Thanks for amending the sketches, I'm travelling at the moment and don't have access to a ruler let alone a scanner. Thanks for comments above, I'll read and absorb when I get back,

Thanks for reply, goal would be free air conditioning and refrigeration. The steam injector pumps cold water into a high pressure boiler with no work input other than heat. The heat comes from burning fossil fuels My query is whether the same principle could be applied in a closed system using...

Thank you for your reply. Appreciate your interest. The Giffard injector intrigues me because the ability to 'pump' water from atmospheric pressure into a high pressure boiler with no apparent power input seems counter-intuitive. Here are a couple of links with diagrams/descriptions of how it...

My early working years were spent in fluid flow instrumentation, venturi tubes, measurement of flow through vortex shedding etc. Eventually ended up in computers and electronics but now retired, and partly in an effort to keep up with my sons who both did science at university I have a renewed...

To get water into a pressurised steam engine boiler, an injector passes high pressure steam through a converging/diverging nozzle, sucking cold water in at the throat. The resulting steam/water mix is at a higher pressure, but lower temperature, and so is able to return to the boiler. Heat is...
