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.

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.

Get Your Own Science Art

hemoglobin represented in crystal

Cool science art from Bathsheba Sculpture.

The Molecule that Makes Breathing Worthwhile – Hemoglobin is the iron-bearing protein that most animals use to carry oxygen from their lungs to their muscles, or wherever it’s needed for metabolism, i.e. life. It’s the most important part of red blood cells, and its iron is what makes them red.

This sculpture, etched in a heavy 3 1/4″ glass cube, shows hemoglobin’s beautiful structure: the four heme groups each with its iron atom, the two alpha and two beta subunits, and the translucent molecular surface over all.

As well as being handsome and useful, hemoglobin is a star of scientific history. With its close relative myoglobin, it was the first protein to have its 3D structure determined by X-ray crystallography. Max Perutz and John Kendrew at Cambridge University received the Nobel Prize in 1962 for doing it.

The site offers various crystals and sculptures created by Bathsheba Grossman. The art itself is very cool and the site includes interesting information on the science represented by the art and the engineering behind creating the art.

The points are tiny (.1mm) fractures created by a focused laser beam. The conical beam, with a focal length of about 3”³, shines into the glass without damaging it except at the focal point. At that one point, concentrated energy heats the glass to the cracking point, causing a microfracture.

To draw more points, the laser is pulsed on and off. To make the beam move between points, it’s reflected from a mirror that is repositioned between pulses. The mirror is moved by computer-controlled motors, so many points can be drawn with great speed and accuracy. A typical design might use several hundred thousand points, or half a million isn’t unusual in a large block, each placed with .001”³ accuracy.

Create Your Own Book

I received a custom made photo book from my brother. It is amazing. It is a hardcover book, full of photos. The quality is amazing. The book is printed by blurb. Looking on their web site the pricing is surprisingly cheap: 150 page full color hardcover book – $39.95 (for 1 copy! – 10% discount at 25 copies…), as little as $18.95 for a full color softcover book up to 40 pages. The site says books are normally printed in under a week.

I have not tried it but it appears printing your own great looking book is about as easy as creating a blog. I knew it was getting easier to print books, but still I find this very cool. Blurb can import photos from Flickr and Picasa.

This technology enabled self publishing also brings us: The Best Writing on Science Blogs 2006, using lulu: “Lulu is fast, easy and free, No set-up fees. No minimum order. Keep control of the rights. Set your own price. Each product is printed as it is ordered. No excess inventory.”

MIT Media Lab Releases Scratch

Scratch is a new programmable toolkit that enables kids to create their own games, animated stories, and interactive art — and share their creations with one another over the Net.

Scratch is designed especially for youth at Computer Clubhouses, an international network of after-school centers in low-income communities. The Scratch project aims to create a programming culture at Computer Clubhouses, empowering youth (ages 10-16) to express themselves fluently and creatively with new technologies.

Water From Air

Magic water harvesting machine:

Amazing. A gizmo which sucks the air in, then sucks the water out of the air, and then spews out clean fresh water. 500 Gallons of it – a day.

Pretty cool. Getting clean water is a large problem throughout the world. Unfortunately this is not the solution yet – each machine costs $500,000. still for the right situations this is useful. FEMA bought 2.

Its precise workings aren’t public, but they use a chemical process similar to the one that causes salt to absorb moisture from the air (and clump up your saltshaker). The water-harvesting technology was originally the brainchild of the Pentagon’s Defense Advanced Research Projects Agency (DARPA), which sought ways to ensure sustainable water supplies for U.S. combat troops deployed in arid regions like Iraq.

Darpa gave millions to research companies like LexCarb and Sciperio to create a contraption that could capture water in the Mesopotamian desert. But it was Aqua Sciences, that was first to put a product on the market that can operate in harsh climates.

$100 Laptop Update

Green $100 Laptop photo

Public can purchase $100 laptop. I am not sure I understand the headline – this seems a more accurate picture of situation: OLPC aims for mass production in third quarter, 2007. At this time the cost each is about $150 and you will have to pay for 2 (you buy one for yourself and one for the developing world). The aim is to reach the $100 price level, but that has not quite been achieved yet.

The first countries to sign up to buying the machine, which is officially dubbed XO, include Brazil, Argentina, Uruguay, Nigeria, Libya, Pakistan and Thailand.

The XO’s software has been designed to work specifically in an educational context. It has built-in wireless networking and video conferencing so that groups of children can work together. The project is also working to ensure that children using the laptop around the world can be in contact.

The project continues to move forward even with the bumps along the road – it is quite an ambitious plan. Take a look at this great story: What kids can learn when you just give them access to a computer.

Cheap, Superefficient Solar

Technologies collectively known as concentrating photovoltaics are starting to enjoy their day in the sun, thanks to advances in solar cells, which absorb light and convert it into electricity, and the mirror- or lens-based concentrator systems that focus light on them. The technology could soon make solar power as cheap as electricity from the grid.
…
“I’d much rather make a few square miles of plastic lenses–it would cost me less–than a few square miles of silicon solar cells,” Olson says. Today solar power is still more expensive than electricity from the grid, but concentrator technology has the potential to change this. Indeed, if manufacturers can meet the challenges of ramping up production and selling, distributing, and installing the systems, their prices could easily meet prices for electricity from the grid, says solar-industry analyst Michael Rogol

Jetson Jetplane

Finally the Jetpacks we were promised by the Jetson’s 🙂 Well not really but still pretty cool. Many very cool videos (they broke link so I removed it 🙁 ) on the Jet-man website show the jetpack in action. The flight is controlled by body movements (not controls, other than the gas). To fly, currently, Yves Rossy jumps from a plane and then extends the wings turns on the jets. Some additional improvements are needed to allow Yves to achieve ground take-offs, aerobatic operations and vertical climbs.
