Optimised design and dimensioning of low-technology wind pumps

This article describes the currently operational version of the low-technology wind pump of high efficiency, as presented in [Valdès L-C, Raniriharinosy K. Low technical wind pumping of high efficiency. Renewable Energy 24 (2001) 275–301]. The pump, made entirely of wood and using roller bearings for the rotating links and a rubber membrane for water tightness, is of a more modular conception. Its manufacture is slightly more complicated, but its dimensioning has been greatly simplified, its reliability significantly improved and the use of wind energy optimised.
