They want to harness energy from waves using a fleet of ships. The fleet would replace expensive transmission cables currently used to transfer electricity from offshore power generators to the mainland could ultimately be done away with. Typically, these cables fetch a salty price — often more than $500,000 for about
.62 miles." You can download a (rather primitive) visualization of the idea here. In terms of cost: "The project could potentially produce electricity at $0.15 per kilowatt hour — far cheaper than the cost of current wave technology, which falls anywhere from $0.30 to $0.65 per kilowatt hour."
