There is gong to be a few embarrassing visits to hospital.
(From ThePoke)
Like most high profile "engineers" (as opposed to real ones) Dyson just takes existing inventions, tarts them up, manufactures them in China and markets the fk out of them. Meanwhile giving the impression that he is some sort of inventing genius and an amazing engineer.
His "digital" motor is just a switched reluctance brushless motor. Nothing new there again except refinements to get the speed up, size down and again air path design and packaging.
The fans use the same motors and pass air through a slim vent to cash in on some standard fluid mechanics effects. Its not new or revolutionary stuff, but someone had to make the connections and put it all together. Its still a nice piece of engineering.
From where I sit I can't see anything that they make that is truly an engineering revolution but then a lot of successful engineering has come about by people simply taking what is already out there and using it in a different application and integrating systems.
Riversimple are doing much the same with their new electric vehicle; 8kW fuel cell + a bank of super caps to handle transience. Hub motors to give a completely flat floor etc etc. They are not in the business of inventing a ground breaking new tech. They are taking existing stuff and integrating it intelligently. Dyson are no different in my opinion, doesn't make him a genius but doesn't make him out as a con man either.
