17 year old kid developed cheap way to make salt water potable
This kid is amazing. The 17-year-old Chai developed a logic technology to turn salt water into fresh water.
Over 70 percent of the earth’s surface is covered with water, but only a fraction of it is fresh water. Scientists know how to get the salt out of seawater, but have so far not found an affordable way to do that inexpensive on a large scale.
Chaitanya Karamchedu seens to have the solution.
Chaitanya Karamchedu studies at the Jesuit High School Senior in Portland (Oregon). He taught a way to make salt water drinkable, all of which from his biology room.
“Scientists have experimented with desalination, but that proces costs a lot of energy and money a large scale,” said Chaitanya.
A Kid point of view
His way is said to be cheaper and approaches the problem from a completely different point of view.
“I realized that seawater is not fully saturated with salt. About ten percent of the water molecules are bound to salt, but the remaining 90 percent is actually free. Why does scientists focus that much at that ten percent if we deal with the 90 percent?”
He adds a highly absorbent polymer to the salt water, which adheres to the salt molecules. Then they can easily be separated from the rest of the water.
For example, ten percent is lost – which was attached to the salt molecules – but the remaining 90 percent of the water is fresh water.
Chai won a $ 10,000 reward from the US Agency for International Global Development. He also became second at the TechCon Conference of the prestigious university MIT. There he gained more funds to continue his work because, although the first results are promising, there is still a lot of work at the store.
