Companies Sharing Engineering Resources Across the Globe

Posted on December 2, 2011  Comments (1)

Swapping batteries for diesel engines

Car companies, like aircraft manufacturers, are sharing engineering skills across borders to speed up and cut the costs of technological development. It happened with Boeing’s 787 Dreamliner. The American aircraft maker outsourced some of the engineering to Japanese suppliers, admitting that it does not have all the necessary expertise. Likewise, Toyota has agreed to work on hybrid trucks with Ford, and electric vehicles with Tesla, the Silicon Valley sports-car maker. BMW is working on improving the current generation of lithium-ion batteries with France’s Peugeot Citroën. Nissan, as well as joining forces with Renault, has joint projects with Daimler.

There are many reasons to pursue such efforts (as well as drawbacks). My belief is companies would rather not take on the complications of such partnerships but the advantages overcome those desires. The high cost of research into these efforts is a big part of what pushes such collaboration. Also once a company has success they often can build up quite an advantage. The costs of trying to engineer a different solution (that doesn’t violate someone’s patents) often makes buying that technology or partnering attractive.

I really like this webcast, from 2008, on Toyota’s engineering development program.

Nice Program on Mexican Free-tailed Bats

Posted on May 23, 2011  Comments (0)

Mexican free-tailed bats in the Central Valley, California: the voracious insect-eating species protects the local crops from pests. Bats really are wonderful animals and very beneficial to people. They eat many insects and some also help pollinate some plants. The Mexican free-tailed bats seem to even benefit from human activity (taking advantage of bridge underpasses as homes, for example), but many other bat species are in trouble.

Google Invests $168 million in Largest Solar Tower Power Project

Posted on April 12, 2011  Comments (3)

Google is investing in a new solar tower power project located in California that will generate 392 gross MW of clean, solar energy. That’s the equivalent of taking more than 90,000 cars off the road. Google has now invested $250 million in clean energy.

Investing in the world’s largest solar power tower plant

works by using a field of mirrors, called heliostats, to concentrate the sun’s rays onto a solar receiver on top of a tower. The solar receiver generates steam, which then spins a traditional turbine and generator to make electricity. Power towers are very efficient because all those mirrors focus a tremendous amount of solar energy onto a small area to produce steam at high pressure and temperature (up to 1000 degrees F).
…
Several large solar projects are in the works in the sunny Southwest (and around the globe), but Ivanpah will be the first solar power tower system of this scale. The Ivanpah Power Tower will be approximately 450 feet tall and will use 173,000 heliostats, each with two mirrors.

The Department of energy is also providing financing for this project. The project is 10 times larger than the largest solar photovoltaic project in California.

Bee Colonies Continue to Collapse

Posted on May 3, 2010  Comments (1)

The activity to find the causes of Colony Collapse Disorder provides a view into the scientific inquiry process of complex living systems. Finding answers is not easy.

Fears for crops as shock figures from America show scale of bee catastrophe

Disturbing evidence that honeybees are in terminal decline has emerged from the United States where, for the fourth year in a row, more than a third of colonies have failed to survive the winter.

The decline of the country’s estimated 2.4 million beehives began in 2006, when a phenomenon dubbed colony collapse disorder (CCD) led to the disappearance of hundreds of thousands of colonies. Since then more than three million colonies in the US and billions of honeybees worldwide have died and scientists are no nearer to knowing what is causing the catastrophic fall in numbers.
…
It is estimated that a third of everything we eat depends upon honeybee pollination.
…
Potential causes range from parasites, such as the bloodsucking varroa mite, to viral and bacterial infections, pesticides and poor nutrition stemming from intensive farming methods.
…
“We believe that some subtle interactions between nutrition, pesticide exposure and other stressors are converging to kill colonies,” said Jeffery Pettis, of the ARS’s bee research laboratory.
…
“It’s getting worse,” he said. “The AIA survey doesn’t give you the full picture because it is only measuring losses through the winter. In the summer the bees are exposed to lots of pesticides. Farmers mix them together and no one has any idea what the effects might be.” Pettis agreed that losses in some commercial operations are running at 50% or greater.

High Levels of Miticides and Agrochemicals in North American Apiaries: Implications for Honey Bee Health (open access paper on the topic, March 2010)

The 98 pesticides and metabolites detected in mixtures up to 214 ppm in bee pollen alone represents a remarkably high level for toxicants in the brood and adult food of this primary pollinator. This represents over half of the maximum individual pesticide incidences ever reported for apiaries. While exposure to many of these neurotoxicants elicits acute and sublethal reductions in honey bee fitness, the effects of these materials in combinations and their direct association with CCD or declining bee health remains to be determined.

Engineering Majors Hold 8 of Top 10 Highest Paid Majors

Posted on February 8, 2010  Comments (7)

In August, employers responding to a NACE survey reported plans to trim their college hiring, hiring 7% for 2010 graduates from 2009. In addition, just 29% of those employers said they would increase their starting salary offers for the Class of 2010.

Most, but not all majors, experienced salary decreases. In fact, as a group, graduates with computer-related degrees (computer programming, computer science, computer systems analysis, and information sciences/systems) posted a 6.1% increase – the highest increase reported, which pushed their average up from $56,128 to $59,570. Among those earning a computer science degree, the average rose 4.8% to $61,205.

