The amazing man who drives a car with thought-powered prosthetic arms.

source: http://www.dailymail.co.uk/

A former mechanic who lost his arms in an industrial accident four years ago is able to drive again thanks to thought-powered artificial limbs.

Christian Kandlbauer, who lost his arms after being electrocuted by 20,000 volts, retook his driving test and passed.

Using the nerves that previously controlled the healthy limbs, the 22-year-old Austrian merely has to think what he wants his arms to do and the command is obeyed.

The thought from his brain creates a particular electrical impulse in the nerve endings at the site of amputation.

Those impulses are picked up by electrical connections to the artificial arm, which respond to the specific impulse and so causing the arm to move as he wants.

Mr Kandlbauer, who became the first recipient in the world of such ‘intelligent’ artificial limbs two years ago, now drives to work in a modified disabled car after passing his test last week.

‘The driving is really important to me,’ he said. ‘But now I can also drink a glass of beer without needing a straw. Now that’s impressive!’

He will be in the German capital Berlin on Friday to further showcase his abilities with his arms after they were fitted in 2007.

Before being fitted, the apprentice, who lost his arms in September 2005, underwent a complex operation in which nerves are relocated.

The Otto Bock health care company invented in the prosthetics in conjunction with medical scientists in Vienna.

‘After this selected nerve transfer surgery, the signals that were once responsible for controlling the arm are used for controlling the new prosthesis,’ said the makers of his arms.

‘Electrodes installed in the socket of the prosthesis respond to these control signals. When the user sends movement signals, a complex electronic analysis inside the prosthesis converts the signals and recognises the movements the user would like to make.’

He now works as a warehouse clerk at the company where he was employed as a mechanic before his accident.

50,000 soldiers believed buried by a cataclysmic sandstorm in 525 B.C. may have been found.


The remains of a mighty Persian army said to have drowned in the sands of the western Egyptian desert 2,500 years ago might have been finally located, solving one of archaeology's biggest outstanding mysteries, according to Italian archaeologists.

Bronze weapons, a silver bracelet, an earring and hundreds of human bones found in the vast desolate wilderness of the Sahara desert have raised hopes of finally finding the lost army — 50,000 strong — of Persian King Cambyses II, buried by a cataclysmic sandstorm in 525 B.C.

"We have found the first archaeological evidence of a story reported by the Greek historian Herodotus," Dario Del Bufalo, a member of the expedition from the University of Lecce, told Discovery News.

According to Herodotus (484-425 B.C.), Cambyses, the son of Cyrus the Great, sent 50,000 soldiers from Thebes to attack the Oasis of Siwa and destroy the oracle at the Temple of Amun. Alexander the Great had famously sought legitimization of his rule from the oracle of Amun in 332 B.C., but according to legend, the oracle would have predicted the death of Cambyses.

After walking for seven days in the desert, the army got to an "oasis," which historians believe was El-Kharga. After they left, they were never seen again.

"A wind arose from the south, strong and deadly, bringing with it vast columns of whirling sand, which entirely covered up the troops and caused them wholly to disappear," wrote Herodotus.

As no trace of the hapless warriors has ever be found, scholars began to dismiss the story as a fanciful tale.

Now, two top Italian archaeologists claim to have found striking evidence that the Persian army was indeed swallowed in a sandstorm. Twin brothers Angelo and Alfredo Castiglioni are already famous for their discovery 20 years ago of the ancient Egyptian "city of gold" Berenike Panchrysos.

Presented recently at the archaeological film festival of Rovereto, the discovery is the result of 13 years of research and five expeditions to the desert.

"It all started in 1996, during an expedition aimed at investigating the presence of iron meteorites near Bahrin, one small oasis not far from Siwa," Alfredo Castiglioni, director of the Eastern Desert Research Center (CeRDO)in Varese, told Discovery News.

While working in the area, the researchers noticed a half-buried pot and some human remains. Then the brothers spotted something really intriguing — what could have been a natural shelter.

It was a rock about 114.8 feet long, 5.9 feet in height and 9.8 feet deep. Such natural formations occur in the desert, but this large rock was the only one in a large area.

"Its size and shape made it the perfect refuge in a sandstorm," Castiglioni said.

