In 2008, Germany-based company Oliver Kessler Design released their THE SOLITAIRE punkah fan which uses a computer controlled brushless motor to mimic the slow pendular movement of a manually operated punkah fan. It features counterweights to balance the blade which can be as large as 1,5 m2 and runs efficiently, with as little as 10 W power consumption. THE SOLITAIRE punkah also features a safety stop that cuts off the motor if anything blocks the blade. In 2009 they released the SynchTool; it can wirelessly synchronize the movements of up to 999 of their punkah fans.
