Dyson have produced an electric fan which they claim is the first in the world that works without blades.
The Dyson Air Multiplier® fan contains a small motor at the base of a large plastic loop. This creates a flow of air over the curved surface, which brings in more air to create a draught, much the same way as air flows over an aircraft wing. Dyson say that 15 times more air is blown out than is performed by its motor. Here is the main drawing from the patent specification, which was published in March.
October may seem an odd time to launch a cooling product, but the company point out that it is the perfect time to launch in Australia. The UK retail price will be about £199 -- high, perhaps, but Dyson believe that people will pay for quality. CNET has an article about it.
[This patent application looks being being granted soon in Europe -- the European Patent Office states in its official status register that grant is intended, see the relevant webpage. Ed. -- 27 Jan 2010].
Wow! what a technology, I never heard these kind of fans actually, I am surprised to hear this news. well, what will be the cost of this fan? is it more pricey than normal fans? I am excited to know. thanks Dyson to provide a hi-tech facility. I am waiting for it. [They are priced at about £200 in the UK -- ed,]
