Stirling Fans

Rather than using the Seebeck effect, as chosen by other manufacturers, Vulcan and Warpfive use the Stirling Engine. First invented in 1816 as an engine to rival steam power. Considered more efficient and not dependent on the same amounts of fuel guzzled by the powerful steam engines of the same time, it was largely overlooked for large industrial use during the Industrial Revolution in the 1800s and early 1900s and kept to mainly low-power domestic uses.
