Micro Wind Turbine

"Electronic devices play an important role for our activities in the great outdoors. They are essential for navigating and documenting our adventures, for scientific surveys or acquisitions and even for rescue operations and disaster management. Nonetheless, charging electronic devices during long periods away from civilization remains a difficult task. Today, solar panels are the only available solution to this common problem, making the power supply completely dependent on weather periods with sufficient sunshine. This is why the Micro Wind Turbine proposes a novel alternative that can operate in harsh weather conditions and even at night. The design integrates all necessary components in one sleek unit and is focused on pack size, minimal weight and ease of set up."

Charging at night is attractive. Back-of-the-envelope math indicates this thing would "pay" for its own weight, vs carrying a kg of extra batteries, within a week, if used for several hours a night. So, there should be a market for film crews on major expeditions, drone-footage addicts on longer camping trips, etc. For folks who just need to recharge the GPS or camera every few days, a handful of batteries makes a lot more sense.
