, (born May 2, 1947, Cromer, Norfolk, Eng.) British , , and entrepreneur who successfully manufactured innovative household appliances and became a determined campaigner to restore and technical innovation to high esteem in British society.As a boy, Dyson attended the prestigious Gresham’s schools in rural Holt, . After graduation he went to London, where he attended the Byam Shaw School of Art for a year (1965–66) before studying and at the Royal College of Art (1966–70). At the latter institution he was introduced to the creative possibilities of uniting engineering with design. In 1970 he went to work for Rotork Controls Ltd., , Somerset, where he and the company’s unconventional chairman, Jeremy Fry, designed and produced the Sea Truck, a small, fast, versatile flat-bottomed fibreglass for use by military or civilian customers. In 1974 Dyson founded his own company to produce the Ballbarrow, a plastic wheelbarrow-like bin that rolled on a load-spreading ball instead of a narrow wheel.

In 1978 Dyson, having grown impatient with clogged air filters in his Ballbarrow factory, built a similar to devices used in larger industrial plants, such as sawmills. Adapting this solution to home , he worked for the next five years, testing more than 5,000 prototypes, before he produced a satisfactory model that swirled incoming dirty air around a cylindrical container, where the dust was separated by and settled by gravity while the purified air escaped out the top. ge vacuum cleaner beltsMakers of traditional bag-type vacuum cleaners showed no interest in Dyson’s bagless device, arousing in him a lasting antipathy toward conventional businesses. siemens vacuum cleaner partsHe sold the cleaner, known as the G-Force, to a company in Japan, where it became a commercial success and won a design prize in 1991. jual vacuum cleaner murah

In 1993 Dyson opened a plant in , and within two years his Dual Cyclone model became the top-selling in Britain, despite a retail price considerably higher than that of competing brands. Dyson’s elegant and practical appliances went on to win many design awards and were exhibited in art and design museums around the world. He followed up the vacuum cleaner line with other products, such as the Air Multiplier bladeless fan, introduced in 2009, in which air drawn through the base unit is blown over the inner surface of an ethereal airfoil-shaped ring, inducing air surrounding the ring to flow in an uninterrupted stream.Dyson’s design and commercial success lent authority to his quest to revive the spirit of in Britain. In 1997 he published Against the Odds (cowritten with Giles Coren), an autobiographical account of his persistence in the face of discouragement. The following year he was made a Commander of the Order of the British Empire. In 2002 the James Dyson Foundation was established with the aim of encouraging young people to enter engineering through the awarding of prizes and grants.

In 2009 the invited Dyson to propose policies to encourage innovation, and he replied in March 2010 with Ingenious Britain: Making the UK the Leading High Tech Exporter in Europe, a report that suggested, among other ideas, more freedom for universities to design unconventional engineering curricula and more collaboration between universities and companies. invention (musical form)Read Moreindustrial designRead MoreNorth NorfolkRead MoreThey say that nothing ever happens in a vacuum, but this holiday - Create a Vacuum Day, on February 4 - seems to have emerged from one. The source, or even the purpose, of this fun and geeky holiday are unknown, so we can only guess that the holiday calls for people to learn more about the science behind a vacuum and experiment with it (as much as they can with common household equipment). The word, vacuum comes from the Latin word vacuus, meaning empty or vacant, and is used by scientists to refer to a space that does not have any matter or where the pressure is lower than atmospheric pressure.

While theoretically, a perfect vacuum can exist, practically creating one is almost impossible. This is because of, what scientists call virtual particles – particles that can enter and exit a vacuum. Such particles include photons and quarks. Outer space is considered by scientists as being closest to a state of perfect vacuum as there can be, even though it is not completely devoid of matter. Apart from space debris that includes comets and asteroids, outer space has stray atoms of gases and different forms of radiation. In addition to its theoretical applications, the concept of vacuum has led to many industrial and household items that we find indispensable today. In our homes, a vacuum can be used to suck up dirt through the vacuum cleaner and even light up our rooms through incandescent light bulbs. Outside, vacuum is used to pack food and other items, in vacuum pumps, and to build electron microscopes. Even car brakes work by creating a form of vacuum. Learn more about the science behind vacuum, a space completely empty of matter, and its practical uses.

Take out the vacuum cleaner from the closet and use it - you are due to clean your home anyway. …that the world’s first vacuum cleaner was invented in 1866 by Ives W. McGaffey in the United States?It was 21 years ago today that James Dyson launched his iconic cyclonic vacuum cleaner, after laboriously creating 5,127 prototypes. The company is still investing heavily in research and development; Dyson has over 4,000 patent applications for more than 500 inventions. In 2012 it filed more patents than any other business in the UK. Its “pipeline” - the timeline of new products currently under development - is 25 years long. New products are given secret code names for internal use and biometric security protects Dyson’s research and development headquarters in Malmesbury, Wiltshire. To mark the anniversary of the launch of its most iconic product the company has revealed details of three of its inventions which never saw the light of day - until now. And one of them is strikingly similar to Google's Glass wearable computer which was first unveiled in 2012 - more than ten years after Dyson's first sketches.

In 2001 Dyson began work on an augmented-reality headset featuring full colour 3D. It was given the secret code name N066. A device the size of a mobile phone would be carried in the user's pocket, containing the computer, while the slimline headset was worn like a pair of glasses and gave audio prompts and visual cues to overlay information on your view of the real world. It worked by using two mirrors to reflect the images from two tiny monitors that sat near your temples onto a prism in front of your eyes, giving the illusion of a translucent 10in display around one metre in front of you. It showed a series of applications similar to the smartphones of today. A virtual personal assistant, similar to Siri, could read out emails and interpret basic voice commands. As a bonus, the computer module could detach from the glasses and plug into a normal monitor to work like a traditional desktop. James Dyson testing a Halo prototype A control device was worn on the user’s wrist like a watch, mimicking a pointer stick similar to the ones nestled in-between laptop keys.

It allowed the user to move the virtual cursor across the display. It could also be controlled by finger tracking, where you used any flat surface like a touchpad. After three years of research and development the project was put on hold, but the company says that elements of the technology are now being used in future products. The triumph of Google's Glass is that it managed to cram all of those individual components into a single device which is worn like a pair of glasses. Diesel Trap Air pollution contributes to approximately 30,000 deaths a year in Britain. It increases the risk of lung cancer, lung disease, heart attacks, as well as asthma and other respiratory problems. Fine diesel particles are around 2.5 microns in size, and the cyclones on Dyson vacuum cleaners can filter particles down to 0.5 microns; in 1997 Dyson engineers began investigating whether this technology could be applied to diesel engines to clean the fumes they emitted. Initial prototypes focused on cyclones but the required energy consumption was too high.

Condensing oil onto the small particles to increase their radius came next. But the particle size was inconsistent, allowing inaccurate results, so the focus turned to the use of electrostatics and the final system used an electrical discharge to ionise and collect these particles which were then burned off in an oxygen-rich environment. At the time, Dyson had no plans to make a car. All too similar to James Dyson’s battle with the vacuum cleaner bag market, manufacturers were not interested in the technology - instead turning to ceramic filters. Diesel engines now use particulate filters which clog, and as a result drop in performance – the clogging particles are regularly burned off to improve efficiency. The Dyson Fuel Cell Hydrogen fuel cells convert chemical energy from hydrogen and oxygen into electrical energy. Fuel cells require a large, constant source of both hydrogen and oxygen to run, but produce electricity continuously as long as these elements are supplied. For three years, ten Dyson engineers worked to adapt a digital motor so it could sit at the heart of a fuel cell.
