Rotative Beam Engine

We just learned about the Newcomen Engine.

Another part of steam engine history is Rotative Beam Engine.

After the Newcomen Engine was built, people worked to make it even better.

In the old types of engines, the big rod that was moved by the steam was just pushed up and down.
For a rotative beam engine, one end of the beam uses a type of crank or gear to spin a wheel around.

This moving wheel could be used as a wheel to paddle a boat, or a wheel to move a train.

Carlini Base

We just learned about the Brown Station.

Another base in Antarctica is Carlini Base.

This base is owned by Argentina and is on the Antarctic peninsula, and holds about 60 people.
It was built in 1953, and is used mostly to study the weather, the animals and the ocean.

There are tourists that sometimes come to visit the station, so they have a radio station and a movie theater there for people.
In 2013 the rock band Metallica came down to Antarctica to play a concert, so that they could say they played on every continent.
Because the loud guitars, drums and speakers would hurt the ice, animals and environment down there, they played the concert with no amplifiers, just using their instruments in a special dome that kept in the sounds.

Living by this base are thousands of penguins and hundreds of sea lions that they watch over and study.
