UAE consider to build man-made mountain to increase rain fall

After the extraordinary success of the cloud seeding operations that saw a significant increment of the quantity of rain fell over the United Arab Emirates, it seems that the government is seriously considering the opportunity to build a man made mountain in a bit to improve rainfall.

The United Arab Emirates invested a significant amount of 558,000 USD in the 2015 alone within the Rain Enhancement Program initiative activated by the UAE Ministry of Presidential Affairs (MOPA) and run by the National Center of Meteorology & Seismology (NCMS). As reported by a local newspaper, the  Program provides grants to up to five innovative research and technology proposal over a three year period that are trying to find new ways to enhance rainfall in the Country.

“What we are looking at is basically evaluating the effects on weather through the type of mountain, how high it should be and how the slopes should be. We will have a report of the first phase this summer as an initial step”

Said  National Center for Atmospheric Research (NCAR) scientist and lead researcher Roelof Bruintjes to ArabianBusiness.

He further clarified that the NCAR received funds to provide a detailed modelling study evaluating the effects of building a mountain on the weather.

For those not really specialized in climatology and how the rain process works, humid and warm air moving towards the mountains will be forced by them to raise. While raising the air temperature drops (almost 6.5 Celsius per km for humid air) causing the condensation of the humidity and the creation of rain drops.

In order to do so, the mountain shall intercept the predominant air currents forcing them to release their water content before passing through.

“Building a mountain is not a simple thing. We are still busy finalizing assimilation, so we are doing a spread of all kinds of heights, widths and locations as we simultaneously look at the local climatology. If the project is too expensive, logically the project won’t go through, but this gives them (the Government) an idea of what kind of alternatives there are for the long-term future” Bruintjes said.

“If it goes through, the second phase would be to go to an engineering company and decide whether it is possible or not.”

 We have no other option but to wait the preliminary results.

Saudi Bin Ladin Group cuts 100,000 jobs

It has been recently filtered that the major Saudi Arabian construction company, Saudi Bin Ladin Group, has issued 77,000 final exit visas meaning it had terminated 77,000 foreign workers.

Rumors further says that the group is planning to lay off up to 17,000 Saudi nationals, bringing the total number of job cuts to almost 100,000, representing almost half of its workforce.

Contacted by a local newspaper the construction giant replied that “adjusting the size of our manpower is a normal routine especially whenever projects are completed or near completion. Most of the released jobs had initially been recruited for contracted projects with specific time frames and deliverables” as reported by news agency Reuters.

As a matter of fact, Binladin has been under pressure since September last year, when it was suspended from receiving new state contracts after one of its cranes collapsed into Mecca’s Grand Mosque during a dust storm, killing 107 people.

In addition, the company is suffering from low oil prices that have led to government spending cuts to curb a record budget deficit.

As reported by ArabianBusiness, rumors say that Saudi Binladin group owe local and international banks a total of about 30 billion USD.

Emaar’s new Tower at Dubai Creek Harbour unveiled

Finally it has been made official. Emaar Properties, one of the most appreciated developers in Dubai with several successful projects already completed like The Greens, Dubai Mall, Burj Khalifa and the whole Downtown neighborhood, is going to beat his own records.  After having developed the current tallest building in the world, it has recently unveiled what could be the world’s new tallest tower.

Even though the official height still has to be disclosed, Emaar management has confirmed that it will be a “notch taller than Burj Khalifa” that with its 828 meters mesmerizes thousands and thousands of visitors every day.

The tower is expected to cost 1 billion USD and will face competition from the 1,000 meter high Kingdom Tower in Jeddah (KSA), currently under construction, for the “tallest building in the world” title.

The tower was designed by Spanish architect Santiago Calatrava, who has designed masterpieces of architecture like the Museum of Tomorrow in Rio de Janeiro or Athen’s Olympic Sports Complex, and was inspired by the Islamic minaret structure as well as a lily bud.

