A module to generate electricity from water waves

摘要

The present invention relates to an electricity generating module. In particular the invention has a square base footprint measuring 20 metres by 30 metres with a side elevation of 3 metres high on all sides. It is made of standard range shipbuilding grade steel plate. The structure is anchored to the ground beneath the water. The said structure is a steel box fabrication filed with air, in which a moving water-weighted weight rotates on a central shaft which drives a hydraulic pump. The module utilizes the energy produce by waves of longer lengths: 50-100 metres. The advantage of the module is that no fossil fuels are used as the total energy produced results from the constant and predictable supply of wave motion. There are no carbon dioxide emissions from the device. This module's optimum environment is ideally in 40-60 metres depth of water, 5-10 kilometres from the shore accessing large wave swells. Inside the module a centre shaft continuously rotates due to constant wave motion. The hydraulic pump is connected to hydraulic drives which turn the generators.
