Cordless Battery-Free Kinetic Doorbell


Never worry about having to replace fiddly wireless doorbell batteries. This ingenious cordless doorbell uses no batteries at all. Instead, the bell push works using natural, free energy. The simple act of pressing the button creates kinetic energy which converts to a voltage pulse, powering the internal RF transmitter and sending a signal to the plug-in mains receiver.
