Cooped Up? Get Uncooped.

Filtering and purifying water can be a lot of work, particularly if you don't have handy device to do it. You'll have to build a fire, heat the water, let it cool and repeat every time you need a drink. That's what makes this SOLARAQUA design by Jason Lam so practical. Fill it up, allow it to sit in the sun and UV and infrared from the sun's rays will kill all those nasty organisms just itching to get into your intestines and send you to the toilet. In the meantime, you can do other things like build a shelter or hunt for food. The unit also includes a sari-cloth filter so filtering larger particles is taken care of with one easy process.

Each of the pedals fill with water and gain plenty of sun exposure providing a total of 10 liters of potable aqua. The black bottom of the pedals attracts heat and then the interior reflects the rays, providing thorough UV purification. Given the massive size of this design, it would probably be more useful in a disaster-type survival situation in which the water supply was contaminated. I can't quite see carrying this around in the backcountry and I suppose you'd be screwed if it was cloudy. And that's exactly what the device will be used for--purifying water in parts of rural Africa. Tuvie via DVICE
