Hydrogel water source

Researchers at the University of Texas have combined materials that absorb water from the air and release it using sunlight. The hydrogel is so efficient that a kilogram can produce 50 liters of water per day.

In a wilderness or survival situation, the rule of three applies – you can only go three days without water. A 1/2 pound of this gel could provide roughly six two-liter bottles of water per day – far more than needed to survive – with zero energy needed other than the sun.

Let’s hope a kit starts showing up on survival shop shelves in the next year or so! Click here to read article: HYDROGEL
