The general idea is low profile, aimable air vents blowing up from desk level are the only way a standing desk is going to be practical.  There's not enough room next to a modern 4k monitor for any fans.  

So the idea came of somehow fixing 2 blower vents or a big row of vents to the sides or top of a keyboard to get more airflow during the summer.  Unlike existing USB fans which hardly move any air, this idea would attach to a big blower somewhere else via a vacuum hose.  The air would be blowing up from under the monitor.  It might be enough to justify going to a more compact dome keyboard instead of the "mechanical" keyboard of the last 4 years.  

The journey begins with shrinking the keyboard.  The mechanical keyboard really wasn't as satisfying as the internet claimed, despite conforming to the lion kingdom's favorite keyboard, the model M clones of the HP 9000.
