# Auto-Charging Fans The Self-Generator Can Spin with the Power of its Prior Mechanical Energy By Amelia Roblin | Published 2014-10-01 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/selfgenerator References: [yankodesign](http://www.yankodesign.com/2014/09/29/the-power-of-a-fan/) & [yankodesign](http://www.yankodesign.com/2014/09/29/the-power-of-a-fan/) When you stop to consider the Self-Generator concept, it makes a great deal of sense that such a machine could easily be made more economical. Julia Zhu and Tab Chao developed a proposal for an extremely efficient ceiling fan that can actually make use of the energy stored from its own [repetitive motion](https://www.trendhunter.com/trends/mag-drive). As you switch off the ventilator, the dissipated kinetic energy can be recovered, stored, and converted into electricity. This can be used the next time you switch on the Self-Generator. The two-blade design of the fan keeps the appliance streamlined and lightweight, and capable of spinning faster with less power required. Every time you use it, you're saving a significant amount of electricity, helping you achieve [greener cooling](https://www.trendhunter.com/trends/home-cooling) on even the hottest days. ## Trend Insights (Trend Hunter) - Score: 5.1/10 - Popularity: 65% | Activity: 80% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - 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's Driving This Trend - **Self-generating Fans:** Opportunity for the development of more efficient and economical ceiling fans that make use of their own kinetic energy to generate electricity for future use. - **Energy-storing Technology:** Opportunity for the advancement of technology that can recover, store and convert dissipated kinetic energy into electricity for various applications. - **Green Cooling Solutions:** Opportunity for the development of eco-friendly appliances that make use of sustainable energy sources to reduce electricity consumption and promote sustainability. ### Who This Affects Most - **Appliance Manufacturing:** Manufacturers can integrate self-generating technology in the production of ceiling fans to offer more energy-efficient and eco-friendly options to consumers. - **Renewable Energy:** Renewable energy companies can explore the potential for energy-storing technology in the creation of sustainable energy storage solutions for various industries. - **Home and Building Automation:** Automation companies can incorporate self-generating fans in their smart home systems to offer energy-saving solutions for consumers and contribute to overall sustainability efforts. ## Related on Trend Hunter - [Self-Covering Cooling Fans](https://www.trendhunter.com/trends/clofan.md) - [Smart Ceiling Fan Concepts](https://www.trendhunter.com/trends/fanpro.md) - [Multipurpose Living Space Fans](https://www.trendhunter.com/trends/air-circulation-fan.md) - [Regenerative Cycling Equipment](https://www.trendhunter.com/trends/energy-keeper.md) - [Lamp-Equipped Fan Designs](https://www.trendhunter.com/trends/abode-gale-fan.md) - [Two-in-One Rechargeable Desk Accessories](https://www.trendhunter.com/trends/appliance-concept.md) - [Jet Engine-Inspired Fans](https://www.trendhunter.com/trends/tello-zet.md) - [Rectangular Bladeless Fans](https://www.trendhunter.com/trends/rectangular-bladeless-fans.md) - [Self-Charging E-Bikes](https://www.trendhunter.com/trends/vello-bike-design.md)
