How was the steamboat helpful?

steamboats were an important part of American life throughout the 19th century. And invented by john Fitch. John Fitch was the inventor of the steamboat. Born in Pennsylvania and started his career as an artist, he travelled to England and started to be an engineer and shipbuilding. And then he started to design and building the submarine. But he stared all this in France but he wanted to be more successfully so he went to England. He was interested in steam engines only after 40 years of living. The steamboat helped by allowing the transportation against the current of rivers. Steamboats were able to travel both ways on a river, making it easy to transport goods and also more. Now, goods could be transported much easier. It also helped slaves, and transport people, one place to another. All they had to do was depend on was their muscles, but sometimes it took days to get back up stream. Now a day there barley any steamboats left because the ones left are now used to transporting tourists. The steamboat in made and ran on by wood, it works by puting wood in this capsule and the wood fire is going to eat up the fire and close the capsule and u have to help by giving it a push and the steam shoots up by making sure you have a lot of water in the boiler, A steamboat uses a steam engine similar to those on a steam locomotive. An external wood or coal fire heats water in a boiler but if u put cold water in the boiler it could ruin the whole steamboat, and not work. It has about 150 pounds of pressure. And while it runs it's super quite but not when it shoots out steam. John Fitch had a battle with James Rumsey, seeing who could build the best invention. The both had very similar inventions. John Fitch had four different steamboats it passed threw Philadelphia and Burlington, New Jersey. They were the same, such as the design, the way it runs, and what it needed. All it needed was hot water, wood. Just for it to make it run, sometimes it needed people to push the boat, but after a while, there arms would get sore after 10 minutes. There's many reasons why steamboats are helpful, first one it that the steamboat helps by making resource transformations quicker and easier.
