# Battery-Charging Boomerangs The Boo Generates Electric Power While You Play By Rose Nazarali | Published 2009-08-24 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/the-boo References: [yankodesign](http://www.yankodesign.com/2009/08/24/boomerang-addicts-can-now-charge-batteries/) & [jiyounkim](http://www.jiyounkim.com/) The Boo is a fun, eco-friendly design that allows users to play while [charging up old batteries](https://www.trendhunter.com/trends/charger-2). Designed as a boomerang, The Boo can hold three [AAA batteries](https://www.trendhunter.com/trends/linogy) and charges them as the boomerang gets thrown back and forth. The Boo turns the rotary motion into electric energy. The outside of the [self-charging system](https://www.trendhunter.com/trends/power-bank-concept) is made from silicone to help protect against hard falls. The center of The Boo has a small display to indicate charge levels. ## Trend Insights (Trend Hunter) - Score: 2.2/10 - Popularity: 8% | Activity: 50% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What Makes This Trend Stand Out - **Eco-friendly Toys:** Opportunity for toy manufacturers to create more sustainable and enjoyable toys like The Boo that offer consumers a fun way to reduce their carbon footprint. - **Energy-harvesting Products:** Opportunity for companies to design and produce innovative products that capture and convert kinetic energy like The Boo, offering consumers a more efficient and sustainable power source. - **Smart Energy Storage:** Opportunity for energy storage companies to develop smart energy storage systems like The Boo, which can store and discharge electricity produced by kinetic energy for various applications. ### Sectors Adopting This - **Toy Industry:** Opportunity for toy manufacturers to incorporate sustainable designs and materials like The Boo to meet the growing demand for eco-friendly toys and games. - **Consumer Electronics Industry:** Opportunity for consumer electronics companies to develop innovative products that capture and convert kinetic energy into electricity, providing consumers with a more efficient way to power their devices. - **Energy Storage Industry:** Opportunity for energy storage companies to explore the potential of kinetic energy storage systems like The Boo, which offer cost-effective and reliable energy storage solutions for various industries. ## Related on Trend Hunter - [Retro Gaming Chargers](https://www.trendhunter.com/trends/mobile-boy.md) - [Solar-Powered Oral Care Devices](https://www.trendhunter.com/trends/quip-solar-battery-charger.md) - [Energy-Generating Soccer Balls](https://www.trendhunter.com/trends/energy-generating-soccer-ball.md) - [Two-Part Charging Devices](https://www.trendhunter.com/trends/sparkee.md) - [Radio Wave-Powered Remotes](https://www.trendhunter.com/trends/samsung-eco-remote.md) - [Three-in-One Gaming Console Batteries](https://www.trendhunter.com/trends/remotta-enerjoy.md) - [Sustainable Rechargeable Batteries](https://www.trendhunter.com/trends/paleblue-usbc-cells.md) - [Self-Charging E-Bikes](https://www.trendhunter.com/trends/vello-bike-design.md) - [Battery Health Chargers](https://www.trendhunter.com/trends/linogy.md)
