eductors - they do move a greater volume of air than the fan that's hidden in the base does by itself.I'm not really sure what the advantages of the Dyson fans are, other than looking sort of cool and not providing an obvious enticement to small children for the insertion of body parts, objects, liquids, or other substances.
Yep, that’s kind of like ignoring the turbojet art of a jet engine and saying that the tail one nozzle generates all the thrust with no moving parts.“A unique propulsion system that uses turbo-compressors ...with no moving parts”.
Yup, that will be a unique turbo-compressor.
This still works on people for some reason. It's like saying electric cars are zero emissions, nuclear energy is zero emissions or renewable, etc. I could argue that powering my home on 'D' cells from WalMart is zero emissions.“A unique propulsion system that uses turbo-compressors ...with no moving parts”. Yup, that will be a unique turbo-compressor.
Wouldn't claim different, duct losses would likely be massive - but I'm pretty sure that calculation is above my paygradeSure, but energy is lost in the process.
