Immortality only 20 years away says scientist
Scientist Ray Kurzweil claims humans could become immortal in as little as 20 years' time through nanotechnology and an increased understanding of how the body works.

Ray Kurzweil claims we could all be cyborgs in 20 years.

The 61-year-old American, who has predicted new technologies arriving before, says our understanding of genes and computer technology is accelerating at an incredible rate.

He says theoretically, at the rate our understanding is increasing, nanotechnologies capable of replacing many of our vital organs could be available in 20 years time.

Mr Kurzweil adds that although his claims may seem far-fetched, artificial pancreases and neural implants are already available.

Mr Kurzweil calls his theory the Law of Accelerating Returns. Writing in The Sun, Mr Kurzweil said: "I and many other scientists now believe that in around 20 years we will have the means to reprogramme our bodies' stone-age software so we can halt, then reverse, ageing. Then nanotechnology will let us live for ever.

"Ultimately, nanobots will replace blood cells and do their work thousands of times more effectively.

"Within 25 years we will be able to do an Olympic sprint for 15 minutes without taking a breath, or go scuba-diving for four hours without oxygen.

"Heart-attack victims – who haven't taken advantage of widely available bionic hearts – will calmly drive to the doctors for a minor operation as their blood bots keep them alive.

"Nanotechnology will extend our mental capacities to such an extent we will be able to write books within minutes.

"If we want to go into virtual-reality mode, nanobots will shut down brain signals and take us wherever we want to go. Virtual sex will become commonplace. And in our daily lives, hologram like figures will pop in our brain to explain what is happening.

"So we can look forward to a world where humans become cyborgs, with artificial limbs and organs."

Going Down The Rabbit Hole

Going Down The Rabbit Hole
GOOD
April 7, 2009

The future of transportation may mean not moving at all.

Ray Kurzweil, an inventor and technology theorist, envisions a future in which advances in nanotechnology, genetics, and robotics give us immortality; clean, free energy; and a completely new definition of mobility. Think plug-in electric cars and maglev trains are the transportation innovations of tomorrow? Kurzweil is looking quite a bit further down the road.

GOOD: How will technological advances change transportation in the 21st century?

Ray Kurzweil: For starters, we will replace a lot of transportation with the ability to meet each other in virtual reality. I give about a third of my speeches around the world using a virtual-communication system that allows me to appear at a venue in three dimensions and in real time. My image is three-dimensional, life-sized, and fully realistic. As I move around, the audience sees their local background behind me.

Ultimately, virtual reality will be extremely realistic and incorporate all of the senses. If we go out to around 2030, we will be able to send someone an information file (as an email attachment, for example) and they will “print” it out in three dimensions to create virtually any three-dimensional object, such as a computer, a solar panel, a module to build housing, food, or clothing. This will replace most of the transportation needed to ship products.

G: So we’ll have realistic virtual reality and the ability to print three-dimensional products at home. Will travel be altogether obsolete in the future? What’s the time line for this happening?

RK: During the teen years of this century we will use high-resolution image beamers in our glasses to beam images directly to our retinas to create full-immersion visual virtual-reality environments, and use comparable devices for the audio component. Since most business interactions are visual and auditory, this will meet most business needs for meetings.

By the late 2020s, nanobots in our brain (that will get there noninvasively, through the capillaries) will create full-immersion virtual-reality environments from within the nervous system. So if you want to go into virtual reality the nanobots shut down the signals coming from your real senses and replace them with the signals that your brain would be receiving if you were actually in the virtual environment. So this will provide full-immersion virtual reality incorporating all of the senses. You will have a body in these virtual-reality environments that you can control just like your real body, but it does not need to be the same body that you have in real reality. We’ll be able to interact with people in any way in these virtual-reality environments. That will replace most travel, but we’ll also have new travel technologies for our real bodies using nanotechnology.

G: Wow. Well, in the near term, President Obama is talking about converting the federal fleet to hybrid cars and spending $8 billion on high-speed rail. Given the radical changes you envision, does this focus on hybrid cars and high-speed trains seem shortsighted to you?

RK: It’s not shortsighted. These are constructive steps and bring us closer to a world of clean energy. Twenty years from now we will be able to get all of the energy we need from very inexpensive nanoengineered solar panels and store the energy in small, decentralized nanoengineered fuel cells. Solar power is, in fact, doubling every two years and has been for 20 years, and we are only eight doublings away from it meeting 100 percent of the world’s energy needs. And we have 10,000 times more sunlight than we need to do this. But we cannot simply implement a circa-2029 infrastructure today. We should use today’s technology aggressively to meet challenges such as clean energy.

“By the late 2020s, nanobots in our brain will create full-immersion virtual-reality environments from within the nervous system. That will replace most travel.”

G: As you say, we’re stuck with 2009 infrastructure for now, and it’s built for the automobile. What do you see as the future of the car?

RK: Our personal vehicle will depend on the era. Within a decade, cars will communicate with each other, avoiding accidents. Some navigation systems are already taking current traffic patterns into account. That will be ubiquitous quite soon. In the 2030s, we will have personal flying vehicles that use nanoengineered microwings.

G: What do you see as the future of travel in space?

RK: We will continue to explore space as an engineering challenge and as a way of exploring our part of the universe. But space travel will be of strategic importance to our human-machine civilization in the 22nd century. At that point, we will have exhausted the resources on Earth and will move out into the rest of the universe. For the most part, we won’t be sending out missions of squishy creatures but rather swarms of nanobots.

