Depletion of fossil fuel as well as increasing in price had pressured the world energy to give focus on renewable energy. This paper interest is to describe the conceptual design of a floating multiple-rotor water current turbine (FMRCT) as well as to investigate the effect of distance between two rotors over diameter ratio (S/D) towards power output increment. Further, the contribution of each rotor toward the FMRCT power output increment also will be discussed. With the interest to increase output power, FMRCT concept design is where few rotors were arranged in series with a suitable distance between each rotor, fitted with a floater at one end, and connected to a generator at the other end. The FMRCT model was tested in an open stream at Lata Ulu Licin (Lecin). Results show that increment of the output voltage is very significant as S/D increased up to S/D = 1.48. Furthermore, extra rotor on FMRCT also proportionately increase the power output, ranging almost similarly from 6.28% to 8.91% of power.Downloads
