    Abstract: This Stirling machine comprises a transfer piston (6, 6a) and a moving part (14) of a generator or of an electric motor, the transfer piston (6, 6a) periodically displacing a working gas between an expansion chamber (VE) and a compression chamber (Vc) which chambers are respectively associated with two working faces of the transfer piston (6, 6a) of which the cross-sectional area ratio ac/aE is >0.35 so that its displacement along an axis X oriented towards the expansion volume (VE) generates an in-phase working gas pressure component Px that opposes the displacement of the piston (6, 6a), so that all of the mechanical energy produced is transmitted to the moving part (14). This machine comprises a resonant second piston (10) coupled to the transfer piston (6, 6a) by a quantity of energy that is proportional to the pressure component Px.

    Abstract: The apparatus includes a housing, a compression chamber disposed in the housing and having at least a first interface operable to vary a volume of the compression chamber, an expansion chamber disposed in the housing and having a second interface operable to vary a volume of at least the expansion chamber, and a thermal regenerator in fluid communication with each of the compression chamber and the expansion chamber. The thermal regenerator is operable to alternatively receive thermal energy from gas flowing in a first direction through the regenerator and to deliver the thermal energy to gas flowing in a direction opposite to the first direction through the regenerator. The compression chamber, the expansion chamber, and the regenerator together define a working volume for containing a pressurized working gas. Each of the first and second interfaces are configured for reciprocating motion in a direction aligned with a transducer axis, the reciprocating motion being operable to cause a periodic exchange of working gas between the expansion and the compression chambers. In one aspect, at least one of the first and second interfaces includes a resilient diaphragm, and a cylindrical tube spring coupled between the diaphragm and the housing, the tube spring being configured to elastically deform in a direction generally aligned with the transducer axis in response to forces imparted on the tube spring by the diaphragm to cause the at least one of the first and second interfaces to have a desired natural frequency. In another aspect the apparatus includes a first heat exchanger in communication with the expansion chamber, a second heat exchanger in communication with the compression chamber, the thermal regenerator is disposed between the first and second heat exchangers, and each of the first and second heat exchangers are peripherally disposed within the housing with respect to the transducer axis and configured to receive working gas flowing to or from the respective chambers and to redirect the working gas flow through the regenerator.

    Abstract: A method to store energy, the method comprising: (b) providing a phase change material, having a melting point of at least 500° C., in a container; (c) heating the phase change material to cause at least a portion thereof to melt and so store heat therein; (d) storing the phase change material for a period of time being at least one minute; (e) using at least a portion of heat from the phase change material as a power source; (e) moving the container and the phase change material from a first location to a second location, the first and second locations being spaced apart by at least 10 metres. Embodiments of the invention may be used for a variety of purposes, such as for vehicle propulsion, oil well stimulation and recovery of crude oil from sunken tankers. A vehicle may be moved to a location proximate to where the power source is required which is more convenient and indeed allows steam to be supplied in areas which where hitherto not possible. For certain embodiments the power source produced is used to propel a vehicle comprising the power source. Certain embodiments use a Stirling engine whilst others generate a steam source. In preferred embodiments steam is recovered after use as the power source and preferably reheated as per step (e).
