input OUTPUT Randall Wiseman was noodling around with engine designs some four years ago when he remembered the Spirograph that his nephew received one Christmas.

"I remembered playing with it, and that there was one gear relationship so that when you put the pen in a hole, it made an almost linear motion," Wiseman said. "I thought, that's no fun." Instead of a complicated design, all he got was a straight line.

That memory led Wiseman, a retired auto mechanic who lives in Bay St. Louis, Miss., to design a radical new crankshaft gear set, one that he claims can double engine efficiency and ...
