Image Credit: Martin Holladay Plenty of sunshine. Almost every house in Crete has a solar hot water system. Because temperatures rarely drop below freezing, the hot water tanks are usually located outdoors. The water thermosyphons between the collectors and the tank, so no pump is needed.

You can put away your building science notebooks; this blog is simply a collection of photos from my recent vacation in Greece.
While the purpose of my trip was relaxation, I still managed to point my camera at a few construction sites and examples of renewable-energy equipment.
