Blue Freedom: a portable hydropower plant

Blue Freedom is an electrical generator that produces portable energy to charge any electric devices using the power of flowing water. The electric current has a power of 5 watts, enough to load different devices connected to the USB port of this tiny hydroelectric plant. Depending on the strength of the watercourse it is able to produce just in one hour enough power to run a mobile phone for about ten hours.
