A magnetic fluid drive device for driving a magnetic fluid having temperature sensitivity in accordance with heat reception, the magnetic fluid drive device includes: a heat receiver having a flow channel through which the magnetic fluid flows, to receive heat; a magnet member disposed outside the flow channel to generate a magnetic field; and a drive mechanism that changes a position of the magnet member with respect to the heat receiver from a first position that is adjacent to the heat receiver with the magnet member applying the magnetic field to the magnetic fluid in the flow channel.

A fluid propulsion system configured to propel an ambient fluid through a propulsion channel. To do so, the present invention includes a hollow main body having a propulsion channel extending therethrough. The main body includes a base structure, a flexible bladder attached thereto, and a fluid (e.g., liquid, gas, or plasma) enclosed within the bladder. The present invention further includes a field source that produces an electromagnetic or magnetic field. The bladder and/or the enclosed fluid is configured to respond to the electromagnetic or magnetic field. Movement of the bladder in response to energization of the field sources alters a degree of occlusion of the propulsion channel. Energizing sequential field sources causes the occluded section of the bladder to propel the ambient fluid through the propulsion channel creating a reactionary force to propel the fluid propulsion system in the opposite direction.
