Designing ultra-efficient elevators to go faster and higher is only one of several challenges facing the builders of ever taller towers. As they reach for the sky, other obstacles include:
Wind
Turbulence increases at higher altitudes, exerting huge pressure on buildings. Super-tall towers already sway to compensate. But they can only move slightly before people inside the building start to feel the movement. Engineers are constantly working to reduce wind resistance. Water tanks also help dampen movement.
Plumbing
Moving water and sewage around super-tall towers creates a variety of challenges. Behind the sheer volume of pipes, nobody wants to hear water rushing through the building. Designs typically include curves and various holding tanks to slow the flow.
Cement
Most of the super-tall buildings in the Gulf are built with cement. But getting cement to great heights quickly and efficiently is not easy. Among other records, Dubai's Burj Khalifa, the tallest building in the world, set a new standard for pumping cement to altitude.
Electrical
Tall buildings require kilometres of complicated wiring. The length of the systems is not necessarily a problem, but the bulk becomes a critical issue. Space must be found to run the wires and pipes and that takes away from usable space, which is at a premium in super-tall towers.
Fire safety
The 9/11 attacks on the World Trade Center towers provided vivid evidence of the horrors involved in trying to emergency evacuate very tall buildings. The tragedy brought safety to the forefront and helped to spur a rethink of strategies. Typically people are told to avoid lifts in an emergency. But new systems call for elevators to bring people to safe areas on different floors and to additional escape routes.
Finances
Buildings grow more expensive as they rise. But developers have compensated by building larger projects on the ground floors and charging more for land and projects around super-tall towers.

Studying addiction
This month, Dubai Medical College launched the Middle East’s first master's programme in addiction science.
Together with the Erada Centre for Treatment and Rehabilitation, the college offers a two-year master’s course as well as a one-year diploma in the same subject.
The move was announced earlier this year and is part of a new drive to combat drug abuse and increase the region’s capacity for treating drug addiction.

How to play the stock market recovery in 2021?
If you are looking to build your long-term wealth in 2021 and beyond, the stock market is still the best place to do it as equities powered on despite the pandemic.
Investing in individual stocks is not for everyone and most private investors should stick to mutual funds and ETFs, but there are some thrilling opportunities for those who understand the risks.
Peter Garnry, head of equity strategy at Saxo Bank, says the 20 best-performing US and European stocks have delivered an average return year-to-date of 148 per cent, measured in local currency terms.
Online marketplace Etsy was the best performer with a return of 330.6 per cent, followed by communications software company Sinch (315.4 per cent), online supermarket HelloFresh (232.8 per cent) and fuel cells specialist NEL (191.7 per cent).
Mr Garnry says digital companies benefited from the lockdown, while green energy firms flew as efforts to combat climate change were ramped up, helped in part by the European Union’s green deal.
Electric car company Tesla would be on the list if it had been part of the S&P 500 Index, but it only joined on December 21. “Tesla has become one of the most valuable companies in the world this year as demand for electric vehicles has grown dramatically,” Mr Garnry says.
By contrast, the 20 worst-performing European stocks fell 54 per cent on average, with European banks hit by the economic fallout from the pandemic, while cruise liners and airline stocks suffered due to travel restrictions.
As demand for energy fell, the oil and gas industry had a tough year, too.
Mr Garnry says the biggest story this year was the “absolute crunch” in so-called value stocks, companies that trade at low valuations compared to their earnings and growth potential.
He says they are “heavily tilted towards financials, miners, energy, utilities and industrials, which have all been hit hard by the Covid-19 pandemic”. “The last year saw these cheap stocks become cheaper and expensive stocks have become more expensive.”
This has triggered excited talk about the “great value rotation” but Mr Garnry remains sceptical. “We need to see a breakout of interest rates combined with higher inflation before we join the crowd.”
Always remember that past performance is not a guarantee of future returns. Last year’s winners often turn out to be this year’s losers, and vice-versa.

US households add $601bn of debt in 2019
American households borrowed another $601 billion (Dh2.2bn) in 2019, the largest yearly gain since 2007, just before the global financial crisis, according to February data from the New York Federal Reserve Bank.
Fuelled by rising mortgage debt as homebuyers continued to take advantage of low interest rates, the increase last year brought total household debt to a record high, surpassing the previous peak reached in 2008 just before the market crash, according to the report.
Following the 22nd straight quarter of growth, American household debt swelled to $14.15 trillion by the end of 2019, the New York Fed said in its quarterly report.
In the final three months of the year, new home loans jumped to their highest volume since the fourth quarter of 2005, while credit cards and auto loans also added to the increase.
The bad debt load is taking its toll on some households, and the New York Fed warned that more and more credit card borrowers — particularly young people — were falling behind on their payments.
"Younger borrowers, who are disproportionately likely to have credit cards and student loans as their primary form of debt, struggle more than others with on-time repayment," New York Fed researchers said.
