Bladeless Fan – Blows Air With No Blades!

Excellent design and use of the induction principle.
Induction type Air conditioning system have been used for years in commercial building air conditioning but this is a great adaption and redesign for the domestic use.
Mr Dyson please also adapt for the commercial use using chilled or heated high pressure air to mix with the air in the space. This concept could be used architecturally and is much better than the old induction jets we currently use.
The only not I have is that normally high pressure air is very expansive/high in energy use even when using a turbine type fan as you have. I would like to know how it compares to a normal fan not just an air conditioning system reference.