Emaar New Creek Tower

“Inspired by a Nation. designed for the World” is Emaar motto for the challenging Project – Photos from Emaar website.

The tower is going to be built as part of a wider Project knows as Dubai Creek Harbour, a mixed use development located in proximity to Ras al Khor Wildlife Sanctuary and its flamingos and many species of waterbirds.

The aim of the 6 sq km development was very well explained by Mohamed Alabbar, chairman of Emaar Properties:

“With The Tower, we are delivering a compelling destination that will add long-term economic value to Dubai and the UAE. It will also position Dubai Creek Harbour as one of the most desired residential, leisure and touristic attractions, providing visitors and residents with a modern, luxurious and sustainable environment in which to live, work, learn and entertain.”

The Tower and the Project are presented in the recently released videos prepared by Emaar.

 

The sky is the limit.

Revealed: Dubai Metro “Route 2020″extension works to begin soon

It is official, after months of statements, reassurances and postponements, we are finally there. Work on Route 2020, the 15km extension of Dubai Metro’s Red Line, will begin in the next few months, Abdul Mohsin Ibrahim Younus, CEO of RTA’s Rail Agency revealed at Middle East Rail Conference on Tuesday.

“Work on Route 2020 will begin immediately after we award the tender, which will be within the next few months. The extension will be ready before Expo 2020”

The Route 2020 will pass through Discovery Gardens and Dubai Investment Park on its way to the venue of Expo 2020. Heading from Nakheel Harbour and Tower station, the route serve seven additional stations, 2 of which will be underground as also reported by Dubai Metro website. The newly served communities are inhabited by about 240,000 people and the project will not be only beneficial for those visiting the Expo 2020 area but also for the many residents living in the outskirts of the city. The journey from Dubai Marina area to the site of Expo will take 16 minutes and from Dubai International Airport (DXB) to Expo will take about 1 hour.

But this is not the only news about the metro expansion. The red line is foreseen to be further extended to Dubai World Central – Al Maktoum Airport (DWC) and the green line will increase of almost 21 km from Al Jaddaf Station to Dubai Academic City passing by Ras Al Khor, International City and Silicon Oasis.

According to Mr.Younus, also the Dubai Tram will be extended by 5 km due to its popularity and success. Phase 2 of the Tram will serve iconic landmarks like Burj Al Arab and Madinat Jumeirah.

For those regularly using the Metro, it is evident of its success. Any given time of the day or the night, the metro is busy with people commuting to work or simply going to any of the well known landmarks like Mall of Emirates, Dubai Mall, Gold & Diamond Park and so on. I am personally not really convinced by the performance of the Tram but I noticed that it ranks in the top attractions to see in Dubai in many popular holidays websites.

Construction news: more than 390 billion USD projects ongoing in Dubai

The total value of projects under construction in Dubai equates to $53.6 billion, with a further $337.2 billion in the planning stage.  These are significant amounts of investment for most mature economies, but for an emerging market such as Dubai, they are extraordinary figures which provide evidence of Dubai’s ambition to diversify its economy away from oil-centered revenues. In this way we can summarize the new report “The Dubai Construction Pulse” published by Deloitte and MEED Projects, which analyses the construction market across a range of sectors.

Analyzing the data provided in the report, it is evident that the majority of the construction projects currently ongoing in the Emirate are related to residential and hospitality sectors with a 60% of the total value involved while 65% of the planned projects fall within the mixed use developments, most probably because of the EXPO 2020’s requirements.

Dubai Construction Projects Status

“Despite regional security concerns and wider macro-economic turbulence, Dubai continues at pace with significant project awards in Q1 2016, including the Palm Gateway Towers, Phase II of the Atlantis Resort and Dubai Creek Harbour to name but three”, said Ben Hughes, director at Deloitte Corporate Finance Limited, regulated by the Dubai International Financial Center.

Previously stalled projects have been resurrected, but new project awards have reduced since 2014-2015 as a result of regional economic uncertainty

The conclusions of the report are particularly interesting and are here below summirized.

