Abstract: A blower/fan for the purpose of greatly reducing noise levels and extending longevity over conventional blade-based blower/fans (e.g., 50 decibel leaf-blower), due to having a totally novel absence of moving parts, such as motor and blades, which create most of the noise and wear out faster. The air motivating force comes from an electrohydrodynamic ionic wind created by a very strong electric field crossing two uniquely configured electrodes. This wind is then further amplified by inducing outside air to be added to this wind by means of a Coand? surface at the entrance to the wind tunnel and which then feeds over a slit. A diffuser section follows causing the wind pressure to build for improving the exiting air characteristics. The novel diffuser and Coand? surfaces will have reduced drag and noise due to both a low friction surface coating and a dimpled surface like a golf ball so as to further reduce drag.
