# Self-Sufficient Underwater Architecture HO2 Scraper Harvests Renewable Energy to Grow Food By Katie Cordrey | Published 2010-08-08 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/ho2-scraper References: [thedesignblog.org](http://www.thedesignblog.org/entry/self-sufficient-underwater-skyscraper-harvests-renewable-energy-to-grow-its-own-food/) & [evolo.us](http://www.evolo.us/competition/water-scraper-underwater-architecture/) Sarly Adre Bin Sarkum of Malaysia has designed the HO2 scraper, a self-sufficient [underwater wavescraper](https://www.trendhunter.com/trends/darpa-1) that harvests renewable energy from the sea, then uses it to grow food. Underwater architecture is particularly interesting to those concerned with [rising sea levels](https://www.trendhunter.com/trends/lift-house) due to global warming. The HO2 scraper harvests wave, wind and solar power and uses [aquaculture and hydroponic food production](https://www.trendhunter.com/trends/living-on-groundwater) technologies to grow food underwater. **Implications** - The last few years have seen an increase in the importance of environmentally friendly devices and products. One of the best ways a company can engender good will is by creating products that explicitly exhort consumers to catch up with them in purchasing sustainable products and living a Green lifestyle. ## Trend Insights (Trend Hunter) - Score: 5.4/10 - Popularity: 82% | Activity: 72% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, South America, Europe, Asia, Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What Makes This Trend Stand Out - **Underwater Architecture:** Designing self-sufficient structures underwater presents opportunities for harnessing renewable energy and sustainable food production. - **Renewable Energy Harvesting:** Using wave, wind, and solar power to generate energy underwater offers innovative solutions for sustainable living. - **Aquaculture and Hydroponics:** Combining aquaculture and hydroponic technologies allows for underwater cultivation of food, addressing future challenges of food production. ### Sectors Adopting This - **Architecture and Construction:** The architecture and construction industry can explore the design and development of self-sufficient underwater structures for various purposes. - **Renewable Energy:** The renewable energy industry can focus on developing technologies to efficiently harvest wave, wind, and solar power from the sea. - **Agriculture and Food Production:** The agriculture and food production industry can innovate methods of cultivating food underwater using aquaculture and hydroponics. ## Related on Trend Hunter - [Digital Marine Habitats](https://www.trendhunter.com/trends/nereid-marine-habitat.md) - [Urban Food Ecosystems](https://www.trendhunter.com/trends/living-sphere.md) - [Autonomous Aquafarming Robots](https://www.trendhunter.com/trends/cultivation-robot.md) - [Rain-Collecting Skyscrapers](https://www.trendhunter.com/trends/bpas-architects.md) - [Water-Powered Family Residences](https://www.trendhunter.com/trends/breach-house.md) - [Personal Aquatic Scooter Units](https://www.trendhunter.com/trends/underwater-scooter-concept.md) - [Bio-Cement Oceanic Structures](https://www.trendhunter.com/trends/reef-rocket.md) - [Resilient Concrete Sea Walls](https://www.trendhunter.com/trends/breathing-sea-wall.md) - [Aquarium Cleaning Tool Scrapers](https://www.trendhunter.com/trends/rollingreef.md)
