The system can function in air with 20% humidity or less. But these 1,000 liter a day machines are not small, at around shipping container size.

It’s a Fremen wind trap.

The article explains that the system doesn’t use power or any type of refrigerant, instead it uses a new type of material with large surface areas in a small package to capture/condense the water out of the air while utlizing wind and the sun to help accomplish its goal.

I would agree that up until now the only viable technology was a dehumidifier which takes great amounts of fossil fuel energy, but this isn’t the case here.

In other words, a dehumidifier.

There’s no such thing as a free lunch. To condense water fro air, you need a lot of energy, considering how little humidity there is in a desert, it would be better to just use that energy to bring the watter from somewhere else rather than running the dehumidifier.

What pisses me off, is that we’re willing to build thousands of kilometres of pipe to transport dinossaur juice but not watter.

Fuck this capitalist system.

  This system does not require a power source.

  A passive water harvester based on MOF-303 has been designed and configured to achieve the highest efficiency among passive designs. A water harvesting capacity of 285 g H~2~O per kilogram of MOF-303 per day with only ambient sunlight and no power or other energy input was achieved. The MOF cartridge design and the condenser surface treatments were key features in achieving high water harvesting efficiency especially when tested in the field (Death Valley National Park).
  
  From the paper.
  
  It’d be really nice if people actually read the article instead of just assuming they already know everything.

Giant heat pump?

You can’t fool the laws of thermodynamics.

  No need to fool the laws of thermodynamics, it’s enough to fool investors
