…or at least that’s what Ray Kurzweil thinks. He has spent his life inventing machines that help people, from the blind to dyslexics. Now, he believes we’re on the brink of a new age – the ’singularity’ – when mind-boggling technology will allow us to email each other toast, run as fast as Usain Bolt (for 15 minutes) – and even live forever. Is there sense to his science – or is the man who reasons that one day he’ll bring his dad back from the grave just a mad professor peddling a nightmare vision of the future?

Should, by some terrible misfortune, Ray Kurzweil shuffle off his mortal coil tomorrow, the obituaries would record an inventor of rare and visionary talent. In 1976, he created the first machine capable of reading books to the blind, and less than a decade later he built the K250: the first music synthesizer to nigh-on perfectly duplicate the sound of a grand piano. His Kurzweil 3000 educational software, which helps students with learning difficulties such as dyslexia and attention deficit disorder, is likewise typical of an innovator who has made his name by combining restless imagination with technological ingenuity and a commendable sense of social responsibility.

However, these past accomplishments, as impressive as they are, would tell only half the Kurzweil story. The rest of his biography – the essence of his very existence, he would contend – belongs to the future.

Following the publication of his 2005 book, The Singularity is Near: When Humans Transcend Biology, Kurzweil has become known, above all, as a technology speculator whose predictions have polarised opinion – from stone-cold scepticism and splenetic disagreement to dedicated hero worship and admiration. It’s not just that he boldly envisions a tomorrow’s world where, for example, tiny robots will reverse the effects of pollution, artificial intelligence will far outstrip (and supplement) biological human intelligence, and humankind “will be able to live indefinitely without ageing”. No, the real reason Kurzweil has become such a magnet for blogospheric debate, and a tech-celebrity, is that he’s convinced those future predictions – and many more just as stunning – are imminent occurrences. They will all, he steadfastly maintains, happen before the middle of the 21st century.

Which means, regarding the earlier allusion to his mortal coil, that he doesn’t plan to do any shuffling any time soon. Ray Kurzweil, 61, sincerely believes that his own immortality is a realistic proposition… and just as strongly contends that, using a combination of grave-site DNA and future technologies, he will be able to reclaim his father, Fredric Kurzweil (the victim of a fatal heart attack in 1970), from death.

Just when will this ultimate life-affirming feat be possible? In Kurzweil’s estimation, we will be able to upload the human brain to a computer, capturing “a person’s entire personality, memory, skills and history”, by the end of the 2030s; humans and non-biological machines will then merge so effectively that the differences between them will no longer matter; and, after that, human intelligence, transformed for the better, will start to expand outward into the universe, around about 2045. With this last prediction, Kurzweil is referring not to any recognisable type of space travel, but to a kind of space infusion. “Intelligence,” he writes, “will begin to saturate the matter and energy in its midst [and] spread out from its origin on Earth.”

It’s as well to mention at this point that, in 2005, Mikhail Gorbachev personally congratulated Kurzweil for foreseeing the pivotal role of communications technology in the collapse of the Soviet Union, and that Microsoft chairman Bill Gates calls him “the best person I know at predicting the future of artificial intelligence”. A man of lesser accomplishments, touting the same head-spinning claims, would impress few beyond an inner circle of sci-fi obsessives, but Kurzweil – honoured as an inventor by US presidents Lyndon B Johnson and Bill Clinton – has rightfully earned himself a stockpile of credibility.

In person, chewing pensively on a banana, the softly spoken, slightly built Kurzweil looks chipper for his 61 years, and wears an elegantly tailored suit. A father of two, he resides in the Boston suburbs with his psychologist wife, Sonya, but has flown into Los Angeles for a private screening of Transcendent Man, the upcoming documentary that examines his life and theories over a suitably cosmic score by Philip Glass. “People don’t really get their intellectual arms around the changes that are happening,” he says, perched lightly on the edge of a large armchair, his overall sheen of wellbeing perhaps a shade more encouraging than you’d expect from a man of his age. “The issue is not just [that] something amazing is going to happen in 2045,” he says. “There’s something remarkable going on right now.”

To understand exactly what he means, and why he thinks that his predictions bear up to hard scrutiny, it’s necessary to return to the title of the above-mentioned book, and the grand idea on which it’s based: “the singularity”.

