Handheld Turbine Can Generate Power From Wind or Water

At only 1.7 pounds and 7 inches in diameter, this cool little turbine is the perfect packable item for any outdoor enthusiast who wants to charge their electronics while away from civilization. Designed by a Canadian start-up, the Waterlily can generate power from either water or wind to charge you device wherever you are.

The Waterlily’s peak efficiency is a water current of 4.5 mph or a wind speed of 45 mph.  If you aren’t near running water and the wind isn’t gusting, it can also be dragged behind a watercraft to generate the power you need to charge your device.  The Waterlily team is also working on incorporating a hand crank into the design, which will be released at a later date.

Not yet mass produced or available at a store near you, the Waterlily can be preordered at their website for $99 here.
