Laser Cutter + Water Jet = a New Manufacturing Tool.

Leonardo da Vinci always seemed to be hungry for new ideas, but sometimes he may have been just hungry. Some 500 years ago, he designed a roasting jack that powered an automatic rotisserie. It used hot air rising from a fireplace to spin a horizontal vane placed in the chimney above it. The vane was attached to a vertical rod that turned the spit, and, presumably, his dinner.

The jack was one of the world’s first turbines and engineers have been using the same principle inside jet engines and power plants ever since. Since high heat can make turbines more efficient, the hot sections of modern turbines operate at temperatures above 2,500 degrees Fahrenheit, much higher than Leonardo’s design and near the melting point of steel.
