#POWER FROM THE SEA - An Irish firm has landed a contract to provide a wave device for a new offshore energy test site in Cornwall, Siliconrepublic reports.

Ocean Energy, which is based in Cork, will deploy its first full-scale wave energy device at Wave Hub - described as an 'electrical socket' for testing wave power technology - off Hayle in north Cornwall by the end of the year.

The technology behind the buoy-type device, which will cost €9 million, has been developed over the past three years via a quarter-scale prototype in Galway Bay.

Using the principle of the oscillating water column, the device works by channeling water through a submerged chamber that forces air through a turbine above the surface.

The full-scale unit is expected to generate enough electricity to power as many as 1,200 homes.

Waszp sailing

The Waszp project was conceived in 2010 by Andrew McDougall, designer of the world-beating Mach 2 foiling Moth. 

The Waszp was created as a strict one-design foiler, where, as the class says “the true test when raced is between crews and not boats and equipment”.

The objective of the class rules is to ensure that this concept is maintained. Keeping possible modifications to a minimum ensures fair racing across the fleet, helps to reduce the overall cost to the sailor and reduces the amount of time in the workshop. 

The popularity of the WASZP has proven that the boat and the concept work. In October 2021, 1237 boats had been sold to over 45 countries. 

The top speed recorded on the foiling dinghy is 26.7 knots. 

60-95kgs+ is a weight range competitive across varied conditions with rigs knowns as ‘8.2’ and ‘6.9’.

The cost of a Moth dinghy in Europe is €14,400 inc VAT + shipping according to the manufacturers in October 2021.
