Decimal point error correction for calculation of a MiniTurbine version of the
IAS Bladeless Turbine.

 
http://iaus.com/turbine.htm
 The calculations show that about 3.2 (STP)  liters/sec water vapor exitingthe rotor orifices will produce about 20 electrical watts at about 1.0% of 
theoretical efficiency (based on 2260 joule/gram contained in
the 0.72 grams of water vapor "propellent") compared to a Carnot efficiency of 1.5%
for the 5 K temperature difference.
 
Still not bad for a system that is scalable from milliwatts to megawatts.

 Using the flow calculator:

To see what 0.18 grams/sec water vapor at 330 K  (135 F @ 130 torr) exiting from
four 0.031 inch diameter tangential orifices on a 4 inch diameter
hollow rotor in an air-cooled condensing chamber at 325 K ( 125 F @ 100 torr)
spinning at 24,000 RPM ~ 400 ft/sec  would do as a generator.
 
The calculations show that about 3.2 (STP)  liters/sec water vapor exiting
the rotor orifices will produce about 20 electrical watts at 
about 12% efficiency compared to a Carnot efficiency of 15%.
 
But, I wouldn't bet the farm on it.  :-)
