# Wave Power-Harnessing Trawlers This Old Fishing Trawler Now Harvests Wave Power By Rahul Kalvapalle | Published 2015-02-12 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/fishing-trawler References: [gizmag](http://www.gizmag.com/fishing-boat-wave-power/35995/) & [gemini.no](http://gemini.no/en/2014/04/one-of-830-scientists-behind-the-climate-report/) An old Norwegian fishing trawler has been given a new lease of life as a [wave power-harnessing power plant](https://www.trendhunter.com/trends/efficient-energy-harvesting). Anchored off-shore in the Stadthavet region, this trawler is part of a broader effort to convert [large, purpose-built vessels](https://www.trendhunter.com/trends/electric-boat-model) into wave power harnessing monsters. The vessel makes use of an existing system dubbed the 'fluctuating water column'. This system utilizes four vertical chambers installed in a bow, which surrounding sea water can flow into and out of. Each of these chambers is capped by a [turbine situated on the deck](https://www.trendhunter.com/trends/hydrokinetic-river-power) of the boat. As waves collide with the vessel, they flow up into the chambers, causing water levels to rise. This increases air pressure in the upper section of the chamber, driving the turbine and generating electricity. This is a fantastic example of how old and seemingly useless things can be repurposed and given a new lease of life, in this case as eco-friendly power generators. ## Trend Insights (Trend Hunter) - Score: 5.3/10 - Popularity: 78% | Activity: 74% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Why This Trend Is Growing - **Wave Power-harnessing Trawlers:** Repurposing old fishing trawlers to generate wave power through fluctuating water column systems. - **Conversion of Purpose-built Vessels:** Transforming purpose-built vessels into wave power-harnessing monsters with innovative systems. - **Eco-friendly Power Generation:** Harnessing the power of waves to generate electricity and reduce environmental impact. ### Industries Being Reshaped - **Renewable Energy:** The renewable energy industry can explore opportunities to repurpose old vessels for wave power generation. - **Maritime:** The maritime industry can innovate by converting purpose-built vessels into wave power-harnessing systems. - **Sustainable Power Generation:** The sustainable power generation industry can benefit from the wave power-harnessing technology to reduce carbon footprint. ## Related on Trend Hunter - [Battery-Packed Wind Farm Ships](https://www.trendhunter.com/trends/powerx.md) - [Energy-Hauling Battery Tankers](https://www.trendhunter.com/trends/battery-tanker.md) - [Floating Turbine Wind Farms](https://www.trendhunter.com/trends/petrofac-and-seawind-ocean-technology.md) - [Wind-Powered Cargo Ships](https://www.trendhunter.com/trends/windpowered-cargo-ship.md) - [Floating Wind Platforms](https://www.trendhunter.com/trends/wind-platform.md) - [AI-Powered Sail Systems](https://www.trendhunter.com/trends/sail-system.md) - [Single-Blade Offshore Wind Turbines](https://www.trendhunter.com/trends/singleblade-offshore-wind-turbine.md) - [Mast-Mounted Wind Generators](https://www.trendhunter.com/trends/grain-blanc.md) - [Hydrokinetic River Turbines](https://www.trendhunter.com/trends/hydrokinetic-river-power.md)
