다시 한 번 블링블링, 제트엔진에서 백금을
은빛 원소 백금의 유용성은 엄청나며 많은 분야에 사용 된다. 따라서 과학자들이 단 1그램의 백금이라도 더 회수하려 애쓰는 건 당연하다. 항공우주 산업 전반을 통틀어 한 해 약 백만 개 이상의 고압블레이드가 수거되어 폐기된다. 하나의 블레이드에는 1그램의 백금이 포함되어 있고. GE의 첨단기술을 활용하여 백금을 추출하면 엄청난 비용 절감이 가능하다.

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
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
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.
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
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
