I have adopted the story from Robinson Crusoe.
My own twist of the story is he is a physicist and a professor at one of Universities in UK.
He wants to figure out more stuff in his field and builds Time Machine to travel the future.
I have set the location in 1850s' Oxford. Energy source for Time Travel is Steam Engine.
I guess in 1850 Steam Engine was powerful energy source.
So I have referenced them to build Time Machine.
I build window frame and main building in Google Sketchup to see accurate scale.
