Hand operated purifier lets you crank out clean drinkable water

It can be tough to find clean water in many remote places, so having a quick and easy way to purify it is essential. Traditional charcoal filters can be slow, so the SteriPEN Sidewinder uses UV light to kill off any critters.

Large plug-in water purifiers that use UV light have around for years, but in remote areas it can be difficult to find a reliable source of power. With the Sidewinder, you simply fill up the 1-Liter bottle, attach the cranking mechanism, and crank until the green LED lights up.

The SteriPEN Sidewinder is expected to hit the market next month for around $100.
