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 Â£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.

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.

Toyota Develops Thought-controlled Wheelchair

Toyota has developed a thought-controlled wheelchair (along with Japanese government research institute, RIKEN, and Genesis Research Institute). Honda has also developed a system that allows a person to control a robot through thoughts. Both companies continue to invest in innovation and science and engineering. The story of a bad economy and bad sales for a year or two is what you read in most newspapers. The story of why Toyota and Honda will be dominant companies 20 years from now is their superior management and focus on long term success instead of short term quarterly results.

The BSI-Toyota Collaboration Center, has succeeded in developing a system which utilizes one of the fastest technologies in the world, controlling a wheelchair using brain waves in as little as 125 milliseconds (one millisecond, or ms, is equal to 1/1000 seconds.

Plans are underway to utilize this technology in a wide range of applications centered on medicine and nursing care management. R&D under consideration includes increasing the number of commands given and developing more efficient dry electrodes. So far the research has centered on brain waves related to imaginary hand and foot control. However, through further measurement and analysis it is anticipated that this system may be applied to other types of brain waves generated by various mental states and emotions.

Algae Farm Aims to Turn Carbon Dioxide Into Fuel

Dow Chemical and Algenol Biofuels, a start-up company, are set to announce Monday that they will build a demonstration plant that, if successful, would use algae to turn carbon dioxide into ethanol as a vehicle fuel or an ingredient in plastics.
…
“We give them the oxygen, we get very pure carbon dioxide, and the output is very cheap ethanol,” said Mr. Woods, who said the target price was $1 a gallon.

Algenol grows algae in “bioreactors,” troughs covered with flexible plastic and filled with saltwater. The water is saturated with carbon dioxide, to encourage growth of the algae. “It looks like a long hot dog balloon,” Mr. Woods said.
…
The company has 40 bioreactors in Florida, and as part of the demonstration project plans 3,100 of them on a 24-acre site at Dow’s Freeport, Tex., site. Among the steps still being improved is the separation of the oxygen and water from the ethanol. The Georgia Institute of Technology will work on that process, as will Membrane Technology and Research, a company in Menlo Park, Calif. The National Renewable Energy Laboratory, an Energy Department lab, will study carbon dioxide sources and their impact on the algae samples.

Algenol and its partners are planning a demonstration plant that could produce 100,000 gallons a year. The company and its partners were spending more than $50 million, said Mr. Woods, but not all of that was going into the pilot plant.

Initial proof of science was generated by Dr. John Coleman at the University of Toronto between 1989 and 1999. Since then, the process has been refined to allow algae to tolerate high heat, high salinity, and the alcohol levels present in ethanol production. This is another example of the benefit of university research and investing in science and engineering innovation.
