sOccket: Power Through Play

In a fun example of appropriate technology and innovation 4 college students have created a football (soccer ball) that is charged as you play with it. The ball uses an inductive coil mechanism to generate energy, thanks in part to a novel Engineering Sciences course, Idea Translation. They are beta testing the ball in Africa: the current prototypes can provide light 3 hours of LED light after less than 10 minutes of play. Jessica Matthews ’10, Jessica Lin ’09, Hemali Thakkara ’11 and Julia Silverman ’10 (see photo) created the eco-friendly ball when they all were undergraduates at Harvard College.

They received funding from: Harvard Institute for Global Health and the Clinton Global Initiative University. The

sOccket won the Popular Mechanics Breakthrough Award, which recognizes the innovators and products poised to change the world. A future model could be used to charge a cell phone.

From Take part: approximately 1.5 billion people worldwide use kerosene to light their homes. “Not only is kerosene expensive, but its flames are dangerous and the smoke poses serious health risks,” says Lin. Respiratory infections account for the largest percentage of childhood deaths in developing nations—more than AIDS and malaria.

Letting Children Learn – Hole in the Wall Computers

The hole in the wall experiments are exactly the kind of thing I love to lean about. I wrote about them in 2006, what kids can learn.

Research finding from the Hole in the Wall foundation:

Over the 4 year research phase (2000-2004), HiWEL has extensively studied the impact of Learning Stations on children. Hole-in-the-Wall Learning Stations were installed in diverse settings, the impact of interventions was monitored and data was continually gathered, analyzed and interpreted. Rigorous assessments were conducted to measure academic achievement, behaviour, personality profile, computer literacy and correlations with socio-economic indicators.
…
The sociometric survey found:

Self-organizing groups of children who organize themselves into Leaders (experts), Connectors and Novice groups.
Leaders and Connectors identified seem to display an ability to connect with and teach other users.
Key leaders on receiving targeted intervention, play a key role in bringing about a “multiplier effect in learning” within the community.
Often girls are seen to take on the role of Connector, who initiates younger children and siblings (usually novices with little or no exposure to computers) and connects them to the leaders in the group

I believe traditional education is helpful. I believe people are “wired” to learn. They want to learn. We need to create environments that let them learn. We need to avoid crushing the desire to learn (stop de-motivating people).

If you want to get right to talking about the hole in the wall experiments, skip to the 8 minute mark.

New Server Uses 75% Less Power and Space

SeaMicro drops an atom bomb on the server industry

[SeaMicro] has created a server with 512 Intel Atom chips that gets supercomputer performance but uses 75 percent less power and space than current servers.
…
Today’s servers are so inefficient when it comes to being properly utilized,” Feldman said. “This misalignment between the server and the work load is the root of the power consumption problem.”

So SeaMicro guessed that servers could benefit instead by using lots of smaller processors, and it got lucky when Intel started promoting its low-power, low-cost Atom chip for netbooks. That lowered power consumption, since Atom processors deliver three times the performance per watt versus Intel’s server chips.
…
But SeaMicro also attacked the power consumption in the rest of the system, which accounts for about two thirds of the power consumed by a server.
…
it applied the concept of virtualization to the inside of a server. Feldman designed custom chips that could take the tasks that were handled by everything beyond the Intel microprocessor and its chip set. The custom chips virtualize all of those other components so that it finds the resource when it’s needed. It essentially tricks the microprocessor into thinking that the rest of the system is there when it needs it.

SeaMicro virtualized a lot of functions that took up a lot of space inside each server in a rack. It also did the same with functions such as storage, networking, server management and load balancing. Full told, SeaMicro eliminates 90 percent of the components from a system board. SeaMicro calls this CPU/IO virtualization. With it, SeaMicro shrinks the size of the system board from a pizza box to the size of a credit card.
…
This advance is coming just in time. Google said recently that if current power trends continue, the cost of energy consumed by a server during its three-year life span could surpass the initial purchase cost for the hardware. The Environmental Protection Agency reports that volume servers consume more than 1 percent of the total electricity in the US—representing billions of dollars in wasted operating expense each year.

Green Technology Innovation by College Engineering Students

With prizes totaling more than $100,000 in value, this year’s Climate Leadership Challenge is believed to be the most lucrative college or university competition of its kind in the country. The contest was open to all UW-Madison students.

A device that would help provide electricity efficiently and at low cost in rural areas of developing countries took the top prize – $50,000 – this week in a student competition at the University of Wisconsin-Madison for innovative ideas to counteract climate change.

The “microformer” is the brainchild of Jonathan Lee, Dan Ludois, and Patricio Mendoza, all graduate students in electrical engineering. Besides the cash prize, they will receive a promotional trip worth $5,000 and an option for a free one-year lease in the University Research Park’s new Metro Innovation Center on Madison’s east side.

“We really want to see implementation of the best ideas offered,” said Tracey Holloway, director of the Nelson Institute Center for Sustainability and the Global Environment at UW-Madison, which staged the contest for the second year in a row. “The purpose of this competition is to make an impact on climate change.”

The runner-up for the “most action-ready idea” was a proposal to promote the use of oil from Jatropha curcas plants to fuel special cooking stoves in places like Haiti. UW-Madison seniors Eyleen Chou (mechanical engineering), Jason Lohr (electrical engineering), Tyler Lark (biomedical engineering/mathematics) won $10,000 for their scheme to reduce deforestation by lowering demand for wood charcoal as a cooking fuel.

