“On display at Jaisalmer’s palace-museum is a device for cooling a room, which is fabricated from wood, metal and frames set with vetiver-grass (khus). This pre-modern cooler incorporates a manually turned spoked wooden wheel, which in turn moves small wooden fan-blades set within a large drum-like structure with wetted frames of khus on both sides. As the wheel turns, the fan-blades revolve, drawing and circulating khus cooled air through the chamber!”
