Worried by drought? Well, stop it. Put it this way. Have you ever noticed that when you put an ice-filled glass outside on a humid day, water starts appearing on the outside? This is humidity from the air condensing on the glass. There are countless gallons of water wisping around the air even in the driest of climates, let alone those cities that make you drown helplessly in sweat like a hairless ape.
An Israeli Company appropriately named EWA (Extraction of Water from Air) has engineered a creation that sucks out gallons of water a day at 85% energy efficiency. This means most of the energy used in the cycle is reused in the next cycle, making it extremely efficient.
Since the condensation of high energy water vapor into lower energy liquid water means the extra energy has to go somewhere, it’s simply reused in the form of heat to power the machine itself. Hence the energy efficiency.
EWA’s earnings have skyrocketing from a mere $100,000 when it started to a predicted thousand times more at $100 million this year.
Their CEO Dr. Etan Bar explains, “One cubic kilometer of air contains 10 to 40 thousand tons of water — enough to supply at least 100 thousand people with all their water needs, or enough ‘safe’ drinking water for two million.” EWA’s device will produce anywhere from a few hundred liters of water per day to 1,000 cubic meters of water in a single plant.
We’re waiting…and in the mean time, we’ll take quick showers.
