Large-Scale, Cheap Solar Electricity by Kevin Bullis

This week, Nanosolar, a startup in Palo Alto, CA, announced plans to build a production facility with the capacity to make enough solar cells annually to generate 430 megawatts. This output would represent a substantial portion of the worldwide production of solar energy.

According to Nanosolar’s CEO Martin Roscheisen, the company will be able to produce solar cells much less expensively than is done with existing photovoltaics because its new method allows for the mass-production of the devices. In fact, maintains Roscheisen, the company’s technology will eventually make solar power cost-competitive with electricity on the power grid.

Nanosolar also announced this week more than $100 million in funding from various sources, including venture firms and government grants. The company was founded in 2001 and first received seed money in 2003 from Google’s founders Larry Page and Sergey Brin.

Another Article on Engineering Shortage?

Shortage or surplus?

And the number one topic on everybody’s mind was, ‘Where we are going to find the staff to do the work that we have to do?’ ” said Doyle. “There might be rumors that there’s not a shortage, but you’re going to have a hard time convincing the CEOs of all these firms that there’s not a shortage.”
…
Doyle attributed the shortage to a number of forces. An expanding economy has created more jobs, he said. “The demand is high. The need is greater.” Baby boomers are retiring. Fewer engineering graduates seem to be entering the work force, especially in the architecture and engineering industry. Foreign-born engineers educated in the U.S. are now likely to return home to countries such as India and China where economies are growing exponentially.

Science, Engineering and Technology Graduates Paid Well

Forfás report says starting salaries for science engineering and technology graduates are amongst the highest of all Irish graduates.

Speaking at the awards ceremony Minister Martin said, “This report highlights the exciting careers and levels of opportunity open to graduates and students in the science, engineering and technology sector. These graduates and students are at the forefront of Ireland’s transition as a world leading knowledge economy, working at the cutting edge of innovation and research.
…
Across a range of qualifications from primary degree to PhD level the report shows that graduates in disciplines with a strong science and technology content tend to be better paid than graduates in other disciplines.

This is another example of countries targeting science and engineering education to improve future economic progress and the high pay of engineering graduates. Previous related posts:

Britain’s Royal Society Experiments with Open Access

Good news, the Royal Society tries open access by Stephen Pincock:

Britain’s Royal Society dipped a cautious toe into the waters of open access publishing this week, allowing authors whose papers are accepted by any of its seven journals to pay a fee and have their work made freely available on the web.

It seems to me most grants for scientific research should require open publication. I can imagine exceptions, but it seems to me that the expectation should be for open publication, in this day and age, and only allow non-open publication with a good reason.

For public funded research this open access expectation seems obvious. For private foundations in most cases I would think open access publication makes sense also. What business model is used to allow open access is not important, in my opinion. The important factor is open access, how that is accomplished is something that can be experimented with.

K-12 Engineering Outreach Programs

Interview, K12 Summer Outreach Programs Interview of Dr. Andrew Gerhart, author of K12 Summer Outreach Programs–Curriculum Comparisons Between Ages, Minorities, and Genders, by Sean Stickle.

I will point out that I, John Hunter, work for ASEE as an Information Technology Program Manager: my work on this blog is not associated with ASEE and the opinions I express are mine and not those of ASEE. This interview was done at the ASEE annual conference. The paper was an award winning paper from the ASEE conference last year. This paper and interview provide some good information for teachers interested in introducing engineering education to k-12 students.

Abstract of the paper:

Ensuring that the level of the material presented/used for a K-12 program is not too easy or too advanced can be a challenge to the instructor. Also ensuring that the material will be of interest to a variety of students (i.e., minorities, females, etc.) can be a challenge. Lawrence Technological University has two outreach programs each summer. One program, called the Summer Science Institute, is for high school juniors and seniors. The other program, called Summer Odyssey, is for middle school students.

Drilling to the Center of the Earth

The Deepest Hole by Alan Bellows:

In the 1960s the Soviet Union began a project to drill through the upper crust of the earth to reach the “mysterious area where the crust and mantle intermingle.” That project continued over 4 decades but they never were able to succeed. In order to drill at the depths they did reach they needed to engineer new drilling techniques.

Inside the project’s 200-foot-tall enclosure resides a unique drilling apparatus. Most deep-drilling rigs use a rotating shaft to bore through the ground– using a series of extensions which are incrementally added as the hole grows deeper– but such a method was unworkable with a hole as deep as Kola was planned to be. To overcome this, the Russian researchers devised a solution where only the drill bit at the end of the shaft was rotated. They accomplished this by forcing the pressurized “drilling mud”– the lubricant pumped down the drill shaft– through the specially-designed drill bit to cause it to spin.

Robot Football (Soccer)

In addition to the World Cup another international football event is taking place in Germany this month: RoboCup 2006

Researcher Founds a Robot Soccer Dynasty (including video webcast):

RoboCup is an international project to foster advances in artificial intelligence and intelligent robotics research. The ultimate goal of RoboCup is to develop, by 2050, a team of fully autonomous humanoid robots that can beat the human world champion soccer team. Veloso and Carnegie Mellon have been participating since “pre-RoboCup” events in 1996 and the first official RoboCup games in 1997. Veloso was general chair of RoboCup 2001 in Seattle.

Gecko Tape

Gecko TapeSticking Around with Gecko Tape:

The tape is a simple version of the adhesive on a gecko’s feet. The soles of the lizard’s feet are covered with millions of tiny little hairs, too small to see with the naked eye. The molecules in these hairs snuggle up to the molecules of any surface the gecko walks on. The molecules are attracted to each other, forming a temporary bond that keeps the gecko firmly in place.

MIT Hosts Student Vehicle Design Summit

Solar concept car drawing

Student summit set on vehicle design by Deborah Halbe

Seventy-three students from 21 universities around the world will gather at MIT this summer to design and build between five and 10 commuter vehicles that exploit human power, biofuels, solar technologies and fuel cells to travel at least 500 miles per gallon of fuel.
…
An added goal for the June 13-Aug. 13 program is to lay a foundation for ongoing multidisciplinary transportation research involving all five MIT schools. “We hope to create a project-based, socially conscious engineering curriculum for the ’06-’07 academic year,” said Anna S. Jaffe, a junior in civil and environmental engineering and one of the summit student organizers.

Malaysia Looking to Learn from India

Lessons from India’s Success in IT Industry

Infosys alone has hired 300,000 fresh engineering graduates in the various disciplines so far this year and plans to take in another 140,000.

They will undergo a 14-month IT course designed to meet the current requirements of the relevant industries.

The numbers of new hires is amazing (update – see comments, in fact the numbers are not for Infosys. According to Bloomberg:

India’s biggest software makers, hired about 229,000 workers in India in the year to March 31, according to National Association of Software and Service Companies, or Nasscom. Tata Consultancy plans to add 30,500 jobs this year and Infosys 25,000, the companies said separately in April.).
