In this video, engine David Robert shows off his homemade V-12 solenoid engine, and it really is a sight to behold.
The overall design is configured to look like an internal combustion engine, but the actual mechanics are very different. Using magnetic solenoids to drive the crankshaft, this engine can run as either four or two stroke and can alternate between the two.
Built from 140 found parts, this engine was built for fun out of scrap materials after Robert successfully built a similar single cylinder prototype. It doesn’t crank out much torque, but its sure is a cool little novelty that any gearhead can enjoy!
