Abstract: The vertical wind turbine and system generally comprises a rotor assembly having a plurality of blades, a fixed central spindle having a central axis for supporting rotation of the rotor assembly, a blade adjustment mechanism assembly for adjusting the blade angle of attack throughout rotation of the rotor assembly, and a support framework for supporting the rotor assembly at an elevated position in order to gain access to a sustained source of wind. The wind turbine may be operably coupled with a power electric generator or other device which transfers mechanical energy into electrical energy as a combined system.

Abstract: An alarm system for indicating the removal of a plug from a receptacle including an alarm adapted to actuate upon the receipt of an activation signal. Further provided is an actuation mechanism coupled between a power source and the alarm having a first orientation when a conventional plug is properly inserted within associated prong apertures of the electrical receptacle for precluding the transmission of the activation signal. The actuation mechanism further has a second orientation when a conventional plug is removed from the associated prong apertures of the electrical receptacle for allowing the transmission of the activation signal.
