Building green performance motorcycles

04/17/12 — Electric motorcycles are quiet, and from a power perspective more efficient. Both traits are not lost on the rider. “If you get on these electric motorcycles the first thing you notice is a magic carpet ride feel,” says Abe Askenazi, B.S'92, M.S'94 ME. “It's almost like flying. It feels like you are on a glider and this thing is propelling you forward. You don't hear all of the drama of power production, you are just doing it.” Askenazi has traveled a long road to become the chief technology officer at Zero Motorcycles, one of the nation's leading electric motorcycle manufacturers.

Speaking from experience

06/07/11 — As one of the student speakers at Berkeley Engineering's commencement last month, Christopher Ategeka (B.S'11 ME) recounted his formidable journey to Berkeley from the rural Ugandan village of his childhood. His odyssey entailed unimaginable heartbreak and hardship. For Ategeka, who will return to Berkeley in the spring of 2012 to begin a doctoral program in mechanical engineering, luck as well as a positive outlook helped get him where he needed to go. There was one tool, however, that also played a pivotal role in his success: the bicycle.

Exoskeleton lets UC Berkeley grad take a huge step

05/15/11 San Francisco Chronicle — When Austin Whitney, a paralyzed 22-year-old UC Berkeley student, rose from his wheelchair and stepped across the commencement stage on Saturday to shake Chancellor Robert Birgeneau's hand, the crowd of 15,000 at Edwards Stadium went wild with cheers, as if witnessing a miracle. A team of UC Berkeley mechanical engineers - four doctoral students led by Professor Homayoon Kazerooni - have been developing a computerized body brace called an exoskeleton they believe will be good enough to transform thousands of wheelchair users into walking people in a couple of years, and for an affordable price.

Sun-driven and Australia-bound

The laser whisperer

03/02/11 — A research team led by Xiang Zhang, professor of mechanical engineering and faculty scientist at Lawrence Berkeley Laboratory, has taken inspiration from the phenomena of whispering galleries - such as the U.S. Capitol's Statuary Hall or Grand Central Terminal in New York - and their remarkable acoustical features to achieve a major scientific breakthrough in the use of plasmon lasers. By creating a technique to bounce surface plasmons inside of a nanosquare device, much in the way sound waves reflect back and forth in a whispering gallery, the team was able to operate plasmon lasers at room temperature, overcoming what had been a major barrier to practical utilization of the technology.

How to measure an oil spill

02/02/11 — When oil was flowing from BP's broken well at the bottom of the Gulf of Mexico last spring, the company estimated the flow rate at about 1,000 barrels a day. But news outlets wanted an independent estimate. Could Ömer Savaş, an expert in fluid mechanics and turbulent flows, help? Soon Savaş became involved in a national effort to establish the “official” flow rate, a number that would dictate not only the level of resources assigned to the cleanup but also its legal ramifications once the emergency had passed.

Berkeley scientists create more efficient photocatalyst for use in clean technologies

01/29/11 AZoM — A little disorder goes a long way, especially when it comes to harnessing the sun's energy. Scientists from Berkeley Lab jumbled the atomic structure of the surface layer of titanium dioxide nanocrystals, creating a catalyst that is both long lasting and more efficient than all other materials in using the sun's energy to extract hydrogen from water. "We are trying to find better ways to generate hydrogen from water using sunshine," says Samuel Mao, a mechanical engineering professor and scientist in Berkeley Lab's Environmental Energy Technologies Division who led the research.

Think globally, surf locally

10/05/10 — Modern surfboards are made with polyurethane foam, fiberglass and epoxy resin, decidedly unromantic and toxic petrochemicals that can harm workers and the environment during manufacture, then languish in landfills at the end of their life. Many manufacturers are making surfboards greener by switching to natural materials. They're doing the right thing, right? Not necessarily, says 26-year-old Tobias Schultz (M.S.'10 ME), a lightly tanned, blond-ponytailed Santa Cruz native who just graduated with his mechanical engineering master's and a certificate in Engineering and Business for Sustainability. He is also the author of an extensive study on the carbon footprint of the surfing lifestyle.
