"Turbulence is everywhere," says Professor Beverley McKeon—from continent-spanning weather systems down to the swirls of air your car leaves behind itself as you drive. "I think about things like ships, planes, and pipelines," she explains, noting that about half of the energy consumed by each of those three transportation systems goes to counteract turbulence-induced drag. In her Watson Lecture she notes that finding a way to reduce that turbulence by 30 percent would save the global economy well over $100,000,000 dollars in fuel costs annually. [Learn More]
Paul MacCready Papers to be Digitized
The MacCready family have made a generous gift for the processing and digitizing of the papers of Caltech alumnus, inventor and entrepreneur Paul B. MacCready (1925-2007). Paul B. MacCready pioneered alternative energy solutions through his company, AeroVironment. In the mid-1970s he began work on the celebrated human-powered Gossamer aircraft series, beginning with the Gossamer Condor. He continued to work on the problems of solar-powered flight and unmanned aircraft, but his interest in environmentally friendly technology also led him to innovative electric and hybrid automotive vehicles, micro-air vehicles and the high altitude, long endurance Helios solar aircraft for telecommunications, imaging and scientific research.
The MacCready digitization project will be the first on the part of the Caltech Archives to make an entire paper, artifact, image and analog media collection available on the internet to the widest possible public. [Archives News]
Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Professor of Bioinspired Engineering, and colleagues are studying the properties of the zebrafish embryonic heart to address problems as diverse as ringing in the ears and overheated electronics. They have also developed the first pump built entirely from biological building blocks. “We can actually be more clever than nature,” Gharib says. “We can get inspired by nature and use engineering to come up with better functions. Just look at 747s—they fly from LAX to La Guardia much more efficiently than any bird could.”
