Six Cool Ideas

The Pollution Magnet – Eighty-two thousand people die from cancer in Bangladesh every year, many due to arsenic poisoning. But building upon her discovery of a way to get rust nanoparticles to bind to arsenic, Vicki Colvin has invented a new, astonishingly easy way to clean the water supply: SautÃ© a teaspoon of rust in a mixture of oil and lye, which breaks down the rust into nano-sized pieces. Retrieve the rust particles with a household magnet. Then immerse the rust-covered magnet into a pot of contaminated water. Pull out the arsenic. The system is up to a hundred times more efficient than existing methods, and requires no electricity or manufacturing infrastructure, so even the poorest of villagers can use it.

Depending upon government regulations, Colvin’s extraction system should go global in as few as five years. Yet ultimately, Colvin, a professor of chemistry and chemical and biomolecular engineering at Rice University, has bigger plans. She sees her method as just the first step toward developing an easy point-of-use water-purification system that would cover virtually every pollutant. The filter would have a dipstick to tell you what’s in the water and a reader to tell you what you need to add to pull it out — perhaps silver nanoparticles to kill bacteria or a protein to capture pesticides.

Robot Boats Hunt Pirates

Robot Boats Hunt High-Tech Pirates on the High-Speed Seas

The International Maritime Bureau is tracking a 14-percent increase in worldwide pirate attacks this year. And although modern-day pirates enjoy collecting their fare share of booty—they have a soft spot for communications gear—they’re just as likely to ransom an entire ship. In one particularly sobering case, hijackers killed one crew member of a Taiwan-owned vessel each month until their demands were met.

For years now, law enforcement agencies across the high seas have proposed robotic boats, or unmanned surface vessels (USVs), as a way to help deal with 21st-Century techno Black Beards. The Navy has tested at least two small, armed USV demonstrators designed to patrol harbors and defend vessels. And both the Navy and the Coast Guard have expressed interest in the Protector, a 30-ft.-long USV built by BAE Systems, Lockheed Martin and Israeli defense firm RAFAEL.

The Protector, which comes mounted with a 7.62mm machine gun, wasn’t originally intended for anti-piracy operations. But according to BAE Systems spokesperson Stephanie Moncada, the robot could easily fill that role.

Google’s Secret 10GbE Switch

Google’s Secret 10GbE Switch, interesting speculation by Andrew Schmitt:

Through conversations with multiple carrier, equipment, and component industry sources we have confirmed that Google has designed, built, and deployed homebrewed 10GbE switches for providing server interconnect within their data centers. This is very similar to Google’s efforts to build its own server computers (excellent article here). Google realized that because its computing needs were very specific, it could design and build computers that were cheaper and lower power than off the shelf alternatives. The decision to do so had a profound impact on server architecture and influenced the market’s move to lower power density solutions that Sun (JAVA) , Intel (INTC) and AMD (AMD) now embrace.

New “Cold Cathode” Fluorescents: 4 Times Longer Life, Reduced Mercury

New “Cold Cathode” Fluorescents: 85% Less Mercury

It’s a new fluorescent bulb that could have a bright future — the cold cathode fluorescent lamp (or CCFL). These bulbs contain half the mercury of conventional “hot cathode” fluorescents. They have a thinner tube diameter, which allows them to run cooler, and last up to four times as long (a lifespan of 25,000 hours). This means that the mercury is reduced by 85% over the life of a cold cathode bulb, because a regular CFL would have to be replaced three times during that period. Another big advantage of CCFLs is that they are fully dimmable, and “on/off” cycles do not shorten their life.

Google Offers $10 Million in Awards for Google Phone Development

Android is the new Google Phone platform. The Android Developers Blog has announced Google has offered $10 million in the Android Developer Challenge:

One of our goals in releasing the Android SDK is to unleash the creativity of application developers on the platform. We’d also like to get feedback early enough that we can make changes before the first Android-powered devices are available to the public. We plan to release updates to the SDK regularly which means that there will be additions and changes to the APIs and user experience — subscribe to this blog to stay up to date.

We’re really looking forward to seeing all the amazing applications that developers will create on an open mobile phone platform. In fact, you may even want to enter your application into the Android Developer Challenge — a USD$10 million challenge sponsored by Google to support and recognize developers who build great applications for the Android platform.

