Bicycle hub hydropower

[Niklas Roy] wanted to create electricity from moving water so he came up with this hyrdopower generator. It is part of his grand scheme to rent out small personal fountains made from buckets. They need electricity to run so he hooked up the generator to the water jet of a public fountain. It should be possible to use this setup with falling water in a similar way that other generators do.

To build the device he cut fins out of PVC pipe to use as the scoops. They are attached to a Shimano hub generator, meant for producing power while you pedal. The hub is mounted in the front for from a bicycle, which can then be mounted anywhere moving water is available. The only thing that worries us about the setup is [Niklas'] comment that being showered with water didn’t destroy the hub right away.

See the hub and the smaller fountains in the clip after the break.
