Temperatures this past summer reached as high as 45°C, if my car thermostat can be relied upon. While the arrival of much gentler weather is happiness to some, it is actually a slight disappointment to our team of researchers at the Petroleum Institute in Abu Dhabi. We need all the humidity we can get in our effort to come up with an energy-saving, electricity-free way to collect water from the air around us.
Humidity is nothing but the presence of water vapour in the atmosphere. It is sometimes uncomfortable if humidity levels are high. Water vapour comes from a natural process where water evaporates from different bodies of water, including sea, rivers, wells, shallow water and so on. When water evaporates it remains, in vapour phase in the atmosphere and it leads to a formation of clouds in the sky.
We experience and confirm the existence of water vapour in the atmosphere when we enjoy a cold bottle of something refreshing to quench our summer thirst. On the outside surface of this bottle, a good quantity of water condenses from vapour (which is already in the atmosphere) to liquid. The process is also clear to us if we turn on a window air conditioner and observe the quantity of water collecting at the back side of this AC. In both cases, water condenses from the atmosphere because of changes in temperature (from hot to cold) that lead to the change in phase from vapour to liquid. Achieving a lower temperature than the atmosphere requires energy. In the case of a cold bottle, it has to be kept in a refrigerator, which runs on electricity. The same is also true for the ACs, which also run on electricity. In both cases electrical energy must be supplied to condense water.
The fact that you can collect water from air is fascinating. However, if the method implied requires direct electrical energy, then the concept has already been exhausted in the technical and scientific literature. But if we can collect water without direct use of electrical energy, then it is of paramount importance that such direction is to be pursued. “Pursuing” is what we started doing two years ago in the Petroleum Institute.
What we have developed is an apparatus which is constructed from smart materials that have unique attributes. These smart materials have the ability to collect water when the atmospheric temperature is low and it rejects the collected water when the temperature is high. During nighttime, the temperature in Abu Dhabi is low compared to daytime. Hence, the apparatus we are developing is capable of collecting water at night and it expels water during the day when the sun rises and the temperature increases. The collected water is allowed to accumulate in a container and then can be used immediately for agricultural uses and with further treatment can be adapted for human uses.
The advantage of our apparatus is that it can be used in any place as long as there is humidity. It doesn’t require any extensive infrastructure because it works without electrical energy. The apparatus can be fabricated in different sizes from bottle size to car size, depending on the need. We have submitted patent applications for this invention to the World Intellectual Property Organization and United States patent and Trademark office. Currently, we are working feverishly in our laboratories to test the performance of these smart materials and the apparatus. Hopefully, we can bring this invention closer to reality in the near future.
The higher the humidity the more water we can collect. When you enjoy the next cool bottle, remember that the condensed water on it is as precious to the UAE as an oasis is precious to a nomad in need of shelter, shade and water.

Four reasons global stock markets are falling right now
There are many factors worrying investors right now and triggering a rush out of stock markets. Here are four of the biggest:
1. Rising US interest rates
The US Federal Reserve has increased interest rates three times this year in a bid to prevent its buoyant economy from overheating. They now stand at between 2 and 2.25 per cent and markets are pencilling in three more rises next year.
Kim Catechis, manager of the Legg Mason Martin Currie Global Emerging Markets Fund, says US inflation is rising and the Fed will continue to raise rates in 2019. “With inflationary pressures growing, an increasing number of corporates are guiding profitability expectations downwards for 2018 and 2019, citing the negative impact of rising costs.”
At the same time as rates are rising, central bankers in the US and Europe have been ending quantitative easing, bringing the era of cheap money to an end.
2. Stronger dollar
High US rates have driven up the value of the dollar and bond yields, and this is putting pressure on emerging market countries that took advantage of low interest rates to run up trillions in dollar-denominated debt. They have also suffered capital outflows as international investors have switched to the US, driving markets lower. Omar Negyal, portfolio manager of the JP Morgan Global Emerging Markets Income Trust, says this looks like a buying opportunity. “Despite short-term volatility we remain positive about long-term prospects and profitability for emerging markets.”
3. Global trade war
Ritu Vohora, investment director at fund manager M&G, says markets fear that US President Donald Trump’s spat with China will escalate into a full-blown global trade war, with both sides suffering. “The US economy is robust enough to absorb higher input costs now, but this may not be the case as tariffs escalate. However, with a host of factors hitting investor sentiment, this is becoming a stock picker’s market.”
4. Eurozone uncertainty
Europe faces two challenges right now in the shape of Brexit and the new populist government in eurozone member Italy.
Chris Beauchamp, chief market analyst at IG, which has offices in Dubai, says the stand-off between between Rome and Brussels threatens to become much more serious. "As with Brexit, neither side appears willing to step back from the edge, threatening more trouble down the line.”
The European economy may also be slowing, Mr Beauchamp warns. “A four-year low in eurozone manufacturing confidence highlights the fact that producers see a bumpy road ahead, with US-EU trade talks remaining a major question-mark for exporters.”
