NATIONAL / KARNATAKA: SCIENCE & TECHNOLOGY: IISc Researchers Develop Novel Thermal Desalination System

These systems work by heating saltwater, then condensing the resulting vapour to obtain freshwater and can be a possible solution to increase the availability of clean, potable water.

As a possible solution to increase the availability of clean, potable water, Indian Institute of Science (IISc) researchers have developed a novel thermal desalination system which can work using solar energy.

The most common methods for desalination are membrane-based reverse osmosis and thermal desalination. However, both consume a lot of energy.

According to IISc, thermal desalination systems work by heating saltwater and then condensing the resulting vapour to obtain freshwater.

Environment-friendly

“But the energy required for evaporation is usually obtained from either electricity or combustion of fossil fuels. An environmental-friendly alternative is using solar stills in which solar energy is employed to evaporate saltwater in large reservoirs and the vapour that condenses on a transparent roof is collected. However, during condensation, a thin layer of water forms on the roof, reducing the amount of solar energy that can penetrate the reservoir and therefore, the system’s efficiency,” said IISc.

“As an alternative to such solar stills, the IISc team has developed a novel design for a solar-powered desalination unit that is more energy-efficient, cost-effective and portable, making it convenient to set up in areas with limited access to continuous electricity,” said Susmita Dash, Assistant Professor in the Department of Mechanical Engineering and corresponding author of the study which has been published in Desalination.

The setup, designed by Dash and her PhD student Nabajit Deka, comprises a reservoir of saline water, an evaporator, and a condenser enclosed within an insulating chamber to avoid heat losses to the ambient air. Their system works by using solar thermal energy to evaporate a small volume of water imbibed or “wicked” into the evaporator, which has a textured surface. The wicking of liquid into the evaporator takes advantage of the capillary effect of microscale textures.

“This effect allows liquids to be drawn into narrow spaces of a porous material, much like water being absorbed by a sponge. Utilising this approach, instead of heating the entire liquid volume in the reservoir, results in a significant improvement in the system’s energy efficiency,” says Dash.

Works for groundwater too

Apart from seawater, the system can also work with groundwater containing dissolved salts as well as brackish water. It can be adjusted to align with the shifting positions of the sun during the day.

IISc said that the researchers are currently working on scaling up the system and improving its durability, and increasing the volume of drinking water produced, so that it can be deployed for domestic and commercial use.

KARNATAKA: RURAL INNOVATION / AGRICULTURE : Siddapur Farmer Vidyadhar Bhat Designs Wonder Modified Vehicle that carries 300 kilos of load

 Though the vehicle looks like a scooter, it does work of an autorickshaw. It is also quite useful for the farmers.

A farmer who was tired of carrying things on his shoulders has designed this vehicle, which is developed from his old TVS moped.

The farmer who has designed this unique vehicle is none other than Vidhyadhar Bhat, a resident of Unchalli of Siddapur taluk of the district.

An old TVS moped that was lying in Vidhyadhar Bhat’s house was getting rusted. So Bhat thought of using it as a cart vehicle and a sketch was made in cooperation with local engineer Prashanth. Later, they developed a three-wheeler vehicle having tyres of a scooty and an auto.

The vehicle has the engine of CT 100 and has brakes of an Omni vehicle. A  container that is fitted on the backside can carry up to 300 kilos of load. The vehicle has a fan and an intercooler as well.

The vehicle gives a mileage of 20 km to a litre if the load is full. Otherwise it can give up to 30 to 35 kilometers to a litre. On the whole, this wonder vehicle is farmer-friendly. This vehicle allows the farmer to finish off his work without depending much on labourers for farm-related work.

GLOBAL: ARTS & CULTURE: Deepika Padukone Appears on Cover of TIME Magazine

The influential American magazine described Padukone as a ‘global star’ bringing ‘the world to Bollywood’.

Bollywood star Deepika Padukone has been featured on the latest cover of TIME magazine. The iconic American magazine described Padukone as a ‘global star’ bringing ‘the world to Bollywood’. It had previously named Padukone among its list of 100 most influential people in the world in 2018.

On Instagram, Padukone shared pictures and videos from the cover shoot. The Pathaan and Padmaavat actor is seen clad in an oversized light brown suit with no footwear.

Padukone’s international profile has risen over the years. In 2017, she made her Hollywood debut opposite Vin Diesel in XXX: Return of Xander Cage. She unveiled the 2022 FIFA World Cup trophy in Qatar and was a jury member at Cannes.

Earlier this year, Padukone was seen presenting at the 95th Academy Awards, where ‘Naatu Naatu’ won Best Original Song.

In the accompanying profile in TIME magazine, Padukone was asked about the frequent political controversies that have marked her career. These include protests against her 2018 period drama film Padmaavat, the reactions to her appearance at a student vigil in Jawaharlal Nehru University (JNU) in 2020, and the backlash against her “saffron” outfit in a song in Pathaan.

“I don’t know if I’m supposed to feel something about it,” Deepika was quoted as saying about the political backlash. “But the truth is, I don’t feel anything about it.”

Tech blog winner’s programme to identify plants may prove a game changer in Ayurvedic pharma sector

Dr K V N Rajesh, a certified trainer on the Azure platform and holds a doctorate in deep learning, says that his model has achieved 95 per cent accuracy in identifying images of leaves available on the internet, based on the plant “flavia”.

With Ayurveda making rapid strides in the Indian pharmaceutical industry, the winning entry by Dr K V N Rajesh in the first phase of the ongoing Microsoft Azure Blogathon contest may prove to bring dynamic change rooted in this direction. The programme, written in the Python programming language and using Microsoft’s Azure cloud platform, is intended to help distinguish between different types of plants.

Rajesh, who is a certified trainer on the Azure platform and holds a doctorate in deep learning, said that there are many species of plants and identifying them based on the leaves is a task that needs to be solved. “Many companies making Ayurvedic products use leaves in their products, and identifying the exact species is a crucial problem,” he says. He also explains that the same concept can be applied in the agricultural field, specifically with regard to dealing with plant diseases and pests.

“Plant leaves have attributes such as colour, shape, texture etc. based on which you can identify them. I developed an architecture based on a deep learning model, a subset of artificial intelligence which will automatically grasp these attributes. The model which is generated is trained with images of leaves. When the model training is complete, it is validated based on the data set of the leaves,” he points out.

The second phase of testing involves testing the accuracy of the model. According to Rajesh, his model has achieved 95 per cent accuracy in identifying images of leaves available on the internet, based on the plant “flavia”.

“Thirty per cent of the images were used to train the model, and the rest were used to test it,” he says. He intends to take the programme further by incorporating it into a mobile application.

Speaking to The Hindu, Dr. Mathai said, “For 18 years, both the King and Queen Consort have been consulting me as a holistic consultant. The Queen Consort has visited SOUKYA eight times, and the King came once. They really enjoyed being in India at our centre for treatment.”

“Being a part of the coronation is the proudest moment of my life. I regularly meet the King and the Queen Consort in London. Other than medical consultation, the King has some interest in holistic medicine. The King and I also have a common interest in organic farming and climate change,” he said.
