Solar Impulse grounded for repairs



Solar Impulse 2 will be grounded in Hawaii until early next month to undergo maintenance repairs following its recent record-breaking, five-day non-stop oceanic flight.

The solar-powered aeroplane of Swiss pilots Bertrand Piccard and Andre Borschberg sustained damage to its batteries when they overheated while completing the longest and most difficult leg – from Japan to Hawaii – of the round-the-world flight.

During the first ascent of the flight from Nagoya to Hawaii, the battery temperature increased because of too much insulation.

While the mission control team monitored the issue there was no way of reducing the temperature for the remainder of the flight because each daily cycle required an ascent to 28,000 feet and descent for energy-management issues.

The damage to certain parts of the batteries is irreversible and requires repairs and replacements that will take several weeks to complete.

The Solar Impulse engineering team is looking at various options for improved management of the cooling and heating process for long flights.

The team does not see the possibility for any flights before two weeks at the earliest, it said.

Solar Impulse is attempting the first round-the-world solar-powered flight to inspire innovation and pioneering spirit and encourage the adoption of clean technologies, renewable energy and energy efficiency.

Having started in Abu Dhabi in early March, the plane has completed eight legs covering nearly 18,000 kilometres.

The Masdar-sponsored plane is expected to complete its mission back in Abu Dhabi after completing its final five flights later this year.

Subj: Accelerating in the Middle East

Five years ago, Uber launched in the Middle East. It was the start of an incredible journey, with millions of riders and drivers finding new ways to move and work in a dynamic region that’s become so important to Uber. Now Pakistan is one of our fastest-growing markets in the world, women are driving with Uber across Saudi Arabia, and we chose Cairo to launch our first Uber Bus product late last year.

Today we are taking the next step in this journey—well, it’s more like a leap, and a big one: in a few minutes, we’ll announce that we’ve agreed to acquire Careem. Importantly, we intend to operate Careem independently, under the leadership of co-founder and current CEO Mudassir Sheikha. I’ve gotten to know both co-founders, Mudassir and Magnus Olsson, and what they have built is truly extraordinary. They are first-class entrepreneurs who share our platform vision and, like us, have launched a wide range of products—from digital payments to food delivery—to serve consumers.

I expect many of you will ask how we arrived at this structure, meaning allowing Careem to maintain an independent brand and operate separately. After careful consideration, we decided that this framework has the advantage of letting us build new products and try new ideas across not one, but two, strong brands, with strong operators within each. Over time, by integrating parts of our networks, we can operate more efficiently, achieve even lower wait times, expand new products like high-capacity vehicles and payments, and quicken the already remarkable pace of innovation in the region.

This acquisition is subject to regulatory approval in various countries, which we don’t expect before Q1 2020. Until then, nothing changes. And since both companies will continue to largely operate separately after the acquisition, very little will change in either teams’ day-to-day operations post-close. Today’s news is a testament to the incredible business our team has worked so hard to build.

It’s a great day for the Middle East, for the region’s thriving tech sector, for Careem, and for Uber.

Uber on,

Dara

Safety 'top priority' for rival hyperloop company

The chief operating officer of Hyperloop Transportation Technologies, Andres de Leon, said his company's hyperloop technology is “ready” and safe.

He said the company prioritised safety throughout its development and, last year, Munich Re, one of the world's largest reinsurance companies, announced it was ready to insure their technology.

“Our levitation, propulsion, and vacuum technology have all been developed [...] over several decades and have been deployed and tested at full scale,” he said in a statement to The National.

“Only once the system has been certified and approved will it move people,” he said.

HyperloopTT has begun designing and engineering processes for its Abu Dhabi projects and hopes to break ground soon. 

With no delivery date yet announced, Mr de Leon said timelines had to be considered carefully, as government approval, permits, and regulations could create necessary delays.