Right there, the metal detector of Egyptian geologist Aly Barakat of Cairo University located relics of ancient warfare: a bronze dagger and several arrow tips.

"We are talking of small items, but they are extremely important as they are the first Achaemenid objects, thus dating to Cambyses' time, which have emerged from the desert sands in a location quite close to Siwa," Castiglioni said.

About a quarter mile from the natural shelter, the Castiglioni team found a silver bracelet, an earring and few spheres which were likely part of a necklace.

"An analysis of the earring, based on photographs, indicate that it certainly dates to the Achaemenid period. Both the earring and the spheres appear to be made of silver. Indeed a very similar earring, dating to the fifth century B.C., has been found in a dig in Turkey," Andrea Cagnetti, a leading expert of ancient jewelry, told Discovery News.

In the following years, the Castiglioni brothers studied ancient maps and came to the conclusion that Cambyses' army did not take the widely believed caravan route via the Dakhla Oasis and Farafra Oasis.

"Since the 19th century, many archaeologists and explorers have searched for the lost army along that route. They found nothing. We hypothesized a different itinerary, coming from south. Indeed we found that such a route already existed in the 18th Dynasty," Castiglioni said.

According to Castiglioni, from El Kargha the army took a westerly route to Gilf El Kebir, passing through the Wadi Abd el Melik, then headed north toward Siwa.

"This route had the advantage of taking the enemy aback. Moreover, the army could march undisturbed. On the contrary, since the oasis on the other route were controlled by the Egyptians, the army would have had to fight at each oasis," Castiglioni said.

To test their hypothesis, the Castiglioni brothers did geological surveys along that alternative route. They found desiccated water sources and artificial wells made of hundreds of water pots buried in the sand. Such water sources could have made a march in the desert possible.

"Termoluminescence has dated the pottery to 2,500 years ago, which is in line with Cambyses' time," Castiglioni said.

In their last expedition in 2002, the Castiglioni brothers returned to the location of their initial discovery. Right there, some 62 miles south of Siwa, ancient maps had erroneously located the temple of Amun.

The soldiers believed they had reached their destination, but instead they found the khamsin -- the hot, strong, unpredictable southeasterly wind that blows from the Sahara desert over Egypt.

"Some soldiers found refuge under that natural shelter, other dispersed in various directions. Some might have reached the lake of Sitra, thus surviving," Castiglioni said.

At the end of their expedition, the team decided to investigate Bedouin stories about thousands of white bones that would have emerged decades ago during particular wind conditions in a nearby area.

Indeed, they found a mass grave with hundreds of bleached bones and skulls.

"We learned that the remains had been exposed by tomb robbers and that a beautiful sword which was found among the bones was sold to American tourists," Castiglioni said.

Among the bones, a number of Persian arrow heads and a horse bit, identical to one appearing in a depiction of an ancient Persian horse, emerged.

"In the desolate wilderness of the desert, we have found the most precise location where the tragedy occurred," Del Bufalo said.

The team communicated their finding to the Geological Survey of Egypt and gave the recovered objects to the Egyptian authorities.

"We never heard back. I'm sure that the lost army is buried somewhere around the area we surveyed, perhaps under 16.4 feet of sand."

Piero Pruneti, editor of Archeologia Viva, Italy's most important archaeology magazine, is impressed by the team's work.

"Judging from their documentary, their hypothesis of an alternative route is very plausible," Prunetic told Discovery News. "Indeed, the Castiglioni's expeditions are all based on a careful study of the landscape...An in-depth exploration of the area is certainly needed!"

IP Sensor Appliance from Mamac

Case Study: Grove City College

College Finds Solution for Remote Building Monitoring and Control
Web-Based Appliance Extends Reach of Maintenance Staff

“This is a technology we need to be using.” That’s the conclusion of James Wendelschaefer at Grove City College regarding a novel solution for remote building sensing, alarming and control. The school, a small highly regarded college in western Pennsylvania, is approximately an hour north of Pittsburgh and has an enrollment of about 2,300. Wendelschaefer is the director of the physical plant for the school, which has a history reaching back to 1876. The college is known for its commitment to Christian principles and its rigorous emphasis on cultural literacy and liberal studies.

