Proposal
Imagine being at a place in summer when it is boiling hot and you have to suffer from the burning sun and the intensely hot temperature at the same time. It sure would be terrible and frustrating. That is the summer of China.
Many places in China are fervent, such as Chongqing and Wuhan. Both Chongqing and Wuhan's hottest days are in July and August. In 2012, the average temperature of the hottest month was about 30 degrees Celsius for Chongqing and 33 degrees Celsius for Wuhan. In comparison, Vancouver's hottest month's average temperature usually ranges only around 22 degrees Celsius.
Two factors contribute to the terrible heat in many cities in China - lack of plants and massive population. Even though China is the third largest country by land, population is unevenly distributed, with more people living in popular places like Beijing, Shanghai, and Hangzhou. As such, population in China’s major cities is a huge problem. With so many people in one city, the amount of carbon dioxide in the air increases, from the breathing process as well as use of cars and air conditioning. To provide accommodation for the growing population, China builds many tall buildings which have taken away the space for trees to grow. While trees take in sunlight, water and carbon dioxide and produce oxygen and sugar. Lack of trees elevates the amount of carbon dioxide in the air. On the other hand, the amount of carbon dioxide produced form an invisible 'blanket' in the sky on top of the cities. The blanket acts as a shield to stop heat from escaping back to the atmosphere; consequently, heat is retained in the cities and causes unbearably high temperature. A look at the big cities in China reveals many concrete roads and highways and very few plants and trees. The absence of plants and trees and the reflective nature of concrete further add to the heat in the cities.
The UV ray of the sun also has a great effect on increasing the temperature. When the sun is out, the temperature increases.
Having extreme hot weather in the summer can be annoying and frustrating. It could also lead to water loss. Yet, we can turn this negative effect into a positive source. We can use heat to vaporize endless sea water and turn it into water with neutral pH level.
Water, the amazing substance, supports all lives on Earth. Although 2/3 of the Earth is covered with water, only 1% of the water is drinkable and available to us. While 2% of water is in ice caps and glaciers, the rest of the water, 97% of it, is salty ocean water. The saltiness of sea water makes it undrinkable. While the salty sea water sucks out water from human's body cells through osmosis, drinking salty sea water will cause dehydration.
In our invention, my group attempted to use Eco-friendly means to turn salt water into water with neutral pH level. We believe that mastering this skill means humans will never die from thirst. We are reminded of the importance of water in the human body systems. Indeed, we can only function when there is enough water in our body. As a human’s body is made of 60% water, water is constantly lost in many processes in the day, such as breathing, sweating and urinating. Water lost must be replenished because water is required to maintain the volume of blood and other fluids in our body. As well, water is needed to regulate human body temperature to reach an internal temperature at 36.5 to 37.5 degrees Celsius. On the other hand, water transports nutrients within our body and flushes toxins out of our body. Therefore, in order to keep our body in good balance, every person need to drink at least 64 ounces of water per day, equivalent to 8 glasses of water.
What if a person does not get enough water in the body? Lacking sufficient water in the body over time will cause blood vessels to close and the blood to become thicker. Thicker blood in a body means the blood will clot more easily and is harder to pump through the body system. Huge health issues such as hypertension, heart diseases, headaches, heartburn and arthritis will result. On the other hand, intense dehydration can kill a person. In fact, a person can die out of dehydration without water for three days.
In view of the importance of water in keeping a person alive, it is imperative to have sources to access fresh drinking water. Turning salt water into drinkable water with neutral pH level by evaporation is a good alternative.
