…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”

Nowadays, solar energy is the most important alternative energy source on the planet. Solar centrals will be the main electricity suppliers in the near future. The perfect areas, where these solar centrals would work at maximum capacity are deserts. In deserts the intensity of solar radiation during the day is very high and solar systems would reach maximum efficiency.

One of the most popular deserts, where are planned already several solar projects, is Sahara desert. Europe, Middle East and North Africa could be supplied with electricity produced in Sahara desert. The energy needs could be covered for a period of 40 years, shows a recent study. The most important companies in the world (20 companies) want to invest in the technology needed to produce electricity in Sahara desert. All projects made by these companies will be presented at the end of this year.

Researchers said that solar energy produced in Sahara desert in 6 hours is equal to the energy consumed on the entire planet in a year. These studies have led people to believe that the entire planet could receive electricity from Sahara. This type of project is very difficult to achieve, but with time and advancement in technology, in several years this large project could be a real thing. The costs for such a project are very high, about 400 billion euros, equivalent to building 10 advanced nuclear centrals. In 10 years this large amount of money would be invested and transformed into an inexhaustible energy source.

The electricity consumption on the entire planet is very big today. Researchers estimated that in 2050, world population will be 10 billion people, and to provide energy for their needs it would be necessary to produce energy, three similar planets. For these reasons the 20 companies (Desertec Organization) decided that until 2050 to produce 100GW of solar energy for Europe, Middle East and North Africa. This electricity produced will be transported on high voltage lines to electrical networks from every country.

These solar centrals could create a lot of work places (a 250MW central need services of 1000 workers and engineers in only 2 years). In this way, many countries from Middle East and many poorer countries, could create a new economy, providing jobs and stopping emigration. The risks in building such a big central are very high. The only factor that could damage the central is the sand. This sand could cover the solar system active surfaces and the central efficiency could decrease. For cleaning these surfaces the central need many employees to take care of these problems, and this would involve also a large amount of money. Desertec project includes also producing energy at night by installing a large number of Solar-Thermal centrals. These centrals are different from solar centrals, because are able to store solar heat at night or in cloudy days.

Scientists from the Universities of Exeter and Plymouth are calling for urgent research to understand the impact of renewable energy developments on marine life. The study, now published in the Journal of Applied Ecology, highlights potential environmental benefits and threats resulting from marine renewable energy, such as off-shore wind farms and wave and tidal energy conversion devices.

The research highlights the capacity for marine renewable energy devices to boost local biodiversity and benefit the wider marine environment. Man-made structures on the sea bed attract many marine organisms and sometimes become ‘artifical reefs’, for example, supporting a wide variety of fish. The study also points out that such devices could have negative environmental impacts, resulting from habitat loss, collision risks, noise and electromagnetic fields.

The study highlights the gaps in our understanding of the effects of marine renewable energy devices on the health of our oceans. The team calls for more research to improve our understanding of these threats and opportunities. The researchers also stress the importance of considering the impact on marine life when selecting locations for the installation of marine energy devices.

Corresponding author Dr Brendan Godley of the University of Exeter said: “Marine renewable energy is hugely exciting and it is vital that we explore the potential for it to provide a clean and sustainable energy source. However, to date research into the impact of marine renewable energy on sea life has been very limited. . Our study highlights the urgent need for more research into the impacts of marine renewable energy on marine life. This will involve biologists, engineers and policy-makers working together to ensure we really understand the risks and opportunities for marine life.”

Professor Martin Attrill, Director of the University of Plymouth Marine Institute said: “Our paper highlights the need to take a fresh look at the effect marine renewable energy generation has on the environment if we are to deliver a higher proportion of energy from renewable sources and start to combat climate change. We need to have the industry working directly with conservation bodies to plan the next phase of development. We suggest further research could demonstrate the potential of security zones around, for example, wave farms to act as Marine Protected Areas. Therefore, if all stakeholders can work together in a coordinated way we can possibly address two key issues – combating climate change and creating a network of MPAs. We need the research on environmental impact to help move the whole field forward.”

This study was carried out by PRIMaRE (the Peninsula Research Institute for Marine Renewable Energy), a joint £15 million institute for research into harnessing the energy from the sea bringing together the technology and marine expertise of the Universities of Exeter and Plymouth.

An editorial and letter, published simultaneously by the BMJ and Lancet, warn that failure to agree radical cuts in carbon dioxide emissions at the UN climate change conference in Copenhagen this December spells a global health catastrophe.