Borrowed from black-hole physics, in which the singularity is taken to signify what is unknowable, the term has been applied to technology to suggest that we haven’t really got a clue what’s going to happen once machines are vastly more “intelligent” than humans. The singularity, writes Kurzweil, is “a future period during which the pace of technological change will be so rapid, its impact so deep, that human life will be irreversibly transformed”. He is not unique in his adoption of the idea – the information theorist John von Neumann hinted at it in the 1950s; retired maths professor and sci-fi author Vernor Vinge has been exploring it at length since the early 1980s – but Kurzweil’s version is currently the most popular “singularitarian” text.

“I didn’t come to these ideas because I had certain conclusions and worked backwards,” he explains. “In fact, I didn’t start looking for them at all. I was looking for a way to time my inventions and technology projects as I realised timing was the critical factor to success. And I made this discovery that if you measure certain underlying properties of information technology, it follows exquisitely predictable trajectories.”

For Kurzweil, the crux of the singularity is that the pace of technology is increasing at a super-fast, exponential rate. What’s more, there’s also “exponential growth in the rate ‘ of exponential growth”. It is this understanding that gives him the confidence to believe that technology – through an explosion of progress in genetics, nanotechnology and robotics – will soon surpass the limits of his imagination.

It is also why, in addition to bananas and the odd beneficial glass of red wine, he follows a regime of around 200 vitamin pills daily: not so much a diet as an attempt to “aggressively re-programme” his biochemistry. He claims that tests have shown he aged only two biological years over the course of 16 actual vitamin-popping years. He also says that, thanks to the regime, he has effectively cured himself of Type 2 diabetes. Not even open-heart surgery, which he underwent last year, and from which he made a rapid recovery (“a few hours later I was in the next room, and sent an email”) could dent his convictions. On the contrary, he thinks that the brevity of his convalescence is proof positive that the pills are working. If he slows down the ageing process, he reckons, he’ll be around long enough to witness the arrival of technology that will prolong his life… forever.

Kurzweil was raised in Queens, New York, where two youthful obsessions – electronics and music – would lead to a guest appearance on the 1960s TV quiz show I’ve Got a Secret, on which (aged 17) he showcased his first major invention: a home-made computer that could compose tunes. Five years later came the death (in 1970, when Ray was 22) of his father, Fredric, a struggling composer and conductor who, Kurzweil believes, never really got his due. “I’m painfully aware of the limitations he had, which were not his fault,” he says. “In that generation, information about health was not very available, and we didn’t have [today's] resources for creating music. Now, a kid in a dorm room can create a whole orchestral composition on a synthesizer.”

The tragedy of that loss – and the fact that the means to repair a congenital heart defect were available to him, but not his father – is clearly an intense motivation for Kurzweil. Sometime soon, he believes, he will once again be able to converse with his father, such is the potential of the scientific advances he believes will ultimately pave the way to the singularity. Not everyone, though, concurs with his appraisal of technological progress, and his belief in the imminence of immortality.

Memorably, in the Transcendent Man documentary, Kevin Kelly, founding editor of future-thinking magazine Wired, labels Kurzweil a “deluded dreamer” who is “performing the services of a prophet”. In reacting to that assessment, Kurzweil’s habitually mellow tone of voice takes on a hint – albeit mild – of umbrage. “It’s interesting that [Kelly] says my views are ‘hard-wired’, when I actually think his views are hard-wired,” he says. “He’s a linear thinker, and linear thinking is hard-wired in our brains: it worked very well 1,000 years ago. Some people really are resistant to accepting this exponential perspective, and they’re very smart people. You show them the data, and yes, they follow it, but they just cannot get past it. Other people accept it readily.”

Whereas Kelly differs from Kurzweil on the grounds of interpretation and tone, other voices of dispute are rooted in a deep-seated fear of technological calamity. “The form of opposition from fundamentalist humanists, and fundamentalist naturalists – that we should make no change to nature [or] to human beings – is directly contrary to the nature of human beings, because we are the species that goes beyond our limitations,” counters Kurzweil. “And I think that’s quite a destructive school of thought – you can show that hundreds of thousands of kids went blind in Africa due to the opposition to [genetically engineered] golden rice. The opposition to genetically modified organisms is just a blanket, reflexive opposition to the idea of changing nature. Nature, and the natural human condition, generates tremendous suffering. We have the means to overcome that, and we should deploy it.”

