The toilet system turning human waste into energy




Researchers at Singapore's Nanyang Technological University (NTU) have been working on ways to make towns and cities more sustainable by taking waste from housing and turning it into energy.

The team created a new type of toilet system which turns human waste into biogas - which can be used for cooking and generating electricity - and biodiesel.

Strike: ASUU Urges National Assembly to Block Govt Leakages


 The Academic Staff Union of Universities (ASUU) has urged the National Assembly to go beyond begging the union to call off its current strike and block leakages in government expenditure to ensure provision of needed infrastructure.

ASUU also criticised the Vice Chairman, Senate Committee on Education, Professor Sola Adeyeye for over his comments on why a professor should demand payment to supervise postgraduate students.

A release signed by the ASUU chairman at the University of Ibadan, Dr. Olusegun Ajiboye, said Professor Adeyeye was ignorant of the current situation in the universities.

Ajiboye also dismissed comments by Senate President, David Mark, that ASUU would lose public sympathy if it does not call off the strike, saying the Senate has already lost its credibility among Nigerians over its bogus allowances and perpetual anti-masses stance as opposed to the progressives in the House of Representatives.

The release said: “We are fighting a just cause. Can the Senate members wait for four years of their tenure before their allowances are paid? Can the Senate members seat in the chambers without air conditioners? What role has the Senate played to increase budgetary allocation to education? It is even funny for the Senate President to feign ignorance of the ASUU agreement as the sitting Senate President in 2009.”

Learning How to Convert Heat Directly Into Power: A Thermoelectric Materials Emulator




Discovered in the 19th century, thermoelectric materials have the remarkable property that heating them creates a small electrical current. But enhancing this current to a level compatible with the needs of modern technologies has revealed an extraordinary challenge for scientists of the last decades, despite important theoretical and experimental efforts. Now a novel approach could lead to substantial progress. At ETH Zurich the quantum optics group of Tilman Esslinger has created a key model to better understand the fundamental phenomena — “a thermoelectric material emulator.”


It happened almost by chance: In Zurich group member Jean-Philippe Brantut and his colleagues had just set up a new experiment when visiting professor Antoine Georges from the Collège de France and University of Geneva had a look at the laboratory and was thrilled. “We didn’t really think that in our experiment we could have efficient thermoelectricity,” remembers Jean-Philippe Brantut, “but then he told us, that our setup was extremely interesting, something he and his colleagues Corinna Kollath (University of Bonn) and Charles Grenier (Ecole Polytechnique — CNRS) had been looking for for years.”

Antoine Georges returned the very next day with a bunch of equations to convince the researchers that their experiment was an ideal way to study thermoelectricity. This triggered a fruitful collaboration between theorists in Paris, Bonn and Geneva and experimentalists in Zurich. The results of the international team are now presented in “Science.”

From heat to electricity

The generation of electricity from heat usually involves burning a combustible, which then heats a fluid that brings a mechanical turbine into motion, which eventually produces an electrical current. In thermoelectric materials, the entire cycle that is performed by a heat engine occurs naturally. However, this effect is weak and for the materials known so far, the efficiency of thermoelectric generators is much smaller than that of electrical power plants.

At the moment the technology is mainly used for powering space probes like rover Curiosity exploring planet Mars or for small devices like self-powered sensors. But experts expect a wide range of possible applications in the future. In any engine there is a lot of heat wasted. Car companies are already testing different systems to recover energy from the exhaust gas expecting fuel savings of 3 to 5 %. Other consumer applications could be powering mobile phones or watches by body heat. A highly efficient thermoelectric material would be a major source of renewable energy, since heat is usually wasted by human activities.

At ETH the thermoelectric material emulator sits in a vacuum chamber made out of glass. Enclosed is a gas of Lithium atoms. Using lasers the gas is cooled down to very low temperatures close to absolute zero below minus 273 degree Celsius. Under these conditions the atoms in the gas behave like the electrons in a material. To simulate thermoelectricity the atoms are trapped by a set of laser beams. These create a spatially varying structure in which the atoms move like electrons in a material.

A big surprise

Using atoms trapped by lasers to simulate the behavior of complex materials is a well-tested method in Zurich. For the last ten years the ETH quantum optics group has studied superconductors or magnets, and even devices attached to leads and conducting currents. But the researcher didn’t expect their new experiment to be such a big success. “With simple ingredients we simulate thermoelectricity that is as high in efficiency as in natural materials,” explains Tilman Esslinger, Professor for Quantum Optics. “That was a big surprise.”