Small Staff, Many Buildings

According to Wendelschaefer, the attractive hilly campus encompasses 30 buildings, most with heating and cooling systems. Some of the campus buildings are served by a central steam and chilled water plant. Others, notably the main administrative building, Crawford Hall, have independent systems. The challenge that faces Wendelschaefer is that his campus maintenance staff has only two HVAC specialists. He smiles, “Sometimes we’re stretched pretty thin.”

He explains that the physical plant department looks for ways to work more efficiently. One continuing challenge is the need for staff to make numerous trips to outlying campus buildings to adjust thermostats, check equipment and respond to changing needs of building occupants. An example he gives is the school’s football field house, which is heated throughout the football season.

The temperature is set down after the season is complete. “But numerous times in the winter and early spring, the athletic department has recruiting prospects visiting, or has other short-term events going on, so they want the heat brought up.”

Building Visits Consume Staff Time

“Each time, a physical plant staffer has to drive down to the field house and set up the temperature, then later set it back down.” Wendelschaefer notes that each trip takes staff time and takes people away from other necessary work. He adds, “This is just one example of the kinds of tasks we have with building temperature set points. A standard setback thermostat wouldn’t help because the changes are often irregular. Plus, we need to periodically check the operation status of the individual building heating and cooling systems.”

Wendelschaefer discussed these issues with Jim Jancse, manager of the service division of Renick Brothers Mechanical Contractor, Inc., of Slippery Rock, Pennsylvania. Jancse is a controls specialist and had just learned about a new web-based device for remote system control, which he brought to Wendelschaefer’s attention. Jancse also talked with his distributor’s representative, Ken Smyers, sales engineer from the Edward C. Smyers Co. of Pittsburgh, and they concluded that Jancse’s idea had merit.

New Concept Studied

The concept was to use a web-based control appliance called Maverick, manufactured by MAMAC Systems, Inc., of Minneapolis. This newly introduced tool can be installed anywhere there is an internet connection. It accepts digital and analog inputs from a wide range of sensors. It also has relay outputs that can control a wide range of devices.

The appliance is about the size of a programmable thermostat and can be mounted anywhere in the building. It simply requires an Ethernet connection to the internet. No dedicated computer is required because the appliance has an on-board web server. Most college buildings have this type of internet service. Wendelschaefer was immediately interested in trying the device, and has a trial unit installed in his office suite in Crawford Hall.

Comfort Settings Adjusted Remotely

This unit monitors space temperature, and can check the functionality of the air handler that serves the space. Comfort settings can be adjusted, and the unit is designed to send an e-mail alert if preset comfort parameters are exceeded. The alert can go to any online computer, PDA, or even a cell phone with text messaging.

Ironically, the Maverick unit was installed above a suspended ceiling in an office space where there had previously been water damage from an air handler freeze-up that hadn’t been detected until the pipes burst. According to Smyers and Jancse, this is exactly the kind of problem the online alarming feature can help prevent. Wendelschaefer saw the capabilities and was immediately impressed.

Sees Immediate Applications

He explains that some of the newer buildings on campus have automation systems with DDC control. “But there are other buildings, typically smaller and older buildings that have no control systems, just thermostats. I see these as targets.” He notes that from what he’s seen in brief trial with the Maverick, there are at least six buildings that could be fitted with such systems right away.

In addition to the buildings on the contiguous campus, there are other college facilities that are some distance away. Examples are an observatory 60 miles north in Edinboro, Pennsylvania, and a bookstore 60 miles south in Pittsburgh. Wendelschaefer currently intends to equip both facilities with the web-based appliances. “There’s a real benefit here where otherwise you’d have to take someone off the campus for a half-day just to do an equipment check or to change settings.”

Meets College Efficiency Goal

“It’s just the right thing to do. It saves labor, saves vehicle fuel, and saves energy.” Wendelschaefer notes that the college places a high priority on energy efficiency, and the Maverick appliance enhances this strategy. “For example,” he says, “we can quickly set down the comfort settings for dorm rooms during school breaks, but can override this when we have the dorms occupied by other visitors. We can even use this system to control water heating and architectural lighting.”