To those opponents who detect a thick strain of techno-evangelism in Kurzweil’s basically optimistic interpretation of the singularity, he reacts with self-parody: there’s a tongue-in-cheek photo in The Singularity is Near of the author wearing a sandwich board bearing the book’s title, and he insists he was never “searching for an alternative to customary faith”. At the same time, he says humankind’s inevitable move towards non-biological intelligence is “an essentially spiritual undertaking”.

Whether or not he attracts a significant following of dedicated believers in search of deliverance, ecstasy or any variation thereof (some commentators have called the singularity “the rapture for geeks”), Kurzweil has undoubtedly positioned himself at the heart of a growing singularity industry. He is a director of the non-profit Singularity Institute for Artificial Intelligence, “the only organisation that exists for the expressed purpose of achieving the potential of smarter-than-human intelligence safer and sooner”; there’s a second film awaiting release (part fiction, part documentary, co-produced by Kurzweil), also based on The Singularity is Near; and in addition to his theoretical books, he has co-authored a series of health titles, including Transcend: Nine Steps to Living Well Forever and Fantastic Voyage: Live Long Enough to Live Forever. The secret of immortality, he wants you to know, is available in book form.

Those who have lent Kurzweil their support include space-travel pioneer Peter Diamandis, chairman of the X-Prize Foundation; videogame designer (and creator of Spore and SimCity) Will Wright; and Nobel Prize-winning astrophysicist George Smoot. All three can be found on the faculty and adviser list of the recently founded Singularity University (Silicon Valley), of which Kurzweil is chancellor and trustee.

If the pace of technology continues to accelerate, as Kurzweil predicts, it seems likely that discussion of the singularity will see an exponential growth of its own. Few would dispute that it’s one of the 21st century’s most compelling ideas, because it connects issues that intensely polarise people (God, the energy crisis, genetic engineering) with sci-fi concepts that stir the imagination (artificial intelligence, immersive virtual reality, molecular engineering). Thanks largely to Kurzweil and the singularity, scenarios once viewed as diverting entertainment are being reappraised with a new seriousness. The line between fanciful thinker and credible, scientific analyst is becoming blurred: what once would have been relegated to the realms of sci-fi is now gaining factual currency.

“People can wax philosophically,” says Kurzweil. “It’s very abstract – whether it’s a good thing to overcome death or not – but when it comes to some new methodology that’s a better treatment for cancer, there’s no controversy. Nobody’s picketing doctors who put computers inside people’s brains for Parkinson’s: it’s not considered controversial.”

Might that change as more people become aware of the singularity and the pace of technological change? “People can argue about it,” says Kurzweil, relaxed as ever within his aura of certainty. “But when it comes down to accepting each step along the way, it’s done really without much debate.”

The greatest thing since sliced bread?

Ray Kurzweil’s guide to incredible future technologies — and when he thinks they’re likely to arrive…

1 Reconnaissance dust

“These so-called ’smart dust’ – tiny devices that are almost invisible but contain sensors, computers and communication capabilities – are already being experimented with. Practical use of these devices is likely within 10 to 15 years”

2 Nano assemblers

“Basically, these are three-dimensional printers that can create a physical object from an information file and inexpensive input materials. So we could email a blouse or a toaster or even the toast. There is already an industry of three-dimensional printers, and the resolution of the devices that can be created is getting finer and finer. The nano assembler would assemble devices from molecules and molecular fragments, and is about 20 years away”

3 Respirocytes

“A respirocyte is a nanobot (a blood cell-sized device) that is designed to replace our biological red blood cells but is 1,000 times more capable. If you replaced a portion of your biological red blood cells with these robotic versions you could do an Olympic sprint for 15 minutes without taking a breath, or sit at the bottom of a swimming pool for four hours. These are about 20 years away” ‘

4 Foglets

“Foglets are a form of nanobots that can reassemble themselves into a wide variety of objects in the real world, essentially bringing the rapid morphing qualities of virtual reality to real reality. Nanobots that can perform useful therapeutic functions in our bodies, essentially keeping us healthy from inside, are only about 20 years away. Foglets are more advanced and are probably 30 to 40 years away”

5 Blue goo

“The concern with full-scale nanotechnology and nanobots is that if they had the capability to replicate in a natural environment (as bacteria and other pathogens do), they could destroy humanity or even all of the biomass. This is called the grey goo concern. When that becomes feasible we will need a nanotechnology immune system. The nanobots that would be protecting us from harmful self-replicating nanobots are called blue goo (blue as in police). This scenario is 20 to 30 years away”

Imagine if you could look at something once and remember it forever. You would never have to ask for directions again. Now a group of scientists has isolated a protein that mega-boosts your ability to remember what you see.

