Charging Remote Devices

Here’s a small turbine that can be immersed into a stream or mounted on land to catch the wind, whose promoters claim is good for powering remote devices.

No one says this is impossible, but at $269, isn’t it extremely impractical, given that alternatives include a $23 piece of solar PV or a $40 hand crank generator?

I note that they’re taking “pre-orders,” meaning that the product hasn’t even been built yet.   Hmmmm.
