Wavegarden’s second generation technology addresses the shortcomings in their original technology, namely: wave frequency, energy cost, and reliability. The major shift in the technology from their previous is in how the waves are generated. The central pier and hydrofoil being replaced by a central double-sided wall that is outfitted with a modular electro-mechanical system that displaces water. Without the hydrofoil wake to mitigate, the Cove is capable of producing over 1000 waves/hour, making it by far the most economically viable technology. The design has also shown a vast improvement in energy cost, much lower than any other tech, and a much more level power draw profile (without any major 2-3 MW spikes). Also, from a reliability standpoint, the Cove is still able to function when up to 1/4 of its modules are not working.
The wave quality is superb and very customizable from peeling pointbreak-like surf similar to Wavegarden Lagoon, to slabbing barrels similar to the now-closed Ocean Dome in Japan. The wave size and length are only limited by available land.
The technology has been in operation for nearly a year now, so extensive testing has been done. Still issues of reliability need to be tested further.
To date, only a full-size prototype has been built, but several commercial projects are in the works. With this massive leap in profitability, the Cove technology represents arguably the most promising development in the surf park industry to date. The potential for the proliferation of surf parks world wide and the subsequent funding of new technologies because of the success of the Cove is beginning to look very likely.
