Harvesting electricity from ocean waves is possible and a group Costa Rican Scientist They work hard to achieve this goal.
Christopher Vega and Juan Guerrero, two scientists from the School of Mechanical and Electrical Engineering Technological Institute of Costa Rica (Tec), They are the leaders of this project E.Wave: Wave energy system for power generationThe investigation began in 2015 with the goal of harnessing Costa Rica’s abundant wave energy and coming up with a more efficient extraction system, Tec reported.
Vega and Guerrero confirmed that among clean and renewable energy sources, ocean energy is one of the most expensive.
“In fact, when we compare ocean energy to wind or solar, ocean energy is four times more expensive,” said Vega, who holds a master’s degree in mechanical design and simulation from the University of Freiburg in Germany and a doctorate in surface modification for mechanical applications from the University of Sydney in Australia.
His colleague Juan Guerrero added High production costs are a limitation Therefore, in order to develop such a project, Costa Rican scientists They are committed to creating a more efficient device that gives you more power at a lower cost.

“That is, they are able to produce large amounts of energy economically; once implemented, the cost per kilowatt will also be cheaper,” Tecnológico reports.
According to research Costa Rica: Identifying ocean power generation potential Produced in 2013, National marine resource potential (Waves, Currents and Tides) Its power is 2.3 gigawatts.
“The 2.3 GW figure tells us that if we take into account the power consumption of an average house, the scheme could continuously power six million homes per month. That means we have a lot of potential,” explained Guerrero, who holds a master’s degree in mechatronics science from the University of Aachen in Germany and a doctorate in optimal control systems from the University of Sheffield in the UK.
The device
The energy converter developed by the Costa Ricans works like this: The movement of the waves agitates a floating buoy fixed to a swinging arm.
“The movement of the arm activates the generator, which converts the energy of the wave motion into electricity,” Vega explained, noting that the movement is converted into energy.
Currently, scientists are focusing on the operation of the device. The aim is to place devices called farms in the ocean to extract more energy and reduce costs.
“This will ultimately make it easier for us to bring all our energy to the coast of our country, and ultimately it will also mean that we can improve the energy matrix in Costa Rica,” Guerrero added.
Currently, countries such as Ireland, France, the United Kingdom, Italy, Portugal and Spain have prototype devices in their waters that use waves to generate electricity.
