A 14-year-old boy in Gujarat has signed an agreement worth Rs.5 crore to explore the possibility of commercial production of a drone created by him which can help in detecting and defusing landmines in war fields.
Harshwardhan Zala, who is studying in Class 10, started work on the prototype of the landmine-detecting drone last year after reading in newspapers about high army casualties due to landmines.
“I first created a land mine detecting robot but realised that since the weight is heavy it would trigger a blast and damage it so I thought of creating a drone which will be at a safe distance while detecting the mines,” said Harshwardhan, who signed the Memorandum of Understanding (MoU) at the recently-concluding Vibrant Gujarat summit in Ahmedabad.
The state government had even part financed his final prototype which cost him around Rs. 5 lakhs. Now the government experts will explore the possibility of its commercial production.
Explaining the concept, Harshwardhan said that once the mine was detected by the drone through an infrared sensor, a 50 gram detonator will complete the task of defusing it
Harshwardhan, whose father is an accountant, has set up his own company – Aerobatics 7 – and plans to create more such gadgets. A student of Sarvoday Vidhyamandi, he says he has been interested in science and innovation for several years now.

Aishwarya Trivedi, 23, who graduated in architecture from a college in Vadodara, is now included in the World Genius Directory (2016) from the Asia region with an IQ recorded at 150.
Aishwarya is now doing her further studies on Construction Project Management at the New York University in the USA. The eldest child of an architect mother and ex-naval father, she is among the Who’s Who of the high IQ world.
She falls in the range of 2% of the world’s population with very high intelligence. She first joined the hi-IQ community Mensa India, then went a step ahead and was included in the World Genius Directory. She feels it is an achievement that her views were accepted by geniuses.

India has successfully tested its scramjet or air breathing engine, with the launch of a rocket.
An official from the Indian Space Research Organisation (Isro) said two scramjet engines were tested during the flight.
He said the two air breathing engines were hugging the rocket on its sides and when the rocket reaches a height of 11 km, the scramjet will start breathing air.
The scramjet engine, used only during the atmospheric phase of the rocket’s flight, will help bring down the launch cost by reducing the amount of oxidizer to be carried with the fuel.
The test flight was the maiden short duration experimental test of Isro’s scramjet engine with a hypersonic flight in Mach-6.
Isro said some of the tech challenges handled during the development of the scramjet engine include design and development of hypersonic engine air intake, development of materials withstanding very high temperatures, proper thermal management and ground testing.
India is the fourth country to demonstrate the flight testing of the Scramjet engine.

Indian scientists from the Council of Scientific and Industrial Research (CISR) laboratory in Kolkata have designed a ‘solar tree’ that they hope will help overcome a key challenge the country faces in the generation of solar power.
With photovoltaic panels placed at different levels on branches made of steel ‘solar trees’ could reduce the amount of land needed to develop solar parks.
Daljit Singh Bedi, chief scientist at the CISR in Delhi said it takes about four-square meters of space to produce energy, which would otherwise require 400 sq meters of space.
Scientists estimate the energy generated by a solar tree would be enough to light up five homes, and the tree would make it easier to increase solar power generation to light up homes and streets in cities and 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.
India’s pledge to reduce its carbon emissions, that was made at the UN Conference on Climate Change in Paris last year, relies heavily on increasing the generation of solar energy. To achieve this India has set an ambitious target of generating 40 percent of its total capacity from renewables by 2030 and also reducing its reliance on polluting coal-based thermal energy.
While the falling cost of photovoltaic panels has made solar power more viable and investment has been flowing into the growing sector, worries remain about acquiring large tracts of land to set up solar parks.
Amit Kumar at the Energy and Resources Institute, Delhi, says solar trees could provide a sustainable option but innovations on solar power have so far not made much headway.

“Women of Worth’ awardee Lalita Prasida Sripada Srisai a grade XI student from Damanjodi in Koraput district in Odisha, won the Community Impact Award at the Google Science Fair 2015 held in California.
She developed a cheap way of cleaning waste water, that uses waste corncobs as a key ingredient. The purifier cleans waste water by flowing through different layers of corncobs, which is a cost-effective simple technique that immobilizes contaminants in ponds, reservoirs and water tanks. She was awarded $10,000 as prize money and is being mentored by Google to build the project.
In her experiment Prasida found that waste corncobs are able to absorb contaminants like salt oxides, detergent, suspended particles, coloured dyes, oil, grease and even some heavy metals.
Prasida said she likes to visit nearby villages and observe their lifestyle that revolves around cultivating varieties of crops, from which she developed an interest to focus on science and develop something new related to agriculture.
