These awesome Stirling "hot air" engines are crafted by a designer from the Netherlands who goes by the mob-worthy nickname "Jos the Finch." They run entirely off of the heat generated by waxinelichtjes, or squat tea light candles, and, depending on the design and how many candles are used, some run for several hours. They are mostly built out of brass, which gives 'em that swanky steampunk look.
