Abstract
An engine comprising an enclosure having an open top surface and an interior volume partially filled with a fluid in both vapor and liquid phase and a biased diaphragm covering the open top surface of the enclosure. The biased diaphragm is movable between a concave and a convex states, thereby enabling instantaneous changing of the interior volume between a first lesser volume and a second greater volume respectively. A thrust tube extends laterally from the enclosure providing fluid communication between the interior volume and an external body of the fluid. A heater causes the fluid in the enclosure to produce a greater volume of the vapor phase. A thermal sensor enables the fluid to be heated and cooled cyclically thereby causing inflow and outflow of the fluid driving a thruster or a turbine.
Claims5
An engine apparatus comprising:
- an enclosure having an interior volume partially filled with a fluid in both vapor and liquid phase;
- a biased diaphragm functions as one wall of the enclosure and is movable between one of a concave and a convex states, thereby enabling instantaneous changing of the interior volume between a first lesser volume and a second greater volume respectively;
- a thrust tube extending laterally from the enclosure providing fluid communication between the interior volume and an external fluid body of the fluid;
- and a means for heating the fluid in the enclosure cyclically to cause fluctuation of the diaphragm between the concave and convex states.
A method of operating an engine comprising the steps of:
- filling an enclosure with a fluid in both vapor and liquid phase;
- sealing the enclosure with a biased diaphragm, the biased diaphragm movable between one of a concave and a convex states, thereby enabling instantaneous changing of the interior volume of the enclosure between a first lesser volume and a second greater volume respectively;
- providing a thrust tube extending from the enclosure and providing fluid communication between the interior volume and an external fluid body;
- providing a means for heating the fluid in the enclosure;
- switching the heating means on when the temperature in the fluid is below a selected temperature thereby raising the vapor pressure in the vapor phase of the fluid;
- moving the diaphragm to the convex state when the vapor pressure is increased thereby sucking fluid into the enclosure thereby cooling the fluid in the enclosure and reducing the vapor pressure;
- moving the diaphragm to the concave state thereby driving fluid out of the enclosure when the vapor pressure is reduced;
- and repeating the change of the diaphragm from concave to convex cyclically.
