I found this on youtube, if you have free flowing water available this might be a great power source.

Interesting. But it should be easier to create 3.3v or 5v from the rain of the roofing...
Not everyone have a river next to the house.

This is not the same. The very first video can power out a big power. Then there is a box transforming it into 230Vac (or 110Vac) 50Hz.
The same box as for photovoltaïque or wind turbine.Then you have you product, who is only for low power device (like ours). But cannot feed an house.
Still, it can be cool for many mysensors device outdoor.
