Hi, I'm having a bit of a problem, and I'm not sure where to put the question. So here's a picture Sorry about the picture, Tank B should really be half-full of water and steam. Ignore the turbine part. I'm trying to create a distillation device and the basic idea I had was to have a boiler that would use a steam generator to heat the boiler. Then add a turbine to the steam generator that would power a dynamo that would power another pump within the cooling tank for the condenser. A self contained system as far as energy is concerned. Both tank systems were originally closed, so there was no effective heat exchange between the two systems, other than from the distillation of the vapours from the still itself. The steam generator tank was hot, the condenser tank was cool. I had some weird idea that if I created a closed system, by creating different pressure between the two systems I could effectively have two different temperatures, i.e., maintaining a hotter temperature for the steam generator and cooler temperature for the condenser tank. Thus it would remain a kind of closed system with very few parts. The question is, all else being equal, will the temperature remain constant in the above system once a certain equilibrium is reached? or, will Tank A be hotter than Tank B? What are the conditions for that equilbrium? What is the relationship between Heat, Pressure and Temperature? I'm sorry if this seems obvious, I just honestly don't even know where to begin with a question like this, as there never seems to be one obvious answer.
