Water was the only resource that could be used to produce energy which led Leonardo, who was exceptionally good with engineering, to study more about water and built a device to produce electricity. The device could measure humidity, was a steam-powered cannon, had many different waterwheels, and had great number of useful industrial machines powered by flowing water.
