Indian Researchers develop Solar Tree that will require less space

Indian researchers at Council of Scientific and Industrial Research (CSIR), New Delhi develop a new technique that will require a less lot land


Indian scientists have designed a “solar tree” that they hope will help overcome one of the key challenges the country faces in the generation of solar power.

With photovoltaic panels placed at different levels on branches made of steel, “solar trees” could dramatically reduce the amount of land needed to develop solar parks.

“It takes about four-square meters of space to produce energy which otherwise would have required 400 square meters of space. So almost 100 times the space is saved, which as you know is very valuable,” said Daljit Singh Bedi, chief scientist at the Council of Scientific and Industrial Research (CSIR) in New Delhi, whose laboratory in Kolkata developed the tree.

A scarce resource in India, acquisition of land to develop roads, factories and other infrastructure is a sensitive issue that has led to frequent and sometimes violent protests from displaced people.

Scientists estimate the energy generated by a solar tree would be sufficient to light up five homes. They say the space-saving tree would not only make it easier to increase solar power generation to light up homes and streets in cities, but also in rural areas where farmers are unwilling to give up large tracts of land for solar panel installations.

The solar tree will also harness more energy compared to rooftop panels. “This design, it facilitates placement of solar panels in a way that they are exposed more towards sun and that way they are able to harness 10 to 15 per cent more energy, which is more or less equivalent to one hour more than the conventional format,” said Bedi.

India’s pledge to reduce its carbon emissions relies heavily on increasing the generation of solar energy. The world’s third largest emitter of greenhouse gases, India pledged at the United Nations Conference on Climate Change in Paris last year to slow the rate at which it emits greenhouse gases by one third over 2005 levels by 2030.

To achieve this, India has set an ambitious target of generating 40 percent of its total capacity from renewables by 2030 and reducing its reliance on polluting coal-based thermal energy. In the sun-drenched country, the main focus will be on solar power.

While the falling cost of photovoltaic panels in recent years has made solar power much more viable, and investment has been flowing into the growing sector, worries remain about acquiring large tracts of land to set up solar parks.

“It takes quite a bit of time which results in cost escalation and all those things,” said Amit Kumar at the Energy and Resources Institute, a research institute in New Delhi.

But will solar trees provide a sustainable option? Kumar cautions that innovations that aim at concentration of solar power so far have not made much headway.

“Unless we put those [trees] on a large scale, [only] then will we be able to get that answer,” he said.

However Indian officials like Bedi are optimistic.

“When we talk about plantation of trees, we would now talk about plantation of solar trees,” he said. (VOA)

Twitter India steps in to bridge blood donation gap

Twitter said it will also amplify the real-time communication efforts of the handle with verification, promotion on Twitter, and use Twitter Lite to connect the helpline with people across the entire country

  • Twitter starts a new initiative #BloodMatters
  • This initiative is to create more awareness blood donation and its need in India
  • The step is being applauded and supported by the government as well

Aiming to create more awareness and bridge the demand-supply gap for blood units in India, Twitter India on Tuesday launched a new social initiative called #BloodMatters.

According to a report by the World Health Organisation, only nine million blood units are available annually in India, against a demand of 12 million units. Blood Donors India (@BloodDonorsIN), a voluntary blood donation helpline on Twitter, is the first partner for the Twitter initiative. Through this initiative, Twitter said it seeks to work with more blood donation helplines like @BloodDonorsIN, blood banks, and health institutions across the country to connect and reach a larger audience.

Twitter has launched three types of APIs to facilitate this.
This step will help bridge the blood donation gap in India.

“The platform aims to scale up the volume of blood donation conversation in India, the number of donors, and work with partners that can ensure safe, screened blood can reach those in need in time across India,” Twitter India said in a statement.

With this initiative, people can request for blood donation simply with a tweet to @BloodDonorsIN with their location hashtag, blood type, mobile contact and Twitter handle. People interested to help can follow @BloodDonorsIN and respond or retweet requests for help.

Responding to the initiative in a tweet, Union Health Minister J.P. Nadda said: “I am happy to see Twitter take up this cause to strengthen the overall health and well-being of the country with the #BloodMatters initiative. This will play a powerful role in mobilising resources and strengthening the blood donation drive in India.”

With the new initiative, launched ahead of its 12th birth anniversary on Wednesday, Twitter is expanding the reach of the @BloodDonorsIN helpline through Twitter Lite, which provides more data-friendly access to real-time information exchange on blood donations across India.

Twitter will be supporting the implementation of an automated response solution to scale the operations of @BloodDonorsIN, currently run by a group of volunteers.

Twitter said it will also amplify the real-time communication efforts of the handle with verification, promotion on Twitter, and use Twitter Lite to connect the helpline with people across the entire country, from the metros to rural India.

“Giving back has been a priority for Twitter since its inception and we believe the open exchange of information can be a compelling force for good in the world. #BloodMatters is a step in that direction,” Mahima Kaul, Head Public Policy, Twitter India, said in a statement.

“We are humbled to kickstart the initiative with @BloodDonorsIN, a handle that symbolises our mission of positively impacting the world by harnessing the real-time power of Twitter and hope to make a larger impact by extending its reach through Twitter Lite,” Kaul added. IANS
