A new type of engine using bendConstant and bendTarget to produce power. The circle on the left sets a variable equal to its angle, and the bend hinge on the circle on the right adds to the variable and sets it as its bend target. This engine is far more powerful than my "Super Spring Engine" and both circles can be used as output. Also it is more reliable as there are no pistons that can break. Theoretically this engine produces infinite torque, but there may be limitations due to the flexibility of hinges.
