I continue to study various aspects of solar electricity production and passive solar heat, the efficiency each year increases so much; there is now solar window film, solar roof tiles, even solar paint!! This means that there are more and more ways to absorb the sunlight in order to transform it into electricity.
It may be that now that Michael has a great assistant, Yannis, we will be “filling in” all the walls next year and putting on the first layer of plaster, on all the unfinished walls. I am now thinking of building two “trombe” walls for passive heat, on the back and side of the upstairs.
The space to the upper right, the east facing back wall upstairs is where the trombe wall will go.
Notice the size of the banana?? Having someone there to water while we gone this fall made a huge difference. The little tree in the foreground is my acacia which has never really taken off, but hangs in there!
There is a link to more pictures at the end of the letter.
