S&P 500 CEO’s: Engineers Stay at the Top

2008 Data from Spencer Stuart on S&P 500 CEO (link broken so it was removed, it is so sad that companies still pay people to manage web sites that don’t even understand basic web usability principles such as web pages must live forever) shows once again more have undergraduate degrees in engineering than any other field, increasing to 22% of CEO’s this year.

In 1990 Engineering majors accounted for 6% of the bachelor’s degrees in the USA (1970 5%, 1980 7%). Business accounted for 23% of the majors in 1990 (1970 14%, 1980 21%). Liberal arts 3% in 1980 (1970 1%, 1980 2%).

The report does not show the fields for the rest of the CEO’s. 39% of S&P CEOs have MBAs. 28% have other advanced degrees. The University of Wisconsin-Madison and Harvard tied for the most CEO’s with undergraduate degrees from their universities at 13. Princeton and the University of Texas had 9 and Stanford had 8.

While the CEO’s have engineering education backgrounds the work they have done is often in other functions. The top function that CEO’s that have worked in during their careers: Operations (42%), Finance (31%), Marketing (24%), Sales (17%), Engineering (11%).

Battery Breakthrough

New battery could change world

Inside Ceramatec’s wonder battery is a chunk of solid sodium metal mated to a sulphur compound by an extraordinary, paper-thin ceramic membrane. The membrane conducts ions — electrically charged particles — back and forth to generate a current. The company calculates that the battery will cram 20 to 40 kilowatt hours of energy into a package about the size of a refrigerator, and operate below 90 degrees C.

This may not startle you, but it should. It’s amazing. The most energy-dense batteries available today are huge bottles of super-hot molten sodium, swirling around at 600 degrees or so. At that temperature the material is highly conductive of electricity but it’s both toxic and corrosive. You wouldn’t want your kids around one of these.

The essence of Ceramatec‘s breakthrough is that high energy density (a lot of juice) can be achieved safely at normal temperatures and with solid components, not hot liquid.

Ceramatec says its new generation of battery would deliver a continuous flow of 5 kilowatts of electricity over four hours, with 3,650 daily discharge/recharge cycles over 10 years. With the batteries expected to sell in the neighborhood of $2,000, that translates to less than 3 cents per kilowatt hour over the battery’s life. Conventional power from the grid typically costs in the neighborhood of 8 cents per kilowatt hour.

A small three-bedroom home in Provo might average, say, 18 kWh of electric consumption per day in the summer — that’s 1,000 watts for 18 hours. A much larger home, say five bedrooms in the Grandview area, might average 80 kWh, according to Provo Power.;Either way, a supplement of 20 to 40 kWh per day is substantial. If you could produce that much power in a day — for example through solar cells on the roof — your power bills would plummet.

Ceramatec’s battery breakthrough now makes that possible.

Clyde Shepherd of Alpine is floored by the prospect. He recently installed the second of two windmills on his property that are each rated at 2.4 kilowatts continuous output. He’s searching for a battery system that can capture and store some of that for later use when it’s calm outside, but he hasn’t found a good solution.

“This changes the whole scope of things and would have a major impact on what we’re trying to do,” Shepherd said. “Something that would provide 20 kilowatts would put us near 100 percent of what we would need to be completely independent. It would save literally thousands of dollars a year.”

Very interesting stuff. If they can take it from the lab to production this could be a great thing, I would like one.

Bike Folds To Footprint of 1 Wheel

Inventor’s Bike Folds Into Its Own Wheel

Dominic Hargreaves‘s bike, The Contortionist, has been shortlisted for this year’s James Dyson Award for innovation. It may bag the young inventor £10,000.

The 24-year-old, from Battersea, London, said he wanted to create a decent folding bike after the one he was using collapsed. “I couldn’t find a folding bicycle I liked,” he added. “I wanted something that could take a bit of punishment and that you could have fun with. “So I made one myself.”

Mr Hargreaves has been in contact with various manufacturers and hopes to get the bike into production soon.

His bike lock system (see photo) won the Toyota IQ Awards.

Google Uses Only Outside Air to Cool Data Center in Belgium

Another example of what makes Google such a good engineering company. They do some spectacular things but as importantly they take many, many, many, many individual steps which when taken together make a big difference. Google’s Chiller-less Data Center

Rather than using chillers part-time, the company has eliminated them entirely in its data center near Saint-Ghislain, Belgium, which began operating in late 2008 and also features an on-site water purification facility that allows it to use water from a nearby industrial canal rather than a municipal water utility.

