Arctic Seed Vault Design

‘Doomsday’ vault design unveiled

he Svalbard International Seed Vault will be built into a mountainside on a remote island near the North Pole. The vault aims to safeguard the world’s agriculture from future catastrophes, such as nuclear war, asteroid strikes and climate change. Construction begins in March, and the seed bank is scheduled to open in 2008. The Norwegian government is paying the $5m (£2.5m) construction costs of the vault, which will have enough space to house three million seed samples.

Dr Fowler said Svalbard, 1,000km (621 miles) north of mainland Norway, was chosen as the location for the vault because it was very remote and it also offered the level of stability required for the long-term project. “We looked very far into the future. We looked at radiation levels inside the mountain, and we looked at the area’s geological structure,” he told BBC News. “We also modelled climate change in a drastic form 200 years into future, which included the melting of ice sheets at the North and South Poles, and Greenland, to make sure that this site was above the resulting water level.”

Engineers – Changing Career Needs

Are US engineers up to the global challenge?

Does our existing pool of engineers have the skills for today’s jobs? “If technological change is moving faster, as most people claim, then the obsolescence cycles are probably getting shorter,” says Hira. Quoting William A. Wulf, president of the National Academy of Engineering (NAE), Hira notes that the half-life of an engineer has gotten shorter. This means that continuing education is more critical for engineers than ever before. But the support mechanism of company subsidies has been largely dismantled because employees stay in jobs for shorter durations and companies no longer see benefit in paying tuition. It also means that companies, when they can, likely favor recent graduates over mid-career or older ones.

World’s Largest Dry-Transport Ship

Blue Marlin Transport Ship photo

Blue Marlin world’s largest dry-transport vessel:

For widening the beam of the Blue Marlin from 42 to 63 meter, 130 block steel sections were produced, which started on 2 May 2003 and finished at the end of October. The total weight was approx. 8,300 tons. The blocks were pre-assembled to bigger blocks before installation and the total number of blocks ready for installation in drydock was reduced to 58 blocks. The erection of the blocks in the drydocks started on 1 September 2003. The starboard blocks first. The middle blocks of each side were assembled in three units of each approx. 35 meter long. Each unit with a total weight of 800 to 1000 tons.

Educational Institutions Economic Impact

I believe investing in creating an environment where science and engineering endeavors will flourish will greatly benefit the economy. Some previous posts discussing these ideas include: Great Engineering Schools and Entrepreneurism, Engineering Future Economic Success, Science Research and the Economy and China’s Economic Science Experiment.

Wisconsin’s effort is hardly unique, but I grew up in Madison and my father taught Chemical Engineering, Statistics, and more at the UW so I pay attention to the efforts in Madison. The Wisconsin Alumni Research Foundation has been one of the most successful attempts to take academic work and create successful business efforts to benefit the university, the professors and the economy overall. Their mission: “Moving inventions arising from the university’s laboratories to the marketplace for the benefit of the university, the inventors and society.”

Building Wisconsin’s Economy illustrates how the University of Wisconsin at Madison attempts to focus on creating economic benefit, which I think is a good idea. Economic benefit is not the only purpose, but it is worthy of focus.

Zero Ink Printing

Zink – zero ink printing:

Dye crystals are embedded in the ZINK paper and are activated by heat from a ZINK printer. The crystals then colorize, producing high quality, long-lasting, durable, and affordable images.

The ZINK printing technology will enable a new mobile printing market. Later this year, ZINK Imaging’s partners will launch the first products using ZINK technology. These products are designed to take printing where it has never before been possible – into the pocket of every camera phone and digital camera user.

This is from a company press release but it sounds interesting. A digital son of Polaroid:

The Zink technology also uses heat, but the dyes are embedded into the paper itself — hence the company’s name, which stands for zero ink. Bonded inside the paper are three dye layers, colored yellow, magenta, and cyan, a shade of blue. Properly mixed, these three colors can produce the entire spectrum. Each of the dyes is in crystalline form, and each is formulated to melt into liquid at a certain temperature.

A Zink printer pulls the special paper under a thermal print head. This device has hundreds of heating elements that can each heat a tiny portion of the paper. The Zink software controls the print head, so that its heat pulses activate the correct dye colors and produce the finished photograph. A single photo can be cranked out in about a minute, at a cost of about 25 cents.