According to Ken Smyers, Wendelschaefer’s enthusiastic reception of the web-based appliance is not unusual. “I’m hearing this from other people, too. This system fills a gap that has existed for a long time between full building automation systems and thermostats.” Smyers explains that, as at Grove City College, operators of other small- and medium-sized buildings often feel they can’t justify the expense -- $10,000 to $50,000 – for a full automation system. Such a system may have a long or non-existent payback.

Meets a Critical Need

But these operators badly want remote status information and alarming, and they want to be able to take a few simple steps to initiate equipment operations. They also would like to be able to remotely adjust scheduling for building comfort systems. An internet appliance like the Maverick gives them that option for a few thousand dollars or less for the entire installation.

Smyers also points out that full automation systems usually require a significant amount of training of a dedicated staff person. “But systems like the Maverick are so easy to set up and use, and very little training is required.” As an example, he points to Grove City College, where the tentative plan is for the administrative staff member who books dorm rooms for off-session use will, as part of his/her routine, schedule the comfort system to come on when the room is occupied.

Still Finding New Applications

Smyers and Jancse both point out that this approach doesn’t meet the needs of every building. Jancse says, “There are, of course, facilities where a full automation system is the best way to go. But for a lot of applications, this is a great solution.” As with any new technological solution, owners are still finding new applications, new approaches. Wendelschaefer says, “The opportunities with this – it just makes you start to think. You are limited only by your ingenuity.”

October is Energy Awareness Month

Have you ever wondered how powerful you are? Not the power of fame, fortune or knowledge, but how much power is in your body. On average, a human consumes about 3,300 watt-hours of energy every day but has the potential to produce more than three times that amount - up to 11,000 watt-hours of power - from normal bodily functions such as motion and the production of body heat. Walking, for example, produces 163 watts of power, while sprinting generates more than 1,600 watts. What if this wattage could be turned into usable energy?

Let's look at how the principle works in a motion such as walking. A single footstep causes pe4ressure when the foot hits the floor. When the flooring is engineered with piezoelectric technology, the electrical charge produced by that pressure is captured by floor sensors, converted to an electrical charge by piezo materials (usually in the form of crystals or ceramics), then sorted and used as a power source.

In 2007, two MIT graduate students proposed the idea of installing piezoelectric flooring in urban areas. Dubbed "Crowd Farming," the idea was to install a flooring system that would take advantage of piezoelectric principles by harvesting power from footsteps in crowded places such as train stations, malls, concerts and anywhere where large groups of people move. The key is the crowd: One footstep can only provide enough electrical current to light two 60-watt bulbs for one second, bu tthe greater the number of people wlalking across the piezoelectric floor, the greater amounts of power produced. It's not beyond the realm of possibility - approximately 28,500 footsteps generate energy to power a train for one second. Imagine what the combined power of commuters' footsteps during rush hour could do.

A new experiment in using human waste as fuel.


Frank Sinton thinks human waste is highly underrated -- and highly profitable. A tech entrepreneur and the founder of PMC BioTec, Sinton pounds the table for the benefits of better processing of biowastes as not only environmentally sound but also good business. And he has the technology to prove it. His company and others are on the leading edge of a new generation of companies trying to improve the way society deals with biosolids, also known as sludge.

America spends $5 billion a year dealing with sludge. Biosolids producers pay hundreds of dollars a ton to remove it, quickly filling landfills or other means of disposal, Sinton said on Sept. 15 at the AlwaysOn Going Green Conference in Sausalito, California. The scope of the globe's sludge problem is mindboggling. Every year, cattle feedlots produce more than 150 million tons of animal waste; the U.S. and Europe together generate 40 million tons of sludge from sewage treatment; and food production waste weighs in at a staggering billion tons per year.
Companies working on these types of technologiesBeyond being socially unpalateable, sludge often contains elevated levels of toxic heavy metals such as lead, nickel, and cadmium, which cause serious health problems even at low levels of absorption into groundwater or farm soil. The technology used to extract the metals from sludge lets companies create "organic fertilizer" from biosolids, but environmentalists vehemently oppose such efforts. (When First Lady Michelle Obama planted an organic vegetable garden on the White House lawn, she sparked a political brouhaha when the soil showed detectable levels of lead, attributed to contaminated sludge fertilizer.)

