New Delhi: IITians have always made their mark with their innovations, here are three devices developed by them that have brought about a change in the society.

Eco Frost: In a bid to curb wastage of agriculture yield in India, three IIT Kharagpur engineers developed a cold-storage powered by solar power and helped farmers to save their produce from getting rotten. The trio of mechanical engineering students Vivek Pandey, Prateek Singhal and Devendra Gupta scripted history and brought in a major change with their micro cold storage system which operates at near zero cost.

With the growing demand of cold storages and only the big farmers having access to the available facilities, Eco-frost changed the fate of millions of farmers. Especially, designed for the rural segment, the innovation helped the farmers to store their harvest and get a good bargain. The solar-powered cold storage led to an increase of 40 per cent in the profits of the farmers.

The young achievers claimed that there is no running cost and works the year round on sustainable technology. Eco-Frost also boasts of a power backup of over 36 hours during inclement weather and has a capacity of five metric tons.

The idea was incubated in 2013, and the team plans to manufacture around 20,000 cold storages in the next five years. The price of one unit will be around Rs 5-6 lakhs.

Guardian: A clear cut winning project, the safety device ‘Guardian’ addresses the problem of women security. What made it stand apart was its provision to use any type of

communication systems like the internet, SMS, or Near Field Communication. Moreover, the device can be worn in the form of jewellery and is convenient to carry.

Developed by IIT Delhi students, Guardian alerts loved ones when a person is in distress.

Alcohol Sensing Helmet: Aiming to prevent drunken driving, IIT BHU students came up with the path-breaking innovation of arming helmets with a device that prevents a person from starting his/her bike if the alcohol content in the breath is more than the permissible limit.

The innovative helmet examines the alcohol content in the driver’s breath and sends signals via wireless technology to the vehicle to start or stop accordingly. The helmet uses Bluetooth encryption technology and also featured among the top 5 short-listed projects at the Ericsson Innovation Awards held at IIT Delhi.

Swastika, one of the sacred symbols used by many religions like Hinduism, Jainism, and Buddhism.

The symbol of Swastika is known to signify peace, prosperity, and good fortune in the religious cultures of Eurasia. In fact, this symbol is considered very significant in Hinduism, Buddhism, and Jainism. But, at the same time, it has become one of the most misunderstood religious symbols and has been globally banned in many countries.

The reason why the symbol of Swastika is banned in many countries is because of its association with Adolf Hitler's extreme political ideology, Nazism, as Swastika as its official symbol.

India celebrated a historic day on August 7, as 23-year-old Neeraj Chopra became the first Indian to win an Olympic gold medal in athletics. In the men's javelin throw event, he achieved his greatest triumph, throwing the javelin 87.58 meters on his second try.

Neeraj Chopra was born on December 24, 1997, in Khandra village in Haryana's Panipat district. He grew up in a Haryanavi family of farmers. He is the brother of two sisters. He graduated from Dayanand Anglo-Vedic College in Chandigarh and is now enrolled in Lovely Professional University in Jalandhar, Punjab, pursuing a Bachelor of Arts degree. Chopra was bullied due to his obesity as a kid, which prompted his father to enroll him in a nearby gym. He then joined a gym in Panipat, where Jaiveer Choudhary, a javelin thrower, noticed his potential and coached him. When the 13-year-old Chopra finished training under Jaiveer for a year, he was enrolled at the Tau Devi Lal Sports Complex in Panchkula, where he began training under coach Naseem Ahmed.

Gothic dresses displayed in a store

The emergence of the Industrial Revolution in Victorian England brought with it many apprehensions and fears that translated into a new genre in literature: the gothic. Today, the idea of the gothic does not have to much with literature as much as it is associated with fashion.

The Victorians began to wear black more often during the Industrial Revolution to hide the stains of soot on their clothes. Many of the working class were employed in factories. They were newly introduced to technology, the idea of coal as fuel, and the working of machines to serve a certain purpose. This kind of work was hard and messy. Wearing light colours burdened the tired folk when the stubborn stains did not get washed away.