A group of Spanish researchers reported today in Science that they may have stumbled upon a substance that could become the ultimate memory-enhancer. The group was studying a poorly-understood region of the visual cortex. They found that if they boosted production of a protein called RGS-14 (pictured) in that area of the visual cortex in mice, it dramatically affected the animals’ ability to remember objects they had seen.

Mice with the RGS-14 boost could remember objects they had seen for up to two months. Ordinarily the same mice would only be able to remember these objects for about an hour.

The researchers concluded that this region of the visual cortex, known as layer six of region V2, is responsible for creating visual memories. When the region is removed, mice can no longer remember any object they see.

If this protein boosts visual memory in humans, the implications are staggering. In their paper, the researchers say that it could be used as a memory-enhancer – which seems like an understatement. What’s particularly intriguing is the fact that this protein works on visual memory only. So as I mentioned earlier, it would be perfect for mapping. It would also be useful for engineers and architects who need to hold a lot of visual images in their minds at once. And it would also be a great drug for detectives and spies.

Could it also be a way to gain photographic memory? For example, if I look at a page of text will I remember the words perfectly? Or will I simply remember how the page looked?

I can’t see much of a downside for this potential drug, unless the act of not forgetting what you see causes problems or trauma.

Nanosolar has created a thin film solar battery, much more efficient than anything existing on the market nowadays.

Its thin film technology transfers the sun light in a very efficient way. The Nanosolar power plant will begin producing energy in 2008 and will cover 430 megawatts/year. That’s more than all the capacity of the currently installed solar plants in the US. The normal production costs are 3$/watt. Nanosolar’s are 0.3$/watt! And that’s cheaper than coal. Combined with the fact that these solar panels are designed to last for a minimum of 25 years (that’s their guarantee), more and more energy industries will head towards this form of electricity. Their product belongs to the “third wave” of solar technology. Here’s an excerpt from their site about the three solar waves:

“Nanosolar is leading the “Third Wave” of solar power technology:

• The First Wave started with the introduction of silicon-wafer based solar cells over three decades ago. While ground-breaking, it is visible until today that this technology came out of a market environment with little concern for cost, capital efficiency, and the product cost / performance ratio. Despite continued incremental improvements, silicon-wafer cells have a built-in disadvantage of fundamentally high materials cost and poor capital efficiency. Because silicon does not absorb light very strongly, silicon wafer cells have to be very thick. And because wafers are fragile, their intricate handling complicates processing all the way up to the panel product.
• The Second Wave came about a decade ago with the arrival of the first commercial “thin-film” solar cells. This established that new solar cells based on a stack of layers 100 times thinner than silicon wafers can make a solar cell that is just as good. However, the first thin-film approaches were handicapped by two issues:

  1. The cell’s semiconductor was deposited using slow and expensive high-vacuum based processes because it was not known how to employ much simpler and higher-yield printing processes (and how to develop the required semiconductor ink).

  2. The thin films were deposited directly onto glass as a substrate, eliminating the opportunity of

  • using a conductive substrate directly as electrode (and thus avoiding bottom-electrode deposition cost),
  • achieving a low-cost top electrode of high performance,
  • employing the yield and performance advantages of individual cell matching & sorting,
  • employing high-yield continuous roll-to-roll processing, and
  • developing high-power high-current panels with lower balance-of-system cost.
• The Third Wave of solar power consists of companies addressing the above shortcomings and opportunities. Most every of the new companies address one or the other of the above aspects. One company — Nanosolar — brings together the entire conjunction of all seven areas of innovation, each break-through in their own right, to deliver a dramatic improvement in the cost-efficiency, yield, and throughput of the production of much thinner solar cells.”

Let’s just hope this will facilitate the production of solar panels for the new and existing hybrid and electric cars, and we will no longer be dependent of fossil fuel. There are so few solar plants today, that we cannot imagine how big the Sun’s power really is. Let’s hope that in the future, we’ll drive our cars powered by the sun just like the old sailors drove their boats powered by wind. Good work, guys!

