Here are some of the Olympians who have shown the spirit of the Olympics in their unique ways at the 2022 Beijing Olympic Games.

Brittany Bowe

The 33-year-old Brittany Bowe voluntarily gave up her spot on the US 500-meter speedskating team to her teammate and friend Erin Jackson. It cost her one of the two spots at the 2022 Beijing Olympic Games. Jackson, the world’s top-ranked woman for the event, slipped during the US Olympic qualifying contest.

“You are always ranked number one in the world and no one is more deserving than you to get an opportunity to compete in Beijing,” Bowe told Jackson.

Mikaela Shiffrin

The 26-year-old Alpine skier, who has won more World Cup races than anyone in history, woman or man, didn’t finish three of her five races in Beijing after either falling or skiing out of the course within a matter of seconds.

“I don’t know if anybody’s failed that hard with so many opportunities — maybe in the history of the Olympics. But I will face those failures with sportsmanship,” she joked.

Eileen Gu

The 18-year-old “Snow Princess” has struggled in qualifying in both of her Olympic events. She fell once during the big air jumps and had to increase the technical difficulty in the third round to ensure her spot in the final, where she went on to win the gold medal,

“I don’t know why I kept failing,” Gu said. “But I’m happy I was able to turn pressure into fuel and push through, ”

Lindsey Jacobellis

After a 16-year medal drought (旱季), the 36-year-old eventually overpowered a much younger field of competitors during the women’s snowboard cross and won her first career (职业) gold in Beijing. She went on to compete at the first-ever mixed team snowboard cross event with 40-year-old teammate Nick Baumgartner — again winning gold.

“Don’t count the old girl out,” Jacobellis said jokingly.

Watching his father die without oxygen support while suffering from a heart attack in 2020, Taher Mahmud Tarif, a Bangladeahi boy, made up his mind to build a device to prevent any more such tragic deaths. Afterwards, many COVID-19 patients experienced low oxygen levels in their blood, with demand for oxygen concentrators (浓缩器) among other medical equipment shooting up during the recent sharp rise in cases. Tarif said the situation gave him more driving force to build the device.

With the financial and overall support of Ishwardi UNO office and his educational institution, Tarif's determination and tireless efforts were rewarded with success as the ninth grader of Ishwardi Sara Marwari High School managed to make the concentrator after trying five times for about seven months, mainly using domestic components. He said that a locally made oxygen eoncentrator like his costs approximately $ 760 whereas an imported one does over $2,600.

In June, Tarif gave a detailed account of his invention and manufacture at the UNO office in Ishwardi at 11:00 am on Tuesday. He said it was created from his own thinking and with the addition of local technology generators and electric components. An oxygen concentrator takes in air and removes nitrogen (氮气) from it, leaving oxygen-enriched gas for use by people needing medical oxygen. “About 90 percent oxygen concentration can be generated from my oxygen concentrator machine. This machine can provide high-flow oxygen supply too. It can be very handy in local areas with no scope of getting oxygen support,”Tarif added.

“This is obviously a good invention for oxygen generation. It is capable of producing high-flow oxygen so it can be used for patients or refilling oxygen bottles,” said an assistant professor of Pabna Medical College Hospital. “Despite more lab and other examinations before using the machine as medical equipment,” the UNO said, “Tarif's invention will probably be a great achievement during this alarming COVID-19 situation.”

The head of the Virgin Hyperloop (超级高铁) transport system says the company aims to begin carrying passengers by 2027.

The Virgin Hyperloop system is based on a technology called magnetic levitation (磁悬浮). It uses magnetic fields to lift a vehicle off the ground a little and to push it forward.

Some high-speed trains also use this technology. But unlike trains, a Hyperloop is designed to operate within tubes containing very little air. Electric force moves vehicles, called pods, through the tubes at high speeds. The system offers nearly silent travel and reportedly releases no carbon emissions.

The system’s pods are designed to move at much higher speeds, up to 1,200 kilometers per hour. It says such a vehicle could complete a trip between New York and Washington, D.C. in 30 minutes. That would be two times as fast as a jet flight and four times faster than a high-speed train.

The pods will seat 28 passengers and could be specially designed to travel long or short distances, or to carry goods, the company said.

While the system is still in early development, it is predicted that commercial operations could start as early as 2027. Virgin Hyperloop is looking to first develop passenger systems in India, where the transport system is overcrowded, and in Saudi Arabia, which lacks infrastructure (基础设施).

It could be the first form of transportation in 100 years to revolutionize travel, as cars, trains and airplanes did before. “It starts off with two people riding a Hyperloop. It ends with hundreds of millions of people riding on a Hyperloop and that’s what the 2020s—the roaring 2020s—will be,” he added.

Virgin Hyperloop has partners that include Virgin Group founder Richard Branson and the port operations company DP World, which is owned by the Dubai government.
