This is so cool... we have to share it here.
Imagine.. a fan without fan-blade..
just a big hole there,
yet you have continuous un-interrupted wind
This is the technology bought to us by Dyson(r).
(not long ago they also bringing in the special hand dryer that can save electric with their 'air blade' technology)
Actually the fan DO have fan-blade, but it is hidden below it,
The wind come out around the 'ring' on top,
and with basic physic of "inducement" and "entrain"
more air is drawn and move to same direction,
thus we have strong air from the tiny fan blade hidden below. :)
