Wave

Sweden's CorPower has announced "breakthrough" results from Atlantic ocean testing of its full-scale floating generators, which cleverly time their motions to amplify smaller waves while protecting themselves against dangerous storm conditions.

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Gigantic waves can seemingly come out of nowhere, threatening ships and oil rigs. Now, an AI system trained on centuries of data has been able to predict when these rogue waves will occur, revealing new insights into how they form.

With the aid of arms control technology and artificial intelligence, a team of scientists at Cardiff University's School of Mathematics has developed a method that uses underwater microphones to provide early warnings of potentially deadly tsunamis.

Much of the heat and carbon produced by humans is absorbed by the ocean. New research has shed light on the role that underwater waves play in moving that heat and carbon around our oceans, an important factor in predicting climate change.

Irish company OceanEnergy has already tested its oscillating water column generators at significant scale in Hawaii, and it's just signed on to a four-year project to test, validate and commercialize its biggest unit yet off Orkney, in Scotland.

The UniWave sea platform is an artificial blowhole that harvests energy from ocean waves. Independent analysis now predicts it'll create some of the cheapest renewable energy on the market – and some of the most reliable and predictable, as well.

A new class of elastic energy converters is emerging, with the ability to capture energy from a variety of different motions. The National Renewable Energy Laboratory is pushing to deploy them, first in a series of strange, bendy wave energy designs.

Sea Wave Energy Ltd has been working for more than a decade on an ultra-cheap floating wave energy device. With several prototypes tested, the company is promising capacities over 100 MW, with unheard-of energy cost figures under 1 cent per kWh. Hmm.

Wave Swell Energy's remarkable UniWave 200 is a sea platform that uses an artificial blowhole formation to create air pressure changes that drive a turbine and feed energy back to shore. After a year of testing, the company reports excellent results.

Researchers are reporting a record-setting new example of a phenomenon known as a rogue wave, with a four-story-tall behemoth that occurred off the coast of Canada confirmed as the most extreme ever measured.

Scientists have uncovered a new way tsunamis might be better predicted ahead of time, showing how the magnetic fields they generate can be detected before the massive, devastating waves make it to shore.
