Self filling water bottle

I found those articles about a self-filling bottle, this is a great idea, and the concept is great. It’s just like magic, it creates water out of thin air.

TechInsider: The Fontus, self-filling water bottle

LiveScience: Self-Filling Water Bottle Converts Humid Air into Drinkable H2O

Ok, it’s not magic, it’s physics. I love physics! But reading the article I found out the small prints of the prototype.

As written in the LiveScience article:

Fontus can produce 0.5 quarts (0.5 liters) of water in 1 hour in what is considered “really good” conditions, with temperatures between 86 degrees and 104 degrees Fahrenheit (30 to 40 degrees Celsius) and between 80 percent and 90 percent humidity, Retezár said.

So it wouldn’t work in a desert, or a dry place. Where we could need it. But for the occidental people doing sports, it should be enough to keep them hydrated. And it could finance the water harvesting projects to help the driest countries to grow food.

The product is not prefect but it should be available this fall. 

Happy learning.
