water turned into steam. This steam filled the empty space of a closed tank of water with the only
opening as a pipe from the depth of the water. The water was forced out because of the pressure of
the expanding warm air. In the 1600's several scientists continued work on steam powered pumps.
Robert Boyle proposed the steam engine in 1678. During the 1680's a gunpowder explosion was
used to heat water. Jean de Hautefeuille tried to up water, and Dutch astronomer Christiaan
Huygens tried a piston in a cylinder. These experiments were the beginnings of a nuclear power-like
process. In 1712, Thomas Newcom and John Calley built their first successful steam engine.
Nicholas Cugnot built the first mechanically propelled road vehicle in 1769. Cugnot's vehicle was
powered through a two - cylinder piston connected steam engine. It used high pressure steam as the
power source.
