This device is designed and constructed at Massachusetts Institute of Technology (MIT) which can extract water from air using only sunlight, this is being considered to be the best innovation of the year.
It can extract up to 2.8 liters water in 12 hours even if the humidity is as low as 20%. The prototype have been constructed and tested in MIT and the team was successful in extracting water and considered it to be successful.
University of California, Berkeley was also involved in the project which constructed the special metal which was used in the project. The designer and the team in MIT is hopeful that they will be able to change some material and design so that the extraction will be further increased.
It is not the first time that such device has been constructed, but it is the only designed device which uses sunlight.
