Solar Water Capturing Device

Problem
Many developing countries in the Middle East and Africa are experiencing water shortage problems. The amounts of water vapor that can be found and potentially captured from the air are equal to about 10% of fresh water found in lakes on Earth. Most of the countries in question rely on importing water and aid from other word organizations. Furthermore, those areas experience low humidity which restricts the use of current technology due to their low efficiency.

Solution
A research team at MIT has come up with a design for a device that can capture water vapor at an average rate of 2.8 liters daily at relative humidity levels as low as 20%. The design is based on “porous metal-organic framework-801” that utilizes adsorption properties of the metal and organic material. The frame absorbs water and then the device uses the heat from the sun to release the water into a storage device. This means that no additional heat or energy is required to operate the device. The design is still in its early stage and further research and development are needed to make sure of its efficiency and reliability.

Stakeholders

  • Potential investors
  • Scientists and institution working on the research
  • Manufacturers of metal-organic material
  • People living in areas with water shortages

Next Steps
Since the technology is still in development, MIT and other investors should back the project for further development. The device is still a prototype and requires additional filtration system and an improved collection system for water particulates that form on the surface of the device. Advertise the technology and shift focus to countries in need of new freshwater resources to help fund the manufacturing process of the device and start initial testing.

Comment on “Hybrid Wind Power Generating & Fish Farming System

Although I like the idea of integrating different technologies and ideas and finding more efficient uses of spaces, there are many debates growing on whether these can be called “sustainable.” There are many issues with fish farms:

  • They disturb other fish habitats in the area
  • Inconsistent water currents and circulation can result in water with high health risks
  • Generally, they acquire a bad image in the eyes of the public vs. wild fishing
  • Risk of fish “escapes”

Maybe the technology can be modified so that the energy generated can somehow try to fix or minimize some of the issues listed above.