“The current concerns relating to low oil prices and diminished market sentiment has clearly had a short term impact. Whilst the ongoing geo-political factors equally have profound effects, the fact that many Governments across the region, not least the Government of Dubai, are continuing to spend on infrastructure and other strategic developments suggests that they foresee the oil price issue and political turmoil as a temporary one.

[…] The mere action of building a project and expecting the demand to be there no longer applies, as the fundamental cost basis for these projects remains volatile and competitive. Focusing on factors such as affordability, differentiation and quality are going to be increasingly important factors, and it is hoped that such considerations will ultimately underpin the rationale for conceiving projects.

Simply constructing the tallest or most unique project no longer provides the impact it once did, so diversifying the offer by promoting a world class standard appears to be the mantra moving forwards.

[…] What is interesting is the connectedness of Dubai as an increasingly “smart city”, and […]  Dubai may even mature to the extent that it could surpass some of the more established cities across the world, such as London, Paris or New York, in terms of its level of sophistication and dedication to sustainability, smart city principles and ultimately success in delivering projects that are demand driven and profitable.”

Other than on “The Dubai Construction Pulse” website by Deloitte, the matter has been analyzed and reported by well done articles published on SaudiGazzette and Gulf Construction Online.

UAE to be Solar Thermodynamic Energy’s World Leader by using sand to generate electricity

Concentrated Solar Power (CSP) uses mirrors to reflect heat from the sun to one point, most typically the tow of a tower filler with a fluid (usually molten salt) capable of storing heat for prolonged periods then used to produce electricity.

An alternative to the central tower is represented by curved mirrors concentrating the sun light in a suitable pipe that runs all the way from/to the storage accumulating heat while running in the plant.

In both cases, the molted salts are heated up to 600 degree Celsius and transferred in a hot storage.

The fluid so heated is used to produce high temperature/high pressure steam that is used to generate electricity by evolving in a steam turbine.

The main benefit of this technology is that energy is easily stored and can be used at night when the source of heat (the sun) is absent. However, the popular photovoltaic modules are currently more cost effective and therefore preferred over the concentrated solar power plants.

But now the situation can drastically change.

Masdar Institute of Science and Technology’s scientists, indeed, have published a breakthrough research into more efficient solar power plants by using sand as vector fluid to transport and store energy.

Named “Sandstock”, the research published at the Solar Power and Chemical Energy Systems Conference in South Africa in December 2015, showed sand can withstand temperatures of up to 1,000°C and the higher you can push the temperature, the more efficient the plant will be in generating electricity.

The approach chosen by the researchers at Masdar Institute completely eliminates the most expensive components of the traditional CSP, the molten fluid and the pump system, by substituting it with sand and gravity. The design concept, which is inspired by a traditional sand hourglass, features a ‘cold tank,’ where sand is initially stored – before flowing into a ‘hot tank,’ located directly underneath. The cold tank will take the form of a hollow cylinder, designed to allow the concentrated solar flux to penetrate an empty central cylinder part.

“Sand is really always a drawback in this country but in this project we wanted to use it as an advantage because it can withstand very high temperature, and of course it is very cheap here,” said Dr Nicolas Calvet, assistant professor of mechanical and materials engineering, and guide for the research project, as also reported by The National.

“Photovoltaic is more popular because of more than 40 years of research, and the Chinese entering the market and driving prices down,” Dr Calvet said.

“If you want to make CSP more competitive you must significantly reduce the cost.”

The main costs for CSP are the reflective material, and whatever is used for heat transfer and storage. Dr Calvet and his students are using sand for the last two steps at almost no cost.

“When you build a CSP plant you need to import usually several thousand tonnes of molten salts from Chile,” he said.

“With this concept you can just build your plant in the desert and you don’t have to bring any other material, you have it on site.”

Dr Behjat Al Yousuf, interim provost at the Masdar Institute of Science and Technology, said: “The research success of the Sandstock project illustrates the strength of our research and its local relevance.
