Check out the link to Science Daily's story of an invention by some PhD students at the Israeli Technion Institute. The upside-down pyramid is able to draw the water (i.e., dew) out of the air. (I would make a joke about pyramid power, but that would be too easy.)
As a person who is interested in water, water policy, water management, water ecology, etc., this is a potentially groundbreaking moment, especially if it can help mitigate drinking water problems in arid regions of the world. However, one has to wonder if this might have any sort of compounding/confounding impact on the local water cycle if used en masse.
I found out about this when I was looking at the following blog: Climate of Our Future
