Devices that collect water from the atmospheric air using condensation are well-known. They operate in a manner very similar to that of a dehumidifier: air is passed through a cooled coil, making water to condense. This is the most common technology in use. Here, we present a device that can collect a large amount of water (more than 1m3/s) from the atmospheric air using gravitational condensation. Another novelty of this device is that it consumes little electricity. In addition, the new technology of this device leads to a new concept of pump, the Gravitational Pump, which can be used to pump water at very low cost from aquifers, rivers, lakes, etc., and also to supply the high pressure (100atm or more) needed to push seawater through the semipermeable membrane, in the desalinization process known as reverse osmosis.