The award money will be distributed equally between two Android Developer Challenges:

Android Developer Challenge I: Submissions from January 2 through March 3, 2008
Android Developer Challenge II: This part will launch after the first handsets built on the platform become available in the second half of 2008

In the Android Developer Challenge I, the 50 most promising entries received by March 3 will each receive a $25,000 award to fund further development. Those selected will then be eligible for even greater recognition via ten $275,000 awards and ten $100,000 awards. Once again Google is showing they understand how to manage in the new world.

Sandwich Brick – Reusing Waste Material

A brick-through, Malaysia

at the British Invention Show 2007 held in London recently, waste material bagged Universiti Malaya (UM) researcher Asrul Mahjuddin Ressang Aminuddin a Diamond (Special Award for Earth Science). The lecturer, from UM’s Built Environment faculty, designed a “sandwich brick” that incorporated unwanted plastic, wood particles and other waste material at its core. Helping to save about 26% to 30% on construction costs, the sandwich brick promotes green architecture in the built environment.

“I first came up with the idea when I was assisting the tsunami victims in Thailand and Indonesia,” said Asrul Mahjuddin Ressang. “There was a lot of debris lying around and I wondered how if any could be used for rebuilding purposes.” The brick design has been well received by British construction companies as it is not only environmental friendly but is also entitled to tax incentives across Europe.

It also provides a solution to Britain’s hard-pressed construction industry following the ban on sand mining from riverbeds and waste accumulation that stands at 15 million tonnes in 2007 alone. The innovation impressed judges as it had better heat insulation compared to ordinary bricks and encouraged industries to rethink recycling at minimal costs.

Meanwhile, engineering faculty senior lecturer Dr Mohd Hamdi Abd Shukor received a Double Gold (Special Award for Industry) – for his work on tough synthetic bio-ceramic for bone implant technology and a minimal cutting fluid application in a pulse jet form.

Engineering Innovation in Manufacturing and the Economy

Editorial: Engineering Innovation, Milwaukee Journal Sentinel:

They are the invisible heroes in business, the men and women who make innovation possible. They are people like Mary Ann Wright at Johnson Controls in Milwaukee, the former chief engineer for the Ford Escape hybrid who is leading a team bent on establishing world leadership in hybrid battery systems.

Or Werner Zobel, a Modine Manufacturing engineer working in Germany who hatched the idea for a new cooling system that the Racine-based company believes could be revolutionary. The system uses ultra-thin layers of aluminum to dissipate heat, a breakthrough that has potential for car and truck radiators and air conditioning condensers.

Intellectual candlepower will fire the regional economy, the Milwaukee 7 regional economic development group believes. Its strategic plan relies on innovation-driven manufacturers that are heavy with engineers. But across the region, those companies say they can’t recruit enough engineers, and they worry that shortages will worsen as baby boomers retire. Complicating the picture is a shortage of visas for foreign-born engineers and increased competition from rapidly developing economies in China and India for those students even when they complete their studies in the United States.

The University of Wisconsin-Milwaukee, Marquette University and the Milwaukee School of Engineering are racing to fill the pipeline. Marquette and UWM are promising expansive new buildings and increased enrollment of both undergraduate and graduate students.

The USA continues to be by far the largest manufacturing in the world. And one important reason is the contributions provided by science and engineering (fed by strong science and engineering schools). In addition to other smart economic policies (The World Bank’s annual report on the easiest countries to do business in ranks the USA 3rd – after Singapore and New Zealand).

Home Use Vertical Axis Wind Turbine

The Windterra ECO1200 Wind Turbine is a revolutionary Vertical Axis Wind Turbine (VAWT).

Omni-directional: The ECO1200 can instantaneously accept wind from any direction as opposed to HAWTs (Horizontal Axis Wind Turbines, which require an on-board motor to rotate the unit relative to wind direction.
Turbulent-wind friendly: The ECO1200 is easily roof mountable and is less affected by turbulent air, making ECO1200 suited for areas where houses and trees may disturb airflow.
All-in-one system: The ECO 1200is a complete power-generation package, including turbine, controller/inverter, and mounting system. This system can typically be installed and ready to use in four to five hours.
Roof-top mounting: The ECO1200 is designed for roof top use, eliminating the need for a pole or tower installation that significantly increase cost and complicate routine maintenance.

Interesting looking. Based on some of the figures on their site it seems like this is still pushing the economic justification but with more and more engineers improving such similar system hopefully wind power can meet more of our energy needs over time.
