우리는 아주 훌륭한 행성의 일부이며 특별한 재능에 둘러싸여 있다. 자연에서 축적된 노하우를 사용하여 사람들의 니즈와 욕망을 충족시키는 무한한 솔루션을 제공할 수 있다는 전망은 아주 매력적이다. 이제 최근에 현실 속에서 실제로 사용되고 있는 몇 가지 생체모방 사례들을 살펴보도록 하자.

2015년, 미래를 만드는 GE의 11가지 기술

2015년 2월 11일

GE글로벌리서치는 GE의 혁신을 이끄는 원동력이다. 수천의 특허를 보유하고 있으며 여러 명의 노벨상 수상자를 배출해냈다. 오늘날 이 연구소는 브라질, 중국, 독일, 인도에 소재하며 3,000여 명의 과학자들에게 연구의 터전이 되고 있다. 이곳에서 진행되고 있는, 앞으로의 세상을 바꾸게 될 11가지 연구를 살펴보도록 하자.

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.
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
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
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