Other, harder-to-destroy substances found in common sludge include the prions believed to cause "mad cow disease," and endocrine-disrupter compounds: complex chemicals that interfere with human hormones. Europe has instituted a ban on putting organic waste in landfills.

That's where Sinton and PMC hope to step in. His $2 million machine is like a giant Port-a-Potty that takes in sludge, mixes it with bacteria, or renders the organic matter into methane gas, an energy source that can offset the high power requirements of many biosolid treatment facilities. Such facilities are among the largest consumers of electricity in many large cities.

Another process, AquaCritox, cooks sludge in a special pressurized vapor chamber at temperatures above 705 degrees Farenheit. The process provides enough heat to produce 2 megawatts of power, using heat-transfer devices and other standard power-generation equipment. The process's byproducts are carbon dioxide, nitrogen and water; heavy metals are collected in a fine ash and can be recycled for industrial use.

While not as sexy as solar-energy power companies like Ausra or electric-vehicle darlings like Tesla Motors, companies looking into waste-energy technologies. But the mandate to deal with sludge in a more ecofriendly and economical fashion may be more potent than the mandate to move to green power. "Thames Water, which produces 25 percent of the biosolids in the U.K., has been instructed to run their operations as energy neutral within 10 years," says John O'Regan, the founder and CEO of SCFI group, the parent company of AquaCritox. "That means they have to look at biosolids as a source of energy."

The ban on biosolids in landfills in Europe adds pressure to figure out what to do with this ugly form of garbage. And in the U.S., as landfills continue to fill up, cities and large corporations are realizing they'll need to figure out alternative means for disposing of their sludge. A key to the adoption process, Sinton and O'Regan believe, will be that the new generation of biosolids treatment technologies can quickly turn into money-saving measures for cash-strapped sewage-plant and feed-lot operators, among others. "Company's have a budget right now," says O'Regan. "It's difficult to get a new technology adopted if you are asking a customer to pay a lot more for it. It's not going to take."

For his part, Sinton's dream is to put a PMC bioreactor in every backyard. "The technology scales down to fit inside a portable toilet," he says. "I'd like to make it so easy and cheap that we can sell them in Home Depot and give everyone a good source of power as well as a better way to get rid of their waste than flushing it down the toilet. That's like washing money right down the pipes."

And just as the technology scales down, it also can scale up. "There is no reason we should not have giant biosolids power plants that can do the same thing as solar power plants and the like," Sinton says. "All the sludge we bury or throw away is wasted energy."

A Green Certification on the Horizon for the White House?

source: greenerbuildings.com

Going far beyond the organic vegetable garden and playground made from recycled materials, President Barack Obama intends to get the White House LEED certified by the U.S. Green Building Council.

That's the word from an article on Sierra Club's Green Home website. From the article:

White House Council on Environmental Quality (CEQ) spokesperson, Christine Glunz, says the effort to get the White House to LEED certification includes energy and water systems as well as waste. She believes it is vital to consider toxicity and life-cycle when making purchases for facilities. CEQ is looking to reduce the carbon footprint of the White House by implementing computerized energy management systems, automatic light sensors that turn off in unoccupied rooms and low-flow water valves. Paints and sealers with low or no volatile organic compounds (VOCs), biodegradable cleaners and recycled equipment will all be used by White House groundskeepers and engineers, according to a White House spokesperson. Window films that will lower UV rays and save energy will also be added.

According to an article on the National Geographic website, any leftover materials from White House renovations and demolitions will be donated to local reuse organizations. If President Obama continues to enforce such eco-friendly changes throughout his term, he will be on the right track to making the White House more of a "green house," proving with a LEED certification that he can lead Americans to a greener world.

LEED is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

Developed by the U.S. Green Building Council (USGBC), LEED provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

LEED is flexible enough to apply to all building types – commercial as well as residential. It works throughout the building lifecycle – design and construction, operations and maintenance, tenant fitout, and significant retrofit. And LEED for Neighborhood Development extends the benefits of LEED beyond the building footprint into the neighborhood it serves.