Nanosolar has created a thin film solar battery, much more efficient than anything existing on the market nowadays.

Its thin film technology transfers the sun light in a very efficient way. The Nanosolar power plant will begin producing energy in 2008 and will cover 430 megawatts/year. That’s more than all the capacity of the currently installed solar plants in the US. The normal production costs are 3$/watt. Nanosolar’s are 0.3$/watt! And that’s cheaper than coal. Combined with the fact that these solar panels are designed to last for a minimum of 25 years (that’s their guarantee), more and more energy industries will head towards this form of electricity. Their product belongs to the “third wave” of solar technology. Here’s an excerpt from their site about the three solar waves:

“Nanosolar is leading the “Third Wave” of solar power technology:

• The First Wave started with the introduction of silicon-wafer based solar cells over three decades ago. While ground-breaking, it is visible until today that this technology came out of a market environment with little concern for cost, capital efficiency, and the product cost / performance ratio. Despite continued incremental improvements, silicon-wafer cells have a built-in disadvantage of fundamentally high materials cost and poor capital efficiency. Because silicon does not absorb light very strongly, silicon wafer cells have to be very thick. And because wafers are fragile, their intricate handling complicates processing all the way up to the panel product.
• The Second Wave came about a decade ago with the arrival of the first commercial “thin-film” solar cells. This established that new solar cells based on a stack of layers 100 times thinner than silicon wafers can make a solar cell that is just as good. However, the first thin-film approaches were handicapped by two issues:

  1. The cell’s semiconductor was deposited using slow and expensive high-vacuum based processes because it was not known how to employ much simpler and higher-yield printing processes (and how to develop the required semiconductor ink).

  2. The thin films were deposited directly onto glass as a substrate, eliminating the opportunity of

  • using a conductive substrate directly as electrode (and thus avoiding bottom-electrode deposition cost),
  • achieving a low-cost top electrode of high performance,
  • employing the yield and performance advantages of individual cell matching & sorting,
  • employing high-yield continuous roll-to-roll processing, and
  • developing high-power high-current panels with lower balance-of-system cost.
• The Third Wave of solar power consists of companies addressing the above shortcomings and opportunities. Most every of the new companies address one or the other of the above aspects. One company — Nanosolar — brings together the entire conjunction of all seven areas of innovation, each break-through in their own right, to deliver a dramatic improvement in the cost-efficiency, yield, and throughput of the production of much thinner solar cells.”

Let’s just hope this will facilitate the production of solar panels for the new and existing hybrid and electric cars, and we will no longer be dependent of fossil fuel. There are so few solar plants today, that we cannot imagine how big the Sun’s power really is. Let’s hope that in the future, we’ll drive our cars powered by the sun just like the old sailors drove their boats powered by wind. Good work, guys!

Bacteria that generate significant amounts of electricity could be used in microbial fuel cells to provide power in remote environments or to convert waste to electricity. Professor Derek Lovley, from the University of Massachusetts, isolated bacteria with large numbers of tiny projections called pili which were more efficient at transferring electrons to generate power in fuel cells than bacteria with a smooth surface.

The team’s findings were reported at the Society for General Microbiology’s meeting at Heriot-Watt University, Edinburgh, Sept. 7.

The researchers isolated a strain of Geobacter sulfurreducens which they called KN400 that grew prolifically on the graphite anodes of fuel cells. The bacteria formed a thick biofilm on the anode surface, which conducted electricity. The researchers found large quantities of pilin, a protein that makes the tiny fibres that conduct electricity through the sticky biofilm.

“The filaments form microscopic projections called pili that act as microbial nanowires,” said Professor Lovley, “using this bacterial strain in a fuel cell to generate electricity would greatly increase the cell’s power output.”

The pili on the bacteria’s surface seemed to be primarily for electrical conduction rather than to help them to attach to the anode; mutant forms without pili were still able to stay attached.

Microbial fuel cells can be used in monitoring devices in environments where it is difficult to replace batteries if they fail but to be successful they need to have an efficient and long-lasting source of power. Professor Lovley described how G. sulfurreducens strain KN400 might be used in sensors placed on the ocean floor to monitor migration of turtles.

