Solar Steam Cooling

I had a crazy idea some time ago, about using a small, cheap solar collector to produce superheated steam (and my father and I did build the device described up to this point and it works fine) and then use a venturi to trade the velocity of escaping steam for volume of air moved (inject steam via a fine pitot into the opening of a pipe so that outside air is pulled into the pipe) [ed: better yet, use the steam jet to create a vacumn in the exit pipe on the hot side and avoid the temp increase of the steam on the inlet side] and then direct that into a Hilsch Vortex to produce hot/cool air for house A/C.

I would guess that back pressure at the entrance to the Vortex would limit the incoming air volume excessively or that the increased temp of the air (due to the steam injection) would negate any cooling gains on the part of the Vortex or some such other problem would prevent it from working. BUT, I haven't been able to find any proof that the idea is unworkable. Please help put my mind at rest or send me a million dollars to finance a prototype. (GRIN)

The nice thing would be: No moving parts other than the water and the air and the collector (sun tracking), automatically starts when the sun heats it up, super low construction cost, almost zero operating cost (only maintenance and water supply). The potential inefficiencies are offset by the low (zero) cost of water and sunlight.
