The only place this energy can come from is the moving air. Now, maybe they are trading velocity for volume but the point is that however much energy was put into the air before it is blown out the aerofoil is exactly how much total energy the fan can produce.
yes sir, unless... they have developed one of those free energy developing devices
there could be a market there!
refined induction is what they are talking about, much like a Carburetors fuel jets (plavts soda syphon), replace the fuel with air.
"The breakthrough came when they noticed that accelerating air over a ramp amplified it by 10 – 20 times, drawing in surrounding air through processes known as inducement and entrainment. Hundreds of iterative tests revealed the ideal ramp angle, aperture width and loop amplifier dimensions."
this sentence is quite amusing i thought;
"One engineer had the original idea. But it took every discipline from Dyson’s 350-strong
team of engineers and scientists to develop Air Multiplier™ technology"
i'm guessing the tech might be a wee bit more complex than a cars a/c ducting or that "350-strong team of engineers" must be real silly, how many disciplines are there?
the study of fluid flow obviously isn't a new concept but the tech (the practical application of science to commerce or industry) certainly is wrt to this fan. lost in translation.
