A portable wind turbine that weighs 3 pounds and has its own battery

Canadians Cat Adalay and Rachel Carr created the $325 Shine portable wind turbine, which is about the size of a one-liter water bottle. The crowdfunded effort received $400,000, according to Core 77.

Once set up on its tripod, the 3-pound, 40-watt device automatically rotates towards the wind and starts charging its 5V, 12,000 mAh battery.
