QuoteThe UniWave sea platform is an artificial blowhole that harvests energy from ocean waves. Independent analysts now predict it'll create some of the cheapest renewable energy on the market – and some of the most reliable and predictable, as well.
QuoteWSE's key innovation here is that one-way generation; other devices that harvest the same effect use bi-directional turbines, requiring the ability to reverse blade pitch or redirect the airflow. WSE says its design allows for far cheaper and simpler turbines, that should also last longer since they're not getting as much salt water splashed through them when a big wave hits. Indeed, all this device's moving parts are above the waterline, a fact that should help extend its service life as well as making it completely harmless to marine life.
Love it! Sounds fantastic.
Pretty innovative design there. I really like the idea of using the wave to create a vacuum instead of having the flow of water turn the turbine directly. Not only is it a lot less complicated, it is a lot more serviceable with the spinny bits above the water like that.
