The climate change has caused the focus of scientists and researchers to shift towards renewable sources of energy that don’t add to further climate change. One such source is known as wave energy – the idea of making use of ocean surface waves’ movement for the creation of electricity. This approach is an alternative to making use of fossil fuels such as gas, oil and coal. Did you know coal mining causes pollution? A young engineer has recently created a drone to combat the coal mining caused pollution. The wave energy comes with certain benefits that other renewable energies can’t promise; efficiency, accessibility and predictability.
Pelamis Wave Power is a Scottish company that has created Pelamis Wave Energy Converter. The contraption is the world’s first commercial gadget that can generate electricity by making use of ocean wave energy. Following six years of research, the company has already installed generators in Portugal close to the town of Povoa de Varzim. This installation is touted as first commercial-scale wave power station!
Its peculiar name is credited to the unique shape that it takes; of a yellow-bellied sea snake that is found in tropical and subtropical waters and called ‘Pelamis platurus’. The contraption itself is comprised of three cylindrical sections that are connected together to form a length of 142 meters and about 3.5 meters of diameter while being partially submerged.
The waves cause movement in these three sections and trigger a hydraulic system located within. This system pumps high pressure oil via an assembly of hydraulic motors. These motors are connected to an electrical generator, which generates energy that is then delivered to a base located on sea bed.
The energy recovery system has been designed while keeping in mind that it will be facing some extreme weather conditions. The whole system has been designed to be environment friendly by placing a limit on the use of chemicals that can cause a reduction in coral growth and thus imparts a very low impact on the marine life.
