This is my basic micro ORC concept to be developed as DIY project.


ORC converts low temperature heat to mechanical work for generatig elecricity.
The simple ORC consists from 5 basic components: see below.

E-HX - Evaporator heatexchanger
TEX - Turboexpander
G - Generator
C-HX - Condenser heatexchanger
P - Pump

I have got more information regarding working temperature and pressure of that ORC.
See link below.

Micro turbo-expander designed for 65Watt output power.
Turbo expander is one of the most dificult part in the cycle itself. It needs to be preperlz designed and produce with high precission. See a micro turbo expander designed for 65Watt output power here.
Here are some interesting information which I am following about turbines design.

Is this some sort of advertising or are you intending to build a turbine based generator?

I am going to show how the design part of this project is going forward and discuss regarding the solution.

A picture below shows concept of counterflow heatexchanger.
This represents basic design of evaporator and condenser. Also is designed to simple make it.

Regardign the cycle efficiency there is important the overal thermodynamical cycle eff. It is affected by components efficiency, but main affect have the working temperature and working fluid. See the picture of cycle working properties below.
These are properties of my micro scale size demo cycle. Click on the 3D view here (http://www.microgenerationconcepts.com/), to see the proposed components and design.
