Attention: Hollywood, Wall Street & Washington. Here's the real Power List, and you're not on it.
A lightweight fiberglass powerboat called Fountain Lightning can top 142 mph on still water. That's a powerful boat. A tug now under construction in China will tow an entire offshore oil-drilling platform into place, even on a restless sea. That's also a powerful boat. When talk turns to machine muscle, it's often about the most powerful engine that will fit into and move a machine. But to build an authentic Power List you have to ask what the measure and purpose of the power is: horsepower, torque, acceleration, top speed, hauling capacity, lift.
