How can a steam make a boat move???

Answer 1

heat and pressure.....

Answer 2

Haha, ok, it is heat and pressure. BUT.  Here is what happens.  The steam is pressurized and it does through a duct, which then pushes a piston.  The piston will have a counter reaction, so basically the piston moves back and forth, one side pushed by the steam, the other side pushed by the counter reacting forces (which could be as simple as its own weight).  If you attach a shaft and some gears to the piston, the oscillating motion could be made into a rotational motion, then attach a propeller at the back of the boat, it makes the boat move forward.

Answer 3

As well as previous answers,  steam often turns turbine generators and then the electricity is used to power electric motors to turn the transmission which turns the shaft.  Steam can also turn a hydraulic pump which turns the shaft.  These two are mostly seen on large cargo ships.  The days of steam are nearly past as diesel or diesel electric is the modern way to build.

Answer 4

Steam makes the turbines move, which in turn makes the propellers at the bottom of the ship whirl thus moving the ship.

Answer 5

Connect a rope to it, attach it to your truck, pull it. Another option, drill holes in the bottom, it should move downward, just a few out of the box options.

Answer 6

I have a very simple toy steam boat that uses a tiny candle for heat. You fill up the tubes with water, light the candle, and a few mins later, your slowly moving along. One tube has steam coming out of it creating force causing the other tube to creat a vacuum to suck in more water. Its a very simple steam engine.

There are other ways, using steam to propel pistons or turbines, then attaching them to flywheels and those to propellers of some kind as other people have mentioned.
