Steam+Engine

= The Greek Steam Engine was not very useful. It was invented by Heron of Alexandia. Heron was born in 10 A.D in Alandria Roman, Egypt. I do not know when he died. Heron was a mathematician and engineer. Heron made the aeolipile (the steam engine). The aeolipile had no important uses. The only thing it did was make a cylinder turn. Though in some book it said the steam engine opened doors. The Steam engine was put to no work until 1st century A.D. The way Heron made the cylinder turn was by forcing some steam into small pipes to make the cylinder move. That is all I know about the Greek Steam Engine. = = =
