Eco Factor: Hybrid energy humidifier with an integrated energy generator.
The Wool Ball Hybrid is the brainchild of designer Yuan Gu and has been conceptualized to make your living room more comfortable by keeping indoor air humid and clean. The concept humidifier works in two modes – standard and hybrid. When running in the standard mode, the humidifier works by getting its power from a conventional wall socket.
The products eco-friendly credentials pop in when the device is running in the hybrid mode. When running in the hybrid mode, the Wool Ball works by getting its power from an integrated battery, which is recharged when your pet uses it as a rolling toy. As the device rolls, it emits a sound while the generator inside recharges the battery.
