I'm a new user, and I hate to start out by deleting someone's page, but this idea doesn't work. The maximum pressure generated by a trombe is the proportional to the vertical height of the water column (P=\rho gh). The ability of pressurized air to lift water is limited by the same equation. The apparatus as drawn is equivalent to a siphon with the outlet held above the inlet---the water in the high tube will find the level of the inlet water.

I suggest that this be tested more times. Some testable models would let us know if there are other equations that should be being used. Please note that there is no violation of thermodynamic laws as long as the resulting power (a function of flow rate times pressure at the nozzle) is less than the producing power (a function of flow rate times pressure collection). A speculative note could be added to the page. --Lonny 17:50, 12 March 2013 (PDT)

  • Principle of Operation
-The action of compressing water and air doesn't cause them to separate

True, but the action of passing the water air bubble mixture horizontally through a separation chamber does. Brian Gaiatechnician 02:43, 20 August 2010 (UTC)Reply[reply]

  • Materials
-The use of a wrench for connections might be useful
  • Testing
-Since water is being forced into the tubing from a faucet,
 the pressure isn't due to the height of the tubing
-You need to justify your height measurement for the pumping
 tube since it bends back down to the water bottle
-The graphs seem to show that as the head increases, the flow decreases
  • Manometer Model
-With a manometer, the height of the two fluids will be the same if the pressure
 is the same.  It is incorrect to say that the volume of fluid in both straw would
 be the same since one straw could have a greater diameter.

I do not understand the manometer model or its point Gaiatechnician 18:44, 1 September 2010 (UTC)Reply[reply]
