An AMAZING IDEA!!!!!!!!!! SMALL IS BEAUTIFUL!!!!
INDALMA, a large family small business arrived on simultaneously with the environmental and petroleum world crises. Family members invented and patented in 2002 a hydroelectric turbine that supersedes other turbines on the national market by its simple construction, easy operation, low maintenance, low cost and operational capacity in low water sheds (minimum of 4 meters).
INDALMA works out of Santarem, population of 272.000, situated in the Lower Amazon Valley. 89% of the rural population has no access to electrical power. Presently INDALMA is negotiating with a federal government program – Light for All – to offer one phase and three phase electrical energy to isolated communities throughout the whole Amazon Region.
Since the year 2000 INDALMA has installed 80 mini hydroelectric turbines in private farms and in 45 rural communities with complete success, with minimal maintenance costs and environmental impact.
Small earth damns, at most 9 meters high, are constructed near small water supplies forming ponds or small lakes. From a concrete spillway water is supplied to turbines located at the base of the dam, which in turn activate traditional generators. From the powerhouse one phase and three phase stable energy is distributed in all directions to distances of 30 kilometers.
A local community association administers the project. People are trained to keep the spill way clean, to lubricate the turbines, to read the meters for electrical consumption, to bill the people. All profits are reverted back into community projects. Once constructed, there is very little maintenance cost.
In September 2005 the municipality of Santarem entered in partnership with INCRA, a federal land reform institute, to construct 6 mini hydroelectric plants, supplying energy to 1890 families in isolated areas of Santarem.
