I've incluced a picture below.
The collection chamber has its latch open when the air is being pumped out; this way the pressure in the collection chamber equals the pressure in the main chamber. It is only closed to remove the collection chamber and re-condense the steam into water under normal atmospheric conditions. It is then reattached, and the latch opened. The pump then only needs to suck the air that was in the collection chamber, a lot less then the work done by the turbine, (at least according to my calculations), thus still resulting in positive work being done. If any of you take physics, I'll try and include a PV diagram once I figure it out to better understand this process.
- Red lines are closable latches.
- The green line simply indicates the connection between the main chamber and the pump.
- The gold/orange thing towards the top is suppose to represent a magnet around a coil, while the black thing to the left of it is the best turbine I can draw :-P