G: What future transportation challenges are we failing to anticipate right now?

RK: Right now, transportation is a major contributor to the negative environmental effects of energy usage (and I believe we should be looking at the full range of these environmental issues and not just greenhouse gases). But as I said, we will be less reliant on transportation as virtual reality becomes more realistic.

the 'grey goo' in nanotechnology Frankenfoods

Alert over the march of the 'grey goo' in nanotechnology Frankenfoods
By SEAN POULTER
2nd January 2008

Some skin creams use nano particles but many are now concerned about the use of the technology in foods

A breed of Frankenfood is being introduced into human diet and cosmetics with potentially disastrous consequences, experts said last night.

Academics, consumer groups and Government officials are warning that the arrival of nanotechnology threatens dangerous changes to the body and the environment.

The particles it uses are so small - 80,000 times thinner than a human hair - that they can pass through membranes protecting the brain or babies in the womb.

Nano health supplements, such as antioxidants, are already on the market while the first of hundreds of new foods are expected to arrive in the next 12 months.

However, the products are being introdeduced without any regulation or independent assessment to ensure they are safe - mirroring the controversy over the launch of GM foods ten years ago.

Some critics have talked of the threat of the creation of a "grey goo" of tiny particles with hidden harmful properties.

Prince Charles has said it would be "surprising" if the technology did not "offer similar upsets" to thalidomide - the morning sickness drug that caused children to be born with deformed limbs.

Professor Vicki Stone, Professor of Toxicology at Napier University in Edinburgh, is concerned about unforeseen side effects.

"We know very little about the ability of nanoparticles to move around the body, to accumulate or to be excreted, or their potential to cause toxic effects in organs," she said.

However, nanotech advocates have remarkable claims for the technology. For example, foods are in development that are said to stave off the aging process.

On a more trivial level, they suggest it would be possible to create a fizzy drink that changes flavour according to the number of times the can is shaken.

The consumer group Which? is about to launch a nanotech campaign arguing that consumers need to be consulted on the risks and benefits before it is too late.

The food and farming department Defra has published an independent report which admits there are serious gaps in safety data.

It warns: "There could be very significant implications for business and the wider community if potential risks are not identified and managed before any harm to the environment or human health may be done."

The report - Characterising the Risks Posed by Engineered Nanoparticles - states there is a shortage of research money.

It says the resulting absence of basic information about the particles means "it will be difficult or impossible to develop any general understanding of nanoparticle toxicology".

The report adds: "Transfer across biological barriers - e.g. to the brain or foetus - should be studied. Research into how long these tiny particles persist in the body is urgently needed."

It warns that work assessing human toxicology is being hamstrung by "profound difficulties in accessing relevant funding for these longer term projects".

Research by Which? found six out of ten people (61 per cent) have never heard of nanotechnology.

Sue Davies of Which? said: "The benefits that nanotechnologies can offer consumers are really exciting.

'But before the market is flooded with products, it's crucial the Government addresses the lack of scientific understanding about how some nanoparticles behave."

The European Food Safety Authority last year held a conference on the future of food.

Dr Donald Bruce, an expert on food and ethics, told delegates that the arrival of nanotech foods has many similarities with GM products.

US corporations attempted to introduce GM before an effective safety regime could be established.

"One of the things to ask is do we need the benefits claimed by the producers?' he said. 'Also there is the underlying notion that we are tampering with nature."

Environment minister Phil Woolas admitted there were gaps in knowledge, but denied the Government was failing to provide enough research cash.

Tiny particles that have generated great hopes and growing concerns

Nanotechnology involves using a substance in particles that are so small that the substance takes on new properties.

The name of the technology comes from the size of the particles - one nanometre in diameter - a millionth of a millimetre. Reduced to this size, materials can suddenly show very different and unexpected properties.

For example, an opaque substance such as copper becomes transparent, or an inert metal such as platinum becomes a catalyst and triggers chemical reactions.

Advocates argue that such particles can be organised to work together to deliver specific effects in a piece of equipment or in the human body.

They can be used to build miniature hard drives that have an immense memory, so allowing further miniaturisation and sophistication of products such as computers and mobile phones.

Washing machines have been developed that release silver nanoparticles that will kill bacteria in dirty washing.

Sun creams have been created so they become transparent rather than chalky white.

In medicine, it is claimed that nanotechnology will allow the creation of drugs that reach and treat a problem quickly.

Manufacturers are working on nanotech foods and supplements that are also designed to deliver specific health benefits.

Similarly, firms are working on developing anti-ageing foods, where nanotech particles associated with renewing the skin from the inside could be included in everyday products such as yoghurt, spreads or breakfast cereals.

The technology promises huge riches for firms which develop winning applications.

One of the first group of nanoparticles being utilised are fullerenes - tiny hollow carbon balls and tubes. They are very heat resistant, strong and conduct electricity.

The football-shaped C60 fullerene is being used in some anti-ageing products. The creams are said to reduce fine lines and firm the skin.

C60 has some antioxidant properties in that it kills the rogue chemicals which damage cells. However, a high dose can itself damage cells.

Some nano particles are known to mimic the harmful effects of asbestos on the lungs. Consequently, they have the potential to trigger lung cancer if inhaled.
