Well before air conditioning and oscillating fans kept us cool, servants waving giant palm leaves was the ideal way to beat the heat. And Thanko's new USB-powered mechanical paper fan provides a similar experience, without requiring you to keep a professional fanner on staff.
For $US40, it can run off a laptop, or even a portable charger if you don't have access to a computer with USB ports. And it features multiple settings so you can crank the speed when the heat starts to get unbearable. It's also supposed to provide a gentler breeze than a fan, and that back and forth motion should help lull you to sleep, even when your bedroom feels like a sauna. [Thanko via Akihabara News]
