Sam doesn't know that there are some big heads thinking about him day and night. He knew some trouble will be coming towards him, but he doesn't know to what extent.
Right now, he is inside the second floor of the tower, making some machines. One of them is an old classic. The steam-engine.
There are not one but multiple of them in varying sizes.
Sam gave the auxiliary components of these engines for manufacturing and for some other machines which will help him in production progress.
There are some machines which he assembled after the steam engine and they are milling machine, lathe machine, air compressor, etc.
At first, he wanted to design a methane fuel-based engine but gave up on the idea later as there is no need to waste time on that. All he needs is something that gives him required shaft power and as the time is running tight, he can deal with the whole methane engine thing later.
