Well before air conditioning and oscillating fans kept us cool in the hot summer months, 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 3,980 yen (£23) 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 up 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]
