Can El Reg do their research properly
The way air is "multiplied" here is NOT Dyson innovation, it is a Remington one. Its first appearance in a consumer product was in the Remington Vortex hair drier about 12 years ago. Dyson may have changed the design slightly to make it into a shiny Dyson toy, but that is about it. That is besides the fact that similar principles have been used in turbines for 40+ years.
Innovations some other time. More like misleading marketing about being innovative. It is not the first time either. There are other examples - the Airblade (same design shipped by Mitsubishi for years) and so on.
