Britain's Sir James Dyson known for creating the first bagless vacuum cleaner, just to launch a curious circular fan which apparently works without blades. Dyson spent four years developing and perfecting the technology Air. Fluctuations in air were mapped with laser Doppler anemometry, helping to take measures to control the flow of air machine. The secret of the new Air Multiplier hidden in the handle, where a device rotates and pushes up the air, traveling through the ring rises to 15 times volume and spreads in all directions. Although Dyson admitted that his invention does not move as much air as a conventional fan, says, "is of higher quality" because it creates a steady stream without the nagging feeling that the blades "cut" the air. In addition, the gadget is especially interesting in households with children tempted to put your fingers between the blades during operation.
