Power and energy / Jackson, Tom

The simplest machines are the lever, wheel and axle, pulley, ramp, and screw. The electric motor was first invented in 1832, and was used commercially for the first time 41 years later. Examine significant developments in the generation and use of power in Power and Energy, one of the titles in the Technology and Innovation series.

This book traces the progress of technology used to create energy to run machines from ancient watermills and windmills to today's biofuels, solar cells, and other renewable resources.
