The first crude steam powered machine was built by Thomas Savery, of England, in 1698. Savery built his machine to help pump water out of coal mines. http://www.legeros.com/ralwake/photos/weblog/pivot/entry.php?id=4138 http://www.his.com/~pshapiro/steam.engines.html -
Nature of Electricity
Benjamin Franklin is perhaps the name most associated with electricity. In 1750, he sought to prove that lightning was caused by electricity by describing an experiment in which an electrical conductor would be used to extract power from a thundercloud. http://www.wisegeek.org/who-discovered-electricity.htm -
Automobile
In 1768, the first steam-powered automobile capable of human transportation was built by Nicolas-Joseph Cugnot. https://en.wikipedia.org/wiki/History_of_the_automobile -
Heat Engine
In thermodynamics, a heat engine is a system that converts heat or thermal energy—and chemical energy—to mechanical energy, which can then be used to do mechanical work. https://en.wikipedia.org/wiki/Heat_engine http://www.altdotenergy.com/2009/02/generate-electricity-with-waste-heat-engine/ -
Electric Motor
An electric motor is the fundamental electro-mechanical energy converter that uses the forces of electricity, magnetism, angular momentum, and inertia, as well as electro-magnetic theory, Faradays theories of electric current, and Tesla's theories of alternating current. http://www.seaperch.org/electric_motors https://commons.wikimedia.org/wiki/File:World%27s_first_electric_motor,_Jedlik%27s_motor_(1828).jpg -
Electrical Telegraph
An electrical telegraph is a telegraph that uses electrical signals, usually conveyed via dedicated telecommunication lines or radio. https://en.wikipedia.org/wiki/Electrical_telegraph -
