# Aquatic Floating Gardens Physalia Provides Filtered Waters and Green Spaces By Rose Nazarali | Published 2010-01-06 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/physalia References: [ecofriend.org](http://www.ecofriend.org/entry/physalia-a-positive-energy-amphibious-garden-to-clean-european-waterways/) & [vincentllebaut.org](http://vincent.callebaut.org/) Physalia is a system designed by Vincent Callebaut Architects that is supposed to help provide European countries with more clean drinking water. Physalia is a [self-sustaining floating garden](https://www.trendhunter.com/trends/living-sphere) that, according to EcoFriend, “is designed to [harvest renewable energy](https://www.trendhunter.com/trends/floating-solar-still) to make the prototype a positive energy one, where it can generate more energy that it consumes.” The Physalia is also able to take waste from the water and filter it into clean drinking water that also feeds its rooftop plants. ## Trend Insights (Trend Hunter) - Score: 4.3/10 - Popularity: 81% | Activity: 40% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Key Themes Behind This Trend - **Self-sustaining Floating Gardens:** Opportunity for designing floating gardens that harvest renewable energy, filter waste and provide green spaces. - **Renewable Energy Harvesting Systems:** Opportunity for developing energy systems that can generate more power than their consumption. - **Water Filtration Technologies:** Opportunity for creating efficient water filtration systems that could provide clean drinking water and maintain aquatic ecosystems. ### Where This Applies - **Architecture & Design:** Opportunity for architects and designers to create self-sustaining green spaces for cities with limited land area. - **Renewable Energy:** Opportunity for renewable energy companies to provide energy solutions for remote areas and developing countries. - **Water Treatment & Management:** Opportunity for companies to innovate in providing clean drinking water and maintaining aquatic ecosystems amidst increasing industrial and environmental pollution. ## Related on Trend Hunter - [Lotus-Inspired Floating Water Purifiers](https://www.trendhunter.com/trends/floatis.md) - [Recycled Plastic Floating Homes](https://www.trendhunter.com/trends/mast.md) - [Artfully Made Floating Plazas](https://www.trendhunter.com/trends/aquapraa.md) - [Floating Amazon Plaza](https://www.trendhunter.com/trends/the-aquapraa.md) - [Floating Cultural Plazas](https://www.trendhunter.com/trends/aquapraca.md) - [Autonomous Aquafarming Robots](https://www.trendhunter.com/trends/cultivation-robot.md) - [Digital Marine Habitats](https://www.trendhunter.com/trends/nereid-marine-habitat.md) - [Urban Food Ecosystems](https://www.trendhunter.com/trends/living-sphere.md) - [Floral Architecture Floating Restaurants](https://www.trendhunter.com/trends/nelumbo.md)
