Abstract: An energy capture ventilation device is provided. The energy ventilation device includes a housing. The housing is formed by a number of side walls to define an interior volume. A duct is connected to the housing, to interface with a ventilation system. A vent is placed on the housing opposite of the duct. At least one generator is attached to the duct. The generator includes a turbine and is connected to a battery. When the turbine is rotated, power is supplied to the battery.

Abstract: A rotating bathroom floor mat device is disclosed, comprising a series of carpeted, rotatable assemblies, a heating means and a gear and pulley mechanism. The device provides a wide, rectangular enclosure that allows a user to step directly onto its flat, upper surface, which is comprised of a series of adjoining, rotatable surfaces. Control buttons along one side of the upper service are operable via depression of a user's foot, which in turn activates a heating means and fan convection means to rapidly dry a user's feet and remove moisture from the carpeted assemblies. The assemblies are triangular sections that allow three distinct working surfaces. Once a first user has dried his or her feet, the assemblies are rotated to reveal a fresh, dry surface for a second user. The heating and convection means dries the previously used, moist carpet while in a stowed position.
