1988 서울에서 2018 평창까지
2018 평창동계올림픽이 바야흐로 1,000일밖에 남지 않았다. 세계인들에게 도시의 이름마저 생소하게 느껴졌던 평창이 동계올림픽 개최지로 결정된 것은 지난 2011년 7월이다. 남아프리카공화국 더반에서 열린 123차 IOC총회에서 올림픽 개최지로 결정되기까지 평창은 2번의 고배를 마셔야 했다. 하지만 이렇게 평창에서 올림픽이 열린 것은 결코 우연이 아니다. 한국은 이미 올림픽과 깊은 인연이 있는 나라이다.

Colder weather is on the way. If you’re in Winnipeg, Canada, that means ice testing is too. There, @geaviation test engines are pummeled with sub-zero winds and ice. The harsh conditions on the ground make sure engines are ready to face the elements in the air. #AVgeek #jetengine #engineering
Spooky season is here, but don't let your annual mammogram scare you. Nearly 30% of women in the U.S. admit to skipping breast screenings out of fear. That's why @gehealthcare engineers decided to better the experience with a mammography system designed by women, for women. Melding comforting design with cutting edge technology, the Senographe Pristina aims to humanize the process for patients, technicians, and radiologists. #BCAM #Mammography #breastcancerawareness
Wind, meet water. In Germany’s Swabian-Franconian Forest, you’ll find the world’s tallest (584 ft) and first-ever wind turbines integrated with pumped storage hydroelectric power. So how does it work? At the base of each wind turbine sits a reservoir. Water flowing downhill from the reservoirs will power the hydro plant when electricity is needed. When there’s an energy surplus, the hydro power will push the water back up the hill to the reservoirs, where it will act as a giant battery for the wind turbines. So no matter if the wind is blowing or not, electricity will always be flowing
Slice into an additively-made part from @geadditive and you’ll see geometries once thought impossible with traditional manufacturing methods. Why the hype? Engineers can now find greater strength and efficiency through design. #engineering #additive #3Dprinting #manufacturing
This Ultra Performance Heat Exchanger is a perfect example of how small parts can make a HUGE difference. Still in development, the additively manufactured compact heat exchanger is printed with a high-temperature capable, crack-resistant nickel superalloy that will be able to withstand temps that exceed 1,650°F at pressures >3,600 psi. Good thing, too, because it’s headed straight for the inside of a gas turbine, where it’s projected to deliver a 4% improvement in thermal efficiency for supercritical C02 power cycles while improving power output and reducing emissions. Cleaner, more efficient power generation here we come.