Nanotech Engine Research

Tiny engine boosts nanotech hopes:

Scientists at the University of Edinburgh have created a tiny engine powered by light that can be made to sort molecules. The device may one day find a role in nano-scale machines. It emerged from research into similar tiny machines in nature that power well known processes such as photosynthesis.

“We have a new motor mechanism for a nanomachine,” said Prof Leigh. “It is a machine mechanism that is going to take molecular machines a step forward to the realisation of the future world of nanotechnology,” he said. Because the rotaxane can be made to do useful work in a predictable fashion, ie sort particles, it could become a key component for anyone designing nano-scale device.

DivX LEGO Sumo Robotic Championship – Round 2

DivX is a proprietary video player which can be downloaded for free. The quality of the videos is great which is offset by the annoyance of having to download another plugin to view the videos. The improved quality is quite nice though it does seem a bit buggy still. See more such videos via their No Screwdriver Needed channel.

Engineering a Start-up

Engineering a start-up at University of California at San Diego:

Fifteen von Liebig-supported projects have been converted into startup companies. In the past two years alone, start-up companies that received von Liebig support have raised more than $10 million in capital. And even more discoveries have been licensed to telecommunications, biotechnology and other industry companies that are using the UCSD science to make new products or make their existing products better.

The center, started with a $10 million grant, has awarded a total of $2.4 million to 56 projects. An additional 25 projects have benefited from the center’s advisers. The return on investment has climbed steadily. The revenue UCSD received from the commercialization of discoveries out of the Jacobs School of Engineering has grown from $57,563 in 1999 to $602,713 in 2004, the most recent year for which figures were available.

Great stuff – this is the kind of thing that allows the ingenuity of engineers to benefit the economy and the engineers. Small focused efforts like this can have a huge long term impact, I believe. For those interested in building economic advantage through engineering education creating an entrepreneurial environment is a very important factor.

Leah Jamieson on the Future of Engineering Education

Leah Jamieson’s address, 2007 IEEE President and dean of the Purdue Engineering school, to DesignCon 2007. (link broken by DesignCon, so removed. How are organizations that seek to have people come to them to learn how to adopt good engineering practices still failing to basic things like keeping urls live forever?).

The future of engineering education: More questions than answers by Michael Santarini:

In addition, many academics estimate that the half-life of engineering knowledge is between two to seven years, Jamieson said. “I can tell you for us at the universities, if it’s less than five or certainly less than four [years] we’re going to get scared because it means students come in as freshmen and by the time they are done, half of what we’ve done for those first couple of years may or may not be relevant?” she said. “It’s a frightening thought, and so it means we have to keep asking ourselves, what are the parts that stay relevant, so that in fact the education is current after the students graduate or at least current on the day they do graduate.”

2007 Grainger Challenge Prize for Sustainability

2007 Grainger Challenge Prize for Sustainability:

The National Academy of Engineering (NAE) announced today the winners of the 2007 Grainger Challenge Prize for Sustainability. The contest sought innovative solutions for removing arsenic from drinking water that is slowly poisoning tens of millions of people in developing countries. Three prizes will be awarded from a field of more than 70 entries.

The Gold Award-winning SONO filter is a point-of-use method for removing arsenic from drinking water. A top bucket is filled with locally available coarse river sand and a composite iron matrix (CIM). The sand filters coarse particles and imparts mechanical stability, while the CIM removes inorganic arsenic. The water then flows into a second bucket where it again filters through coarse river sand, then wood charcoal to remove organics, and finally through fine river sand and wet brick chips to remove fine particles and stabilize water flow. The SONO filter is now manufactured and used in Bangladesh.

The system developed by the Silver Award-winning team is applied at a community’s well head. Each arsenic removal unit serves about 300 households. Water is hand-pumped into a fixed-bed column, where it passes through activated alumina or hybrid anion exchanger (HAIX) to remove the arsenic. After passing through a chamber of graded gravel to remove particulates, the water is ready to drink. This system has been used in 160 locations in West Bengal, India. The water treatment units, including the activated alumina sorbent, are being manufactured in India, and villagers are responsible for their upkeep and day-to-day operation. The active media are regenerated for re-use, and arsenic-laden sludge is contained in an environmentally safe manner with minimum leaching.
