Abstract: A magnetocaloric driving device is disclosed herein. The driving device comprises a magnet, an effective amount of a magnetocaloric material, and a counterpoise mechanism. The driving device generates useful mechanical energy by alternately cooling and heating the magnetocaloric material using an ambient heat sink proximate to a heat source. Useful heat sources include hot production fluids, such as hot water produced from a geothermal well. Useful heat sinks include cold production fluids, and cold ambient environments.

Abstract: A magnetocaloric valve is described. The valve is largely energetically self-sufficient and contains the following components: (a) a conduit defining a flow channel; (b) a flow channel blocking member; and (c) a driving device configured to move the flow channel blocking member into and out of the flow channel. The driving device has as key components a magnet, an effective amount of a magnetocaloric material, and a counterpoise mechanism. The driving device is powered by alternately cooling and heating the magnetocaloric material using an ambient heat sink and a production fluid heat source. Alternatively, the driving device is powered by alternately cooling and heating the magnetocaloric material using a production fluid heat sink and an ambient heat source. The valve may be kept open or closed by otherwise preventing movement of a movable component of the driving device, for example a shaft, by means of an electrically actuated shaft latch.
