Miniaturna hidroelektrarna za polnjenje elektronskih naprav

The German company Blue Freedom LLC, has come up with a new way of charging smartphones, far from the urban din, in the midst of nature

Solar cells have been replaced by a miniature hydropower plant with a 12‑centimeter turbine which is submerged into water, and houses a 5 W generator and a battery with a capacity of 5,000 mAh. The device is especially intended for people without access to electricity.
