Round-the-world solar plane leaves Myanmar for China

Published

Mandalay: The Solar Impulse (Si2), the solar-powered aircraft on a mission to fly around the globe without a drop of fuel, left Mandalay in Myanmar for China on Sunday on the fifth leg of its journey.

The aircraft, piloted by the Swiss project chairman Bertrand Piccard, left Mandalay at 3.36 a.m. on Sunday, and is heading for Chongqing in China, according to a report.

Leg five of the aircraft will be a long one — about 1,375 km — and is expected to take roughly 19 hours.

It will see the Si2 landing around midnight at the Chongqing Jiangbei International Airport.

The plan of the project team is to make a brief stop in Chongqing, and then try to reach Nanjing on the east coast of China.

This would set up the Si2 for the first of its big ocean crossings — a five-day, five-night flight to Hawaii.

Capable of flying over oceans for several days and nights in a row, the single-seater Si2, which started its journey from Abu Dhabi in the United Arab Emirates (UAE) on March 9, will travel 35,000 km around the world in 25 days.

Mission control will not make a decision on the Nanjing leg until late on Monday.

The decision may rest on the state of the energy reserves held in the plane’s batteries.

China’s air traffic authorities would like the aircraft to start its sixth leg before dawn. However, if the reserves are marginal then the Si2 will be held in Chongqing until the batteries can be charged.

The problem with this scenario was that poor weather had been forecast in the Chongqing region in the coming days, and if the aircraft did not leave straightaway, it could be delayed for perhaps a week, reports said.

The project team expects the circumnavigation of the globe to be completed in a total of 12 legs, with a return to the UAE in a few months’ time.

In the past month, the Si2 set two world records for manned solar-powered flight.

The first was for the longest distance covered on a single journey — that of 1,468 km between Muscat in Oman and Ahmedabad in India.

The second was for a groundspeed of 117 knots (216 kmph), which was achieved during the flight from Varanasi in India to Mandalay.

The wingspan of the aircraft is 72 metres, which exceeds that of a 747 jumbo jet airliner. It, however, weighs only 2.3 tonnes, which is equivalent to that of a small car.

The light weight of the Si2 will be critical to its success over the coming months.

So too will the performance of the 17,000 solar cells that line the top of the aircraft’s wings, and the energy-dense lithium-ion batteries that it will use to sustain night-time flying.

No solar-powered plane has ever flown around the world.

The Si2 venture is reminiscent of other great circumnavigation feats in the history of aviation, albeit fuelled ones.

In 1986, the Voyager aircraft became the first to fly around the world without stopping or refuelling. The propeller-driven vehicle took nine days to complete its journey.

Then, in 2005, the time set by Voyager was beaten by the Virgin Atlantic GlobalFlyer, a jet-powered plane, which completed its non-stop circumnavigation in just under three days.

The Si2 project aims to demonstrate the promise of clean energy.

Lockdowns in China Force Urban Communities to Defy Censorship and Vent Frustration Online

Shanghai’s rich middle class is leading a wave of online dissent over the strict and prolonged lockdowns imposed in various parts of the country. Chinese internet censorship is struggling as patience is wearing thin in many urban centers, coming up with creative forms of online protests.

Social Media Posts Revealing Lockdown Tension in Shanghai

Drawn-out lockdowns are nothing new in China as authorities insist with the nation’s zero-Covid policy since the start of the pandemic. Currently over This time around, however, metropolitan areas like Shanghai are increasingly difficult to keep quiet, given that its more than 25 million residents have seen weeks of total isolation along with food shortages and many other service interruptions.

Dozens of towns and reportedly over 300 million Chinese citizens have been affected by lockdowns of different severity. As expected, urban netizens have been most outspoken over their difficulties by finding creative ways to get around state censorship and bans placed on topics, news comments and spontaneous campaigns.

Shanghai residents have been using mobile proxies and hijacking seemingly unrelated hashtags to talk about healthcare issues, delivery failures and the overall severity of their situation. The “positive energy” that the Chinese government wants to transmit during the recent prolonged series of lockdowns does not come naturally to those counting food supplies and online censors are working hard to filter words, trending topics and undesired social media sharing.

WeChat groups and message threads are under constant monitoring. Posts questioning the zero-Covid approach have been quickly deleted, including by leading Chinese health experts like Dr. Zhong Nanshan. Video footage is soon censored and protests and investigations are quickly made to disappear.

Where this has not worked, officials have exposed banners with warnings and outright threats like “watch your own mouth or face punishment”, while drones have been patrolling the city skies. Yet, if anything, this has led to further tensions and unspoken confrontation with Shanghai’s educated and affluent middle class.

Creative Online Solutions Harnessing Civic Energy

Announcements by Chinese social media that they would be publishing the IP addresses of users who “spread rumors” have not helped either. Tech industry research has shown that much of Asia’s tech-savvy population has a habit of using mobile proxies and other privacy tools, quickly finding workarounds to browse the internet freely and talk to the world about the hottest topics.

The sheer volume of forbidden posts is already a challenge for the very censorship system, experts explain. Unable to track all trending hashtags, state workers overlook topics that speak about the US, Ukraine or other popular news. Linking human rights elsewhere to their situation, Chinese online dissidents establish their informal channels and “hijack” the conversation to share personal or publicly relevant information about the Covid suppression in their town.

Sarcastic and satirical posts still dominate. Others hope to evade the censors by replacing words from famous poems or the national anthem. One thing is certain – social media, when harnessed with the right creativity, has proven its ability to mount pressure on the government in even some of the most strictly controlled tech environments like China.
