10 Simple Inventions That Changed The World

There have been 10 simple inventions in the scientific world, which are not only the latest in terms of technology, but they have played an important role in providing services to people in the world, especially in poor countries.

1. ORS - Oral Rehydration Salts

By the 1990s, diarrhoea had killed more than 5 million children under the age of five worldwide. This number was later reduced to 1.5 million due to ORS. ORS can be easily prepared at home by mixing it with water. Probably this simple discovery has saved more human lives at a lower cost than any other invention.

2. Low-cost irrigation methods

`

Irrigation is considered to be the largest source of freshwater use in most countries, accounting for about three-quarters of total use. However, drip irrigation consumes half the amount of water used in the traditional way. However, this technology is modern and usually requires electricity. A Western technology company has introduced a solar-powered drip irrigation system that makes it possible to reap many benefits at a very low cost.

3. Smart power generating networks

Solar cells can provide decentralized with cheap electricity. However, if you are delivering it to a normal home network with traditional tools and equipment, then there are a lot of costs associated with completing this process. In such cases, micro-DC networks designed specifically for this purpose provide a large amount of energy in the traditional framework, saving huge costs.

4. Better wood stoves

Deforestation is considered a major challenge in many developing countries. An example of this is the damage that humans experience when they breathe in the smoke from burning wood stoves. However, well-designed stoves use only half the amount of fuel. In addition, their emissions are halved. The use of these stoves was tested in the Sudanese province of Darfur after the war and widespread displacement. In this regard, 27,000 stoves were manufactured.

5. Simple and effective water filters

Millions of people around the world lack access to safe drinking water. In this regard, the idea of ​​low-cost simple water filters came up. This technology has improved the lives of millions of people.

6. Hypo cylinder

Millions of people around the world, especially women, are forced to travel long distances every day to get water to meet their basic needs and to bring it home. Hypo Cylinders has made this laborious process easier. It is a plastic drum that can be filled with water. It can then be rolled into a drum and delivered to your home.

7. Jet injection

Today, vaccination is considered essential for public health. However, the distribution of vaccines at the desired location is a major problem in developing countries. In this case, the idea of ​​jet injection proved to be very effective, which offered an alternative to the constant need for a traditional needle for vaccination. This practice has been around for decades. In this procedure, the fluid is sent directly into the human skin through pressure, rather than through a needle hole.

8. Paper microscope

Microscopes are considered essential for diagnosing gastrointestinal diseases. However, this microscope is sometimes the worst tool due to its weight, high cost and maintenance issues. The solution came in the form of a paper microscope. These are also known as foldscopes. They contain all the basic components of a traditional microscope. They are foldable and cost no more than a dollar.

9. In the case of natural disasters

Telephone communication system

We all know that mobile phones have now spread to poorer countries. However, when it comes to natural disasters, the equipment on which telecommunication networks rely can fail. An alternative is a system introduced in Chile called SiE. This system converts text into high-frequency audio tones through coding. These tones are distributed through radio waves that can be received on any smartphone without internet infrastructure. The smartphone application converts these audio tones back into text messages.

10 Malaria Mobile Checkup

Around the world, about 12 children die of malaria every day. Early diagnosis and prompt treatment are crucial. However, the analysis of blood samples requires a microscope and a reliable technician. A fast and simple system in this regard was introduced at the University of Southern California last year. It is a mobile system that detects the level of haemoglobin released from malaria parasites. It can be used to track the progress of the disease.