The scientific evidence that global temperatures are rising and that man is responsible has been widely accepted since the Intergovernmental Panel on Climate Change’s report in 2007, write Lord Michael Jay and Professor Michael Marmot in the editorial. There is now equally wide consensus that we need to act now to prevent irreversible climate change.

So the chances of success should be good but the politics are tough, they say.

The most vocal arguments are about equity: the rich world caused the problem so why should the poor world pay to put it right? Can the rich world do enough through its own actions and through its financial and technological support for the poor to persuade the poor to join in a global agreement?

These arguments need to be tackled head on, but Jay and Marmot believe that what’s good for the climate is good for health. For example, a low carbon economy will mean less pollution. A low carbon diet (especially eating less meat) and more exercise will mean less cancer, obesity, diabetes, and heart disease. This is an opportunity too to advance health equity, which is increasingly seen as necessary for a healthy and happy society, they say.

They point out that the threat to health is especially evident in poorest countries, particularly in sub-Saharan Africa, where poverty and lack of resources, infrastructure, and often governance, greatly increase their vulnerability to the effects of climate change.

If we take climate change seriously, it will require major changes to the way we live, reducing the gap between carbon rich and carbon poor within and between countries, they write.

A successful outcome at Copenhagen is vital for our future as a species and for our civilisation. Failure to agree radical reductions in emissions spells a global health catastrophe, which is why health professionals must put their case forcefully now and after Copenhagen, they conclude.

In the accompanying letter, doctors leaders across the world call on politicians to heed the health effects of climate change when they meet in Copenhagen.

They warn that “there is a real danger that politicians will be indecisive, especially in such turbulent economic times as these.”

Doctors are still seen as respected and independent, largely trusted by their patients and the societies in which they practise, they write. As such, they urge doctors “to demand that their politicians listen to the clear facts that have been identified in relation to climate change and act now to implement strategies that will benefit health of communities worldwide.”

“Politicians may be scared to push for radical reductions in emissions because some of the necessary changes to the way we live won’t please voters,” said Dr Fiona Godlee, editor in chief of the BMJ. “Doctors are under no such constraint. On the contrary we have a responsibility as health professionals to warn people how bad things are likely to get if we don’t act now. The good news is that we have a positive message – that what is good for the climate is good for health.”

A low carbon diet (especially eating less meat) and more exercise will mean less cancer, obesity, diabetes, and heart disease. This is an opportunity too to advance health equity, which is increasingly seen as necessary for a healthy and happy society, they say.

They point out that the threat to health is especially evident in poorest countries, particularly in sub-Saharan Africa, where poverty and lack of resources, infrastructure, and often governance, greatly increase their vulnerability to the effects of climate change.

If we take climate change seriously, it will require major changes to the way we live, reducing the gap between carbon rich and carbon poor within and between countries, they write.

A successful outcome at Copenhagen is vital for our future as a species and for our civilisation. Failure to agree radical reductions in emissions spells a global health catastrophe, which is why health professionals must put their case forcefully now and after Copenhagen, they conclude.

In the accompanying letter, doctors leaders across the world call on politicians to heed the health effects of climate change when they meet in Copenhagen.

They warn that “there is a real danger that politicians will be indecisive, especially in such turbulent economic times as these.”

Doctors are still seen as respected and independent, largely trusted by their patients and the societies in which they practise, they write. As such, they urge doctors “to demand that their politicians listen to the clear facts that have been identified in relation to climate change and act now to implement strategies that will benefit health of communities worldwide.”

“Politicians may be scared to push for radical reductions in emissions because some of the necessary changes to the way we live won’t please voters,” said Dr Fiona Godlee, editor in chief of the BMJ. “Doctors are under no such constraint. On the contrary we have a responsibility as health professionals to warn people how bad things are likely to get if we don’t act now. The good news is that we have a positive message – that what is good for the climate is good for health.”

For more than a century, a few scientists have occasionally daydreamed of transforming much of the Sahara desert green, with a lush inland sea or vast tracts of farmland. Now researchers say they have actually found a way to make such a scheme work with forests across the desert–and to slow climate change in the process.

The idea is the brainchild of Leonard Ornstein, a cell biologist at the Mount Sinai School of Medicine, who partnered with climate modelers David Rind and Igor Aleinov of NASA’s Goddard Institute for Space Studies, all in New York City. They envision desalinating seawater from the neighboring oceans and bringing it inland using aqueducts and pumps. Drip irrigation–plastic tubing to water the trees’ roots–would minimize the amount of water lost to evaporation and seepage into sandy soils, allowing trees to prosper in areas that are parched today.

