Algorithm Doubles Electricity Yield From Ocean Waves

Algorithm Doubles Electricity Yield From Ocean Waves

Wave power could contribute to the renewable energy portfolio in the future. At the moment the technology isn’t advanced enough to generate electricity from ocean waves commercially. But the growing interest in renewable energy has motivated several  companies to invest in wave power research.

The British company Pelamis Wave Energy is currently testing its second generation Wave Energy Converter the Pelamis 2 a.k.a. P2. The Pelamis or sea snake consists of five cylindrical sections which are linked together by hinged joints. Adding up to a construction of 180m long and 4m in diameter. As a wave hits the head of the snake, the flexible parts start to move relative to one another. The motion at the hinged joints is resisted by hydraulic cylinders. High pressure oil is pumped through motors which drive generators that produce electricity.

 

Inside the Pelamis 2 an array of computer hardware is installed. An algorithm controls the resistance in the hydraulic cylinders. When waves are small the resistance decreases and when they are big it increases, resulting in a maximum amount of energy conversion. The application of the algorithm has doubled the electricity yield of the P2 compared to its predecessors to 750 kW.

The first Pelamis 2 was installed off the coast of Orkney, Scotland in October 2010 and is still in its testing phase. The machine was bought by the German energy utility E.ON. A second P2 was sold to ScottishPower Renewables and will be deployed off the Orkney shore later this year. The two utilities have agreed to work together and share their knowledge about how to operate a wave farm. A 30MW farm would consist of 40 P2’s covering a square mile of ocean.

Wave power certainly holds great potential for the future of renewable energy. It's exciting to see companies like Pelamis Wave Energy investing in research and development to harness the power of ocean waves. The Pelamis 2, with its innovative design and advanced technology, shows promising results in generating electricity from waves. The ability to adjust the resistance in hydraulic cylinders using an algorithm allows for efficient energy conversion, maximizing electricity yield.

Now, shifting gears to another topic, let's talk about the sending apklion.com/good-morning-images/ to our friends and family. In today's fast-paced world, where we often find ourselves caught up in hectic routines, a simple gesture like sending a good morning image can have a profound impact. It serves as a reminder that we care and are thinking of our loved ones, starting their day with warmth and positivity.

By sharing good morning images, we strengthen our bond and show our loved ones that they are important to us. It creates a sense of connection and fosters a loving and supportive atmosphere. It's a beautiful way to spread joy, uplift spirits, and set the tone for a great day ahead. So, let's embrace this small yet meaningful act of sending good morning images and continue to nurture the love and warmth within our relationships