As a whole, engineering graduates also fared well. Their average salary offer as a group is up by 1.2% to $59,245. Although that increase is modest, engineering majors account for eight of 10 top-paid bachelor’s degrees in the Winter 2010 Salary Survey.

Major Average Salary Offer
Petroleum Engineering

$86,220
Chemical Engineering

$65,142
Mining & Minteral Engineering (incl. geological)

Related: President Obama Speaks on Getting Students Excited About Science and Engineering – Presidential Awards for Excellence in Science, Mathematics and Engineering Mentoring – Fund Teacher’s Science Projects – $12.5 Million from NSF For Educating High School Engineering Teachers

Remarks by President Obama on the “Educate to Innovate” Campaign and Science Teaching and Mentoring Awards, January 6, 2010

To all the teachers who are here, as President, I am just thrilled to welcome you, teachers and mentors, to the White House, because I believe so strongly in the work that you do. And as I mentioned to some of you, because I’ve got two girls upstairs with math tests coming up, I figure that a little extra help from the best of the best couldn’t hurt. So you’re going to have assignments after this. (Laughter.) These awards were not free. (Laughter.)

We are here today to honor teachers and mentors like Barb who are upholding their responsibility not just to the young people who they teach but to our country by inspiring and educating a new generation in math and science. But we’re also here because this responsibility can’t be theirs alone. All of us have a role to play in building an education system that is worthy of our children and ready to help us seize the opportunities and meet the challenges of the 21st century.

Whether it’s improving our health or harnessing clean energy, protecting our security or succeeding in the global economy, our future depends on reaffirming America’s role as the world’s engine of scientific discovery and technological innovation. And that leadership tomorrow depends on how we educate our students today, especially in math, science, technology, and engineering.

But despite the importance of education in these subjects, we have to admit we are right now being outpaced by our competitors. One assessment shows American 15-year-olds now ranked 21st in science and 25th in math when compared to their peers around the world. Think about that — 21st and 25th. That’s not acceptable. And year after year the gap between the number of teachers we have and the number of teachers we need in these areas is widening. The shortfall is projected to climb past a quarter of a million teachers in the next five years — and that gap is most pronounced in predominately poor and minority schools.

And meanwhile, other nations are stepping up — a fact that was plain to see when I visited Asia at the end of last year. The President of South Korea and I were having lunch, and I asked him, what’s the biggest education challenge that you have? He told me his biggest challenge in education wasn’t budget holes, it wasn’t crumbling schools — it was that the parents were too demanding. (Laughter.) He’s had to import thousands of foreign teachers because parents insisted on English language training in elementary school. The mayor of Shanghai, China — a city of over 20 million people — told me that even in such a large city, they had no problem recruiting teachers in whatever subject, but particularly math and science, because teaching is revered and the pay scales are comparable to professions like doctors.

Zubbles – Get Your Colored Bubbles

Posted on December 3, 2009  Comments (0)

photo of blue bubblephoto of blue colored bubble.

I first posted on this in 2005: Colored Bubbles. Now you can order your own via Zubbles. Colored Bubbles Have Landed (and Popped and Vanished)

Having solved the colored bubble dilemma, we spent most of 2006 trying to refine our dyes and the manufacturing process. We had invented several completely new dyes and a few derivatives of existing dyes. But the manufacturing process was long, tedious and expensive. It took three days just to make a few grams of each dye. It quickly became apparent that we needed to radically streamline the production process in order to have a viable product.
…
The complexities of the chemistry resembled a pharmaceutical more than a toy. So I enlisted the help of Gary Willingham, and the Belgium development team, at Fisher Scientific. Fisher is a pharmaceutical chemical manufacturer with the equipment and expertise needed to manufacture tons of our dyes.
…
Due to the complexities of the chemistry, Jamm decided to stay close to the production process and manufacture Zubbles in the US. The first bottles rolled off the line this week. Jamm presented me with the very first case of Zubbles. And it was a very strange feeling to finally hold the product in my hand—15 years after I mixed my first batch of dishwashing detergent and food coloring.

Being an entrepreneur is a challenge any time. When your product requires complex science and engineering that adds additional challenges. It is great to see this product is now available.

Science Knowledge Quiz

Posted on July 14, 2009  Comments (4)

pew research science quiz results

Pew Research Center’s new study of science and its impact on society includes a science knowledge quiz. You can test yourself on the quiz. Thankfully I was able to get all 12 answers correct, which 10% of those taking the test have done. The median score was 8 out of 12.

I find some of the results surprising. The question most often answered correctly is “Which over-the-counter drug do doctors recommend that people take to help prevent heart attacks?”. The least often “Electrons are smaller than atoms,” a true or false question fewer than 50% of people got right.

