size of the stimulus and enhanced unemployment benefits.

US Treasury Secretary Steve Mnuchin said the package will contain extended unemployment benefits with 70 percent "wage replacement".

Democrats, who control the House of Representatives, want enhanced benefits of $600 per week to be extended and look to much bigger stimulus compared with the Republicans' $1 trillion plan.

Investors are looking to corporate earnings from around the world for hints on the pace of recovery in the global economy.

"It looks like rising coronavirus cases are starting to slow down recovery in many countries," said Masahiro Ichikawa, senior strategist at Sumitomo Mitsui DS Asset Management.

Concerns about the US economic outlook started to weigh on the dollar, reversing its inverse correlation with the economic well-being over the past few months.

The dollar index dropped 0.3 percent to its lowest level in nearly two years.

The euro gained 0.3 percent to $1.1693, hitting a 22-month high of $1.16590 as sentiment on the common currency improved after European leaders reached a deal on a recovery fund in a major step towards more fiscal co-operation.

Against the yen, the dollar slipped 0.5 percent to 105.605 yen, a four-month low while the British pound hit a 4 1/2-month high of $1.2832.

Oil prices dipped on worries about the worsening Sino-US relations.

Brent futures fell 0.46 percent to $43.14 per barrel while US crude futures lost 0.44 percent to $41.11.
