This is not really a project that you can expect to design unless you have the education and experience behind you.

Try here.

Or here.

100 watts is just over 1/10 HP so it's going to have to be a very small turbine.

"we don hav any ideas about the material to used"
Do you mean the refridgerant?

It's no good asking a question like this unless you know your gas and the rest of the system and how much heat it needs to move.
