You can’t miss three things on top of pretty much every household rooftop; passive solar hot water heater, water storage tank and satellite dish.
Solar water heater works amazingly well. Just within a few hours, it produces boiling hot water without any external power or moving parts.
Most Palestinian village turn on their municipal water supply a few times a month, so every household has some kind of holding tank. It has something to do with water rationing and leaking pipes, I believe.
Satellite dish is very common. Watching television is probably the top form of entertainment. Decoder box can be purchased for around NIS 150 (around $40) and it can receive 100’s of channels from all over the word, including Hollywood movies.
