Wireless device makes clean fuel from CO2, water and sunlight

A team of researchers from University of Cambridge have developed a wireless technology that converts sunlight, carbon dioxide and water into a carbon-neutral fuel and requires no electricity.

It is based on an advanced ‘photosheet’ technology that converts sunlight, carbon dioxide and water into oxygen and formic acid which is a storable fuel form. It can be either used directly or can be converted into Hydrogen.

This was published in the ‘Nature Energy’ journal and outlines a novel methodology for the conversion of carbon dioxide into fuel. It aims to achieve artificial photosynthesis by mimicking the ability of plants to convert sunlight into energy. The technology solely relies on photo-catalysts (carbon-dioxide converting cobalt-based catalyst) embedded on a sheet. The sheets are made up of semiconductor powders which can be scaled up to several square metres and can be employed like that of solar cells.

It is a cleaner source compared to others as it shows a higher degree of selectivity and a lesser number of by-products and shows a promise for a clean renewable energy resource with maximum efficiency.

Muslim Jamaat in Thoothukudi demolishes Hindu temple hall, occupies temple land

Residents of Ganesapuram in Thoothukudi district have risen in protest after a Muslim Jamaat demolished a Hindu temple hall and occupied the temple land.

It is alleged that the members of the Jamaat broke the fence of the temple, demolished the temple hall and occupied the temple space.

In one of the video, a woman resident says that the temple hall where rituals and worship were conducted for years by the local Hindus was demolished by the Muslim Jamaat. She says that the villagers have been protesting since the morning asking government officials to take action. However they have been made to run pillar to post between Tahsildar office and police station in an attempt to quell the issue. She also says that the Jamaat members have been surveying and measuring the land wrongly. “The neem tree planted 40-50 years back which people worship is also being usurped by the Jamaat”, she says. She requests all organizations working to preserve Tamil culture to lend support.

In another video, an old lady names a few members of the Jamaat – Peer Mohammad, Sheikh Mohammad – and said that they had come and demolished the temple hall. She says that the police have not taken any action and are failing to register a case. “They haven’t filed a case.. all they are asking us to do is wait, wait, wait.” She says that the villagers won’t budge until action is taken on the Muslim land grabbers.

The issue meanwhile is beginning to get traction on social media.

After returning to school, Greta Thunberg finds a new cause to show her ‘activism’

Greta Thunberg, who shot to fame as a climate ambassador overnight, now has a new cause: stopping the Indian government from conducting the NEET and JEE exams.

She tweeted on Tuesday saying conducting exams during coronavirus pandemic and extreme floods was deeply unfair to students.

While her tweet invited many responses from young men and women across the globe, the climate activist – who has just returned to school after a gap year of creating awareness about the climate emergency – also faced a lot of backlash for her stand.

Students all over the country have been demanding to cancel these two entrance exams highlighting how badly the country has been hit with the pandemic and floods in several states. Several politicians have also supported this demand saying that the current conditions post by coronavirus, as well as the various disastrous conditions in several states, is not conducive to conduct exams.

Meanwhile, the Ministry of Education has maintained that it will conduct exams in September, and responded to the various petitions that were filed, saying ‘life cannot be stopped.’

Meet the 3 year old baker who has baked and delivered 1000 cookies to COVID frontline workers

Mia Villa, a 3-year-old girl from Stillwater, Oklahoma, is thanking those on the frontlines fighting COVID-19 by delivering homemade cookies. She has been baking ever since she was 18 months old, and has become a sensation after she baked and delivered over 1000 cookies to the frontline workers of the COVID-19 pandemic.

Named Mia’s Cookie Jar, this venture was started by Mia and her mother Devin, who make deliveries a few times a week to police stations, hospitals, fire stations, and other places. Each batch that they deliver is baked fresh that morning and gets boxed up, with a picture from Mia. At every place they’ve delivered cookies to, Mia has gotten to learn a bit more about what each first-responder does, from fighting fires to healing wounds.

“With the pandemic and everything being shut down, [there’s] a lot of pressure on the first-responders,” Devin said, “I use this is a way to teach her about the people that we are most grateful for and she can do something she loves.” “She does it all by herself,” Devin added. But Mia’s younger brother Gino is her quality assurance team, taste-testing cookies whenever he’s needed.

She is the great-granddaughter of the former mayor of Amsterdam, and has become viral on Facebook and Instagram, gaining what she calls “cookie followers”. She regularly bakes and posts recipes about the project.

After Chief of Defence Staff General Bipin Rawat, yesterday (July 24) had said, the military option to push back the Chinese transgressors is still on the table, Indian forces have been equipped with shoulder-fired air defence missiles in Ladakh heights, reported by Times of India.

China is not willing to deescalate and Chinese helicopters are now flying very close to the Line of Actual Control (LAC) in Eastern Ladakh.

“Indian troops armed with the Russian-origin Igla air defence system have been deployed on the crucial heights along the border to take care of any enemy aircraft trying to violate the Indian air space there,” sources told ANI.

The Russian-origin Igla air defence systems are capable of shooting down enemy fighter jets or helicopters. This is a preventive measure that has never been previously exercised by the Indian military which shows hostilities have still not ceased.

India has deployed radars and surface to air missile systems to keep track of the enemy air movement after Indian forces had observed that a number of Chinese choppers had tried to come inside Indian territory.

India has also deployed its frontline fighters, the Su-30MKI is keeping a close eye on the Hotan, Gar Gunsa, Kashghar, Hopping, Dkonka Dzong, Linzhi and Pangat airbases of the PLAAF in the Xinjiang and Tibet region that has seen a lot of activity in the last week or so.

Rohingyas mark third anniversary of exodus to Bangladesh with silent protest

The Rohingya Muslim refugees marked the third anniversary of their exodus to Bangladesh with a silent protest. This exodus, as a result of clashes between Myanmar army and Rohingya insurgents, set off a huge movement of Rohingya Muslims as refugees into Bangladesh.

Ideally, they would have gathered in a mass gathering to commemorate this day. Owing to the novel coronavirus pandemic, they said that they had decided against it and marked what they call the Remembrance Day with a silent protest. Since 2018, they have been observing August 25 as “Rohingya Genocide Remembrance Day” as on the same day in 2017, Myanmar army began a brutal crackdown against Rohingya insurgents, forcing more than 750,000 people to flee to neighbouring Bangladesh.

More than 1.2 million Rohingya have been living in makeshift settlements in Bangladesh’s southeastern district of Cox’s Bazar for years. Authorities say 88 cases of the virus have been found in the camps and six people have died. The Myanmar military crackdown that followed forced 730,000 Rohingya to flee to Bangladesh, joining more than 200,000 already there.

Meanwhile, the United Nations said the crackdown by the Myanmar military was carried out with genocidal intent. Myanmar denies genocide, saying its forces were engaged in a legitimate campaign against the Rohingya insurgents, and it was the insurgents who were responsible for most of the violence, including the torching of villages.