Year-Round Free Cooling
The climate in Belgium will support free cooling almost year-round, according to Google engineers, with temperatures rising above the acceptable range for free cooling about seven days per year on average. The average temperature in Brussels during summer reaches 66 to 71 degrees, while Google maintains its data centers at temperatures above 80 degrees.

So what happens if the weather gets hot? On those days, Google says it will turn off equipment as needed in Belgium and shift computing load to other data centers. This approach is made possible by the scope of the company’s global network of data centers, which provide the ability to shift an entire data center’s workload to other facilities.

Washing Machine Uses 90% Less Water

We wrote about the nearly waterless washing machine from Xeros previously, here are some additional details. The nearly waterless washing machine (which uses 90% less water) was developed by transferring known science to another application. After extensive R&D by University of Leeds scientists a nylon polymer was selected to absorb stains and dirt due to its unique property to become highly absorbent in humid conditions. Better still, it is highly resilient so can be re-used time after time without losing its strength.

The power of polymer cleaning
The nylon polymer has an inherent polarity that attracts stains. Think of how your white nylon garments can get dingy over time as dirt builds up on the surface despite constant washing. However, under humid conditions, the polymer changes and becomes absorbent. Dirt is not just attracted to the surface, it is absorbed into the center.

Such research in university settings, then transferred to products are a great source of economic growth and environmental improvement.

Bear Defeats Combination Bear Lock

Bear-Proof Can Is Pop-Top Picnic for a Crafty Thief

Yellow-Yellow, a 125-pound bear named for two yellow ear tags that help wildlife officials keep tabs on her, has managed to systematically decipher a complex locking system that confounds even some campers.

“She’s quite talented,” said Jamie Hogan, owner of BearVault, based in San Diego. “I’m an engineer, and if one genius bear can do it, sooner or later there might be two genius bears. We’re trying to work on a new design that we can hopefully test on her.”

His company and New York’s Department of Environmental Conservation have cautioned campers in the Adirondacks against using the BearVault because of its vulnerability here. There have been no reports of the BearVault being regularly broken into anywhere else in the country.

So last year Mr. Hogan introduced the 450, a two-pound cylinder costing about $60, and a larger version, the 500, each with a second tab. On them, a camper must press in one tab, turn the lid partway, then press the second tab to remove the lid. “We thought, ‘O.K., well, one bump didn’t work so maybe two bumps will thwart her,'” he said.

But Yellow-Yellow figured that lid out, too.

1979 “iPod” Music Player

Suspiciously Prescient Man Files Patent for iPod-Like Device in 1979 by Dan Nosowitz

Kane Kramer, an inventor by trade, came up with a gadget and music distribution service almost eerily similar to the iPod-iTunes relationship that predates it by three decades. The guy predicted details down to DRM and flash memory’s dominance.

Kramer’s device, the IXI, was flash-based, even though flash memory in 1979 only could have held about three minutes of audio, and featured a screen, four-way controls, and was about the size of a cigarette pack. Even weirder, he envisioned the creation and sale of digital music and foresaw all the good and bad that would come from this: No overhead, no inventory, but a great push for independent artists, with the risk of piracy looming large.

He predicted DRM, though he didn’t go into many specifics, and in his one concession to the time, guessed that music would be bought on coin-operated machines placed in high-traffic areas.

Moth Controlled Robot

Japanese scientists to build robot insects

Ryohei Kanzaki, a professor at Tokyo University’s Research Centre for Advanced Science and Technology, has studied insect brains for three decades and become a pioneer in the field of insect-machine hybrids.

His original and ultimate goal is to understand human brains and restore connections damaged by diseases and accidents – but to get there he has taken a very close look at insect “micro-brains”.

Insects’ tiny brains can control complex aerobatics such as catching another bug while flying, proof that they are “an excellent bundle of software” finely honed by hundreds of millions of years of evolution, Prof Kanzaki said.

In an example of ‘rewriting’ insect brain circuits, Prof Kanzaki’s team has succeeded in genetically modifying a male silkmoth so that it reacts to light instead of smell, or to the odour of a different kind of moth.

Such modifications could pave the way to creating a robo-bug which could in future sense illegal drugs several kilometres away, as well as landmines, people buried under rubble, or toxic gas, the professor said.

It is nice to be reminded of the cool research being done by professors all over the globe.
