7 low tech inventions revolutionising the world
We live in a world of high-tech gadgets, with days filled with thinking about how AI could revolutionise our lives in the next 10 years.
But there is one more thing that inspires us: simple inventions that smartly solve the world’s problems. There are still people in Africa and Asia who travel miles for water, don’t have access to clean water, refrigeration, and safe cooking fuels. These are the problems the world needs solving.
Solutions need to be low tech for developing countries, as they do not have access to high tech maintenance, nor the finances for it.
Here are 7 such low-tech inventions that are revolutionising lives in developing countries:
The famous wind-up radio that helped combat AIDs in Africa. It did not require batteries and helped in communicating information to those affected by the disease.
Cheap and low-power irrigation for cheaper, better crops. GEAR Lab at MIT developed this low-pressure, solar-powered drip irrigation system to help farmers cultivate crops.
A simple water filter that uses silver nanoparticles and ash to filter our impurities, help save thousands of lives.
The "Hippo-Roller" is a low-tech solution to help women transport water. A huge high-grade plastic bottle that can be rolled home.
Paper microscopes could revolutionise healthcare, costing less than $1 to make.
This non-electrical refrigeration that uses wet sand between two clay pots to keep things cool.
The Berkeley-Darfur Stove that uses half the amount of wood fuel, helping reduce exposure to harmful particulate matter while making the same amount of food.
