Iranian Researchers Manufacture Double-Float Wave Energy Convertor
“This device is a double-float wave energy converter that converts wave energy into electricity. The diameter of this converter is 70 cm and its height is 140 cm. Due to its limited dimensions, the device produces 5 to 8 watts of electricity in a frequency wave similar to the frequency range of sea waves,” said Shahriar Mansourzadeh, the director of hydrodynamics research group of the Subsea Research Institute of Isfahan University of Technology.
He added that the pilot model consists of a floating body and a submerged body, including a mast and a horizontal heavy plate, which results in a relative oscillatory movement vertically to the water surface due to the collision of the wave with the floating and submerged bodies, noting that the movement is converted into a rotary movement in a power take-off system (PTO) and then transferred to the axis of an electric generator to produce electricity.
“Actually, the device is a complete laboratory model of this converter, and if we want to make it in real dimensions, we can make this device 10 or 15 times larger than its laboratory model to generate nearly 8 kilowatts of electricity,” Mansourzadeh said.
Wave energy offers a promising renewable energy source, however, technologies converting wave energy into useful electricity face many design challenges.
The WEC converts wave energy into electricity which is considered as a green and sustainable energy.
