Trust begets trust It is believed that both ‘cold reasons’ and ‘hot emotions’ are needed to take ‘right decisions’. Trustworthy decisions emanate from a trustworthy mind. Being realistic, honest, and forgiving with yourself and with others Read more...

These 10 Transformative Inventions From 2016 Can Impact the Lives of Millions in India.

These 10 Transformative Inventions From 2016 Can Impact the Lives of Millions in India. 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

A young entrepreneur, Ashwath Hegde, created 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..

3. Self-Repairing Roads

Nemkumar Bhantia, a professor in the Civil Engineering Department at University of British Columbia (UBC) in the Canada, has developed roads that are self-repairing and sustainable. Built used ultra high-strength concrete and special fibres developed at UBC, the first such road in Karnataka is not only cost-effective, but has greater longevity., Banthia’s self-repairing road uses 60 % fly-ash and only 40 % cement. The fibres used have a hydrophilic nano-coating, which attract water in the event of rains. The water then becomes a key component in healing cracks. When a crack appears, this water gives hydration capability to the un-hydrated cement, and produces more silicates, which actually close the crack before they grow larger.

4. Ulta Chaata Harvester

A couple passionate about conservation, Samit and Priya Choksi’s first product is Ulta Chaata, an indigenous patented system that smartly converges rainwater harvesting and generation of renewable energy for open spaces in smart cities, industries, or large campuses. A single unit of Ulta Chata can help you harvest upto 100,000 litres of water and capture energy with maximum peak power of 1.5 Kw.

5. Cane-based Prosthetic Limbs

Bengaluru start-up, Rise Legs, has come up with a prosthetic leg for amputees made of cane, which is not only light but much more affordable too. Conventional low-cost prostheses in India, made of rubber wood or plastic, are often rigid, heavy and cumbersome, which makes walking and high level activities difficult for the user. Modern prostheses, while flexible, are made of material like carbon-fibre and Kevlar that make them far too expensive for most amputees in India.

6. Low-Cost Wind Turbines

Avant Garde Innovations, the startup founded by siblings Arun and Anoop George from Kerala, has come up with a low-cost wind turbine that can generate enough electricity to power an entire house for a lifetime. The size of a ceiling fan, this wind turbine can generate 5 kWh/kW per day and cost less than an iphone !

7. No-Fuel Plough

A farmer in Banda in Uttar Pradesh, 50-year-old Ram Prasad upcycled an old bicycle to make a low cost plough, and then inspired his neighbours to do the same. He converted an old cycle he found in his backyard, with some pieces of iron, into a plough.

8. Solar Power Tree

Developed by the Central Mechanical Engineering Research Institute (CSIR-CMERI), the Solar Power Tree generates the same amount of electricity as a conventional array (enough to light up 5 homes), but on a much smaller plot of land. With photovoltaic panels placed at different levels on branches made of steel, “solar trees” could dramatically reduce the amount of land needed to develop solar parks. Solar power trees are also capable of harnessing 10 to 15 percent more power compared to ground-mounted solar arrays.

9. DewDrop Water-from-Air Condenser

Jawwad Patel, a 22-year-old engineering student from Hyderabad has designed a 3D-printed apparatus which can ‘create’ water from air. The water apparatus produces pure drinkable water with the help of computerised sensor interface with UV filter. In an hour, the device can extract nearly 1.8 litres of water from air.

10. Unique Waste Disposal Bins

Ganga Narayan Ghosh, an 87-year-old mechanical engineer, has designed some innovative waste disposal bins to tackle the problem of waste management in India in an organised way. He designed three unique bins – one for homes, another for housing complexes and schools and the largest one for markets and entire localities.
