5x2 Chunk Airship

[soapboxstage]

So, one day, I was board with my small home. So I did this:

Its an airship that is 5 chunks by 2 chunks(Ignore the scaffolding at the bottom)

There is the engine room;
It has a steam engine(water evaporating on a magma block[infinite source])
This steam turns a turbine...
which turns a propeller at the back.

Here is the lifting mechanism;
It has the same concept as the engine room but with 4 large ones on a platform.
The water evaporates and makes steam. The steam is lighter than the air so it fills the balloon and causes a lifting force.

Please credit me if you use my engine design.

Note: I took the first picture from a cobblestone block, I made a pillar off of the side and broke the rest of the pillar
I WAS NOT FLYING
just to be safe