The Lost Orphan Mine below the Grand Canyon hasn’t produced uranium since the 1960s, but radioactive residue still contaminates the area. Cleaning the region takes an expensive process that is only done in extreme cases, but Judy Wall, a biochemistry professor at the University of Missouri College of Agriculture, Food and Natural Resources, is researching the use of sulfate-reducing bacteria to convert toxic radioactive metal to inert substances, a much more economical solution.

The bacteria Wall is studying are bio-corrosives and can change the solubility of heavy metals. They can take uranium and convert it to uraninite, a nearly insoluble substance that will sink to the bottom of a lake or stream. Wall is looking into the bacteria’s water cleansing ability and how long the changed material would remain inert.

Wall’s research could also be beneficial to heavy metal pollution from storage tanks and industrial waste. The bacteria are already present in more than 7,000 heavy metal contaminated sites, but they live in a specific range of oxygen and temperature, making them difficult to control.

“Our research must be done in the absence of air,” Wall said. “Obviously, none but the most committed – and stubborn – will work with them.”

Even if an oxygen-tolerant strain were developed, there are still multiple factors that would make applying the bacteria challenging, and these microbes can contribute to massive iron corrosion.

“Knowledge of the way bacteria live in the environment, in microbial communities, is still in its infancy,” Wall said. “We just don’t know a lot about the communication systems among microbes.”

Wall and researchers from the Lawrence Berkley National Laboratory in California are investigating the bacterium’s basic genetics and hope to determine its growth limits and activity in natural settings, including how to make its interactions with metals sustainable. They have already identified a few genes that are critical to converting uranium.

Wall’s research has been published in Applied and Environmental Microbiology, Nucleic Acids Research and Environmental Microbiology.

Kevin Warwick’s new robot behaves like a child. “Sometimes it does what you want it to, and sometimes it doesn’t,” he says. And while it may seem strange for a professor of cybernetics to be concerning himself with such an unreliable machine, Warwick’s creation has something that even today’s most sophisticated robots lack: a living brain.

Life for Warwick’s robot began when his team at the University of Reading spread rat neurons onto an array of electrodes. After about 20 minutes, the neurons began to form connections with one another. “It’s an innate response of the neurons,” says Warwick, “they try to link up and start communicating.”

For the next week the team fed the developing brain a liquid containing nutrients and minerals. And once the neurons established a network sufficiently capable of responding to electrical inputs from the electrode array, they connected the newly formed brain to a simple robot body consisting of two wheels and a sonar sensor.

A relay of signals between the sensor, motors, and brain dictate the robot’s behavior. When it approaches an object, the number of electrical pulses sent from the sonar device to the brain increases. This heightened electrical stimulation causes certain neurons in the robot’s brain to fire. When the electrodes on which the firing neurons rest detect this activity, they signal the robot’s wheels to change direction. The end result is a robot that can avoid obstacles in its path.

At first, the young robot spent a lot of time crashing into things. But after a few weeks of practice, its performance began to improve as the connections between the active neurons in its brain strengthened. “This is a specific type of learning, called Hebbian learning,” says Warwick, “where, by doing something habitually, you get better at doing it.”

The robot now gets around well enough. “But it has a biological brain, and not a computer,” says Warwick, and so it must navigate based solely on the very limited amount of information it receives from a single sensory device. If the number of sensory devices connected to its brain increases, it will gain a better understanding of its surroundings. “I have another student now who has started to work on an audio input, so in some way we can start communicating with it,” he says.

But it would be a bit shortsighted to say that adding sensory input devices to the robot would make it more human, as theoretically there is no limit to how many sensory devices a robot equipped with a biological brain could have. “We are looking to increase the range of sensory input potentially with infrared and other signals,” says Warwick.

A robot that experiences its environment through devices like sonar detectors and infrared sensors would perceive the world quite differently from a person. Imagine having a Geiger counter plugged into your brain?—?or perhaps better yet, an X-ray detector. For future generations of Warwick’s robot, this isn’t just a thought experiment.

But Warwick isn’t interested only in building a robot with a wide range of sensory inputs. “It’s fun just looking at it as a robot life form, but I think it may also contribute to a better understanding of how our brain works,” he says.

Warwick’s robot is dependent upon biological cells, so it won’t live forever. After a few months, the neurons in its brain will grow sluggish and less responsive as learning becomes more difficult and the robot’s mortal coil begins to take hold. A sad thought perhaps?—?but such is life.

