# Underwater Kites 'Deep Green' Tidal Turbines Fly Under Ocean Surface By Katie Cordrey | Published 2010-05-10 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/deep-green-tidal-turbines References: [popsci](http://www.popsci.com/science/article/2010-05/sea-kites-could-harness-tidal-energy-future-power-plants) & [minesto](http://www.minesto.com/technology-4/deep-green-technology-37) ‘Deep Green’ tidal turbines look like underwater kites fly up from the ocean floor, producing power beneath the ocean surface. Turbines are individually attached to a wing and rudder, which is then tethered to the ocean floor by several hundred feet of cable. The Deep Green tethered kites are able to capture energy from [tidal currents](https://www.trendhunter.com/trends/tidal-flight) ten times faster than the speed of the current stream and can generate [500 kilowatts of power](https://www.trendhunter.com/trends/wind-turbine-generator). It’s impressive output for a device with a 40’ wingspan--a size much smaller than other tidal-energy designs. ## Trend Insights (Trend Hunter) - Score: 5.3/10 - Popularity: 56% | Activity: 96% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What's Driving This Trend - **Underwater Energy Generation:** Developing innovative methods to generate energy beneath the ocean surface using tidal turbines and underwater kites. - **Tethered Turbines:** Innovating on the use of tethered turbines for faster and more efficient energy capture from tidal currents. - **Compact Marine Energy Solutions:** Developing smaller marine energy solutions with impressive output for use in more areas and applications. ### Who This Affects Most - **Renewable Energy:** Exploring the use of underwater kites for harnessing tidal energy and other innovative methods for renewable energy generation. - **Marine Technology:** Integrating deep green tidal turbines and underwater kites into marine technology systems for sustainable energy generation. - **Infrastructure and Construction:** Incorporating underwater energy technologies into infrastructure and construction projects to reduce reliance on fossil fuels and improve sustainability. ## Related on Trend Hunter - [Floating Wind Platforms](https://www.trendhunter.com/trends/wind-platform.md) - [Hydrokinetic River Turbines](https://www.trendhunter.com/trends/hydrokinetic-river-power.md) - [Single-Blade Offshore Wind Turbines](https://www.trendhunter.com/trends/singleblade-offshore-wind-turbine.md) - [Eco Oceanic Energy Systems](https://www.trendhunter.com/trends/waveline-magnet-concept-design.md) - [Floating Turbine Wind Farms](https://www.trendhunter.com/trends/petrofac-and-seawind-ocean-technology.md) - [Mast-Mounted Wind Generators](https://www.trendhunter.com/trends/grain-blanc.md) - [Portable Wind Generators](https://www.trendhunter.com/trends/Portable-Wind-Generator.md) - [Honeycomb-Shaped Wind Turbines](https://www.trendhunter.com/trends/bladeless-wind-turbine-design.md) - [Underwater Jetpack Designs](https://www.trendhunter.com/trends/kikfin.md)