Although it is still basic research the experiment may have a stronger impact on materials science than the team thought at the beginning. “Our experiment could serve as a kind of benchmark,” says Jean-Philippe Brantut who will continue with his research founded by the Swiss National Science Foundation. In the next two years the team will try to bring the original experiment forward in order to study more complex systems. But already now the cold atom emulation shines a new light on thermoelectricity: comparison between theory and experiments, which are often hard for natural materials due to their high complexity, can now be precisely performed on the atoms. Even the effects of defects and disorder in materials have been successfully explored with the cold atom emulator.

With these new findings, the fundamental processes underlying thermoelectricity can be studied in a controlled way. This may help the simulation and design of thermoelectric materials in the future, in particular where experiments on natural materials still lack theoretical interpretation.

college student kills herself after her parents banned her from Facebook


A second year college student killed herself after her parents banned her from Facebook left note saying she ‘couldn’t live without the site’


A teenager who killed herself after her parents banned her from Facebook left a note for a devastated family saying she couldn’t live without the site.

Aiswarya Dahiwal, a second year college student from Parbhani, in the Maharashtra state of India, had asked her parents for permission to log on to the site on Wednesday, but they said no.


The teenager then got into an argument with the couple who told her that she should pay more attention to school work, and spend less time on Facebook.

The parents of a 17-year-old girl who killed herself after being banned from Facebook have described their ‘deep shock’ (picture posed by model)





The family also argued about Miss Dahiwal making long mobile phone calls to her friends.

Her body was found on Thursday morning, and police said that she had hanged herself.


A note found in Miss Dahiwal’s bedroom said that she had taken her own life because she was not allowed to go on the social networking site.

Police said that in the note the teenager had said that she couldn’t stay in a home with the restrictions she felt she was being placed under, and that she couldn’t live without Facebook.


In India 92 per cent of high school pupils prefer using the site to talking on a phone (posed by model)

Speaking the Wall Street Journal in India her father Sunil said the family was in ‘deep shock’ and that he ‘never thought she would ever take such a harsh step.’

A case of accidental death has been registered by Indian officials and an investigation is underway.

According to the Wall Street Journal, a recent survey found that nearly 92 percent of India’s high school students prefer to use Facebook rather than make calls to communicate.

The Wall Street Journal also reported that 16,112 people killed themselves in the state last year, making it the state with the second highest suicide rate in the country.

GOODNEWS to those who are blind-->high-tech glasses that makes you see!!!


Legally blind Grade 4 student sees with high-tech glasses



Emma-Rose Gibson can see clearly no more than three centimetres in front of her, but a new device is allowing the nine-year-old Ottawa girl to watch TV.

The legally blind Grade 4 student, who is diagnosed with optic nerve hypoplasia, is one of the first users of the eSight eyewear, a pair of computerized glasses officially launched Tuesday in Toronto.

The device — made by Ottawa-based eSight Corporation — ​ reconfigures images captured by its high-definition camera in a way to optimize a user’s vision.

The processed images are then fed into two LED screens in front of the user’s eyes.

Gibson, who has been using the device since May, said it allows her to participate fully in class and grants her a degree of mobility she didn’t have before.

“When I first heard of it, I was like, ‘Wow, this can actually change my life,”‘ she said. “I went from just seeing nothing to seeing everything in my classroom.”

The president and CEO of eSight said the eyewear is mostly software-based, and can be easily upgraded over the years.

“ESight is mobile, hands-free, and can automatically process near, far and mid-range vision tasks,” Kevin Rankin said.

John Rafferty, the president of the Canadian National Institute for the Blind (CNIB), attended Tuesday’s launch.

“It’s an exciting device that can enable some people to recapture activities they haven’t experienced in decades, like watching their kids play soccer or reading the Sunday morning newspaper,” he said.
Eyewear still relies on user’s sight

But Rafferty said the eyewear — which costs about $10,000 — still relies on the wearer’s sight, and is designed to help those with partial sight, and not the completely blind.

According to CNIB, legally blind is defined as worse than or equal to 20/200 vision with correction — a legally blind person six metres in front of an eye chart sees what a person with normal vision sees at 60 metres.

In Canada, vision worse than 20/50 with correction disqualifies people from obtaining a driver’s license or restricts their driving to daytime only.

“What we’re doing is optimizing that remaining sight,” Rankin said. “A lot of the diseases types we work with, the eye conditions can’t be improved by drugs or surgery.”

Development of the device was made possible with financial support from the Investment Accelerator Fund, which is funded by the Ontario government and provides up to $500,000 in seed funding to Ontario-based technology companies.
