THE SUSTAINABLE POTENTIAL OF HYDROKINETIC TURBINES IN THE AMAZON BASIN

Anais do Congresso Nacional de Excelência em Gestão, 2023
The Amazon, rich in biodiversity and natural resources, seeks renewable energy sources to minimize environmental impacts and reduce dependence on non-renewable sources. Hydrokinetic turbines emerge as a promising alternative by making it possible to convert the kinetic energy of river currents into electricity, without the need for dams.

Experimental research on a hydrokinetic turbine model

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The renewable energy policy strongly encourages the use of all renewable sources of energy. ICPE-CA starts to develop a new hydrokinetic turbine to be implemented in small rivers or water channels with a low investment cost. In a first step, the characterization of a laboratory reduced scale turbine model is performed.
