Wind-up remote control
Although it's a minor thing in the grand scheme of life, the remote losing power can be rather annoying. And despite our pressing the buttons harder, the channels eventually stop changing and we go looking for some fresh batteries. Now there's a battery-free remote control that eliminates the need to ever get off our butts ever again.
Online store Gizoo sells a universal remote control that uses wind-up power to charge itself. 30 twists is enough to power the device for a week.
