When was the last time you were afraid because you didn’t have any fresh water to drink? The only struggle you might have is getting out of bed to walk to the kitchen sink. Unfortunately there are millions of people in Africa who don’t have it so easy. They might have to walk miles and miles if they want water and even then there is no guarantee it’s safe to drink. Can you imagine how hard life must be when it’s almost impossible to quench your thirst?
Luckily there are smart inventors all over the world who are trying their hardest to make things easier for people who don’t have access to clean drinking water. Once this happens it will improve everyone’s health and less people will die each year. Some of the inventions they’ve come up with are very interesting, so I thought we could look at some of them right now. I’m sure you’ll be impressed by the wonderfully creative technology they’ve come up with.
LifeStraw is one of the most amazing straws in the world because it allows people to drink from water no matter how dirty it is. These days it contains no chemicals and the water has to pass through a mechanical filter where it’s turned into safe drinking water. The outer shell is made from hard plastic and people can wear it around their neck. The only downside is the fact the unit needs to be replaced every year.
They say the average distance an African has to walk for water is nearly 4 miles. Instead of someone carrying a few buckets of water such a long distance they’ve come up with a machine that can hold 50 liters of water. It has wheels so it’s easy to push over long distances and as the wheels turn the water inside the machine purifies the water so it’s safe to drink. When someone buys a Midomo bracelet a machine is delivered to an African community.
This device is similar except on a much smaller scale. I’m sure you’ve seen a Jerrycan before even if you’ve not had the pleasure of using one. The reason this one is different is because it filters the water making it safe to drink. Each family will be able to use one for up to 5 years before they need to replace it. It’s can’t store as much water as the Midomo because this one is capped at around 18 liters, which still isn’t too bad when you think about it.
The Slingshot is what happens when a great inventor teams up with the biggest beverage company in the world, Coca Cola. Dean Kamen’s water purification device is another way to help people gain access to fresh drinking water. This one is the size of a small fridge and it’s capable of producing over 700 liters of water per day. It can be powered by cow dung with the help of a generator and it will also produce a small amount of electricity to light up people’s homes.
Making a difference
We read about amazing technological advancements every day, so it’s nice to hear about ones that are specifically trying to improve the health of the less fortunate. Nobody deserves to die of complications caused by a lack of clean water, yet it’s still happening all around the world at this very moment. Most of us care about buying new computer games or designer clothes, but I’m sure a few thirsty people will feel the same level of excitement about the things we’ve spoken about today.
