Hydrokinetic turbines (HKTs) are a promising technology for electrical power supply in small
remote villages located in fairly flat, high rainfall country where other renewable energy
technologies such as wind, solar and conventional micro-hydro are not suitable. However,
clogging by floating debris has been identified as a major problem for HKTs in many
waterways, and particularly in tropical rivers. To overcome this problem, an axial flow HKT
has been designed using conventional wind turbine blade element theory and modified so …