Kevin Warwick’s new robot behaves like a child. “Sometimes it does what you want it to, and sometimes it doesn’t,” he says. And while it may seem strange for a professor of cybernetics to be concerning himself with such an unreliable machine, Warwick’s creation has something that even today’s most sophisticated robots lack: a living brain.

Life for Warwick’s robot began when his team at the University of Reading spread rat neurons onto an array of electrodes. After about 20 minutes, the neurons began to form connections with one another. “It’s an innate response of the neurons,” says Warwick, “they try to link up and start communicating.”

For the next week the team fed the developing brain a liquid containing nutrients and minerals. And once the neurons established a network sufficiently capable of responding to electrical inputs from the electrode array, they connected the newly formed brain to a simple robot body consisting of two wheels and a sonar sensor.

A relay of signals between the sensor, motors, and brain dictate the robot’s behavior. When it approaches an object, the number of electrical pulses sent from the sonar device to the brain increases. This heightened electrical stimulation causes certain neurons in the robot’s brain to fire. When the electrodes on which the firing neurons rest detect this activity, they signal the robot’s wheels to change direction. The end result is a robot that can avoid obstacles in its path.

At first, the young robot spent a lot of time crashing into things. But after a few weeks of practice, its performance began to improve as the connections between the active neurons in its brain strengthened. “This is a specific type of learning, called Hebbian learning,” says Warwick, “where, by doing something habitually, you get better at doing it.”

The robot now gets around well enough. “But it has a biological brain, and not a computer,” says Warwick, and so it must navigate based solely on the very limited amount of information it receives from a single sensory device. If the number of sensory devices connected to its brain increases, it will gain a better understanding of its surroundings. “I have another student now who has started to work on an audio input, so in some way we can start communicating with it,” he says.

But it would be a bit shortsighted to say that adding sensory input devices to the robot would make it more human, as theoretically there is no limit to how many sensory devices a robot equipped with a biological brain could have. “We are looking to increase the range of sensory input potentially with infrared and other signals,” says Warwick.

A robot that experiences its environment through devices like sonar detectors and infrared sensors would perceive the world quite differently from a person. Imagine having a Geiger counter plugged into your brain?—?or perhaps better yet, an X-ray detector. For future generations of Warwick’s robot, this isn’t just a thought experiment.

But Warwick isn’t interested only in building a robot with a wide range of sensory inputs. “It’s fun just looking at it as a robot life form, but I think it may also contribute to a better understanding of how our brain works,” he says. Studying the ways in which his robot learns and stores memories in its brain may provide new insights into neurological disorders like Alzheimer’s disease.

A driverless taxi has been unveiled which could make traffic jams, petrol fumes and crowded buses a thing of the past.

The futuristic pod has no driver, and no opinionated chatter to accompany your journey, but instead a button set in the wall with the word ’start’ written beside it.

The British-designed personal rapid transport (PRT) system is a four-passenger vehicle which is being rolled out next year at Heathrow Terminal 5

A visitor tries out the driverless pod at the Science Museum, where it is on display before becoming part of the Heathrow fleet next year

Professor Martin Lowson, the inventor, seated inside

The four-seater cab was unveiled at the Science Museum in London yesterday and will be in use from next year taking passengers between car parks and Terminal 5.

The man behind the mission, Professor Martin Lowson, who has a background in space travel and worked on the Saturn V Rocket, said: ‘They could have the same effect on transport this century as the rocket had on the 19th.’

He added: ‘We believe that our PRT system can transform cities in the 21st century to provide the optimum form of environmentally friendly urban transport, relieving congestion and reducing emissions.’

The bubble-shaped taxis are battery-powered and passengers select their destination from a touch screen.

They can reach speeds of up to 25mph and would travel along their own narrow road system.

Once the destination has been chosen, the control system logs the request and sends a message to the vehicle, which then follows an electronic pathway.

During the journey, a passenger can press a button to speak to the controller if necessary.

Prof Lowson has been working on the taxis with Bristol-based Advanced Transport Systems since 1995.

Inside the taxi – the futuristic controls (left), and windows, which appear clear from the inside

A test run of how the cabs could work takes place in Birmingham

At Heathrow, 18 vehicles have been bought to transport passengers and their luggage from the Terminal 5 Business Car Park to the terminal, which will take between three and four minutes.

About 500,000 passengers are expected to use the Heathrow PRT system each year.

Bath and Daventry councils are considering ordering the cabs, and ATS has already received enquiries from America, the Middle East and India.

