Man’s New Best Friend: The Robotic Dog

Boston Dynamics, a Boston-based engineering company, has recently demonstrated its prototype of BigDog, a robotic dog. While it may remind some of Ray Bradbury’s Fahrenheit 451, it has many others excited at its potential uses. A Youtube video of its demonstration has generated over 6 million hits, as well as garnering mentions in such prestigious publications as Army Times.

Sponsored by the US Defense Advanced Research Projects Agency, BigDog is intended to carry up to 340 pounds of equipment, while keeping up with foot soldiers in a combat environment.

Its gasoline-powered, hydraulic propulsion system allows it to move at speeds as high as 4 mph, over rough terrain, and up steep slopes, assisted by its triple-jointed legs. In addition, the robot also features an on-board computer, which tracks its “vital statistics,” such as oil temperature, hydraulic pressure, and battery life, and report them back to its controller.

While current models’ abilities are limited by remote control from bases, future models are expected to be capable of making basic decisions pertaining to its movements.

NSF Funds the first global engineering classroom

Engineering Students from the U.S. had a chance to work with other engineering students from Japan in a cross-cultural classroom setting. The students meet to learn about innovation in the field of glass science. The International Materials Institute (IMI) and the National Science Foundation (NSF) sponsored the pioneering program. Experts in the field from the U.S., Japan, Brazil and France taught the classes U.S. and Japanese students participated in. The students meet for two weeks in Kyoto, Japan.

Students looking to go abroad to do research in Asian countries also have the opportunity participate in another the NSF funded program. The East Asian and Pacific Summer Institute (EAPSI) program, funds students to do research in Asian and Pacific countries abroad. Although students don’t work in such a global classroom setting, they do stay with host families and have an opportunity to learn about another culture and gain access to the different resources and perspectives on their research project that the global environment provides.

How to Build an Electric Car Charging Infrastructure: Smart Grids, Fast Charging and Universal Access

“Green studies are among the fastest-growing degree programs at some universities” (posted Yesterday Green Degrees Environmental Courses Signal a Shift in Learning) making the topic of electric cars one that should interest both students and professors. Engineers will most likely be behind designing and implementing the grid system that will power these cars. gas2.0 provides an idea about how that might look.


India’s Engineering Education Dilemma

India is well known for its push to catch up to the United States and other countries economically. Currently it is the second fastest growing world economy (after China). However, in the process of economic growth, India has also drawn attention to its neglect to some main stay social issues, such as education. Although India has one of the largest labor forces in the world, most work in agriculture and are not highly educated. There is a huge divde in India between educated and uneducated citizens and it is now beginning to challenge India’s growth rate. Increasingly, India is forced to look else where, like China, to recruit future science and technology workers or come up with some creative ways to bring in more skilled workers from their own country.

U.S. Competitiveness in Science and Technology

According to an article this past January in the New York Times, entitled Global Advances Challenge U.S. Dominance in Science the United States is lagging behind the rest of the world in the development of new S&T talents. Thanks to globalization, Americans have become reliant on �foreign-born workers to fill technical jobs� with no end in site since efforts to fill student achievement gaps early on are not working. Many students and even adult Americans remain scientifically illiterate.

However, a new report released by the RAND Corporation reads the same statistics somewhat differently, putting a positive spin on globalization. The report, U.S. Competitiveness in Science and Technology (pdf here) looked at factors such as, R&D spending, triadic patents, publications, investment in science and math education and the science and engineering workforce to determine if the US was really falling behind. What it found is that in almost every area the United States is leading the way, contributing to about 40% of R&D spending and triadic patents worldwide. Additionally, the report noted that while �U.S. investments per student in elementary and secondary education are on par with those of other industrialized nations� its investments in post-secondary education are nearly double that of other countries.

As far as the S&E workforce is concerned, RAND was not too concerned, noting that growth in this area has been steady since 1980, largely due to foreign-born workers who �have helped enable� this trend.

So globalization seems good. Increase in foreign-born workers in the United States should already indicate how the U.S. has benefited from integration into a world-wide society. RAND also speculates the US can profit from it economically as well if Americans can embrace foreign gadgets.

The U.S. should not take S&E light- heartedly, but instead continue to try and counteract “exaggerated claims of the demise or success of U.S. science and technology”, RAND adds in a final statement. The article recommends three policy strategies that United States could adapt to continue going strong into the future, including, “establishing a centrally coordinated, independent body to monitor and evaluate U.S. performance in science and technology over the long term, facilitating high-skilled immigration to allow the United States to continue to benefit from employing foreign S&E workers and increase U.S. capacity to interact with science centers abroad and capitalize on the scientific and technological advances being made elsewhere.”

Google’s Green Energy Initiative – They are Hiring

Towards more renewable energy, posted to Google’s blog by Larry Page, Co-Founder and President of Products

Promising technologies already exist that could be developed to deliver renewable energy cheaper than coal. We think the time is ripe to build rapidly on the tremendous work on renewable energy. For example, I believe that solar thermal technology provides a very plausible path to generating cheaper electricity. By combining talented technologists, great partners and large investments, we have an opportunity to quickly push this technology forward. Our goal is to build 1 gigawatt of renewable energy capacity that is cheaper than coal. We are optimistic that this can be done within years, not decades. If we succeed, it would likely provide a path to replacing a substantial portion of the world’s electricity needs with renewable energy sources.

To lead this effort, we’re looking for a world-class team. We need creative and motivated entrepreneurs and technologists with expertise in a broad range of areas, including materials science, physics, chemistry, mechanical engineering, electrical engineering, land acquisition and management, power transmission and substations, construction, and regulatory issues. Join us. And if you’re interested, read about our previous work toward a clean energy future.

Once again the engineers leading Google show a willingness to make decisions that are unconventional. Google has shown itself to be very effective at managing engineers with great success. This will be quite a challenge but it is great to see Google taking it on. I will be surprised if there are not numerous complaints about Google losing focus. And they might but a big part of Google’s success is a willingness to challenge conventional wisdom. It will be interesting to see how this develops.

Engineering Fly Ash Bricks

Follow the “Green” Brick Road?

Each year, roughly 25 million tons of fly ash from coal-fired power plants are recycled, generally as additives in building materials such as concrete, but 45 million tons go to waste. Fly ash bricks both find a use for some of that waste and counter the environmental impact from the manufacture of standard bricks.

“Manufacturing clay brick requires kilns fired to high temperatures,” said Henry Liu, a longtime National Science Foundation (NSF) awardee and the president of Freight Pipeline Company (FPC), which developed the bricks. “That wastes energy, pollutes air and generates greenhouse gases that contribute to global warming. In contrast, fly ash bricks are manufactured at room temperature. They conserve energy, cost less to manufacture, and don’t contribute to air pollution or global warming.”

Supported by NSF’s Small Business Innovation Research (SBIR) program, Liu has been working since 2004 to develop the bricks. The first phase of support enabled him to make fly ash bricks more durable by engineering them to resist freezing and thawing due to weather. Liu is now working from a second-phase SBIR award to test the brick material’s safety and prepare it for market.
