<p>An engine that utilises an external heat source, such as a solar energy, geothermal energy, waste heat, and/or burning of a fuel is provided. The engine has a piston located in a cylinder heated by the external heat source. Upon injection of a liquid into the heated cylinder, the liquid is vaporised, increasing pressure and providing power to the piston. Once the piston stroke is complete, the vapour is released and the piston returns to a position ready for injection again. In an embodiment, a cooling cylinder is provided which condenses the vapour into a liquid for injection into the heated cylinder. The engine may be utilised in conjunction with a steam turbine to convert water into steam, replacing a boiler while also providing additional work.</p> |