Drawing inspiration from science fiction? The Logan’s Run car was a driverless pod

A driverless taxi has been unveiled which could make traffic jams, petrol fumes and crowded buses a thing of the past.

The futuristic pod has no driver, and no opinionated chatter to accompany your journey, but instead a button set in the wall with the word ’start’ written beside it.

The British-designed personal rapid transport (PRT) system is a four-passenger vehicle which is being rolled out next year at Heathrow Terminal 5

A visitor tries out the driverless pod at the Science Museum, where it is on display before becoming part of the Heathrow fleet next year

Professor Martin Lowson, the inventor, seated inside

The four-seater cab was unveiled at the Science Museum in London yesterday and will be in use from next year taking passengers between car parks and Terminal 5.

The man behind the mission, Professor Martin Lowson, who has a background in space travel and worked on the Saturn V Rocket, said: ‘They could have the same effect on transport this century as the rocket had on the 19th.’

He added: ‘We believe that our PRT system can transform cities in the 21st century to provide the optimum form of environmentally friendly urban transport, relieving congestion and reducing emissions.’

The bubble-shaped taxis are battery-powered and passengers select their destination from a touch screen.

They can reach speeds of up to 25mph and would travel along their own narrow road system.

Once the destination has been chosen, the control system logs the request and sends a message to the vehicle, which then follows an electronic pathway.

During the journey, a passenger can press a button to speak to the controller if necessary.

Prof Lowson has been working on the taxis with Bristol-based Advanced Transport Systems since 1995.

Inside the taxi – the futuristic controls (left), and windows, which appear clear from the inside

Easy rider: A passenger tries out the driverless cab

A test run of how the cabs could work takes place in Birmingham

At Heathrow, 18 vehicles have been bought to transport passengers and their luggage from the Terminal 5 Business Car Park to the terminal, which will take between three and four minutes.

About 500,000 passengers are expected to use the Heathrow PRT system each year.

Bath and Daventry councils are considering ordering the cabs, and ATS has already received enquiries from America, the Middle East and India.

Drawing inspiration from science fiction? The Logan’s Run car was a driverless pod

How much carbon dioxide do computers emit?

AVIATION has long been blamed for its share of anthropogenic global warming. Indeed, some travellers now ask themselves whether their flight is strictly necessary and, if they decide it is, salve their consciences by paying for the planting of trees. These, so they hope, will absorb the equivalent of their sinful emissions. But you, dear reader, are indulging right now in activity that is equally as polluting as air travel: using a computer.

According to a report published by the Climate Group, a think-tank based in London, computers, printers, mobile phones and the widgets that accompany them account for the emission of 830m tonnes of carbon dioxide around the world in 2007. That is about 2% of the estimated total of emissions from human activity. And that is the same as the aviation industry’s contribution. According to the report, about a quarter of the emissions in question are generated by the manufacture of computers and so forth. The rest come from their use.

EPADown on the server farm

The same report estimates that the spread of computers will increase these associated emissions by about 6% a year until 2020, when one person in three will own a personal computer, half will have a mobile phone and one household in 20 will have a broadband internet connection. Yet computing can also be used to tackle climate change. For example, domestic consumption could be cut by the large-scale employment of smart meters in houses and flats. Households are the biggest users of electricity after manufacturing and transport. In Britain, they accounted for 29% of consumption in 2004, according to a government report.

Small and medium-sized businesses, meanwhile, could save electricity by switching to distributed computing, rather than running their own servers. The delivery of computer services over the internet, from vast warehouses of shared machines, enables firms to hand over the running of their e-mail, customer databases and accounting systems to someone else. Companies that do so use computers more efficiently and thus reduce not only their costs but also their carbon footprints.

Another way to improve the situation is virtualisation—the creation of “virtual” machines (ie, software emulations of separate computers) so that multiple operating systems and applications can run on the same piece of physical kit. Sun Microsystems, a maker of servers, reckons that 70% of the servers in most organisations have only one application running on them. Consolidating these applications onto fewer and fewer machines, courtesy of virtualisation, would be more efficient and thus greener.

Ironically, of course, environmental research itself relies heavily on computers. So, perhaps the best thing the home user can do is donate his inefficiencies to the cause by signing up to climateprediction.net, which uses the idle capacity of home computers to test the accuracy of various computer models of the climate.
