We just learned about the Sun and Planet Gear.
Another part of early machines was the North River Steamboat, also called the Clermont.
After all the pieces were invented to make a working steam engine, people started to try and use them to move things around.
In 1807 in New York, the North River Steamboat was built to take people along the Hudson River from New York City to Albany.
The boat was 142 feet long, and went about 5 miles per hour on the river.
It went about 150 miles, and took about 30 hours to make the trip!
Today in a car that takes about 2 hours, but back then it was a big deal.
