Scientists Develop All-Season Smart-Roof Coating

Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer without consuming natural gas or electricity.

Research findings point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings.

“Our all-season roof coating automatically switches from keeping you cool to warm, depending on outdoor air temperature.


This is energy-free, emission-free air conditioning and heating, all in one device,” said Junqiao Wu, a faculty scientist in Berkeley Lab’s Materials Sciences Division and a UC Berkeley professor of materials science and engineering who led the study.

Today’s cool roof systems, such as reflective coatings, membranes, shingles, or tiles, have light-colored or darker “cool-colored” surfaces that cool homes by reflecting sunlight.

These systems also emit some of the absorbed solar heat as thermal-infrared radiation; in this natural process known as radiative cooling, thermal-infrared light is radiated away from the surface.

Elon Musk Says His Satellites Not Taking Too Much Room In Space

0

Elon Musk has rejected claims that his Starlink satellite internet project is taking up too much room in space.

“Tens of billions” of satellites can be accommodated in orbits close to Earth, he told the Financial Times.

His comments come after a claim by the head of the European Space Agency (ESA) that Musk was “making the rules” for the emerging commercial space industry.

This week, China complained that its space station was forced to avoid collisions with Starlink satellites.

“Space is just extremely enormous, and satellites are very tiny,” Mr Musk said in the interview.

Mr Musk pushed back at suggestions that his Starlink Internet Services project was effectively obstructing the entry of competitors to the satellite industry, saying that there is ample room in the Earth’s orbit for satellites.

“This is not some situation where we’re effectively blocking others in any way. We’ve not blocked anyone from doing anything, nor do we expect to,” he said.

“A couple of thousand satellites is nothing. It’s like, hey, here’s a couple of thousand of cars on Earth, it’s nothing,” he added.

Lagos To Host Del York, Storyland Studios To Develop Ultra-Modern Film City

0

The African entertainment industry is about to receive a significant facelift in its fortunes and outlook, a signal that the great cultural renaissance that has long been the promise of the continent is finally about to be realised.

The Del York International Group has signed on with one of the biggest movie studios and theme park design developers in the world to partner it to develop a major film city project in Lagos.

According to reports from several international news outlets, Del York and Storyland Studios signed the deal to develop the project in a location called Epe in partnership with the Lagos State Government.

Lagos is undisputedly Africa’s business capital with an estimated 20 million people living in the city, the siting of the new film city will most likely dramatically improve the economic potential of the state if not tourism throughout the region.

The film city project is being described as a place where creatives can live, work, and learn and is proposed as an all-in-one facility that will commingle the best in leisure and theme park facilities with that of film making and industry capacity building.

The promoters have included multiple sound studios, backlot sets, water tanks, workshops, and production offices alongside a theme park setting that includes rides, tourist attractions, movie museums, and a walk of fame.

The President of Del York International Group, Linus Idahosa who is also the founder of the Del-York Creative Academy, said, “The continent’s burgeoning community of creatives have long been inspired through the magic of film and television, spiriting themselves into worlds they never thought possible but curtailed by their immediate circumstances.

With this agreement in place, we can finally realise that purpose-designed infrastructure that will match the dreams and most expansive imaginations of creatives on the African continent”.

The Founder and Chief Creative Officer of Storyland Studios Mel McGowan was quoted as saying “We’re excited to be part of the further development of Nigeria’s incredibly prolific and rapidly-growing film industry.

The Lagos film city concept is a cultural, creative ecosystem that will be a catalyst not only for the country of Nigeria but for Africa”.

Construction of the multimillion-dollar facility is scheduled to start in early 2022.

Egypt Parliament Resumes General Sessions To Discuss Questions On Education

0

Egypt’s House of Representatives resumed its general sessions to discuss a number of questions addressed to the country’s Minister of Education, Tarek Shawqi.

The House approved amending three laws that regulate the Renewable Energy Authority, universities, and the Academy of Arts.

According to the chairman of the parliament’s energy committee, Hossam Awadallah, the first law states that the Hydroelectric Stations Authority will be phased out and replaced by the Renewable Energy Authority.

The House also approved amending the law regulating universities, doubling the financial sum granted to professors when they reach retirement age and become emeritus professors.

Chairman of the House’s Education Committee, Sami Hashem, said the objective of the amendment is to legally allow highly-experienced university professors to stay in service as emeritus professors after they reach the retirement age of 60.

