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)

Expanding its premium portfolio, HP Inc. on Tuesday launched the HP ENVY x360 convertible powered by AMD Ryzen processor for the millennials in India.

HP ENVY x360 with AMD Ryzen R3 processor would be available from November at a starting price of Rs 60,990.

The variant with 256GB storage will cost Rs 74,990. The company is also offering a bundled HP Active Pen that works with Windows Ink.

“We have about 30 per cent share in the premium segment and this is growing much faster than the lower-priced segment. We’re expecting to increase our share and get rapid uptake from the customers,” Vickram Bedi, Senior Director, Personal Systems, HP Inc. India, told IANS here.

“At HP, we believe in insights-driven innovation that enables us to deliver the PC experiences that users want. The HP Envy x360 is a combination of sleek design, optimum performance and quality at an affordable cost,” he added.

The convertible features the all new HP Command Center which lets users optimise system performance, fan noise and temperature with its CoolSense technology.

The device supports Gigabit Wi-Fi speeds, to provide fast Internet connections for demanding streaming apps for movies, music and gaming.

The unique design of the laptop draws inspiration from hand-crafted pieces that feature the Damascus pattern — a high precision technique used in manufacturing specialty knives, known to be tough and durable, the company added.

AMD Ryzen processor gives performance up to 12.5 hours of battery life, charging from zero per cent battery life to 50 per cent on 45 minutes charge with HP Fast Charge technology, the company claimed.

The Corning Gorilla Glass NBT touchscreen gives highly intuitive reaction, with HP Active Pen for a seamless and natural work experience.

The device is available in Dark Ash Silver colour with an angular Damascus pattern, thin bezels and edge-to-edge backlit keyboard.
