Is Condensed Water the Salvation for Developing Countries?
Yesterday, I wrote about the new DH9 from DewPointe, one of the cool eco-innovations to be showcased at West Coast Green October 1-3 in San Francisco. The DH9 is capable of extracting water vapor from the air and converting it to (very) pure drinking water, at a rate of about 6.5 gallons per day. The technology is inspiring, in that this is a free-standing water manufacturer, needing no water supply, and conjures up images of moisture farms and growing forests where once there was desert. Indeed, even in 30% relative humidity, which is akin to some of the driest deserts in the world, the DH9 can produce 4 gallons of water per day from the air.
The big drawbacks are the cost ($1600 retail price) and the need for electricity. While standing, the DH9 uses 80 Watts, and while actively filtering, it uses 500.
Researchers in Stuttgart, however, have solved one of those two problems: their system is completely based on renewable, on-site energy.
