quote [ Last October, a UC Berkeley team headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight. ]
I hope they do beer next!

Wait - doesn't he have to go to Tashi station to pick up some power converters first?

He has to finish his chores before he can waste time with his friends.

Comparing with a data point from wikipedia for a more standard radiative condensor (in which the night dew condenses on a sheet of metal and just runs off rather than the extra step of a material to help capture moisture):
600m^2, 9000L/year... 40g per m^2 per day for the radiative condensor 100g per kg per day for the MOF according to their abstract. Looking at photos and their abstract it was 1.2kg of MOF in... call it 0.25m^2 so with extremely fuzzy math and ignoring their optimism of what it *could* collect in favor of current numbers, the MOF is about a factor of ten more efficient if we assume the conditions in India and Artizona are comparable (they probably aren't). |

I dunno, I have a strange feeling that this is gonna end up as big a debacle as that stupid self-filling bottle Kickstarter scam.

Some people are definitely over-reacting to it as a "water worries over, turn the deserts green!" thing, but the engineering itself is well grounded.
