Harvesting energy from ocean wave is a promising renewable energy source due to its high efficiency, carbon-free, it is not affected by depletion of fossil fuels, and it is replenished constantly. The existing generators used in wave energy harvesting such as linear generator and slider crank mechanism have some limitations, which include lower efficiency and technologically challenging. Thus, in this work, wave energy harvesting technique using rotational generator based on scotch yoke mechanism is proposed. A typical slider crank to convert linear motion into rotational motion is replaced by scotch yoke mechanism to yield higher efficiency. A comparison of the performance of wave energy system between employing slider crank and scotch yoke is made to evaluate the superiority of the proposed mechanism. From the results obtained in this work, it is found that the output voltage of rotational generator employing scotch yoke mechanism is higher compared to that of rotational generator employing slider crank for the same input power. Thus, rotational generator by employing scotch yoke mechanism can be one of the alternative methods for ocean wave energy harvesting.

“…Wave Energy Convertor (WEC) devices are used to convert wave energy to other types specially electricity, which is widely reported in literature (Hollm et al 2022, Choupin et al 2022, Xu et al 2017, Korde et al 2016). Although there are lots of Wave Energy Converter techniques around the world (more than 1000), they fall into three main types including: Attenuator, Point Absorber and Terminator (Drew et al 2009) which some are common methods in desalination are discussed brie y here.…”

Using wave energy for desalination is recently noticed by researchers and authorities. This is known in industry as wave to water and is especially vital for regions/islands where have access to seas and oceans but suffer from shortage of drinking water. Some devices are developed to perform this operation in industry sector as well as academic studies performed in this regard, yet study on geometrical optimization of these devices is required. Studies aiming to optimize the wave energy convertor (WEC) geometry are expensive in eld. As a result, investigations are divided into numerical and experimental studies in which the former requires validation by observed data. In this paper, a preliminary experimental study on parameters affecting the performance of a paddle type WEC, such as paddle width, water depth, coast slope, and wave frequency period on the performance of the converter is conducted by running laboratory tests. This kind of WEC is used in industry. Analysis to scale up the results are provided and discussed in detail.