According to climate simulations to be published next month in the journal Climatic Change, the forests would cool the Sahara by up to 8°C in some areas. “Eucalyptus grandis and a large number of other tropical tree species are heat-tolerant, so long as they have an ample supply of water in the root zone,” Ornstein says. The tree cover would also bring more rain–about 700 to 1200 millimeters per year–and clouds, which help reflect the sun’s rays back into space. The scheme could also work for the arid Australian outback, the team reports.

Ornstein says that if most of the Sahara and Australian outback were planted with fast-growing trees like eucalyptus, the forests could draw down about 8 billion tons of carbon a year–nearly as much as people emit from burning fossil fuels and forests today. As the forests matured, they could continue taking up this much carbon for decades.

The project wouldn’t be cheap. Adding up the costs for building, running, and maintaining reverse-osmosis plants for desalination and the irrigation equipment, the researchers put the price tag at some $2 trillion per year. The price would be roughly comparable to that of capturing carbon dioxide at power plants and storing it underground, which would eventually cost about $200 per ton of carbon, according to a recent study from Harvard University’s Belfer Center for Science and International Affairs, compared with about $400 per ton of carbon for the forests. “Any solution to climate change has to be a multitrillion-dollar project,” Ornstein says. “The issue is what the payback is.” In several decades, the forests could be sustainably harvested as a source of fuel for wood-burning power plants, making them a nearly carbon-neutral energy source, Ornstein argues.

Planting these forests might have side effects. The increased moisture could trigger plagues of locusts in Africa, just as the odd wet year does now. It could also dampen existing soils, stopping iron-rich dust from blowing off the Sahara and into the Atlantic Ocean, where it nourishes sea life, the study points out.

Despite the drawbacks, the proposal “is incredibly important and definitely worth taking seriously and looking into further,” says atmospheric scientist Richard Anthes, president of the University Corporation for Atmospheric Research in Boulder, Colorado. “The benefits could be enormous and go well beyond carbon sequestration,” making vast areas far more livable and productive. The key issue is whether desalinating enough seawater would be affordable, Anthes adds. “This paper suggests that it is.”

“Salt-loving algae could be the key to the successful development of biofuels as well as being an efficient means of recycling atmospheric carbon dioxide,” Professor John Cushman of the University of Nevada told the Society for General Microbiology meeting at Heriot-Watt University, Edinburgh, Sept. 10.

The current major limitation of biofuel production is the lack of adequate feedstocks, soybeans and corn, for biodiesel and ethanol production, respectively. Halophytic (salt-loving) micro-algae can be grown on marginal lands with brackish or salt water unsuitable for traditional agriculture. Their growth is non-seasonal, making them 10-30 times more productive than terrestrial crops. They can be grown on municipal wastewater and have widespread potential for recycling carbon dioxide from biomass-, coal-, and gas-fired power plants.

Algae are adapted to a wide range of water sources, but grow year-round in warm, tropical or sub-tropical climates. Using geothermal heat, Professor Cushman has been able to extend the growing season for algae production from three months to nine months in colder climates.

“Our work aims to find suitable algal strains to use for biofuel production,” said Professor Cushman. “We need to identify the key components of the biosynthetic pathway to learn how to improve oil production and alter desirable oil characteristics with immediate and significant impact on the emerging algal feedstock biofuels industry.”

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!

The European Union is on the cutting-edge of green technology; already ahead of many nations through its introduction a ban of incandescent light bulbs that began on September 1, 2009. The ban of these incandescent light bulbs has a goal of reducing region-wide energy costs through use of the more eco-friendly compact fluorescent light bulbs instead.

In order to move forward with this ban of incandescent light bulbs, the EU is not allowing retailers in the area to purchase these lighting options which take a known toll on the environment and our household energy costs. With fairness in mind, however, retailers are allowed to continue to sell incandescent light bulbs that they already have in stock. By implementing this ban, the EU is hoping that it will contribute to their goal of reducing greenhouse gasses by 2010 and will convert the population to becoming more energy-efficient in their line of thinking.  THe public has not reacted entirely favorably to this ban, protesting that they have the right to choose their own lighting options in their homes; but meanwhile, the United States is watching closely to see how well received it is since a similar initiative will be underway in 2012.

The ban of incandescent light bulbs in the EU has been motivated by the fact that they are 75% less eco-friendly than compact fluorescent light bulbs, plus CFL’s last 10 times longer so they not only save on energy consumption and cost, but the light bulb very quickly pays for itself through its savings. Little by little, nations worldwide are doing their part to reduce their environmental footprint, and this is one way that the EU is hoping to do their part!
