Who invented the ballbarrow and the `Airblade' hand-drier amongst many other things?
Ballbarrow Later the design was changed to a plastic hopper, with an optional clip on height-extension piece. The Ballbarrow won the Building Design Innovation Award in 1977. Dyson continued with the ball-wheel concept in his design for the Trolleyball boat launcher in 1978, and the DC15 vacuum cleaner in 2005. Ballbarrow The Ballbarrow was a variation of the wheelbarrow design, by James Dyson and was released in 1974 in the UK. It featured a moulded plastic hopper on a steel frame and a spherical plastic wheel, allowing increased manoeuvrability. Dyson said that the surface area of the ball, larger than that
Dyson Airblade conventional hand dryers. The first commercially available high-speed, horizontal-wiping air dryer was the Mitsubishi Jet Towel, invented in 1993 and available in the United States since 2005. There are several technical differences among electric hand dryers, such as airspeed, water containment, energy efficiency, use of heat, type of filter, motor lifespan and power usage. The same technology is used by Dyson in the Air Multiplier fan to create a cooling air stream for personal comfort. The Dyson Airblade is 69% more energy-efficient than conventional hand-dryers and 97% more cost effective than paper towels. The Airblade is cheaper to operate because