CORE Concept, a technology that would cut emissions from internal combustion engines by using a greater variety of fuels, won mechanical engineering doctoral students Sage Kokjohn, Derek Splitter, and Reed Hanson $15,000 as the “most innovative technical solution.”

SnowShoe, a smart phone application that would enable shoppers to check the carbon footprint of any item in a grocery store by scanning its bar code, won $15,000 as the “most innovative non-technical solution.” Graduate students Claus Moberg (atmospheric and oceanic science), Jami Morton (environment and resources), and Matt Leudtke (civil and environmental engineering) submitted the idea.

Other finalists were REDCASH, a plan to recycle desalination wastewater for carbon sequestration and hydrogen fuel production, by doctoral student Eric Downes (biophysics) and senior Ian Olson (physics/engineering physics); and Switch, an energy management system that integrates feedback and incentives into social gaming to reduce personal energy use, by doctoral students David Zaks (environment and resources) and Elizabeth Bagley (environment and resources/educational psychology).

Using Bacteria to Power Microscopic Machines

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Northwestern University have discovered that common bacteria can turn microgears when suspended in a solution, providing insights for designs of bio-inspired dynamically adaptive materials for energy.

“The ability to harness and control the power of bacterial motion is an important requirement for further development of hybrid biomechanical systems driven by microorganisms,” said Argonne physicist and principal investigator Igor Aronson. “In this system, the gears are a million times more massive than the bacteria.”

A few hundred bacteria work together in order to turn the gear. When multiple gears are placed in the solution with the spokes connected as in a clock, the bacteria will turn both gears in opposite directions, causing the gears to rotate in synchrony—even for long stretches of time.

“There exists a wide gap between man-made hard materials and living tissues; biological materials, unlike steel or plastics, are ‘alive,'” Aronson said. “Our discovery demonstrates how microscopic swimming agents, such as bacteria or man-made nanorobots, in combination with hard materials, can constitute a ‘smart material’ which can dynamically alter its microstructures, repair damage, or power microdevices.”

IBM Fellow Grady Booch on the Value of Engineering?

In this webcast IBM Fellow Grady Booch discusses the critical role engineering plays in moving society forward. And he explores the history of science and engineering. This interesting webcast would be a good video to show children, or anyone, to bring out the desire to study engineering and encourage them to study so they can join the many engineers shaping our world and our future.

Innovation, America and Engineering: NAE Grand Challenges Summit

Innovation, America and Engineering: NAE Grand Challenges Summit in Raleigh, North Carolina:

Friday morning in Raleigh, a group of engineers from industry, academia and even government met to discuss the threat of America losing its global lead in innovation. The panel discussion was part of a Summit on the National Academy of Engineering Grand Challenges…

Jeff Wadsworth, CEO and president of Battelle Memorial Institute, noted that high school graduation rates have fallen from about 86 percent in the Baby Boomer generation to about 72 percent today. He compared that to a 96 percent graduation rate in Denmark, 92 percent in Japan and the fact that China graduates three engineering students for every one that we do. It’s not news that international competition is stiffening against us, but the statistics he presented about how the U.S. measures up to foreign countries in K-12 metrics was gut-wrenching.

“Our historic lead in secondary education has disappeared,” Wadsworth said. “And as a leader of a large organization, I worry about education.”
…
Another panelist, Senator Ted Kaufman (D-Delaware) said the country was at a critical point in history. “We are in an economic war,” he said. “The future of our country rests on our ability to use STEM to solve problems.” Kauffman is the only sitting senator in Congress to have worked in the engineering field, and he repeatedly drummed out a message that policy could drive a solution to the STEM crisis.
…
A third panelist – John Chambers, chairman and CEO of CISCO – said he believed changing teaching methods in K-12 settings to be more collaborative, projects-oriented and skills-mastery oriented would be a good starting point.
…
the deans of the engineering colleges at both Duke and NC State universities announced today a new nationwide program targeting attracting school-aged children to the STEM fields. The Grand Challenge K-12 Partners Program will lean on engineering colleges throughout the U.S. to be resource hubs for K-12 students and teachers in their region.
…
Three more NAE Grand Challenge Summits are scheduled to take place next month, in Phoenix, Chicago and Boston. A fourth is scheduled for Seattle in May.

The importance of innovation and engineering education to long term economic success is one thing I believe strongly in and have written about here: Engineering Economic Benefits, Techonolgy Innovation Global Economy Changing, Centers of Technical Excellence and Economic Power. And is one reason I work for the American Society of Engineering Education (this blog is my own and not associated with ASEE).

Steve Jobs introduces the Apple iPad. A touch screen tablet with wireless internet connectivity and a touch screen keyboard (when desired).

Siftable Modular Computers

Pretty cool. I must admit I don’t really see how this would function outside of specifically designed situation. I can imagine it could be very cool for education, especially of young kids. Siftables act in concert to form a single interface: users physically manipulate them – piling, grouping, sorting – to interact with digital information and media. David Merrill and Jeevan Kalanithi originally created Siftables at the MIT Media Lab and have formed a company to commercialize the product and have received a grant from NSF to continue the work.
