KARNATAKA: SPACE TECHNOLOGY: Government’s Visvesvaraya Industrial and Technological Museum (VTU) in Bengaluru Exhibits full-scale replica of Mars Rover Opportunity

The Mars Rover Opportunity model, which was kept as an exhibit at the Visvesvaraya Industrial and Technological Museum, was inaugurated on Thursday.

If you are curious to know how the Mars Rover Opportunity of US space agency NASA, which traversed through the barren land of the red planet and revealed many secrets about it, then head straight to the Space Technology gallery of the Visvesvaraya Industrial and Technological Museum (VITM) here.

The Mars Rover Opportunity model, which was built by the students of Cornell University and kept as exhibit at the VITM, was inaugurated by M Sankaran, Director, UR Rao Satellite Centre of Indian Space Research Organisation on Thursday.

The model was initially on display at the Smithsonian’s Air and Space Museum in Dulles, Virginia, in US, and later exhibited in the US Pavelion during the 2020 World Expo in Dubai.

The replica was then received by the American Centre in the US Consulate in Chennai where it was on display from November 2022 to March 2023 before landing at the VITM.

US Under Secretary of Commerce for International Trade Marisa Lago said, “As the United States and India forge even closer cooperation across critical sectors, space provides yet another example of our partnership, with today’s dedication ceremony serving as a symbol of our mutual commitment.”

US Consul General in Chennai Judith Ravin said the arrival of the full-scale replica of Mars Rover Opportunity in India symbolised the longstanding space technology cooperation between India and the United States.

India is an important partner to the United States in space exploration. Initiated in 2005, the United States and India Civil Space Joint Working Group is the venue for a productive exchange of views and discussion on new and expanded areas for civil space cooperation, she pointed out.

According to Ravin, the civil space dialogue between United States and India is framed around four working groups: Earth sciences, space science and exploration, heliophysics, and human space flight.

“The cooperation between our two countries shows that the technologies developed in support of space exploration have real-world applications that affect all of us, from advancements in telecommunications and satellite navigation to agricultural monitoring and weather forecasting,” she said.

The Mars Rover Opportunity was operated on the red planet from 2004 to 2018. It sent thousands of pictures to its control station.

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.

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.
