Useful inventions for the poor

National Geographic magazine has just listed some inventions that are very useful and economical, especially bringing benefits to people in developing countries. These inventions, though very simple, also make the lives of poor people better and better.

These inventions are useful for the lives of the poor

Heating bags for babies

In developing countries, about 19 million babies are born prematurely every year . Many of these were unable to resist because they could not regulate their body temperature. The Embrace heating bag (researched and patented by a group of Indian designers) is designed with a special radiator bag on the back, which can keep the baby warm for hours without affecting the take care of or cuddle your baby.

Handy water container

In remote rural areas, clean water is often very far from residential areas. To solve this problem, the two PJ designers and JPS Hendrikse invented a very compact circular water bottle with a volume of about 52 liters. More particularly, this vase can roll itself, so it takes very little effort to get home water, helping to reduce the burden of work that is mostly guaranteed by women or children. mission. The beneficiary country is South Africa.

Water filter tube

There are about 900 million people in the world lacking safe drinking water. This LifeStraw water filter is designed with an internal bactericidal filter, which minimizes harmful harmful microorganisms, so users can drink water directly at the source by sucking water through the tube. Each filter is about 25cm long and can be used to filter about 640 liters of water. During the Haiti earthquake, thousands of LifeStraw water filters were donated to the people here. A new version of LifeStraw is shorter in size and can filter up to 1,000 liters of water. The first beneficiary country for this project is Kenya.

Chili chill tool

For centuries in Ethiopia , women have to use their hands to crush chili - the country's main and favored spice. This is a time-consuming and painful job because chili oil burns their hands. Pepper Eater chillers invented by Samuel Hamner and Scott Sadlon will help them do this job four times faster, creating more ground chilli pieces and no longer having their hands burned with chili oil.

Sugar cane

In developing countries, fuel is mainly fuel and animal manure. This habit has contributed to devastating forests. Smoke emitted from these fuels also damages breathing. Using crushed bagasse, this can be used to make coal briquettes like this can take advantage of abundant raw materials in many localities, and their exhaust fumes are cleaner than other traditional fuels.

Refrigerated container with clay

This chilled bottle is designed based on a technique of storing food of the ancients. This flask-in-bottle system takes advantage of evaporation from a wet sand layer in between two layers to keep the vegetables fresh longer. This invention is being used by people in rural areas in Nigeria to preserve agricultural products.

Solar roofing tiles

SRS Energy (USA) has launched a special green roof tile.Solé Power tiles do not look much different from traditional clay tiles, but their uses are far different. These green tile sheets are made of a very high molecular weight compound. In fact, they are curved photovoltaic panels that can absorb sunlight and generate enough energy for everyday activities, thereby reducing electricity bills by up to 70%. monthly of Americans.

Solar lights

In many parts of the world, kerosene lamps - a toxic fuel - are the only source of illumination. Two inventors Amit Chugh and Matthew Scott (India) have created a MightyLight lamp using solar energy for lighting. The lamp is not only safer, cleaner but also quite versatile: it can be hung on the wall, put on a table or carried as needed. Moreover, it is very durable with a shelf life of up to 30 years.

Wi-Fi street lights use solar energy

StarSight street light system is a pedestrian lighting system that uses solar panels to provide lighting energy. Each lamp post is also fitted with a Wi-Fi broadcast box, and if required, this street light system can also provide a security surveillance system. As a result, we have an electrical system in combination with very energy-efficient communication. The invention is developed by Kolam Partnership Ltd. research and development. It is expected that it will be applied in Nigeria, South Africa and Turkey.

Battery charger for hearing aids

Projects to provide hearing aids for developing countries may be difficult and hampered by the fact that these hearing aids are battery-powered, but the imported battery has a high cost to people. in disadvantaged areas. Knowing this problem, Godisa Technologies Trust (Botswana-based) has invented a solar-powered battery charger. More than 6,000 units of this type of battery charger are distributed in Africa, Asia, Central and South America.

Cheap laptop

These personal computers were developed and built for the 'One Laptop per Child' project - a project that provides access to computer knowledge and skills for children in remote areas. count. Each computer is equipped with a Wi-Fi receiver via 2 ' is ' above the screen and a screen like an e-book, for use in schools. Uruguay has distributed 400,000 laptops to schools and is ordering 90,000 more.

Affordable solar cake steamer

In some underdeveloped countries, the only way to cook is to use firewood. This not only causes safety, but also leads to deforestation. For many poor people, cooking with gas or coal is too expensive. So a group of engineering students studying at Cambridge University created Infinity Bakery . The oven is equipped with a device that absorbs sunlight and can be heated to a temperature of about 220 degrees Celsius. The highlight of this machine is that it is made of many simple materials like oil recycling bins. , clay and bamboo. In addition, this special oven also helps much to protect the environment as well as ensure safety for users.

Mosquito protection

Malaria, fever, yellow fever are all diseases caused by mosquitoes and these diseases often rage in underdeveloped countries. The invention called Patch Kite promises to be a breakthrough in fighting infectious diseases from mosquitoes. It is designed to protect children and mosquitoes' residential areas. Accordingly, Patch Kite will break down the mosquito's carbon dioxide nerve cells, prevent mosquitoes from attacking humans and it is being designed as a long-term patch to attach to clothing instead of using it. mosquito repellents of unknown and expensive origin.

Adjustable vision glasses

One of the keys to success in life is education, but millions of children are affected by learning due to weak eyesight. In rich countries it is an easy problem to deal with using contact lenses or glasses. But for poor countries, these health-support items are still luxury goods. Developing World Vision Center and Dow Corning Corporation have launched the Vision Child initiative to help children with low vision in rural areas. They design glass that owners can adjust themselves until the eyes see clearly. The glass is also designed to be durable enough to withstand different environments and produce at a low cost.

Self-powered solar water pump

Water pumps are arguably one of the most valuable and useful assets for families with difficult economic conditions but many of the equipment available on the market are often too expensive or complicated to assemble. In response to this urgent need, Pumpmakers created the NSP Solar Pump that helps poor communities who cannot afford or pay for maintenance for pumps. Their goal is to design a pump system that requires no maintenance, no operating costs, and resistance to erosion.

Shelter House

Cheap housing or shelter is always a big concern for the poor. An engineer has created the Hexayurt shelter . It was built with conventional materials and cost less than a tent. Not only is it easy to build, this 'temporary' house can also be collapsed and moved to another place.

Increasing shoe size

Hidden in many parasites, soil is also a source of transmission that makes everyday shoes a necessity for children. However, due to difficult life, even shoes do not have to go, children often have to walk barefoot or wear shoes of the wrong size. Thanks to the invention of The Shoe That Grows , shoes for children will be used for a long time at an affordable price. Because it is made of simple materials, it is easy to clean and adjusted to 5 sizes so they can use these shoes for 5 years.

Lamp from salt and water

When the sun goes down, many rural areas get sucked into the ' i- shadow ' due to lack of electricity. A young engineer came up with the idea of ​​creating a replacement lamp when it was not dependent on batteries or had to use toxic substances such as kerosene. In fact, this lamp only needs 2 tablespoons of salt and 1 glass of water can be lit. A special feature is that this lamp can 'shine' for 8 hours and can be used to charge other devices.
