Warka Water promises to harness safe drinking water from the air

As water shortage is a serious issue in many parts of the world, a means of cheaply harnessing safe drinking water from thin air could be a real lifesaver. Italy’s Architecture and Vision is developing an off-grid bamboo tower called Warka Water that promises just that: the firm says it could collect an annual average of up to 100 liters of water per day.
Once completed, Warka Water will rise to a height of 10 m (33 ft), weigh 60 kg (132 lb), and be secured to the ground with eight guide ropes. The tower consists of a lightweight woven bamboo structure, while an inner plastic mesh retains water droplets from passing fog, which fall into a collector and a large tank. Any rainwater and overnight dew also collects in the tank.
Warka Water will sport a canopy that offers shade to people drawing the collected water, and a series of rotating mirrors which Architecture and Vision says will be sufficient to keep birds away. No electricity is required for any part of the passive water-harnessing process, and the firm says the bamboo structure will take six people four days to construct. On-site assembly should take four people just three hours, without the need for cranes or any other building machinery.
