Cooling has still to be solved. I have the control circuit pretty much built and the controller can activate the necessary relay. I'm pretty sure I'm going to use 12V computer fans - I have a box of them I bought years ago. The problem I have with using the windows is the wind we have where I live. Should it suddenly get windy it would rip the windows off, this is why it's built behind a shed; the shed is in the path of the prevailing winds.

The cost to operate is zero :-). You can't see them in the photos but there are solar panels on the roof that are connected to the batteries. These supply enough power to run everything. They were salvaged from a house I was working on when the owners had a grid supply connected.
