Abstract: A self-extinguishing candle is provided which, in a preferred configuration, comprises a candle having a wick with a series of alternating combustion and non-combustion zones. In use, the wick will burn through the combustion zone, and will be extinguished on reaching the non-combustion zone. The non-combustion zone is preferably provided by a physical or chemical means, and the candle can be re-lit by removal of the non-combustion means. A safer candle is provided that will self-extinguish on a regular basis.

Abstract: A vertical axis wind turbine wherein the blades of the rotor section of the wind turbine comprise at least sections wherein the blades have a non-linear configuration in the “z” axis. In a preferred embodiment, the blades of the rotor section have a linear trailing edge with a non-linear, and preferably helical, surface configuration. This particular design allows the blades to provide both a rotational force and a positive or negative lift component. Further, the blades define an open area in the center of the rotor section through which air flow can pass in order to create a vertical vortex of air. As such, a more efficient vertical axis wind turbine provided.
