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.
