  • Gallery: Crestwing’s wave device taking shape

    first_img<br />(Photos by Crestwing)Danish wave energy developer Crestwing is making progress with the assembly of its Tordenskiold prototype wave energy device ahead of planned deployment this October.The Tordenskiold prototype device is 30 meters long, 7.5 meters wind with the height of 2.5 meters.It’s hull has been designed as that of a ship, while the device falls under the attenuator type of floating wave energy devices which operate parallel to the wave direction.These devices capture energy from the relative motion of their two arms as the wave passes them.According to Crestwing’s experimental data, the device is capable of producing around 1 million kWh of energy yearly energy extracted from the seas around Denmark. However, when the size of a wave is doubled, the energy in the wave is not merely doubled, but instead multiplied by a factor of 11, the Danish developer said.This means that Crestwing’s devices made for seas with waves twice as large as those found around Denmark, could reach an energy production of 11 million kW, Crestwing said on Indiegogo platform where it is currently running a crowdfunding campaign to support the demonstration of the Tordenskiold device.Crestwing is looking to raise €45,000 until October 20, 2017, when the campaign closes – having secured a little under €4,500 so far.The deployment of Tordenskiold prototype will serve to prove the survivability and power conversion technology of the device.last_img read more
