Abstract
Abstract A device is described for transducing heat-kinetic power into electrical power using a charged aerosol, which flows through a sheet conversion space having emitting and exciter arrays to charge and form droplets at the entrance plane and a collector array to discharge the droplets at the exit plane and to supply electrical power to load; which results in increased efficiency with greater output power and current at a smaller voltage.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
In a power conversion device utilizing a charged aerosol as a transducer, an emitter array comprising a plurality of charge emitters to form and charge the charged aerosol, a conversion space to convert the heat kinetic power of the charged aerosol to electric power, an exciter electrode for the emitters, said emitters per unit area exceeding the number of exciter electrodes per unit area by a minimum point density of at least five points per exciter electrode, and a collector array for discharging the charged aerosol and transmitting the electric power to an external load.
Claim 2
Dependent Claim
95 words
In a power conversion device utilizing a charged aerosol as a transducer, an emitter array comprising a plurality of charge emitters to form and charge the charged aerosol, a conversion space to convert the heat kinetic power of the charged aerosol to electric power, an exciter electrode for the emitters, said emitters per unit area exceeding the number of exciter electrodes per unit area by a minimum point density of at least five points per exciter electrode, and a collector array for discharging the charged aerosol and transmitting the electric power to an external load.
Claim 3
Dependent Claim
122 words
A device according to claim 1 in which the emitter array per exciter electrode exceeds the minimum point density by one or more orders of magnitude and in which the distance between the exciter electrode and the emitters is less than 2mm whereby the potential difference between emitter and exciter electrodes is less than 1,000 volts, wherein the minimum point density is n a2 (U/L) where a2 is the array constant and is of the order of 0.5, U is the velocity of the charged aerosol in meters per second, and L is the length of the conversion space in meters. (whereby ions are emitted to form a charged aerosol in the conversion space at maximum current density at incipient spark breakdown.)
Claim 4
Dependent Claim
49 words
A device according to claim 2 in which the conversion space length is less than 2 millimeters and in which the arrays exceed 1 point per mm2 employing less than 100 volts potential difference between emitter and the exciter electrode, providing output electric power at less than 10,000 volts.
Claim 5
Dependent Claim
21 words
A device according to claim 1 in which a mixture condensation process is employed to charge and form the charged aerosol.
Claim 6
Dependent Claim
18 words
A device according to claim 4 in which superheated vapor is emitted from orifices between the point emitters.
Claim 7
Dependent Claim
17 words
A device according to claim 1 in which the emitter exciter and collector arrays comprise linear arrays.
Claim 8
Dependent Claim
36 words
A device according to claim 1 in which the conversion space is in the form of a large area, thin sheet in which the ratio of diameter to conversion length is at least five to one.
Claim 9
Dependent Claim
36 words
A device according to claim 7 in which the said large area and short length conversion space is bounded by an array of nozzle elements, a planar array of emitters and a planar array of collectors.
