Nanotechnology
The above term coined by Dr Eric Drexler in his book Engines of Creation (1986) was intended to be a new science which would astound the world, having the same effect as the industrial revolution and nuclear power had on us. The word nanotechnology may be a new word to you now, but within a decade or two it could be one of the most important words to know.The word is derived from the Greek word for midget, nano, and teks (technology), meaning to fabricate, or create. In metric terminology nano is a prefix, which refers to a billionth of, and in this case that is a billionth of a meter, a nanometer (10-9).Nanotechnology, often called molecular technology, will simply allow us to arrange individual atoms, in all the different ways permitted by the laws of physics. We will build products up from the individual atoms, perfectly, and precisely placing each atom as we desire. How we arrange theses atoms will ultimately determine what we make. If we re-arrange the atoms in coal, we can get a diamond. Technology, as evolution has shown, progresses along a constant, but often-bumpy road. There are really only two variables on this road, and that is size versus power. You often have to sacrifice size fo
All of the above are not true to the sense of what this revolutionary technology should be. Nanotechnology could spell disaster for the world, if not controlled and regulated. We could clean the beaches, seas and skies of all the dirt we have put into them over the last 1000 years. C's billions of times faster than current ones· The ability to cure currently incurable diseases· The ability to stop pollution and to be able to clean pollution from our past· To prevent all famine around the world· Reintroduction of extinct plants and animals· And cheap, affordable space travel. SizeTo help you grasp the concept of how small a nanometer is, understand this. Scientists also recommend that all developments should be made public, so as to allow every one to be involved, and to try and prevent from groups going underground, with private, possibly dangerous research. · Samsung's latest washing machine use nano-sized silver particles, which help as a detergent and prevent odours. They are being used in tennis rackets, and are extremely strong and light. · Clothes manufacturers, such as GAP, Levis and Dockers, apply a stain resistant layer of nanofibres onto their clothes. And tools such as the molecular tweezers have been created. For example a self-replicating system could recreate itself many times, this would help to reduce manufacturing cost, and time, as it would increase exponentially, as more machines are created. Even though you will be hearing and seeing a lot of 'nanotechnology' in the market place, it is not really nanotechnology, in the true sense. It is an excellent source of energy for the planet, producing far less pollution than coal, and gives more power. Future computers are expected to be a million, or even a billion times faster that our current computers.
