We have "special" fans for sale over here, ones with foam blades to avoid chopping off the kiddo's fingers. Other than making a lot of noise, they don't really move any air at all.From the movie in one of those links it seemed pretty quiet.
And it might be great for use in AC rather than using ion field or whatever it is they do, for quiet airflow..
But as a fan, if it doesn't oscillate and change angle like a 10 dollar bladed fan does it's not really worth the added child safety of it not cutting off your child's fingers.
Kids have tiny fingers
Looks pretty cool but I really wonder what kind of sound it's going to make compared to a normal fan
Also, just curious about something: when he says, "...and we haven't got air conditioning...", he is just making an example, right? Just the way he phrases it makes it sounds like A/C is outlawed in Britain or something.
