Wave-Sub Unveiled for Sea-Based Testing

Welsh company Marine Power Systems has completed work on its prototype WaveSub wave energy generator.
Wave-Sub Unveiled for Sea-Based Testing

The WaveSub will now be towed to the FaBTest test site in Cornwall, England. Here MPS will demonstrate the WaveSub’s power-generation capacity across a broad range of sea conditions, the speed and cost-effective price at which it can be installed, its low maintenance costs and its survivability through the harshest of conditions.

“With nearly a decade of research and development invested in the WaveSub, we are now at a point where an affordable, scalable and reliable wave energy device is within our reach. The testing of the quarter-scale WaveSub at FaBTest represents a milestone for MPS – we are delighted to have reached this point in its development,” said Dr Gareth Stockman, Chief Executive Officer of Marine Power Systems.

The WaveSub operates by capturing wave energy around six miles from shore, utilizing the continual orbital motion of waves to drive a sophisticated power-take-off (PTO) system. The power is transferred to land via an undersea cable. At full-scale, a WaveSub device rated at 5 MW could power approximately 5,000 homes.

 Along with the environmental benefit of cutting CO2 emissions and helping to meet climate change targets globally, wave power could potentially provide jobs, energy resilience and economic benefits.

As it moves into this new phase of testing, MPS is launching an investment opportunity to enable it to move into the final stages of development before commercialization; the testing of a full-scale multi-MW WaveSub. With investment in place, MPS will be on track to begin installation of a grid connected wave farm by 2020.

I request you to see my videos for Power Generation with Ocean Waves at: 1). https://www.youtube.com/watch?v=pQpVmvnZ9sk 2).https://www.youtube.com/watch?v=jWAUfJC8uLM 3)https://www.youtube.com/watch?v=dC-MNSIzMjM These Videos were put up a few years back and my understanding of the Ocean Wave Energy was different at that time. In my first video, I have commented that Ocean Wave Energy is 100KWs per meter wave crest length, which may be seen only at very few locations, the world over. I request you to see, my Website www.powerindiatechnologies.com Ocean Wave Energy is highly Concentrated. It is said that an area of 10 miles X 10 miles of the Ocean surface, has enough energy to Power the entire State of California----- about 60,000 Mega Watts. https://www.youtube.com/watch?v=OUYvkXZC4bQ I developed two new technologies for Power Generation with Ocean Waves and patented them (Patent pending). I have my limitations, as my work is not State Sponsored. Because of my personal financial constraints, I could not test them in deep sea. My Technologies are: 1) Near Shore Technology. With this technology, it is possible to tap, the energy present in the waves, near to the coast, in depths of about three to five meters. Here the units, stand on the Ocean Floor. Hundreds or thousands of these units, can be placed, singly or in rows of two or more, and all the mechanical energy, that is tapped by the individual units, is brought to one point, to run a single large generator. This Technology is ideal, where Coastal erosion is a serious problem. Wave energy in uninhabited remote areas could be tapped, to feed the Grid. To put it in short, these units are the small bricks, that are placed in two or more rows, in a wall. These units when placed in a stretch of 300 meters X 30 meters, in depths of about three meters, could produce a few Mega Watts of power, that could power the surrounding coastal areas. 2) Deep Sea Technology. With this technology, it is possible to tap Ocean Wave Energy in deep seas, where depths of about 100 feet, to any extent are present. It is ideal to tap this energy, a few Kilometers from the shore, as transmission losses could be minimized. With this Technology, it is possible to run a single large generator of 100MWs or more. This Technology does not affect Fishing industry.The efficiency of the plant could be over 90%. Noise pollution could be Nil or Minimal compared to any other Technology. Marine life, is not affected, in any way. Ocean floor is not disturbed, what so ever with this Plant.