A Member of Parliament, Amira Abu Shoka, said the amended law opens the door for Egyptian universities to seek the service of highly-experienced and gifted professors who reach retirement age.

Parliament also approved a third law regulating the Academy of Arts.

Chairwoman of the House’s Culture and Media Committee, Doreya Sharafeddin, said the law regulating the performance of the Academy of Arts was amended to open the door for members of the academy’s teaching board who reach retirement age to stay in service and get a financial bonus plus the pension salary.

Parliament speaker Hanafi Gibali said the three laws will be put up for a final vote in a later session.

Balearic Islands Opens Solar PV Park To Local Participation

0

The Santa Eulalia Park in the municipality of Santa Margalida in the island’s northeast is proposed to comprise 9.626MWp of solar PV on a 5ha site, split into two halves – Santa Eulalia I and Santa Eulalia II – with different ownerships and different and independent connections to the medium voltage grid.

The proposed offer for public participation is €809,360 (US$917,000) to provide a 40% share, with 20% of the economic return to remain in the Balearic Islands.

Investment priority starts with residents in the neighbourhood of Santa Margalida for 15 days.

At the end of that period, the radius is further extended in 15-day periods for the unsold amount first to the neighbouring municipalities, then to the other Balearic Islands and finally to the whole of Spain.

The Balearic Islands are an archipelago off eastern Spain, in the Mediterranean. Mallorca (Majorca), the largest island, is known for its beaches, scenic coastline and the Serra de Tramuntana mountains to the north. Palma, the capital city, is known for its Gothic cathedral with an altar canopy by modern architect Antoni Gaudí, and Almudaina, a Moorish royal palace.

“Local participation is essential in the new distributed energy model that is coming as we are moving away from having one or two thermal power plants in the territory to having many renewable installations,” said Pep Malagrava, director-general of Energy and Climate Change of the Balearic Islands government.

“Moreover, this local participation links the project with the territory and its citizens. That is why the path we are embarking on with this park is so important because it allows the citizens of the municipality of Santa Margalida to invest in a renewable generation plant and obtain benefits from this investment, returning them as a priority to the territory where the park is installed”.

Public participation in renewable generation facilities was introduced in Balearic Island Law 10/2019 on climate change and the energy transition with the requirement of a minimum 20% participation in facilities with a capacity of 5MW and greater.

The Santa Eulalia solar park will be developed by the local renewable company G-Ener and German solar specialist Enerparc.

Funding for the park is via the Spanish renewable energy crowdfunding platform, Fundeen. The minimum investment required is €500 and the profitability is estimated at 6.5% over seven years.

Chemical Giant To Dump More Toxic Waste In South African Ocean

0

United Phosphorus Ltd (UPL) is planning to dump even more poisonous pesticides into the sea in an apparent bid to save money on land-based disposal costs barely a month after several Durban beaches were re-opened to tourists and locals.

Several of the city’s most popular swimming beaches were closed for nearly four months as a safety precaution after a torrent of pesticides and other agro-chemicals poured into the sea in the wake of the July, 2021 arson attack on the UPL chemicals warehouse in Cornubia, north of Durban.

Residents of a shack settlement in Cornubia continue to suffer from ill-health after the toxic chemical spill.

South African environmental activists, as well as residents of Cornubia, have slammed the Mumbai-based agrochemical company for its conduct before and after the chemical spill that has been described as one of the biggest disasters in the country in the past “30 to 40 years”.

The UPL warehouse was set ablaze on July 12, 2021 and then exploded, causing extremely hazardous and toxic agrochemicals to spread to the beaches, rivers, soil and air to the north of Durban for several days.

Contaminated beaches were only partially reopened for recreational purposes on 2 November to ensure the safety of beachgoers.

Mauritius Oil Spill: Ship Captain, Officer Get Jail Terms

0

Captain Sunil Kumar Nandeshwar has admitted he was drinking alcohol as cargo ship Wakashio ran aground in July 2020, spilling more than 1,000 tons of fuel into the Indian Ocean near the coast of Mauritius.

The oil leak resulted in the Indian Ocean archipelago’s worst-ever environmental disaster, that saw the captain and officer handed 20-month prison sentences.

The bulk carrier MV Wakashio ran aground on July 25, 2020, crashing into a reef.

The ship was carrying over 3,900 tons of fuel oil along with 200 tons of diesel. Nearly 1,000 tons of this cargo leaked into the ocean after the Japanese-owned vessel’s hull cracked on August 6, 2020.