Public Praises Science; Scientists Fault Public, Media

Americans like science. Overwhelming majorities say that science has had a positive effect on society and that science has made life easier for most people. Most also say that government investments in science, as well as engineering and technology, pay off in the long run. And scientists are very highly rated compared with members of other professions: Only members of the military and teachers are more likely to be viewed as contributing a lot to society’s well-being.
…
Just 17% of the public thinks that U.S. scientific achievements rate as the best in the world. A survey of more than 2,500 scientists, conducted in collaboration with the American Association for the Advancement of Science (AAAS), finds that nearly half (49%) rate U.S. scientific achievements as the best in the world.
…
large percentages think that government investments in basic scientific research (73%) and engineering and technology (74%) pay off in the long run. Notably, the partisan differences in these views are fairly modest, with 80% of Democrats and 68% of Republicans saying that government investments in basic science pay off in the long run. Comparable percentages of Democrats and Republicans say the same about government investments in engineering and technology.

In this regard, public views about whether funding for scientific research should be increased, decreased or kept the same have changed little since the start of the decade. Currently, more than twice as many people say that, if given the task of making up the budget for the federal government, they would increase (39%) rather than decrease (14%) funding for scientific research; 40% say they would keep spending as it is. That is largely unchanged from 2001, when 41% said they would increase funding for scientific research.

Engineering Students Increasing at Universities

Posted on April 27, 2009  Comments (0)

Engineering suddenly hot at universities

Across the United States, enrollment in engineering programs has risen to levels not seen in three decades. The recession appears to be one factor, as students and their parents look for dependable careers. But some education officials detect a shift in opinion about the profession itself, as global warming and stem-cell research make fields like chemical and bioengineering more than just wise choices for job-seekers – but fashionable ones, too.

Many students are bringing to engineering a heightened sense of social responsibility and a desire “to go out and make a difference in the world,” says Joseph Helble, dean of the Thayer School of Engineering at Dartmouth College in Hanover, N.H., where enrollment in introductory undergraduate courses is 30 percent above the five-year average.

Nationally, enrollment in undergraduate engineering programs rose 3 percent in 2007 and 4.5 percent 2008, according to the American Association of Engineering Education. Meanwhile, enrollment in masters’ degree programs rose 7 percent in 2007 and 2 percent in 2008. In the fall of 2008, 91,489 masters degree students and 403,193 undergraduates were studying engineering at US universities and colleges.

Skeptics note that engineering remains a low priority for US students: Among the 25 top engineer-producing countries, the United States ranks No. 22 on a per capita basis.

Increased engineering education is good news for future economic growth. Hopefully this trend can continue.

USA Losing Scientists and Engineers Educated in the USA

Posted on March 20, 2009  Comments (6)

The USA continues to lose ground, in retaining the relative science and engineering strength it has retained for the last 50 plus years. As I have said before this trend is nearly inevitable – the challenge for the USA is to reduce the speed of their decline in relative position.

A new open access report, Losing the World’s Best and Brightest, explores the minds of current foreign science and engineering students that are studying in the USA. This is another in the list of reports on similar topics by Vivek Wadhwa and Richard Freeman. And again they point out the long term economic losses the USA is setting up by failing to retain the talent trained at our universities. It is a problem for the USA and a great benefit for countries like India and China.

“Foreign students receive nearly 60% of all engineering doctorates and more than half of all mathematics, computer sciences, physics and economics doctorates awarded in the United States. These foreign nationals end up making jobs, not taking jobs,” said Wadhwa. “They bring insights into growing global markets and fresh ideas. Research has shown that they even end up boosting innovation by U.S. inventors. Losing them is an economic tragedy.”

According to the study’s findings, very few foreign students would like to stay in the United States permanently—only 6% of Indian, 10 percent of Chinese and 15% of Europeans. And fewer foreign students than the historical norm expressed interest in staying in the United States after they graduate. Only 58% of Indian, 54% of Chinese and 40% of European students wish to stay for several years after graduation. Previous National Science Foundation research has shown 68% of foreigners who received science and engineering doctorates stayed for extended periods of time, including 73% of those who studied computer science. The five-year minimum stay rate was 92% for Chinese students and 85% for Indian students.

The vast majority of foreign student and 85% of Indians and Chinese and 72% of Europeans are concerned about obtaining work visas. 74% of Indians, 76% of Chinese, and 58% of Europeans are also worried about obtaining jobs in their fields. Students appear to be less concerned about getting permanent-resident visas than they are about short-term jobs. Only 38% of Indian students, 55% of Chinese, and 53% of Europeans expressed concerns about obtaining permanent residency in the USA.

On the tonight show yesterday, President Obama said

we need young people, instead of — a smart kid coming out of school, instead of wanting to be an investment banker, we need them to decide they want to be an engineer, they want to be a scientist, they want to be a doctor or a teacher.

And if we’re rewarding those kinds of things that actually contribute to making things and making people’s lives better, that’s going to put our economy on solid footing. We won’t have this kind of bubble-and-bust economy that we’ve gotten so caught up in for the last several years.

Eric Schmidt, Google CEO, recently expressed his frustration with the policies discouraging science and engineering graduates staying in the USA after they complete their education.

That is a brilliant [actually not brilliant at all] strategy take the best people hire them in American universities and then kick them out” It happens. “Its shocking.” It happens. “I know we are fighting against it.” “We America remain, by far the place of choice for education, particularly higher education.”
