More on the Winning Design for the River Tubine

A parts list, and plans:

Uses only inexpensive and standard components:

1. Small trailer axle ball bearing (really barrel). The stress of rolling this machine would be no threat for these bearings, as they are intended to carry a much heavier load.

2. Standard steel tubing and flange.

3. A bicycle wheel acts as a 28 inch low cost pulley.

4. Wooden lateral wings to make a Venturi flow control.

Designer will complete the first prototype in their shop, and then travel to Columbia to help for the initial installation, fine tuning, and tech training-- TBD.

A team of engineers from our in-country partner APROTEC will work with the community to install the equipment and do follow up tests and monitoring for at least 1 year.
