The invention provides devices and methods for moving charged molecules into and out of tissue samples. This invention is particularly useful for removing endogenous heterogenous particles from tissue samples and for introducing exogenous charged molecules (e.g., antibodies, dyes) into tissue samples.

The invention relates to the field of magnetohydrodynamic generators, and more precisely to such a generator (10) comprising a working fluid flow passage (11) that is defined by a first wall (12) and a second wall (13), an ionizing device (14) for ionizing the working fluid, a pair of arms (15), each connecting together the first and second walls (12, 13) downstream from said ionizing device (14) so as to define, within the flow passage (11), a channel (16) between said arms (15) and said walls (12, 13), said channel (16) being arranged to be traversed by a portion of the working fluid after it has been ionized, a magnet for generating a magnetic field (B) oriented in a direction that is perpendicular to the flow of the working fluid through the channel (16) defined by the pair of arms (15) and said walls (12, 13), and at least one pair of electrodes (17), each of the electrodes (17) in each pair being arranged on a respective side of the channel (16) defined by the pair of arms (15) and said walls (12, 13), said electrodes (17) in each pair being spaced apart from each in a direction that is perpendicular to said magnetic field (B) and to the flow direction of the working fluid through the channel (16) defined by the pair of arms (15) and by said walls (12, 13).

Embodiments of an apparatus for generating electric power from flowing seawater are disclosed. Embodiments form fluid channels having magnetic fields through which seawater will flow. Electrodes are arranged with respect to the fluid channels and connected together such that electric power is generated as seawater flows through the channels.

An ion separating device comprising a stator cylinder with input and output ports, end caps, a rotor core, homopolar north poles, and homopolar south poles, is used to separate positive and negative ions in electrolyte introduced into the device. The resulting charged ionic solutions are stored in separate tanks. Energy recovery from the charged ionic solutions is accompanied by the release of gases thereby providing another process of producing hydrogen and oxygen.

An ion separator for a water pump is provided, comprising a stator cylinder with input and output ports, homopolar north poles, and homopolar south poles, a drive shaft, a rotor core, and seals. Salt water pumped through the ion separator water pumps is desalinated by alternatively flushing out the positive and negative ions at various points as the water flows through the proposed devices. Two pump configurations are presented for use in desalination of salt water.
