V8Paperengine
Make friend, the Lotharian, says,”This V8 Engine made entirely out of paper with the exception of a few parts (motor, wires, etc.), is fully functional. It features many moving parts which include: a compound crankshaft, a rapid cooling fan, 8 rods, 8 pistons and a complex compound gearbox. The engine is powered by 2 times 1.5V D Batteries and weighs 2.98kg. From start to finish this model took one year to design and construct. There is even a D.I.Y. kit in the works that will be released shortly.” Thanks Lotharian! [via] Link.
