The "Acuavatio" River Turbine Advances

We checked in with Mauricio that heads the river turbine project for APROTEC--www.aprotec.com.

The Acuavatio turbine that generates an average of 285 W is installed and working great. Since 1 year ago in the village of Calahorra, Department of Choco, 18 families now have light (2 lamps at 15 watts per house), and a station to charge cell phones. Recently, the axis of the helix was modified with stronger material to withstand storm-rains and any river swells.

In Villa Fatima, Department of Vaupes (close to the border with Brazil) everything is ready to place the new Acuavatio that will provide energy for the satellite connection for the first computers in the bilingual (Wanano / Spanish) school. The 8 computers and the satellite connection will be powered by the Acuavatio.

In addition, the position of the blades have been modified in the Acuavatio model that was launched in February this year in Bocas del Guayuriba. After April 2013, the water velocity was high enough to start logging data to document these improvements. Also, a complete revision of the configuration of the blades improved the dynamic stability of the blades while maintaining the same power output.

November 2012

Hi, As the lead on the project, Mauricio Gnecco reports (translated from Spanish by our Executive Director, Anna Garwood): The second phase of the river turbine is advancing quite well. I'm assembling the modified machine with elements based on the award-winning InnoCentive design. For two months, John Burton and I reviewed in depth the aspects of the fluid mechanics of the modifications proposed by InnoCentive. It seems that the angle of the blades will increase the general efficiency and reduce some forces. Please wait for confirmation on these findings. Thank you!

Note we also just sent Mauricio an email for additional information. He could be out in the field working. Stay tuned!

Site Visit

A representative from GlobalGiving met with Don Fabio C., a fisherman on the banks of the Guayuriba River. Don Fabio is responsible for monitoring the testing machine during the "short test" (the first month of testing). Afterwards, a long series of tests should last between 6 and 8 months. By then, molds for the first set of blades can be made, and tested.

Rain during this time was enough to make the usual route too difficult for passage. It took our Aprotec representative an exra hour and a half to reach the testing site.

I'll be checking in with the staffer from GlobalGiving for her account of the visit.
