This futuristic-looking bladeless laminar vortex cyclonic homogenizing ceiling fan is looking for funding on Indiegogo, and is based on designs by Tesla. Fans with blades attempt to mix air and create indoor breezes by violently beating air into submission. The Exhale fan takes a different approach: a stack of rapidly spinning discs sucks up air and then flings it out to the sides utilizing a phenomenon called laminar flow. "It utilizes the science of laminar flow between an array of flat disks to efficiently move air throughout your environment.  This laminar movement creates a smooth uninterrupted airflow with virtually no noise." This evenly mixes air through an entire room as opposed to just directly beneath it.