The oil spill’s long-term impacts on the island nation’s fragile ecosystems will take years to fully comprehend, Deutsche Welle reported at the time.

Mauritius had asked Japan to pay close to 3.6 billion yen (€28.5 billion, U.S.$34 million) in order to support local fishermen whose livelihoods were adversely impacted by the oil leak.

Investment in childcare could generate 17 million jobs in Nigeria – Report

0

Investments in free universal childcare could generate 17 million jobs in Nigeria, especially for women, reducing the gender gap in employment by up to seven percentage points.

This was disclosed in a report titled ‘Green Jobs for Women in Africa’, which was based on a study by the African Natural Resources Centre of the African Development Bank and the United Nations Women Regional Office for West and Central Africa.

The report emphasised the need to invest in universal childcare in Africa, which would significantly benefit the continent.

The report read in part, “UN Women estimates that investments to achieve free universal childcare could generate 0.9 million jobs in Senegal, 1.2 million in Côte d’Ivoire, 17 million in Nigeria, 1.4 million in Rwanda, and 7 million in the United Republic of Tanzania. 

“The study also shows that the majority of jobs would be for women, reducing the gender gap in employment by up to 7 percentage points in some countries.”

The report also affirmed that Africa is suffering from the effects of the COVID-19 pandemic, which has deteriorated economies and impoverished more people.

“Africa is shouldering the effects of an unprecedented pandemic. The resulting economic crisis has worsened social conditions and increased economic vulnerabilities, and lockdown measures and social distancing have impeded supply and demand, endangering the livelihoods of countless people.”

It added, “The crisis has affected all sectors, from transport to retail and service sectors to tourism, with large disruptions in supply chains and production and extensive job losses. According to African Economic Outlook 2021, gross domestic product contracted 2.1 per cent in 2020. The AfDB estimates that, without adequate support, about 39 million more Africans – the majority of them women – could fall into extreme poverty in 2021.”

It then stressed the need for gender-responsive green growth strategies that would create jobs and benefit the economy of each country in Africa.

The report further read in part, “post-COVID-19 recovery policies in the African continent need to build on gender-responsive green growth strategies that create new green jobs and transform conventional jobs into green jobs. Well-designed green projects can generate more employment and deliver higher short-term returns than conventional fiscal stimulus. Green transformation is expected to create 24 million jobs globally in the next 20 years.

“The Global Commission on Adaptation calculates that every dollar invested in building climate resilience could result in between $2 and $10 in net economic benefit. Identifying opportunities early on and facilitating women’s access to them can reduce gender gaps as part of the post-COVID-19 recovery.”

University Researchers Get N36m Grant to Investigate Kidney Cases

0

A team of researchers at the Federal University, Duste, have received a N36 million research grant from the Tertiary Education Trust Fund’s National Research Fund  to investigate rampant cases of kidney diseases at Hadejia Valley, an area between Kano and Yobe State.

Hadejia Valley stretches from Zakirai in Kano State to Nguru and Gashua in Yobe. It has the highest rate of kidney diseases in Nigeria.

The university’s Chief Information Officer, Abdullahi Yahaya, stated on Tuesday, December, 28, 2021, in Dutse that the National Research Fund gave the grant through the TETFund.

Yahaya stated that the team would be led by Dr. Muhammad Auyo, the Head of the Department of Biological Sciences at the university.

“The lead researcher picked interest in this research area after losing six friends and family members to kidney failure in Hadejia.

“According to Dr. Auyo, the title of the research is: “Rampant kidney diseases in Hadejia Valley, Yobe and Kano States: The Study of Environmental Toxins and Gene Polymorphism,’’ Yahaya added.

He stated also that Auyo wants to find out whether there is the prevalence of a gene called metallothionein, which exposes the people of Hadejia Valley to kidney diseases.

The research also wants to discover the toxins present in the Hadejia Valley in the last 30 years, as a result of the use of pesticides and herbicides, which may have changed the ecosystem.

These chemicals, according to the lead researcher may have affected the food chain, especially crops, water, and fish, and may have been responsible for the high prevalence of kidney diseases in the area.

Yahaya quoted Auyo as saying that the research team will take soil, water, vegetables, cereals, fruits, fishes and meat samples every month for 20 months to search for the presence of heavy metals.

The 16-member multidisciplinary research team is divided into Medical, Environmental, Genetic, and DNA sequencing teams.

Yahaya stated that the research is for two years and is expected to come up with recommendations.
