Dubai now has a vertical axis wind turbine, a first for the emirate, installed on the campus of the Rochester Institute of Technology’s branch in the emirate.
The installation of the 10-kilowatt turbine is the result of a collaboration between RIT Dubai and Italy-based Ecolibri, a renewables company with a focus on wind energy.
Vertical axis wind turbines, unlike the conventional horizontal axis wind turbines, have the ability to capture wind from any direction.
The turbines, which depending on the design can sometimes resemble a giant egg-beater, are also known as Darrieus model turbines, a reference to the French aeronautical engineer and inventor Georges Jean Marie Darrieus, who pioneered the idea in the 1930s.
Because they're generally quieter and don't require high wind speeds, vertical axis wind turbines are quickly gaining popularity in cities where larger, horizontal axis versions aren’t as practical.
"We did some research over the course of a year and found the wind in the area was good enough to power the wind turbine," said Prof Ghalib Kahwaji, director of RIT Dubai’s Sustainability and Energy Centre.
He emphasised that although the turbine was not connected to the overall power grid, it will be used to power RIT Dubai's sustainability park.
"It's equipped with a smart microgrid," he said. "It will be a small community integrating the wind turbine and solar power systems."
As part of the collaboration with Ecolibri, the sustainability park also contains a geodesic dome that can be used as a meeting area or classroom complete with electricity.
Installation of RIT Dubai's vertical wind turbine in December came only months after the UAE announced plans to launch its first wind programme in an effort to achieve net-zero emissions by 2050.
The UAE's wind farm programme, announced in October, is expected to power more than 23,000 homes a year, displacing 120,000 tonnes of carbon dioxide, Abu Dhabi clean energy company Masdar said.
Innovations in climate technology have made wind energy more feasible in the UAE, where wind speeds were previously deemed inadequate to generate enough power.
Mr Kahwaji said RIT Dubai's wind and sustainability research started two years ago.
"It feels good," he said. "Our efforts complement each other and we're pioneering research in this area."
The vision of RIT Dubai's Sustainability Centre, according to Mr Kahwaji, is for the programme to be a leading enabler of smart sustainability research in the UAE.
"That's what we're doing with wind and geothermal research and applications," he said. "We don't want to keep our work entrapped by research, we want to go out into society and apply our ideas."
The wind turbine is the latest addition to RIT Dubai's campus in the Silicon Oasis district. In 2022, Newsweek magazine rated the futuristic innovation centre, which resembles the core of a quantum microchip, as one of the 10 quirkiest college campus designs in the world.
RIT Dubai was established in 2008 and is a satellite campus of the Rochester Institute of Technology in New York, which was founded in 1829.

TOUCH RULES
Touch is derived from rugby league. Teams consist of up to 14 players with a maximum of six on the field at any time.
Teams can make as many substitutions as they want during the 40 minute matches.
Similar to rugby league, the attacking team has six attempts - or touches - before possession changes over.
A touch is any contact between the player with the ball and a defender, and must be with minimum force.
After a touch the player performs a “roll-ball” - similar to the play-the-ball in league - stepping over or rolling the ball between the feet.
At the roll-ball, the defenders have to retreat a minimum of five metres.
A touchdown is scored when an attacking player places the ball on or over the score-line.

What is blockchain?
Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.
The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.
Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.
However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.
Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.

Financial considerations before buying a property
Buyers should try to pay as much in cash as possible for a property, limiting the mortgage value to as little as they can afford. This means they not only pay less in interest but their monthly costs are also reduced. Ideally, the monthly mortgage payment should not exceed 20 per cent of the purchaser’s total household income, says Carol Glynn, founder of Conscious Finance Coaching.
“If it’s a rental property, plan for the property to have periods when it does not have a tenant. Ensure you have enough cash set aside to pay the mortgage and other costs during these periods, ideally at least six months,” she says.
Also, shop around for the best mortgage interest rate. Understand the terms and conditions, especially what happens after any introductory periods, Ms Glynn adds.
Using a good mortgage broker is worth the investment to obtain the best rate available for a buyer’s needs and circumstances. A good mortgage broker will help the buyer understand the terms and conditions of the mortgage and make the purchasing process efficient and easier.
