It is my pleasure to inform that on Sunday, 27.09.2015, in Anexartiti Protovoulia in Thermaikos we have fully assembled and installed (inside the office big window) first prototype of a passive air heating solar panel, developed by Morris Dovey, who was here in August to teach us how to build it. The panel is working very well despite the fact that it doesn’t exactly follow the design specification at http://www.iedu.com/Solar/Panels/index.html. I will probably provide temperature measurements (outside, inside-input, inside-output), as soon as I put my hand on 2-3 thermometers.



And here’s the photostory:

This is the beginning of huge project introducing open technology for Greek communities. If you want to watch it (and perhaps to help us) — stay tuned.

We now aim on

– preparing a measurement set (sensors to monitor temperature and airflow) which would tell us what is ACTUAL heating power of the device.

– building another prototype based on more standard parts (tailor-made metal fins accounted for half of the cost at the first time)

– building a lightweight version, for presentations in various places.

– building an externally mounted version, for the houses not having South-facing windows.

Each of these goals needs 200-300 Euro to be pooled. So if you want to help us with money, parts or tools, please contact me for arrangements.

For the full-blown account of this project, see Morris Dovey‘s page.
