Young engineer’s smart prepaid meter helps remote villages gain access to electricity

12/09/13 dnaindia.com — When Yashraj Khaitan traveled to remote villages in India in 2009 as a member of Engineers without Borders, he came back with the idea for Gram Power, a company that provides remote areas with on-demand, reliable electricity through affordable prepaid purchases modeled on cellphone recharge plans.

A carbon map to development

10/15/13 Daily Californian — In a Daily Cal op-ed, Dean Shankar Sastry calls for an international roadmap for economic growth, job creation and poverty alleviation that also contributes to controlling greenhouse gas emissions.

Plate piles keep levees intact

05/13/13 — In the basement of Davis Hall, Hamed Hamedifar (Ph.D'12 CEE) is rattling scale models of levees on a shake table, subjecting them to vibrations replicating the magnitude 6.9 El Centro earthquake of 1940. Hamedifar is designing a plate pile system, rectangular plates affixed to three-yard beams, to bolster the strength of levees in places like the California Delta.

The worldwide reach of Berkeley Engineering

03/05/13 — Global problems demand global cooperation. To tackle a wide range of challenges, from clean energy and intelligent infrastructure to cost-effective healthcare delivery, we are launching ambitious research and teaching partnerships with a number of international colleagues.

Riding the wave

03/05/13 — A member of the Berkeley faculty for less than two years, mechanical engineer Reza Alam is already making waves. His efforts to “cloak” objects at sea could one day help shield oil drilling platforms, wind turbine towers or data-collecting buoys from rough seas. His inspiration came from beyond his field: “I was reading papers about electromagnetic cloaking and started thinking, can we do something similar in fluids?”

Sink or swim

02/07/13 — To test new modeling software from DARPA, teams of students from mechanical engineering professor Homayoon Kazerooni's ME 102B mechatronics design class spent months building a fleet of amphibious vehicles, along with other inventions and novel devices. Then in early December, they put their creations to the test on the soggy volleyball court behind Soda Hall - with splashy results.

A new loo

02/07/13 — Answering a challenge from the Bill and Melinda Gates Foundation to improve sanitation in developing countries, environmental engineering professor Kara Nelson and postdoctoral researcher Temitope Ogunyoku have developed a toilet that safely disinfects waste. Their hand-cranked pHree Loo yields “safe sludge” that does not endanger human health.

Quake model aids in fault studies

11/05/12 — A new civil engineering study reveals that the more time an earthquake fault has to heal, the faster the shake it will produce when it finally ruptures. Because the rapidity and strength of the shaking are what causes damage to major structures, the new findings could help engineers better assess the vulnerabilities of buildings, bridges and roads.

A new loo

11/01/12 — In response to a challenge posed by the Bill and Melinda Gates Foundation to develop toilets that are clean, affordable and sustainable for the 2.5 billion people who lack access to modern latrines, engineering professor Kara Nelson and postdoctoral student Temitope Ogunyoku designed a new loo.

Image makers

11/01/12 — To reduce or even eliminate the use of anesthesia for pediatric patients during MRIs, EECS professors have developed a way to drastically reduce the time needed to conduct MRI exams.

Within reach

11/01/12 — Director of the Brain-Machine Interface Systems Lab Jose Carmena discusses the future of meshing mind and machine.

Prepaid power

11/01/12 — Two Berkeley alumni started a microgrid project to bring electricity to places too remote to have cost-effective connections to traditional utility-scale power grids.

Arsenic water filter recognized with international prize

10/09/12 Berkeley Lab — A team led by Ashok Gadgil, Berkeley Engineering professor and head of LBNL's environmental energy technologies division, has received the Prince Sultan Bin Abdulaziz International Prize for Water. The prize recognizes his team's advances in developing an effective and economical way to treat arsenic contamination in groundwater.

Cal Energy Corps working worldwide on smart solutions

09/24/12 — Launched in 2011, the Cal Energy Corps provides undergraduates with practical research and experiential-learning opportunities through internships with partner organizations across the academic, corporate and nonprofit sectors. Modeled on the U.S. Peace Corps, the program aims to engage Berkeley students tackling alternative energy, climate change and sustainability issues around the world. This summer, 13 of the 32 Cal Energy Corps interns were Berkeley Engineers

Decoding pictographs: There’s an app for that

06/26/12 — Never mind the labyrinthine streets, chaotic traffic and unfamiliar food: If you talk to many foreign travelers to China, they'll tell you the most challenging part of a journey there is the language barrier. And it's not just the spoken language; the written characters of Chinese are equally confounding. With thousands of symbols making up the Chinese script, deciphering a street sign, menu or train ticket can be an onerous task for tourists.

The education of a maker

05/17/12 — Parents like Tony DeRose (Ph.D'85 CS), senior scientist and research group lead at Pixar Animation Studios, are all too familiar with the difficulty of finding something engaging for their children to do with their hands. “When my son grew out of Legos at about eight years old, we realized there wasn't much for him to graduate into,” DeRose says. That's when DeRose and his son began working on projects in their garage. Most of the projects went unfinished until they discovered the Maker Faire. From there, DeRose and his son were hooked. DeRose wanted to bring the Maker Faire to more students and co-founded the Young Makers program in 2010.

Preventive medicine for pipelines

05/17/12 — Nationwide, our network of more than 2.5 million miles of pipeline is aging. More than a third of the pipeline infrastructure is over 50 years old, and a reliable method to monitor corrosion hasn't really existed. Until now. Jerome Singer, professor emeritus of EECS and engineering science, and two Berkeley Engineering alums have developed a way to keep tabs on pipeline health by using an MRI machine similar to the ones used in hospitals. Their technology is called the Magnetic Response Imaging System (MRIS), and it will be able to look at the state of underground pipelines.

Berkeley Engineering’s Ashok Gadgil honored for bridging innovation and humanitarianism to help millions globally

05/02/12 Business Wire — Dr. Ashok Gadgil is the recipient of the 2012 $100,000 Lemelson-MIT Award for Global Innovation in recognition of his steady pursuit to blend research, invention, and humanitarianism for broad social impact. Gadgil is a chair professor of Safe Water and Sanitation at UC Berkeley, and director of the Environmental Energy Technologies Division at Lawrence Berkeley National Laboratory.
