Utilizing the power of flowing water, Blue Freedom produces portable energy to charge all your electric devices.

So you need a river for this to be useful. I think you're right that solar is more widely usable.
Or a creek ;) Might be useful in an area that has lots of water, but not very sunny, maybe Northern countries.
Yeah. It's the opposite of California where we're currently suffering severe drought.
