Finish Line Before Summer:

Get Rid of Water, Charge From Water, Analyze Water

Water is a pest, water is the source of energy and water is the material for analysis. We've gathered all the three of these normal water qualities in our May collection of gadgets.

Enterprising businessmen from DryBox opened "rescue stations " for drying flooded phones in Texas. These "stations" look like a dryer and an operator who lays a damaged phone in the unit. DryBox promises that if a wet mobile phone is put in their vehicle within 36 hours after soakage, it will be revived with a probability of 75-80%.

Mobile phones are being dried for about half an hour, the service costs from 30 to 60 dollars. Now ovens can only help patients with gadgets no larger than Samsung Galaxy III. But the company plans to fully automate their equipment, and tablets like iPad Air will fit in the device. The owners will put in their gadgets and remove them by with no assistance.

DryBox strongly recommend not to use a popular method of drying flooded telephones putting them in the container with dry rice, because in this case drying time cannot be controlled, and overdrying threatens with barley dust inside the poured gadget. DryBox is proud to add that they have already got regular clients who bring them watered smartphones not for the first time.

Another telephone and water news from the U.S.: the Polytechnic University of Virginia has developed batteries that run on water. Their creators claim that the water batteries will beat much less capacious lithium-ion batteries. In the human body glucose becomes an energy source due to the decomposition into carbon dioxide and water with electrons release. And bio- batteries work on the same principle.

"For example, if you are using lithium-ion battery, your phone can work only one day. But the phone can work 10 days on bio-batteries"- University member Chzhiguang Joo promises to gadget fans.

And a bioengineer from Stanford University came up with a toy, which can make an express water analysis. Or check the composition of the soil. Bioengineer Manu Prakash was inspired by a music box construction and put together both traditional and modern technologies in a small and very simple chemical lab. 


It works like this: turnung the handle makes punched card pass through the device. A pattern of holes in a punched card shows substances of the analyzed material. Low capacity chips can contain up to 15 different chemical substances. They can be poured into the 'box' by adults. "This unit is fully mechanical. It has no electronics and no batteries, "- Prakash says about his invention.

The toy was invented by Manu Prakash and his graduate student George Korir. The first one was born in India and the second one was born in Kenia, and both of them believe that children of their countries need such cognitive and cheap toys which cal help to make them interested in science since childhood. Chemical laboratory set costs only five US dollars and the authors suggest to use it not only for children but also for adults to make rapid water and soil rapid tests.
