5 Rural Inventions that can make Harvard Uncomfortable

- By Dwaipayan, 22 September 2020 | 6 MIN READ


Necessity is the mother of all the inventions - a lazily boring quote but a hard-hitting one! From solar-powered freezers for farmers to zero-electricity water purifiers, the inventions that have the potential to dramatically impact the people living in villages. 

Rural India lacks in some of life’s basic needs, such as clean drinking water, groundwater for crops, healthcare, and education. Many villages in India still do not have electricity, while we'll all agree, a power-cut just for an hour or two makes us feel like end of the world.

But there are innovators who are busy bringing in much-needed interventions, the last few years saw some useful inventions changing the lives of people living in rural India.


Purifying contaminated groundwater: Taraltec

Borewell water is affected by biological toxins like microbes and pathogens that can result in unsafe waterborne diseases like diarrhea, cholera, and typhoid. Three cheers to Anjan Mukherjee, who has developed the Taraltec Disinfection Reactor, a ‘fit and forget’ gadget, the disinfection reactor converts contaminated, infested water from borewell handpumps at the source to clean water and kills 99% of the microorganisms present in it.

How does it work: The device converts the kinetic energy of the fluid into millions of targeted micro-bubbles each acting as localized reactors. The process generates intense heat, pressure, and turbulence that release extreme energy packets during the collapse of bubbles. The resultant shockwave, marked by a bang sound, lacerates and kills the microbes.

Shuddham: A low-cost, zero electricity water purifier

The next in our list is a low-cost, zero electricity water purifier by Jitendra Choudhary born to marginal farmers, Jitendra hails from a remote village in Madhya Pradesh – a mechanical engineer by trade. He built Shuddham, a low-cost water filter that can repurpose 500 litres of dirty water for everything except for drinking and cooking. Shuddham uses zero electricity and works on the principles of gravity.

How does it work: The water is cleaned within a few minutes through granular sieving which is later followed by active carbon ultrafiltration.

Ecozen: Keeps farm produce fresh for longer

IITians everywhere are showing their magical charm - three ex-students of IIT-invented a product for farmers to increase the shelf life of their produce and operate in a wider market. Meet the startup Ecozen, Devendra Gupta, Prateek Singhal, and Vivek Pandey developed Ecofrost, a solar-powered cold storage unit that can store produce up to 21 days.

Ecozen preserve produces that tends to spoil quickly, such as green leafy vegetables, tomatoes, or bel pepper, and be stored for up to 21 days. The temperature can be controlled by the farmers from their phones by simply selecting the produce, intelligent isn’t it?

The Focus: It’s just not only on increasing the shelf life, but also to maintain the original quality of the produce.

Drone Ambulances

9.33 minutes is the average response time of an ambulance in India and can extend further in cities due to traffic congestion, while in rural areas the condition of roads could be worse. Goutham Sharma and Jervis Anthony Saldanha got the best remedy, they developed drone ambulances.

The drone is built with the ability to move in tight spaces with vertical take-off and landing, medical emergencies are easy to attend to.

The Technology: The GPS enabled drone can carry a first-aid box weighing 8 kg and fly at a speed of up to 70 kmph. As of now, the prototype can be remotely controlled for up to 3 km, and sooner can be controlled for a longer distance.

Jugnu: A solar backpack

Charu Monga, from the Indian Institute of Technology, Guwahati, announced the development of Jugnu solar bags, that have solar panels integrated into them.

The bag stores enough power during day time for students living in unelectrified parts of the country, the bag is particularly useful in the mountains where they have to travel long distances and come back home without access to the power supply or long power interruptions.


These are the inventive-stories from India’s talented innovators, who trounced all odds and stunned others through their rural innovations. Apart from these wonderful inventions, many inventions remain unrecorded (follow our blogs we will bring you more invention stories from our unsung inventors). Coming from humble backgrounds, these innovators saw the everyday challenge as an opportunity to invent time-saving, energy-efficient models.
