Human inventions with a slightly different use
Today I felt I had to write a positive post. I have written a collection of sad and worrying posts on this website. They are all showing that there are a lot of worrying things happening in our world. But today I decided to present you with something different and nice. New uses for human inventions. I think these are great ideas, and while investigating, I have come across some amazing things.
How to help an injured turtle with a bra clasp
This might make you smile, but it is serious and nice at the same time. Do not throw your old bras away as they can have positive and alternative uses. Who would have thought that? Those little hooks on the back can save a life. Now, how nice is that? Here comes the story.
Jennifer Gordon is the director of a North Carolina animal rescue. She reports that at Carolina Waterfowl Rescue, an unusual method is used to repair the cracked shells of turtles. Yes, those small iron clasps are used to hold the crack together, waiting for the shell to heal. First of all, the crack is glued, then a wire is used to complete the repair job with some bra clasps.
Do not miss this very short but powerful video.
Between 3 to 40 turtles might be treated each week depending on the season. They bring many injured turtles in during springtime. The turtles leave their regular homes, like ponds and lakes, as they come out to lay their eggs on land.
I have seen this myself as I have turtles in a big fishpond. Some years ago, while cleaning the area, I discovered a nest with 6 tiny turtles, probably just out of the egg. They were no bigger than a Euro 50 cent coin. After checking that they were all OK, I carefully introduced them to the pond where their parents and brothers and sisters live. The big ones are huge, bigger than 2 hands held together.
When the turtles leave their natural habitat, there are many dangers lurking out there. When crossing the road, they might be run over by a car. A dog might get curious and give it a bite, or a lawn mower might injure the poor animal.
All kinds of different turtles might be brought in to the center. Little ones, no bigger than a silver dollar sized eastern box turtle have been treated. It has also happened that a huge, 14-inch snapping turtle was taken in for treatment.
These animals might stay from 3 to 8 weeks until their shells have completely healed. Then the big day comes and they take the bra clasps off and they release the turtle back to its home. I think this is a lovely story.
A not so good human invention, plastic bottles
Plastic bottles are bad for your health and pollute the environment. Actually, even if convenient, this invention is not a good one. Luckily there is a great way, instead of throwing those bottles out, to use them as a building material.
How to build a home with plastic bottles
Countries like India, South America, and in certain parts of Africa have built houses with plastic bottles. The concept is easy enough. They fill the empty bottle with sand or with waste which cannot be recycled and there you have your building brick. The fill material just has to be small enough to fit through the opening. Once filled, they lay them in a row with cement or clay to fill the gaps.
We can build a lot of structures this way. Houses, greenhouses, and even water tanks can be built using this technique. Whatever you can imagine. On top of the fact that this is a great way to use a waste product, these “bricks” insulate very well in a tropical climate and as total, the investment is extremely low. It might take some time to get enough bottles together, but it is worth the effort.
In Honduras, they constructed a house with 8000 PET bottles and it has a green roof with sod and turf. This is a super insulated house with very low heating and cooling costs. Having used 8000 bottles, it liberated the local landfill of approx. 12 cubic meters (m3). When this roof gets wet, it can come to weigh up to 30 metric tons (Mt, tonelada) but the plastic bottle brick can easily support this weight.
A house build like that can last a good 300 years longer than many modern buildings. Plus the fact that it reuses plastic bottles makes this a brilliant solution.
More excellent uses for a plastic bottle
There are places in our world where people do not have electricity and a water bottle could help with this problem. Have you heard of a Solar Bottle Bulb? Have a look at the following YouTube video which shows how to make such a light.
This video shows you how easy it is to make this solar light.
Such an ingenious invention from a Brazilian engineer. This special system uses a 1.5-liter soda bottle and produces 50W just like a normal light bulb. How cool is that?
How a condom prevents mothers from bleeding to death
It is the year 2000 when Dr. Sayeba Akhter, chair of Dhaka Medical College Hospitals (DMCH) Gynecology and Obstetrics Department, noticed many women after childbirth would bleed to death. In Bangladesh, 30 to 40 years ago, this was the primary cause of high maternal mortality rate.
This condition is called postpartum hemorrhage and doctors would proceed to take out the uterus to prevent this bleeding, but that made it impossible for the women to have more children.
Dr. Sayeba discovered a very simple and cheap procedure to stop this bleeding. This is now known worldwide as condom catheter tamponade or just simply the Sayebas method.
It happened that one day 2 women literally died in front of her eyes after giving birth. She said, “I suddenly visualized the children in the village playing with balloons and wondered if filling a balloon with water and inserting it in the uterus that the pressure created would stop the bleeding”.
She went to the hospital the next day and stopped the doctors operating to take out a woman’s uterus and applied her method for the first time. By using this pioneering method of a catheter, a condom, some string, and a saline set and a saline solution, the innovative idea functioned, and the bleeding stopped within 10 minutes.
Using this procedure devised by Dr. Sayeba has saved the lives of millions of women worldwide. It is extremely cheap, as it only costs about 99 cents. This method is being used in Bangladesh, India, Nepal, Sri Lanka, and Canada.
These were just a few examples of reusing known inventions. Quite amazing, don’t you think? It made me happy to discover these stories, and that is why I wanted to share them with you.
