Smallest V-12 On the Face of the Earth

This gentleman deserves some serious props for designing, building, and sharing this fantastic creation. What you see here is the world's smallest V-12 ever produced. Although it does not run on any kind of combustible fuel, it works in exactly the same manner. I was completely transfixed for the first seven minutes of the video, because anyone that knows what those parts are and how tiny they are, will know that it is an incredible feat of engineering. Here is the Youtube description translated into English.


"V-12 engine with compressed air injection, hand made using traditional methods:12 cm3 of displacement, the diameter of the cylinder is 11,3 mm,the stroke of the pistons 10mm, it works with only 0,1kg/cm2. It is constructed with stainless steel, aluminum, and bronze. Patelo dedicated this engine to his grandchildren: Sara, Carmen, Jose and Pablo. This engine is for education, exhibitions, etc., that is the reason to work with compressed air, to avoid contamination. He has made the plans and all parts, except the screws."
