The prototype Eco-Twinkle-Light is recharged with human energy when a hand-crank is turned to deliver a recharge. Rotating the handle transfers causes energy to be delivered to [battery storage](https://www.trendhunter.com/trends/regenbox-1) to light the device. The Eco-Twinkle-Light is also a pencil-sharpener. After all, the crank is already there, why not get a little extra function from it? **Implications** - In the last few ytears, there has been a movement towards [eco-friendly products](https://www.trendhunter.com/trends/sustainable-energy-solutions). One of the best ways a company can engender goodwill from the media and environmentally conscious consumers is by investing in practical Green products.
