Answer:

Inventions are not everyone’s cup of tea. They require observation, passion, patience, and perseverance. More than anything else, they need gumption and hard work. However, truly transformative inventions happen when idealism meets the incredible ideas of people who question the status quo, who defy logic, and those who love to take the road less travelled.

The year 2016 saw many ingenious invention, with people across the country picturing a better world and finding a solution to make it happen. From solar trees to self-repairing roads, these inventions have the potential to dramatically impact the way people live.

Here’s a list of 2016’s most impactful innovations that offer solutions to some of India’s most pressing problems.

1. SuryaGen Solar Water Purifier

Developed by IISc. researchers and Suryagen Renewables, this open source solar water purifier can transform water from any source – be it from sea, river, pond, wells, or even water collected from rain – into potable water. The low-cost device can also provide clear drinking water in areas where the only sources are contaminated with arsenic, fluoride or sewage.

In this device, impure water is evaporated using solar energy and the vapours are condensed to pure water on a cold surface. This leaves behind bacteria, heavy metals, arsenic, fluoride and other impurities. It can effectively produce 1.5 litres of potable water from 3 litres of impure water daily.

2. Envigreen Edible Bags

India has been moving away from plastics for many years and many cities have already issued plastic bag bans. While legislation like this helps to protect our environment and wildlife, a young entrepreneur, Ashwath Hegde, noticed that it was a hardship for many Indians.

“People were concerned bout how they would carry products from the market now. Everyone cannot afford a bag worth Rs. 5 or Rs. 15 to carry a kilogram of sugar,” says Hegde. So he decided to come up with a solution that would be sustainable and affordable.

He eventually landed on a combination of natural starch (from potato and tapioca) and vegetable oils to make a bag that looks and feels just like plastic with none of the negative environmental impacts of a plastic vessel. EnviGreen‘s bags will naturally degrade in 180 days and if they are submerged in water they disappear in a day. Oh and also – these bags are edible. This means that when animals encounter non-degraded bags, they can eat them with no adverse effects.
